Troubleshooting OGG Char datatype from mysql to ogg fill chr(0)

前几年处理过一个<当C语言的程序处理 chr(0) or ‘\0’ 时的ORA-01008 Case>故障案例， 近期又遇到一个案例是在Golden Gate同步数据时遇到的问题，发现ogg在同步时对于char类型的字段，不足指定长度时，OGG使用的是chr(0)补充， 而对于已有数据是默认chr 32(空格)补充，导致无法匹配问题。

一套mysql to oracle的OGG同步环境，源端mysql—字符集utf8，目标端oracle—字符集16gbk， 某年某月某一天告警OGG进程异常中断，通过查看日志发现是discard文件写满了，discard内容如下：

No data found
Operation failed at seqno 20 rba 13264
Discarding record on action DISCARD on error 1403
Problem replicating SCHEMA1.TABLE1 to SCHEMA2.TABLE2.

MARKET_TYPE = 1
000000: 31                                              |1               |

REMARK = NULL
ORDER_STATUS = 22
PRINT_RECEIPT = 0
ORDER_TYPE = 4

Note:
从报错看像是个多列记录的update, 报错的原因是not data found,记录未匹配到。手动根据其中一列（非PK列）校验，目测目标库中也是存在该记录，未发现明显异常。

这时常用的做法要么把应用打印出sql,手动去执行；
logdump trail file对比数据是否在目标库存在；


后来分析存在以下几种上情况：
1， ogg insert同步正常
2， 对于ogg insert同步到目标端的，后期ogg update 同步正常。
3， 对于非使用ogg初始化同步到目标端的，后期ogg update同步有正常， 也有不正常，提示上面的错误记录无法匹配。

去oracle数据库中使用dump函数对比记录不同时发现，PK列，为char(20)， 该类型在oracle中处理时，如果是insert值不足指定长度时，后面用空格补充。对比发现
对于以空格结尾的数据也就是非OGG初始化的数据，OGG同步异常；而使用OGG同步insert的记录，列后补充的是chr(0);

从ogg 转换为SQL输出后发现insert的数据对应补充确实是\00 (chr(0))如下图：

这也就解释了上面的问题，如果PK列值的长度刚好满足字段char长度，OGG同步正常， 而对于初始化补“空格”，而OGG匹配时补”\00″的就无法匹配。

SQL> drop table test;
Table dropped.

SQL> create table test(v char(10));
Table created.

SQL> insert into test values ('a');
1 row created.

SQL> select length(v) from test;
 LENGTH(V)
----------
        10
SQL> select dump(v) from test;

DUMP(V)
---------------------------------------------
Typ=96 Len=10: 97,32,32,32,32,32,32,32,32,32

SQL> select * from test where v='a';
V
----------
a

SQL> select * from test where v='a           ';
V
----------
a

SQL> insert into test values ('b'||chr(0));

1 row created.

SQL> select * from test where v='b';
no rows selected

SQL> select * from test where v='b    ';
no rows selected

SQL> select * from test where v like 'b%';
V
----------
b

所以除了上面同步的问题，对于用chr 0 补充对于应用检索存在问题，对此问题联系到了oracle原厂，推测是字符集问题，但还应该是要OGG去解决。变通的解决方法将源端MySQL字段类型更改为varchar，目标端Oracle更改为varchar2问题得以解决。

最近遇到一个案例AIX 7.2 挂转NFS v3(源为Suse 11), RMAN restore 控制文件到NFS上 hang， 检查了AIX端mount选项和权限一切正常，在oracle用户下同样可以cp 和vi 文件，最终发现是因为rpcbind服务未启动导致，简单记录。

1, 检查NFS 版本
mount |grep nfs

2, 检查oracle执行文件权限
ls -l $ORACLE_HOME/bin

3, 检查DB ALert log和rman log

4, debug
操作系统使用truss -aefp <rman pid> -o rman_debug.tuc -d

rman> debug on
rman> xxxx
— or —
rman target / debug trace=xxxx.log

5, 尝试restore 到本地文件系统

restore 到本地文件系统是OK, 原因出在NFS。

— RMAN debug trace

Note:
RAUT command 在sleep 10秒反复尝试，猜测是Remore AUTH 认证相关。 查询NFS 认证相关的服务发现有个rpc NFS认证服务，NFS在文件传送或信息传送过程中依赖于RPC协议，去服务端查询RPC服务，网络文件系统（NFS）就是基于RPC协议工作的，NFS本身是没有提供信息传输的协议和功能的，但NFS却能让我们通过网络进行资料的分享，这是因为NFS使用了传输协议用到这个RPC功能的。可以这么理解RPC和NFS的关系：NFS是一个文件系统，而RPC是负责负责信息的传输。如NFS(客户端)——-Portmap(客户端)——Portmap(服务端)——NFS(服务端),实现RPC协议的软件是RPCbind程序包，进程名称是portmappe, 在rpcbind 使用RPC服务映射到它们所监听的端口，所以NFS依赖RPCbind 和RPCbind.socket 服务。使用rpcinfo查看rpc相关的服务。NFS服务要先检查rpcbind。

发现该服务存在问题未running状态，检查OS LOG

Jun 01 03:57:48 nfs.anbob.com systemd[1]: rpcbind.socket failed to listen on sockets: Address already in use
Jun 01 03:57:48 nfs.anbob.com systemd[1]: Failed to listen on RPCbind Server Activation Socket.
-- Subject: Unit rpcbind.socket has failed

