Error Message :
N/A

When Dollar Universe is started with non-root user, we note that the performance of the product is impacted.

This can be observed especially when launching the Command Line commands inside or outside the Uproc script.

The sessions launched simultaneously would take more time on version 6 than on version 5.
Environment:
OS: All Linux/Unix
OS Version: The issue is specially important on AIX systems
Cause:
Cause type:
Defect
Root Cause: Some security checks introduced on version 6 would impact the performances of Dollar Universe when the product is started via a non root user
Resolution:
Update to a fix version listed below or a newer version if available.

The performances of the Dollar Universe started as a non-root user should be equivalent to the root ones.

Fix Status: Released

Fix Version(s):
Component(s): Application.Server

Dollar Universe 6.8.21 - Available
Additional Information:
Workaround :
Assign the Dollar Universe node to be started as root.
To do so, login as root and launch the following commands:


. ./unienv.ksh
$UNI_DIR_EXEC/unistop
$UNI_DIR_EXEC/uxrights -m assign -a root
$UNI_DIR_EXEC/unistart


IMPORTANT:
After this modification is performed, the Maintenance session and some other jobs will need to be launched as root instead of the previous user, else they will fail.
Also, Stop / Start of the Node will only be able to be performed as root.
