11.2.0.4 打patch遭遇extjobO: Operation not permitted处理

发表于 2021 年 4 月 16 日 由 惜分飞

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
make: [iextjob] Error 1 (ignored)

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

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The contents of "dbhome" have not changed. No need to overwrite.

[root@localhost home]# ls -l  /u01/app/oracle/product/11.2.0/db_1/bin/extjob*
-rwsr-x--- 1 root   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

确实通过执行root.sh修复该问题.

今天对主库进行打了psu和ojvm成功之后，对standby库打上了psu和ojvm，然后给备库启动mrp进程发现余下报错

由于redo中有migration操作,导致备库mrp应用进程失败,解决此类问题最简单的方法,就是把备库重启到mount状态,然后使用rman进行恢复操作,然后再继续open库,启动mrp解决这类问题

记录一次oracle现场故障处理经过

发表于 2021 年 4 月 3 日 由 惜分飞

近期到现场进行了一个数据库恢复,我在恢复之前该库先由于硬件进行恢复,然后由其他人对其进行了一系列数据库恢复,但是未恢复成功,客户希望我们到现场进行处理(因为网络原因无法远程).接手库之后,处理第一个问题,是客户在进行现场备份的时候(把linux数据拷贝到win的过程中)发现有几个文件拷贝异常,这个错误很可能是由于当初的硬件故障修复之后留下的后遗症(由于io设备错误,无法运行此项请求),通过工具进行拷贝,恢复出来

初步判断是由于对方之前恢复导致部分文件resetlogs scn异常,通过bbed进行判断确认

BBED> set file 1
        FILE#           1

BBED> p kcvfhrls

   ub2 kscnwrp                              @120      0x0000

通过bbed修改相关值,然后重建控制文件成功,尝试resetlogs库，报ORA-01248错误

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01248: file 234 was created in the future of incomplete recovery
ORA-01110: data file 234: '/oradata1/xifenfeidata5.DBF'

关于ORA-01248的错误解释

01248, 00000, "file %s was created in the future of incomplete recovery"
// *Cause:  Attempting to do a RESETLOGS open with a file entry in the
//          control file that was originally created after the UNTIL time 
//          of the incomplete recovery.
//          Allowing such an entry may hide the version of the file that 
//          is needed at this time.  The file number may be in use for 
//          a different file which would be lost if the RESETLOGS was allowed.
// *Action: If more recovery is desired then apply redo until the creation
//          time of the file is reached. If the file is not wanted and the
//          same file number is not in use at the stop time of the recovery,
//          then the file can be taken offline with the FOR DROP option.
//          Otherwise a different control file is needed to allow the RESETLOGS.
//          Another backup can be restored and recovered, or a control file can
//          be created via CREATE CONTROLFILE.

大概的意思是文件的创建时间大于文件当前的scn,通过查询确实如此

通过对部分scn进行修改（比如减小创建时间的scn)，然后尝试resetlogs库

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

这个错误比较简单,参考以前的部分文章:在数据库open过程中常遇到ORA-01555汇总数据库open过程遭遇ORA-1555对应sql语句补充,处理之后,数据库open成功

本次数据库恢复基本上完成,已经最大限度恢复数据,导出数据到新库,完成恢复任务