可以看到rpcbind.socket启动失败， Bug 1422090 – Rpcbind does not work in the container 发现有相似BUG. 有些案例是因为IPV6的原因（报错rpcbind.socket failed to listen on sockets: Address family not supported by protocol），影响rpcbind.socket服务， 搞定了rpcbind.socket服务，RMAN 备份也恢复了正常。

其它如果存在防火墙存在时，可以考虑固定NFS端口，增加防火墙访问策略。

但是注意rpcbind存在安全风险，需要配置防火墙加固。 NFS服务器在Red Hat Enterprise Linux 7中支持NFSv2，NFSv3和NFSv4连接。但是，您也可以将NFS配置为仅支持NFS版本4.0和更高版本。由于NFSv4不需要该rpcbind服务在网络上进行侦听，因此可以最大程度地减少系统上打开的端口和正在运行的服务的数量。

当您的NFS服务器配置为仅NFSv4时，尝试使用NFSv2或NFSv3挂载共享的客户端将失败，并显示以下错误：
不支持请求的NFS版本或传输协议。

Troubleshooting JDBC(JVM) connection timeout (java.security.egd)

同事遇到的一个jdbc的应用在执行sql时出现间断性超时错误， strace时会显示 etimedout (connection timed out) 的字样， 网络抓包存在回包延迟现象，最后应用的配置了java.security.egd JVM选项， 问题得到解决， 这个问题原理不是很理解， 也需要是JVM 生成随机端口调用时出现了延迟(just I guess). 简单记录

Avoiding JVM delays caused by random number generation 记录对于UNIX平台，默认情况下，Oracle JVM中用于随机数生成的库依赖于/ dev / random。这可能会阻止WebLogic Server进程，因为在某些操作系统上，/ dev / random在返回结果之前会等待主机上生成一定量的“噪声”。尽管/ dev / random更安全，但是如果默认的JVM配置延迟了WebLogic Server的启动，建议使用/ dev / urandom。

编辑$JAVA_HOME/jre/lib/security/java.security 配置 “java.security.egd” ：
-D java.security.egd=file:/dev/./urandom

如果java应用程序使用java.security.SecureRandom 出现hang, 尝试添加系统属性-Djava.security。使用/dev/urandom代替/dev/randomdom。但在Java 6和Java 7中，该设置似乎不起作用。

解决方法：
Specify -Djava.security.egd=file:/dev/./urandom instead of -Djava.security.egd=file:/dev/urandom
— or —
Upgrade to Java 8

当我们设置java.security.egd JVM属性时，安全提供程序可以使用它来覆盖securerandom.source中配置的属性。

一起，java.security.egd和securerandom.source其中控制熵收集设备，当我们使用（EGD）将用作种子数据的主要来源的SecureRandom来产生随机数。

对于我这从事10余年的oracle dba从未像今年这样感觉到压力， 国产开源数据库铺天盖地的宣传，我依旧建议不要满目随大流式换库，因为数据库迁移经验对于不同的业务场景并非可以完全复制，昨天想装个openGauss小测一下，发现2.0新鲜发布， OpenGauss社区可以下载安装介质，openGauss内核源自PostgreSQL 9.2，是一款开源关系型数据库管理系统，采用木兰宽松许可证v2发行。

Query dba_autotask_client slow?

最近在整理巡检脚本时，发现在执行select client_name,status from dba_autotask_client;时耗时几十秒， 该SQL只是想检查数据库级的自动任务是否启用(如自动收集统计信息)， 返回的记录也并不多，只关心状态，如下输出.

SQL> select client_name,status from dba_autotask_client;

CLIENT_NAME                                                      STATUS
---------------------------------------------------------------- --------
sql tuning advisor                                               ENABLED

auto space advisor                                               ENABLED

但是细看执行计划其实涉及的对象较多， 使用sqlmonitor可以明确，执行时间90%+是花在SCHEDULER$_EVENT_LOG的FULL TABLE SCAN, 刚好这个库有近200个JOB or scheduler 所以日志非常大，该表记录近150万， 可以使用下面的方法清理JOB 日志。

exec DBMS_SCHEDULER.PURGE_LOG();
-- or --
truncate table sys.scheduler$_event_log;

所以如果只是需要上面的查询结果可以使用VIEW 定义中的部分SQL:

SELECT C.CNAME_KETCL,
DECODE(dbms_auto_task.get_client_status_override(CR.CLIENT_ID),
1, 'DISABLED',
decode(CR.STATUS, 2, 'ENABLED',  1, 'DISABLED', 'INVALID'))

案例: 11g R2(11.2.0.4) RAC addnode on RHEL7（Linux7）问题小结

April 29, 2021, 8:12 pm

最近一例在11.2.0.4 2NODES RAC on linux7 增加节点时不是很顺利，此版本是ORACLE的认证版本但是还是兼容性还不是那么顺滑，9年前分享过在linux6上addnode还相对顺利《Oracle 11g R2 RAC addnode (增加RAC节点) 实践和注意事项》。 遇到的问题也较多涉及IB,网络，bug， 损坏，补丁等，简单记录。

1， IB心跳网不通
addnode前需要检查现存节点是否正常，发现node2心跳不通，使用的是IB全家桶， 进看IB状态

[oracle@anbob001:/home/oracle]$ethtool ib0
Settings for ib0:
        Supported ports: [ ]

