For a DB2CONN object, the following checks are made:
- To ensure that there is only one DB2CONN defined in the group or list.
If more than one is found (even one with a different name), a warning message
is issued. Only one DB2CONN can be installed at a time.
- That PLANEXITNAME exists as a program definition in the group or list
if a PLANEXITNAME is specified, and program autoinstall is not active.
