This section describes the guidelines for installing and discarding
DB2TRAN definitions and the implications of interruptions in partial activity.
- You cannot install more than one DB2TRAN for the same transaction, if
you have given the full transaction ID in the DB2TRAN definition. If you have
used a generic transaction ID with a wildcard character, you can install more
than one DB2TRAN that potentially matches the transaction, but CICS® only uses the
closest match (see Wildcard characters for transaction IDs).
- A DB2TRAN that refers to a non-existent DB2ENTRY cannot be installed.
The DB2ENTRY must be installed first.
- Note that when DB2ENTRY and DB2TRAN definitions are defined in the same
group, CICS installs the DB2ENTRY first at install time.
- You can install a new DB2®TRAN at any time, even when the CICS DB2 adapter is
connected to DB2.
- A DB2TRAN can be re-installed at any time, and can be discarded at any
time.