Dec 13 23:35:02 anbob002 python: File "/opt/zdata/compute/python/lib/python2.7/logging/__init__.py", line 943, in _open
Dec 13 23:35:02 anbob002 kernel: ib1: transmit timeout: latency 1022653 msecs
Dec 13 23:35:02 anbob002 kernel: ib1: queue (5) stopped, tx_head 2318340524, tx_tail 2318340429
Dec 13 23:35:12 anbob002 kernel: ib1: transmit timeout: latency 1032669 msecs
Dec 13 23:35:12 anbob002 kernel: ib1: queue (5) stopped, tx_head 2318340524, tx_tail 2318340429
Dec 13 23:35:22 anbob002 kernel: ib1: transmit timeout: latency 1042653 msecs

该问题为IB驱动BUG, IB堵塞，暂时可以通过REBOOT解决。

2， addnode 耗时久、流量小
addnode会传送执行节点的文件scp到新节点，对于trace logfile较多如adump，几十万的trace小文件传递， 目标root.sh时同样还要对这些文件授权，很有可能浪费几个小时。

解决在增加节点前清理trace文件。

3， addnode 失败 with PRCF-2015 PRCF-2002
addnode中间连接断开，多次尝试相同现象，心跳网虽是IB，但这个环境的public network是1000M电口， 但理论也不应该存在瓶颈，addnode使用的是public network.

在文件传输时ping远程节点达40ms时延，网络不是很好。文件传速理论并不是firewall kill的idle connect， Oracle存在一个bug较匹配，因为使用scp服务，默认SSH服务的最大并发不足，oracle建议调整加大ssh server端maxstartups ，MaxStartups 默认是10:30：60 “start:rate:full”,表示最大并发10个，如果超过后会有rate 30/100% 可能性失败，如果超过 full 60时会肯定失败，但是只是限制未认证的连接， 需要重启sshd服务。 建议加大到40,但是重试还是失败，继续加大到100, 100:30:100 后重试还是失败， 问题还是网络太差导致。

4， 网络差

这样的网络就可能会导致数据包发送失败，涉及网络包失败重传优化问题，RFC2018提供了一个SACK的方法，与报文的确认机制相关，SACK(Selective Acknowledgment)，SACK是一个TCP的选项，来允许TCP单独确认非连续的片段，用于告知真正丢失的包，只重传丢失的片段。当前是禁用的，下面尝试启用SACK

sysctl -w net.ipv4.tcp_sack=1

再次尝试addnode ，成功解决。
tcp_sack 不是个万能药，如果你注意EXADATA中的配置，最值实践还是禁用SACK的，并且在OEL UEK4中同样存在启用TCP_SACK后性能变差。 遇到问题时建议测试一下，事实胜于雄辩。

5， HAS 无法启动
这是11G 在LINUX7上的著名的问题，因为有init.d改为systemd，ohasd服务需要在root.sh前安装补丁，或手动创建servcie，眼快手极的手动启服务。直到看到init.ohasd run进程。补丁安装18370031也可以。

注意root.sh 如果失败了，从11.2.0.2开始是可以重复的跑的继续安装。

6, crs-10131 /var/tmp/.oracle/npohasd mkfifo: cannot create fifo ‘/var/tmp/.oracle/npohasd’: file exists
如果没有看到 /etc/init.d/init.ohasd run这样的进程，说明ohasd服务都没启 看日志文件提示

crs-10131 /var/tmp/.oracle/npohasd mkfifo: cannot create fifo '/var/tmp/.oracle/npohasd': file exists

是因为之前网络传失败时/var/tmp/.oracle/npohasd文件传送了过来，文件的生成时间早于进程启动时间， 建议删除。

7， PROCL-26 OLR initalization failured, rc=26
再次尝试root.sh,又失败了

2021-04-27 23:01:46.275: [  OCROSD][1228334000]utread:3: Problem reading buffer 1907f000 buflen 4096 retval 0 phy_offset 102400 retry 5

2021-04-27 23:01:46.277: [ default][1228334000][PANIC] OHASD exiting; Could not init OLR

这原因是因为OLR损坏了， root.sh会修复，

Root.sh Failed USM Driver Install Actions Failed On Second Node ( ACFS-11022 ) (Doc ID 1477313.1) 之前RAC是安装过17475946 patch的。

这环境看来有点糟糕， 清理了，重新来addnode, root.sh

8，node1 addnoe 会提示node3已存在，需要清理一下。

#as  root 
$GRID_HOME/bin/crsctl delete node -n anbob003
# as grid
./runInstaller -updateNodeList ORACLE_HOME=CRS_home  "CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE

解决了addnode

node3再次root.sh时又失败，提示

crs-4046 invalid coracle clusterware configuration
crs-4000 command create failed, or completed with errors

解决这个问题执行:

# /crs/install/rootcrs.pl -deconfig -force -verbose

9， ACFS-9459  错误
但是deconfig又报如下错误

ps -ef|grpe u01

并没有ORACLE_HOME下的活动进程，我认为主要是解决ACFS-9459 错误， 不支持当前的操作系统内核，相关的bug 还有21233961.

cd /u01/app/grid/11.2.0/install/usm/Novell/SLES11/x86_64
mv 3.0.61-0.9 3.0.61-0.9_bak
ln -s 3.0.13-0.27 3.10.0-957.21

这种link版本的方式无法解决，后来回滚了node3 上的ACFS补丁， deconfig成功， 同时root.sh也顺利完成。 判断应该是oracle bug,在安装顺序上ACFS补丁有冲突。

Alert: Linux平台使用udev绑定ASM存储时，频繁的systemd-udevd导致CPU使用率高

最近查询时发现一套Linux(Suse Linux 12)平台上的Oracle主机CPU使用率偏高，该数据库并不繁忙，从top中发现大量的systemd-udevd 进程，是CPU的主要花费进程， 该现象并不局限于Suse，RHEL和OEL同样可能存在这些现象， 通常是当udev加载时，即使系统当前并无任何磁盘存储的调整，也会存在该现象。

Note:
可以发现操作系统上聚合以后的设备和udev 创建的ASM-DISK 链接设备的时间也一直在改变。

检查OS 日志中并无报错信息。当前也并未影响ASM使用。

udev rule的规则文件内容是有以下脚本生成.

