AIX6.1 Oracle 10.2.0.5 patch installation error Solution

An Oracle database of 10.2.0.1 is installed on aix6.1. If you want to enter 10.2.0.5pathc, an error is returned. The specific error was forgotten at the time. It probably means that the system process of some prompts will be ended. Later, I checked oracle support and found an article to explain how to solve the problem. Article No. [ID 975597.1]

The solution provided by oracle is as follows:

Solution
To implement the solution, please execute the following steps:

1. Exit the current installer

2. As root user:

Cd/usr/sbin/
Mv fuser. orig
Touch/usr/sbin/fuser
Chmod + x/usr/sbin/fuser

3. As oracle software owner, install the 10.1.2.3 patchset.
(Note: fuser can now return nothing, hence the Installer shocould continue)

4. After a successful installation, as the root user, rename the fuser back.

Cd/usr/sbin/
Cp fuser. orig fuser
