当在aix6.1 TL04下安装oracle10补丁时，出现java进程正在被使用的报错，安装无法继续进行。报错信息如下：

INFO: Oracle Universal Installer has detected that there are processes running in the currently selected Oracle Home. The following processes need to be shutdown before continuing:
java

查看操作系统的java进程，发现只有Oracle patch安装进程使用了java ，OUI安装程序做了错误的检测。

3          处理过程

3.1      查询资料

查询metalink文档980602.1 ，明确这是ORACLE BUG:9227281

Oracle Universal Installer - Version: 10.2.0.2.0 to 11.1.0.7 - Release: 10.2 to 11.1
IBM AIX on POWER Systems (64-bit)

Installing patchset on AIX 6.1 TL04 fails with:

INFO: Oracle Universal Installer has detected that there are processes running in the currently selected Oracle Home. The following processes need to be shutdown before continuing:
java

The java process running is the Installer itselt.

This problem has been reproduced installing 10.2.0.4 and 11.1.0.7 patchset, but it could affect to other patchsets.

This seems a IBM issue at the fuser coming with AIX 6.1 ML4 SP1.

Two Oracle bugs were created to investigate this issue:

Bug.9227281 - OUI 10.2.0.4 DETECTS JAVA PROCESS RUNNING ON ORACLE_HOME AIX 610
Unpublished Bug.9228329 - 11.1.0.7 OUI FAILS TO DETECT RUNNING PROCESSES CORRECTLY ON AIX 6.1 ML 4 SP1

3.2      解决方法

IBM has released AIX patch to solve the issue:
               IZ67400: FUSER GIVES INCORRECT PIDS WITH -X OPTION

Registration is required to review patch IZ67400 on IBM web site.

Also, next workaround could be used:

As root:
1) rename fuser  
   mv /usr/sbin/fuser /usr/sbin/fuser_renamed
2) touch /usr/sbin/fuser
3) chmod +x /usr/sbin/fuser

As oracle software owner:
1) Try to install the patchset (fuser can now return nothing, hence the Installer should continue)

After successful install, as root:
1) rename fuser back to its original name
  mv /usr/sbin/fuser_renamed /usr/sbin/fuser

4          总结

这是Oracle与AIX6.1之间的又一个较严重的兼容性问题，AIX6100-04-04-1014已解决。解决这个问题有两个方案：

1.      升级AIX到6100-04-04-1014以上版本

2.      临时解决方案，把fuser命令改名，安装完patch后再恢复
