Re: running different version of IDS 9.x

Yes. In the environment files for the 9.21 startup and any 9.21 shared memory clients set LD_LIBRARY_PATH to point to $INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$INFORMIXDIR/lib/tools before /usr/lib so that the older libs are always picked up first. You can do the same while your setting up the scripts for the 9.30 instances and clients so next upgrade (perhaps to 9.40 next year?) will be all set. We don't access Informix libraries out of /usr/lib at all only from $INFORMIXDIR/lib/* just because the upgrades are painless that way. Art S.