# # append to /etc/udev/rules.d/99-oracle-asmdevices.rules
for i in b c d e f ;
do
echo "KERNEL==\"sddl*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sddl$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""      
done

当Oracle进程打开该设备进行write然后close时，这会合成一个change事件。 任何具有ACTION ==“ add | change”的udev规则都将被重新加载。udev 对于inotify有两个option: watch(default)和nowatch.

watch
       Watch the device node with inotify, when closed after being opened for writing, a change uevent will be synthesised.

nowatch
       Disable the watching of a device node with inotify.

对于oracle读写文件是正常形为，可以抑制一下正常的change事件，禁用这些ORACLE ASM设备inotify watch. 使用以方法:

o suppress the false positive change events disable the inotify watch for devices used for Oracle ASM using following steps:

1, 在文件/etc/udev/rules.d/99-oracle-asmdevices.rules 末尾追加

ACTION=="add|change", KERNEL=="sd*", OPTIONS:="nowatch"

2，重启udev规则文件，使以上修改在内存生效。–可在线做

$ /sbin/udevadm control --reload-rules
$ /sbin/udevadm trigger --type=devices --action=change

此问题已解决，但是oracle建议对于未出现udev进程性能问题的环境，可以保护原来的默认watch OPTIONS.

Linux Kdump for system panics

June 3, 2021, 7:06 pm
$

The kdump procedure

The received warning means the kdump operation might fail and the crashdump parameter should be configured correctly. This is the procedure of kdumping:

1. The normal kernel is booted with crashkernel=… as a kernel option, reserving some memory for the kdump kernel. The memory reserved by the crashkernel parameter is not available to the normal kernel during regular operation. It is reserved for later use by the kdump kernel.
2. The system panics.
3. The kdump kernel is booted using kexec, it used the memory area that was reserved w/ the crashkernel parameter.
4. The normal kernel’s memory is captured into a vmcore.

Note: Not reserving enough memory for the kdump kernel can lead to the kdump operation failing.

Configuring crashkernel

RHEL6.0 and RHEL6.1 kernels

ram size crashkernel parameter ram / crashkernel factor
>0GB 128MB 15
>2GB 256MB 23
>6GB 512MB 15
>8GB 768MB 31

RHEL6.2 (and later) kernels

Starting with RHEL6.2 kernels crashkernel=auto should be used. The kernel will automatically reserve an appropriate amount of memory for the kdump kernel. crashkernel is configured   in file /etc/grub.conf

Keep in mind that it is an algorithmically calculated memory reservation and might not meet the needs of all systems (Especially for configurations with lots of IO cards and loaded drivers). So always make sure that memory reserved by crashkernel=auto is sufficient for the target machine by testing kdump. If it is not, reserve more memory by syntax crashkernel= XM (X is amount of memory to be reserved in mega bytes).

Additionally some improvements have been made in the RHEL6.2 kernel which have reduced the overall memory requirements of kdump.

Note: It is recommended to test and verify that kdump is working on all systems after installation of all applications. The memory reserved by crashkernel=auto takes only typical RHEL configurations into account. Some hardware and larger configurations with many option cards may not work well with with crashkernel=auto, in this case the use of crashkernel=512M or more may be a recommended size to start.

   Prior to the 6.3GA release, crashkernel=auto will only reserve memory on systems with 4GB or more physical memory. If the system has less than 4GB of memory the memory must be reserved by explicitly requesting the reservation size, for example: crashkernel=128M. Since the 6.3GA release (kernel-2.6.32-279.el6), this limit has been lowered to 2GB.

    Some environments still require manual configuration of the crashkernel option, for example if dumps to very large local filesystems are performed.

 RHEL 7

crashkernel is configured in the GRUB_CMDLINE_LINUX line in /etc/default/grub:

GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=rhel00/root rd.lvm.lv=rhel00/swap
 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

After modifying /etc/default/grub, regenerate the GRUB2 configuration using the edited default file. If your system uses BIOS firmware, execute the following command:

# grub2-mkconfig -o /boot/grub2/grub.cfg

On a system with UEFI firmware, execute the following instead:

# grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg

Note:

RHEL7 with crashkernel=auto will only reserve memory on systems with 2GB or more physical memory. If the system has less than 2GB of memory the memory must be reserved by explicitly requesting the reservation size, for example: crashkernel=128M.  Some environments still require manual configuration of the crashkernel option, e.g A 2TB oracle databasehost crash ,kdump not work,  to modify crashkernel=2048M, then it work fine.

how much memory was reserved for the kdump kernel?

This is available when executing cat /proc/cmdline. Even when the kernel was started with crashkernel=auto then /proc/cmdline will contain the computed value that got reserved.

  • cat /proc/cmdline
  • cat /sys/kernel/kexec_crash_size

Where to find generated vmcores

When the hypervisor comes back up, the vmcore can be found by default under /var/crash/: (SLES is /var/log/dump)

# egrep '^path' /etc/kdump.conf
path /var/crash

The crash tool in kernel-debuginfo for analysis.

