Checks on definitions of Db2® connection resources

When you define a DB2CONN, CICS® checks for consistency with other resource definitions in the same group or list.

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.
