RELEASE

Release a loaded program, table, or mapset.


RELEASE

>>-RELEASE--PROGRAM(name)--------------------------------------><

Conditions: INVREQ, NOTAUTH, PGMIDERR

This command is threadsafe.

Note for dynamic transaction routing: Using RELEASE of a program LOADed with HOLD could create inter-transaction affinities that adversely affect the use of dynamic transaction routing. See Affinity for more information about transaction affinities.

Description

RELEASE releases the program, table, or mapset previously loaded by a LOAD command. This means that the issuing task can no longer use the resource unless another LOAD is issued.

Note: RELEASE does not remove a program from storage. It reduces the RESCOUNT by 1 and when the count reaches zero, the storage occupied by the program can be released by CICS storage manager.

If the HOLD option is specified in the LOAD command, the loaded resource is not released at the end of the task. It can only be released by a RELEASE command. This RELEASE command may be issued by the task that loaded the resource or by any other task.

If the HOLD option is not specified in the LOAD command, the loaded resource is released at the end of the task. It may, however, be released before this by the task that loaded the resource issuing a RELEASE command.

Options

PROGRAM(name): specifies the identifier (1–8 characters) of a program, table, or mapset to be released.

Conditions

16 INVREQ

RESP2 values:

5: An invalid attempt is made by the program to release itself. A RELEASE command for the program that contains this command is allowed only when a corresponding LOAD command for the program has been issued from the same task, or when a LOAD command with the HOLD option has been issued from another task.
6: The command is issued for a program that is not loaded.
7: Either the command is issued for a program that was loaded, without the HOLD option, by another task; or the program has been enabled as a global user exit .
17: The program is defined with RELOAD=YES. It must be released by a FREEMAIN rather than a RELEASE command.
30: The program manager domain has not yet been initialized. This is probably due to a release request having been made in a first stage PLT.

Default action: terminate the task abnormally.

70 NOTAUTH

occurs when a resource security check has failed on PROGRAM(name).

Default action: terminate the task abnormally.

27 PGMIDERR

RESP2 values:

1: A program, table, or mapset has no installed resource definition.
2: A program, table, or mapset is disabled.
9: The installed program definition is for a remote program.
42: An attempt has been made to RELEASE a JVM program. This is invalid because Java™ byte codes programs are not managed by CICS Loader.

Default action: terminate the task abnormally.

Examples

The following example shows how to release an application program, called PROG4, loaded in response to a LOAD command:

EXEC CICS RELEASE PROGRAM('PROG4')