How to test kump work?

# echo c > /proc/sysrq-trigger

Note:  This command will cause the operating system to crash, do not test during the run-time of the industry branch.

LMSn not running in RT (real time) mode Oracle 19c RAC？

June 4, 2021, 1:22 am

Oracle 希望在数据库主机CPU使用率枯竭时，尽可能让核心的几个后台进程可以最大优先级获取CPU, 虽然CPU过高会导致I/O 响应时间变长和网络延迟增加，也会间接影响数据的整体性能。从oracle 10g开始是有隐藏参数_high_priority_processes控制哪些参数是更高优先级,在19c参数_highest_priority_processes控制最高优先级。在 10.2 版本中，Oracle缺省的对RAC的核心进程LMS* 设置高优先级，在11g版本对 LMS*||VKTM 设置高优先级，在19C版本对VKTM是最高优先级，提供了更多的进程对LMS*|LM*|LCK0|GCR*|CKPT|DBRM|RMS0|LGWR|CR*|RMV* 配置更高优先级 。记的在10.2.0.3前好像有个bug 会导致进程过高使用CPU，目前的主流版本问题较少。 最近有客户遇到CPU 使用率超过90%时GC问题较为突出，在查看LMS时发现没有在RT模式引起了注意，在19c中 LMS还是有一些变化，下面简单的记录。

在Linux平台上，进程的内核调用模式分为三类：

TS – SCHED_OTHER (SCHED_NORMAL) ，这是分时调度策略，缺省的通用级别；
FF – SCHED_FIFO，这是实时调度策略，先进先出；
RR – SCHED_RR，实时调度策略，时间片轮转;

先看一个正常环境 oracle 19c RAC 2-nodes on RHEL 7.8

对于这个环境的owner 和权限都是错的， 修正后重启实例就可以解决。

也可以使用root用户使用chrt在线修改进程级为RR mode

19c(19.4) RAC crash CSSD with ASSERT clsssc.c error On LinuxONE

June 7, 2021, 6:48 am

这是一套Oracle 19.4 的RAC 环境，硬件是IBM 大机LinuxONE(Zlinux), 节点出几次重启目前已确认是由于oracle代码级bug，cssd错误的Reference count 记录为0，导致再次ASSERT资源时异常终止。前段时间有朋友说有一家著名的第三方公司在到处宣传19.4是目前ORACLE 19C里较稳定的版本，如当前的19.8测出了2个bug, 我在想哪个版本还没几百个bug. 如oracle所说他们在19.10修复了大量的内存级错误，当前还是建议安装最新的RU(19.11). 这里记录一下这个问题希望能节约一些相同问题的时间。

Transportable Tablespace Failed with ORA-39360(TSLTZ datatype), How to continue ?

June 10, 2021, 12:43 am

前几日在做oracle 迁移升级使用FTTS 从11.2.0.4 升级到19c pdb时，因为对象包含数据类型TimeStamp with Local Time Zone(TSLTZ )， 导入matadata过程中报错ORA-39360而终止，报错如下:
Full Transportable tablespace import fails with:
ORA-39360: Table “<<owner>>”.”<<<table name>>” was skipped due to transportable import and TSLTZ issues resulting from time zone mismatch.

传输表空间(TTS)没有办法hold住不同的timezone 版本之间的数据库导入，通过 V$TIMEZONE_FILE.version可以查询timezone版本。可传输表空间模式下时区文件版本的注意事项 ：

Considerations for Time Zone File Versions in Transportable Tablespace Mode

Restriction : Jobs performed in transportable tablespace mode have the following requirements concerning time zone file versions: If the source is Oracle Database 11g release 2 (11.2.0.2) or later and there are tables in the transportable set that use TIMESTAMP WITH TIMEZONE (TSTZ) columns, then the time zone file version on the target database must exactly match the time zone file version on the source database.

If the source is earlier than Oracle Database 11g release 2 (11.2.0.2), then the time zone file version must be the same on the source and target database for all transportable jobs regardless of whether the transportable set uses TSTZ columns.

If these requirements are not met, then the import job aborts before anything is imported. This is because if the import job were allowed to import the objects, there might be inconsistent results when tables with TSTZ columns were read.

ORA-39339: Table string was skipped due to transportable import and TSTZ issues resulting from time zone version mismatch.
Cause: The source database is at a different time zone version than the target database and this table contains TIMESTAMP WITH TIME ZONE data.

Action: Convert the target database to the same time zone version as the source database or use Oracle Data Pump with conventional data movement to export then import this table.

上面是关于TSTZ 列类型，本地TTS过程发现是TSTZ导入顺利，但TSLTZ的对象未导入，需要单独处理。可以尝试exclude这些带TSLTZ的对象，而当时时间紧认为是FXTTS存在缺陷，重导metadata改用TTS， 但是TTS再次直接导入时提示表空间已存在，因为上次的FXTTS impdp时已导入了部分数据，如何再继续呢？

在当前时间点tablespace和它的datafile header仍旧是read-only, 数据文件路径和表空间已经注册到了目标数据库中，现在在tablespace修改为”read-write”前，我们还可以删除表空间(只删metadata)，重新导入表空间的metadata. 而不用再重新从源库copy datafile，这些datafile大目标库路径下已经是read-only状态。

执行下面的命令删除表空间继续导入tablespace metadata.:

drop tablespace ttstbs including contents keep datafiles;

上面的命令只会从目标数据库中删除表空间元数据条目，以便可以重新导入。请注意，此命令不会从目标位置删除数据文件。

再次执行导入

impdp  …..

