When I call oninit -i command in an Ubuntu server terminal, it shows an error like this:
INFORMIXSERVER does not match DBSERVERNAME or any of the DBSERVERALIASES.FAILED
Can anyone give me a solution for this problem?
What is the setting of $INFORMIXSERVER in your environment, and what values are set for DBSERVERNAME and DBSERVERALIASES in the $ONCONFIG file? It seems that you've set $INFORMIXSERVER to a value that isn't present in the $ONCONFIG file that is in use. Maybe you didn't set $ONCONFIG at all, or maybe you set $INFORMIXSERVER incorrectly, or maybe the names in the $ONCONFIG file are incorrect.
If you don't set $ONCONFIG, it defaults to onconfig (and maybe even falls back to onconfig.std). But you should normally set $ONCONFIG to a known value. I usually use onconfig.<servername> where the <servername> is the value of DBSERVERNAME in the file. However, nothing enforces that convention.
