Case study of Oracle 10g installation in AIX 5.3 -- ruInstaller

System Environment:

Operating System: AIX5300-08

Oracle software: Oracle 10g (64-bit)

Installing Oracle 11g R2 Based on IBM AIX

Add data files (bare devices) to the tablespace in AIX)

AIX6.1 install Oracle 11g R2

Install Oracle 10201 on AIX

AIX + HACMP + Oracle dual-host cluster project

Failed to start GSD on local node appears when Oracle 9i RAC is installed on AIX.

Error:

The customer has installed Oracle on an AIX host, uninstalled the Oracle software, changed the UID of the Oracle user, and re-installed Oracle with the following error:

View File System permissions:

[Root @ aix203/] # ls-l/u01/app/

Total 16

Drwxrwx --- 6 oracle oinstall 512 May 19 oracle

There should be no problem with file system permissions. Delete the Oracle user again and modify the/u01 file permissions again. The fault persists!

Solution:

1. umount/u01 file system first

[04:02:00 root @ aix203/] # mount

Node mounted over vfs date options
