Information about the system programming function provided by CEMT for the following commands can be seen in CICS® Supplied Transactions:
Information about the EXEC CICS INQUIRE and EXEC CICS SET commands is in the CICS System Programming Reference.
PLAN and PLANEXITNAME options are available on the INQUIRE DB2TRAN command, so you can find out in a single step which plan is used by a specified transaction or set of transactions, or which transactions use a specified plan.
The DSNC transaction can be used to perform the following:
The DSNC transaction executes program DFHD2CM1, which handles both CICS DB2 attachment facility and DB2 commands. You can distinguish DB2 commands from CICS DB2 attachment facility commands by the hyphen (-) character, which is entered with DB2 commands. This character is not a DB2 subsystem recognition character, but a command recognition character. It is always a -, independent of the character actually defining the DB2 subsystem, since CICS can only connect to one DB2 subsystem at a time. There is no need to use different DB2 subsystem recognition characters from CICS, and thus we use only the default - character.
DFHD2CM1 can also be activated by transactions other than DSNC. Thus you can give a different transaction code to each CICS DB2 attachment facility command, and to each DB2 command. This enables you to apply different levels of security to each command.Alternative transaction definitions for CICS DB2 attachment facility commands are supplied in sample group DFH$DB2, using the following names:
Alternative transaction definitions for DB2 commands are also supplied in sample group DFH$DB2, using the following names:
-ALT | -CAN | -ARC |
-DIS | -MOD | -REC |
-RES | -SET | -STA |
-STO | -TER |
