RE: Ontape restore to another server
Posted in 2006
I think the idea will work. I have to look at some of my systems and
remember some things.
I am glad you said you would try this on your DEV box. Is the name of
your DEV database different than your PRD database? And what is the
name of your $INFORMIXDIR?
I believe you pegged the right onconfig params that need to be changed.
Let me put some more thought into it, check my systems, and post back.
Of course, once we plan this out, you may still want a warm/fuzzy with
IBM Informix tech support. I have done interesting things with my
systems, but I will only put my neck on the line, not yours ;)

This instance idea with a mounted file system sounds like a solution.
I did use links for my raw devices so that should not be an issue. My
dev box is also Solaris but has no space for the restore but the
mounted system from Linux can solve that.
Getting back to the tape drive which is unique on the production box.
If I add an instance on my dev box to use the production tape, is it
full proof that when I issue the ontape -r on the dev box that the
restore will be done locally and not on production? I don't want the
restore stepping on the prod box.
Question for instances. I have never configured one. I would copy the
onconfig to another name and change the DBSERVERNAME, DBSERVERALIASES,
MSGPATH, SERVERNUM & ROOTHPATH. I can keep my current INFORMIXDIR
right? Or do I need to make a complete copy else where? I should just
need to change ONCONFIG & INFORMIXSERVER?
