Description :After doing a network change on the infrastructure the dollar universe node does not start anymore.
When launching the script uxstartup we get no output:
Example:
###############
root@frstaix716:/******/*****/mgr#./uxstartup
UNIVERSE startup procedure beginning
UNIVERSE startup procedure beginning
Nodes = ******
Companies = *****
End of UNIVERSE startup procedure
###############
Environment:
OS: All Unix
Cause:
Cause type:
Configuration
Root Cause: The error at startup comes from the fact that the hostname of the local node is not correctly resolved on the system.
Resolution:
In order to fix the problem there are two possibilities:
1. Configure properly on the DNS or /etc/hosts file the correct mapping of hostname / ip adress of your system
2. Edit the file $UXMGR/uxsrsrv.sck and replace on the line containing your impacted node the second column which maps to the hostname and put the local ip adress of the server instead of the hostname.