Oracle Development declared that it as an “Expected Behavior”
Starting from 12.1, during the TTS import operation, the tablespaces (datafile headers) are put into read-write mode intermittently in order to fix up TSTZ table columns and clean up unused segments in the datafiles.
This functionality was implemented based on many Customer’s request.  And, hence, this cannot be reversed.  Note that, it intermittently only changes the status to “read-write” and the final status will still be “read-only” only.

 

Note:

in TTS Import, the final status of tablespace is set to READ-ONLY though it intermittently changes the status to READ-WRITE.
Whereas, in FULL-TTS Import, Oracle by default sets the final status of tablespaces to READ-WRITE once the import operation is completed.

检查带有TIME ZONE的对象

select c.owner || '.' || c.table_name || '(' || c.column_name || ') -' || c.data_type || ' ' col 
from dba_tab_cols c, dba_objects o 
where c.data_type like '%TIME ZONE' 
and c.owner=o.owner

and o.object_type = 'TABLE'

OGG extract checkpoints

STARTUP CHECKPOINT

Whenever an Extract process is started, it makes it’s first checkpoint in the data source. The first checkpoint made in the data source when the extract process starts is the STARTUP CHECKPOINT.

Current Read Checkpoint

The Extract process reads from the Redo Logs or Archive Log files. This Checkpoint shows the current read position of the Extract process. It shows the information of the extract process where currently it is reading like, which is the current redo log or archive log file.

Recovery Checkpoint

the extract process not only captures the committed changes from the redo or archive log files but also keeps track of all the open transaction. This is the checkpoint which shows the Oldest Open transaction in the database.

CURRENT WRITE CHECKPOINT

Extract process captures the changes from the redo log or archive log files and writes these changes to the Trail files called Local Trails. The CURRENT WRITE CHECKPOINT show the information of the extract process where it is currently writing. It means the information like, to which trail file sequence and RBA it is currently writing to.

BR  Recovery Checkpoint

“Bounded Recovery” is only for Oracle databases,“Bounded Recovery” is a component of the general extract checkpointing facility. This component of the extract guarantees an efficient recovery after an extract stops for any reason, no matter how many uncommitted transactions are currently outstanding. The Bounded Recovery parameter sets an upper boundary for the maximum amount of time that an extract is needed to recover to the point where it stopped before continuing normal processing. The default settings for “Bounded Recovery” is set to 4 hours

在Oracle GoldenGate版本11.x中，引入了Bounded Recovery(BR)的概念，即允许extract对于长事务(long running transaction 比BRINTERVAL指定值更长的事务)写入到本地BR目录。当extract重启时，它会首先读取BR文件，取而代之读取恢复检查点指定的归档日志，这样有助于提升性能以及减少对旧归档文件的依赖。 但是当在RAC环境中使用Bounded Recovery(BR)特性来恢复一个异常abend掉的extract的话，小概率可能会遇到extract hang住或丢失特性的事务。

What defines a long-running transaction for Oracle GoldenGate?
Transactions in Oracle GoldenGate are long-running if the transaction has been open longer than one (1) “Bounded Recovery” interval.
A “bounded recovery interval” is the amount of time between “Bounded Recovery checkpoints” which persists the current state and data of the extract to disk.  “Bounded Recovery checkpoints” are used to identify a recovery position between tow “Bounded Recovery intervals”.  The extract will pick up from the last “bounded recovery checkpoint”, instead of processing from the log position where the open long-running transaction first appeared.
What is the maximum Bounded Recovery time?
The maximum bounded recovery time is no more than twice the current “Bounded Recovery checkpoint” interval.

“Bounded Recovery” can be changed by updating the extract parameter file with the following parameter:

1
2
3
4
5
6
7
BR
[, BRDIR directory]
[, BRINTERVAL number {M | H}]
[, BRKEEPSTALEFILES]
[, BROFF]
[, BROFFONFAILURE]
[, BRRESET]

extract hung when using BR and new objects are added to extract With BR setup, when new objects (table, sequence, DDL, et al) are including in the extract, restarted extract will pick up more data that causes the producer queue limit (a fixed number) used by BR be reached. Because the extract is still in BR recovery, the consumer thread is stopped and not processing data from the producer queues. This caused a deadlock, and the extract will appear hung.

when new object is added to an extract. All the archived logs since recovery checkpoint need to be available. ggsci> start extract xxx, BRRESET

Cause Under these conditions, this may be a problem with the Bounded Recovery Checkpoint file. It is likely corrupted. Solution The solution is to reset the Bounded Recovery Checkpoint file when restarting the extract like: GGSCI> start extract xxx BRRESET

BRRESET
BRRESET forces Extract to use normal recovery for the current run, and then turn Bounded Recovery back on after the recovery is complete. Its purpose is for the rare cases when Bounded Recovery does not revert to normal recovery if it encounters an error. Bounded Recovery will be enabled during runtime. Consult Oracle Support before using this option.

Extract is in recovery mode until it has read all records from the recovery checkpoint to the current checkpoint. This is expected behavior.

If this is a planned STOP for EXTRACT, do

ggsci > info <extract>, showch

For each Thread, check that the difference between the Recovery Checkpoint Sequence and the Current Checkpoint Sequence is not too great.
This implies that extract is currently tracking a long transaction. To check what transactions are currently being tracked on a RUNNING extract, do

ggsci > send <extract> , showtrans

Check the Transaction ID (XID for Oracle DB) from the database and wait for the long transactions to commit.

Therefore before planning to stop extract check for long transactions before doing so to prevent long recovery for extract.

