Removing DB2INSTDEF value from registry

Database: DB2 v9.5 on AIX

Scenar开发者_开发问答io: I have 2 instances- db2inst1 and db2inst2. I created db2inst1 first. I went ahead and created db2inst2 next and I do 'db2set -all' on db2inst2 instance I see this:

[g] DB2INSTDEF=db2inst1

I would like to reset DB2INSTDEF and make it not show up when I do 'db2set -all' (other than dropping and recreating db2inst1).

Thanks.

DB2INSTDEF does not apply on AIX (it's only used on Windows systems), so it doesn't really matter if (or what) it is set to. Why is this a problem?

If you really want to eliminate the variable, then run (as root):

/opt/IBM/db2/V9.5/adm/db2set -g DB2INSTDEF=

(The path /opt/IBM/db2/V9.5 may be slightly different on your system, depending on whether you installed DB2 into the default location or not).
