Environment

Data Protector Version on the Cell Manager and the Client-server: 10.90
Cell Manager: gpl x86_64 linux-3.10.0-1160.el7.x86_64
Client: ibm rs6000 aix-7.2

Situation

The backup is completed successfully with no error but unable to browse an oracle instance during restoration on different AIX servers, the following error appears:
 

"[12:1604] cannot reach the CRS on the Cell Manager system. 
CRS on the cell Manager host is not reachable or is not up and running".

Cause

The root cause is a binary packaging problem, and INET executes the 32-bit version of util_orarest.exe instead of the 64-bit version

Resolution

Navigate to the "/usr/omni/lbin" folder on the AIX client-server and try the following:

1. Rename util_orarest.exe to util_orarest32.exe 

2. Rename util_orarest64.exe to util_orarest.exe