这个案例是开始因为有实例突然crash, 应该是存在大事务回滚等，后来因为备份任务删除了归档日志，extract进程重启后无法读取，在restore archivelog后，extract进程依旧无法移动，判断是BR损坏或其它原因导致extract进程hang,  在移除BR文件恢复到normal recover后，读取归档进程运行正常， 当然也可以尝试ggsci> start extract xxx, BRRESET  强制extract进程使用normal recovery启动。

 常用检查方法

# check checkpoint

GGSCI > info xxx, showch

# check transaction

GGSCI > info xxx, showch

# check log

GGSCI > view report   xxx

# check transaction in db

 select b.inst_id,b.sid,b.serial#, b.username,wait_class, state,SECONDS_IN_WAIT, XIDUSN||'.'||XIDSLOT||'.'||XIDSQN "XID", (START_SCNW * 4294967296) + START_SCNB "Start SCN" ,SES_ADDR

oracle 11g后引入adrci 仓库管理trace文件，12c后更把把GI和DB全转到了adrci， 我还是比较喜欢用它小工具，今天一套友商安装的数据库使用adrci 查看日志提示No ADR base is set, 检查了$ORACLE_BASE环境变量也存在，同时也未使用symbolic links 目录，临时解决当然可以使用adrci中SET BASE ADR_BASE DIR手动指定ADR BASE, 对于使用频繁的工具，手动set，不能忍。

这个问题通常的原因是$ORACLE_HOME/log/diag 目录下的adrci_dir.mif 文件缺失或损坏、权限错误， 这个文件中指定了ADR base的目录。手动创建一下这个文件就可以解决，Note 不可以使用vi 创建，因为它会附加行尾换行符，可以使用printf command工具。

Troubleshooting ORA-15028 during drop archivelog failed in ASM

前几天朋友问无论使用asmcmd rm还是rman 在删除一个归档日志时，提示ora-15028 文件正在被访问，分析是O002进程占用，该进程是oracle instance修改asm instance metadata的进程， 经测试是非致命进程，可以尝试kill, 不必重启instance. 下面是诊断方法。

rman drop archivelog 或asmcmd> rm xxx时提示:

ora-15028 ASM FILE 'XXXXXXX' NOT DROPED, currently being accesed.

查看是哪个进程占用
使用asmcmd lsof只能看到是哪个实例在占用此文件，定位进程可以使用errorstack

Note: 是在ASM instance实例启用event

alter system set events '15028 trace name errorstack level 3';

也可以使用 systemstate dump，搜索文件名为关键字，也可以找到session 进程。

这里占用进程是O002进程。 之前的blog 写过Oracle 哪些进程可以KILL不会导致实例重启l 哪些是致命进程，判断Onnn进程是非致命进程。

经测试Onnn进程可以kill, kill后再有asm 元数据操作时如create tablespace in ASM ,Onnn进程会自动启动。kill 进程后就可以删除该文件，如果失败可尝试重启此实例。

Know more about PGA_AGGREGATE_LIMIT 12c 19c

July 14, 2021, 7:23 pm
$
0
0

Prior to 12c,PGA_AGGREGATE_TARGET was the Parameter used to control amount of memory allocated to User Processes(mainly work areas). However PGA_AGGREGATE_TARGET is a soft target and not a hard limit. The actual PGA usage can be as high as three times of the value of PGA_AGGREGATE_TARGET.This can lead to memory swapping & performance degradation.

In automatic PGA memory management mode, Oracle Database attempts to adhere to the PGA_AGGREGATE_TARGET value by dynamically controlling the amount of PGA memory allotted to work areas. However, PGA memory usage may exceed the PGA_AGGREGATE_TARGET setting at times due to the following reasons:

1.  The PGA_AGGREGATE_TARGET setting acts as a target, and not a limit. 
2. PGA_AGGREGATE_TARGET only controls allocations of tunable memory.

12c introduced new parameter PGA_AGGREGATE_LIMIT to allow database administrators to limit the aggregate pga memory usage.

The PGA_AGGREGATE_LIMIT initialization parameter enables you to specify a hard limit on PGA memory usage.  The background process CKPT checks every three seconds to see whether the amount of memory exceeds the value of the PGA_AGGREGATE_LIMIT initialization parameter.  If the PGA_AGGREGATE_LIMIT value is exceeded, Oracle Database aborts or terminates the sessions or processes that are consuming the most untunable PGA memory in the following order:

1.  Calls for sessions that are consuming the most untunable PGA memory are aborted. 
2.  If PGA memory usage is still over the PGA_AGGREGATE_LIMIT, then the sessions and processes that are consuming the most untunable PGA memory are terminated.

The sessions using the most untunable memory will have their calls aborted. Parallel queries will be treated as a unit. If the total PGA memory usage is still over the limit, then sessions using the most untunable memory will be terminated.

SYS processes and background processes other than job queue processes will not be subjected to any of the actions described in this section. Instead, if they are using the most untunable memory, they will periodically write a brief summary of their PGA usage to a trace file.

Untunable PGA memory is like context information for each session, for each open/active cursor, PL/SQL or Java memory.
Tunable PGA memory is memory allocated for intensive memory SQL operators like sorts, hash-join, group-by, bitmap merge and bitmap index create.

