Oracle10g Bug 4612267 补丁安装备忘录

一、bug症状和描述

症状：
当主机运行时间达198天或248天，cpu占用率就突然达到100%。此时操作系统命令可以执行，但Oracle的命令象lsnrctl、sqlplus、dbca等都会被hang住，不能执行。

Oracle官方对该bug的描述：
#-------------------------------------------------------------------------
# Interim Patch for Base Bugs: 4612267 
#-------------------------------------------------------------------------
#
# DATE: Wed Oct 5 10:17:13 2005
# -------------------------------
# Platform Patch for : Linux x86
# Product Version # : 10.2.0.1
# Product Patched    : ORACORE
#
# Bugs Fixed by this patch:
# -------------------------
# 4612267:OCI CLIENT IS IN AN INFINITE LOOP WHEN MACHINE UPTIME HITS 248 DAYS
#-------------------------------------------------------------------------

备注：
事实上只要Linux x86主机运行天数是是24.8的倍数都有可能引发该bug，因为time()函数值为null，造成无限死循环，从而耗尽cpu。

解决办法三种：
1) 重启主机；
2) 打patch set，如升级到10.2.0.4；
3) 对该bug单独打临时patch 4612267。
第一种方法没有彻底解决问题，以后照旧；第二种方法，升级时间长，且要求停库很久，当前生产环境暂不适合；本文采用第三种方法。

Doc ID: 338461.1 SQL*Plus 10.2.0.1 Hangs, When System Uptime Is Long Period of Time
Doc ID: 4612267.8 Bug 4612267 - OCI client spins when machine uptime >= 249 days

二、先停监听、dbconsole和数据库

$ lsnrctl stop
$ emctl stop dbconsole
$ sqlplus / as sysdba
SQL> shutdown immediate

注意：dbconsole是在已经装了Oracle EM的情况下要停止，如果未安装则无需干涉。

三、安装patch

$ mkdir $ORACLE_BASE/patches
$ cd $ORACLE_BASE/patches
$ rz    (SecureCRT里上传 p4612267_10201_LINUX.zip 文件, 其它上传方式也可以)
$ unzip p4612267_10201_LINUX.zip   
$ cd 4612267/
$ $ORACLE_HOME/OPatch/opatch apply
Invoking OPatch 10.2.0.1.0
...
Please shutdown Oracle instances running out of this ORACLE_HOME on the local system.
(Oracle Home = '/u01/app/oracle/product/10.2.0/db_1')

Is the local system ready for patching?

Do you want to proceed? [y|n]
y    (此处输入y)
User Responded with: Y
...
ApplySession adding interim patch '4612267' to inventory

The local system has been patched and can be restarted.

OPatch succeeded.

四、验证patch

$ $ORACLE_HOME/OPatch/opatch lsinventory
Invoking OPatch 10.2.0.1.0

--------------------------------------------------------------------------------

OPatch succeeded.

五、启动数据库、监听和dbconsole

$ sqlplus / as sysdba
SQL> startup
$ lsnrctl start
$ emctl start dbconsole

六、如果有需要，还可以删除patch，删除前先停库

$ cd $ORACLE_BASE/patches/4612267
$ $ORACLE_HOME/OPatch/opatch rollback -id 4612267
Invoking OPatch 10.2.0.1.0
...
Please shutdown Oracle instances running out of this ORACLE_HOME on the local system.
(Oracle Home = '/u01/app/oracle/product/10.2.0/db_1')

Is the local system ready for patching?

Do you want to proceed? [y|n]
y    (此处输入y)
User Responded with: Y
...
RollbackSession removing interim patch '4612267' from inventory

The local system has been patched and can be restarted.

OPatch succeeded.

此时再执行上面的验证patch命令就会发现该patch已经删除了。
