In earlier releases of CICS®, you have to make two separate inquiries to find out which plan is used by a specified transaction or set of transactions. This is because the transaction ID is part of the DB2TRAN definition, but the plan name or plan exit name is part of the DB2ENTRY definition. Enhancements to the INQUIRE DB2TRAN command mean you can now use a single INQUIRE DB2TRAN command to find out which plan is used by a specified transaction or set of transactions, or which transactions use a specified plan (see Changed CEMT commands and The system programming interface (SPI) for details of the changes to the commands).
Note that there is still a restriction on finding information for individual transaction IDs if a DB2TRAN is defined with a wildcard character in the TRANSID. See the CICS Resource Definition Guide for information.