The PGA_AGGREGATE_LIMIT initialization parameter dynamically sets an instance-wide hard limit for PGA memory. a database restart is not necessary. Because the parameter responds to changing memory conditions, you do not need to set the parameter value explicitly. By default, PGA_AGGREGATE_LIMIT is set to:

In Oracle release 12.1:  the greater of the following:

1. 2 GB 
2. 200% of PGA_AGGREGATE_TARGET 
3. (Value of PROCESSES initialization parameter setting) * 3 MB

It will not exceed 120% of the physical memory size minus the total SGA size.

In Oracle release 12.2:

* If MEMORY_TARGET is set, then PGA_AGGREGATE_LIMIT defaults to the MEMORY_MAX_TARGET value.
* If MEMORY_TARGET is not set, then PGA_AGGREGATE_LIMIT defaults to 200% of PGA_AGGREGATE_TARGET.
* If MEMORY_TARGET is not set, and PGA_AGGREGATE_TARGET is explicitly set to 0, then the value of PGA_AGGREGATE_LIMIT is set to 90% of the physical memory size minus the total SGA size.

In all cases, the default PGA_AGGREGATE_LIMIT is at least 2GB and at least 3MB times the PROCESSES parameter.

In Oracle release 18c and above, it should be at least 5MB times the PROCESSES parameter for an Oracle RAC instance.

The MGA (Managed Global Area) is accounted for out of the PGA.
What this means in practical terms is that the PGA size must be increased in 18c and above versions to accommodate the MGA.

A rule of thumb is:

PGA_AGGREGATE_LIMIT = (original PGA_AGGREGATE_LIMIT value) + ((maximum number of connected processes) * 4M)

Another effect of this issue is that customers can report increased PGA usage after upgrading to 18c and above.
This is expected as the MGA is now accounted for out of the PGA.

NOTE: If a value of 0 is specified for PGA_AGGREGATE_LIMIT, it means there is no limit to the aggregate PGA memory consumed by the instance.

 

On 19c(19.7+), The value of PGA_AGGREGATE_LIMIT has some internal restrictions. For example, its upper limit is calculated from physical memory and the SGA usage. from db alert log will show that.

Also, its lower limit requires to be at least 3MB * processes parameter (or 5MB * processes if RAC).

If error during  upgrade using DBUA cause by PGA_AGGREGATE_LIMIT，like this:

ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT

The solution is to look at increasing the PGA_AGGREGATE_TARGET to a higher value & retry the Upgrade.

the wait event “Acknowledge Over PGA Limit” is a new wait event that was introduced with PGA_AGGREGATE_LIMIT in 12.1,  and it will force a process that wants more PGA to wait a bit if the instance is getting close to hitting the limit.

The solution you can set PGA_AGGREGATE_LIMIT = 0 for unlimited.

Troubleshooting: Oracle 19c wait event ‘latch: MGA shared context root latch’

最近一套客户环境从12C 升级19c(19.9)后在我们的监控上Wait class “Concurrency”等待告警进入TOP,  但是从V$SESSION和ASH view中的活动(active)的会话并未显示这么严重等待， AWR的top event中同样也不存在， 但是算在了Wait Classes by Total Wait Time和Background Wait Events里面，具体的wait event为“latch: MGA shared context root latch” , 1小时的AWR些latch wait 时间高达55,141秒，开始Oracle反馈这应该只是AWR数据计算错误，但其它相同版本环境并没有这么明显，监控页面天天“红”，又不是股市大盘，不能忍，所以想再继续探索一下。

主要还是latch: MGA shared context root latch, 对于这个latch 还是头一次见，对于Oracle我们都知道SGA, PGA, UGA, 但是MGA 以是什么东东？

什么是MGA？

对于MGA的资料并不是很多，首先是MOS上的MGA (Managed Global Area) Reference Note (Doc ID 2638904.1)，和在他的BLOG上介绍了一些， MGA是从12.1时先引入，在非XD环境中是从18c对外开放，但未在v$pgastat中显示具体值，从19c开始可以从v$pgastat 视图查看MGA大小。MGA的目的是优化共享内存， MGA 允许“较小的一组”进程（甚至所有进程）在持续时间内（通常是查询）共享地址空间(namespace)。MGA 由包含segment和heap(KGH)的namespace组成，MOS上举例如:

Processes can attach to their namespace for the duration they require.  For e.g., in a parallel query environment, PQs participating with the QC can share the namespace from QC to share the results.  Once done, they will detach from the same and the namespace can be tiered down.

MGA又不同于SGA和PGA，他是弹性按需创建，进程可以动态的创建和删除MGA segment，同时又可以在部分和全部进程间共享。大小是计入PGA(v$pgastat)，又独立于PGA,  同时也受PGA的限制(PGA_AGGREGATE_LIMIT), 所以在升级19c（18c）后需要增加额外的PGA大小，上一篇笔记关于PGA_AGGREGATE_LIMIT中有记录.

因为MGA是共享内存区，所以需要使用latch: MGA 来控制访问和保护。相关的几个event：

Note:

当前看主要发生在shared context root latch 上，也可能root latch就单个，所以争用较为集中，如发生成进程初始化阶段，后期版本有可能增加并行，从where的2个函数猜测 ksm_mga_detach_whr1应该是在session logout, 那ksm_mga_attach_whr1 应该是session logon.  那就有可能是连接风暴导致，看一下登录

Note:
当前这个库的会话数较高约达17k， 同时每秒连接LOGON为40也不低， 目前也就这两个指标相比其它同版本环境较高，且只有这个节点问题较为突出， 判断与较高的短连接有关，我们在其它环境初始化了15K会话数，再以40每秒的短连接测试，也可以测试出latch: MGA shared context root latch 快速增加，但未能模拟出像生产相同的现象。
