标题：11.2.0.4 打patch遭遇extjobO: Operation not permitted处理

有一段时间没有给11.2.0.4打psu补丁了,今天晚上在给一个客户打的过程中发现类似错误

OPatch found the word "error" in the stderr of the make command.
Please look at this stderr. You can re-run this make command.
Stderr output:
chmod: changing permissions of `/u01/app/oracle/product/11.2.0/db_1/bin/extjobO': Operation not permitted

对比extjob权限信息

[oracle@localhost trace]$ ls -l /u01/app/oracle/product/11.2.0/db_1/bin/extjob*
-rwxr-xr-x 1 oracle oinstall 1254496 Apr 16 23:15 /u01/app/oracle/product/11.2.0/db_1/bin/extjob
-rwx------ 1 oracle oinstall 1254496 Apr 16 23:15 /u01/app/oracle/product/11.2.0/db_1/bin/extjobo
-rwsr-x--- 1 root   oinstall 1254244 Feb 13  2019 /u01/app/oracle/product/11.2.0/db_1/bin/extjobO
-rw------- 1 oracle oinstall 1254244 Feb 13  2019 /u01/app/oracle/product/11.2.0/db_1/bin/extjoboO

证明新的extjob程序确实权限不对,不过根据官方的建议可以忽略这个,参考link:

https://updates.oracle.com/Orion/Services/download?type=readme&aru=20775452

Applying Proactive Bundle / PSU Patch fails with Error: “chmod: changing permissions of `$ORACLE_HOME/bin/extjobO’: Operation not permitted” (Doc ID 2265726.1)
给出来的理由是执行root.sh之后权限会变成正常的,另外这个external jobs基本上很少人会使用到,尝试执行root.sh修复

[root@localhost home]# /u01/app/oracle/product/11.2.0/db_1/root.sh
Performing root user operation for Oracle 11g 

The following environment variables are set as:
    ORACLE_OWNER= oracle

-rw------- 1 oracle oinstall 1254244 Feb 13  2019 /u01/app/oracle/product/11.2.0/db_1/bin/extjoboO

确实通过执行root.sh修复该问题.

有朋友和我反馈,说他们在装linux 6.5上面装11.2.0.3的rac出现异常，root.sh在第一个节点执行就失败了,请求帮助

这里可以看出来,asm实例无法登陆(ORA-01012和ORA-03113),根据这样的错误，分析asm日志

进一步分析asm日志，发现是大家熟悉的asm的ORA-4031问题,那就是说明数据库在执行root.sh的时候使用默认参数文件启动asm的时候shared pool不够大(根据ORACLE最佳实践，建议memory_target=1536M及其以上值)，从而出现该问题。类似Bug 14292825 ORA-4031 in ASM as default memory parameters values for 11.2 ASM instances low，根据官方描述该问题在11.2.0.4中修复
