NAME - Naming the Module to Change Through the JES2 Patching Facility z/OS JES2 Initialization and Tuning Reference SA32-0992-00 |
|
The NAME initialization statement is one of several statements used by the JES2 patching facility. For the other statements, see REP - Replacing Code Through the JES2 Patching Facility and VERify - Verifying Code Through the JES2 Patching Facility. When specifying replacement data, this statement is optional unless JES2 issues a $HASP467 message indicating that data cannot be replaced at the storage location specified. If JES2 issues a $HASP467 diagnostic message, you must use the NAME statement before specifying the VER and REP statements. The JES2 patching facility allows you to specify replacement data (patches)
for the following:
The JES2 patching facility applies temporary patches to the in-storage
copy of JES2 modules. You place patching facility statements in the JES2
initialization stream; these patches are applied when you initialize JES2.
Because some of the initialization code has already been executed before
the patch facility initialization statements are processed, patches made to
those portions of the code are ineffective; those portions of code do not execute again until you restart JES2. Most patches are applied
immediately as the statements are processed. However, checkpoint updates
are deferred until the checkpoint record is read. Non-checkpoint patches
are not saved across a warm start. In addition, you should be aware that
the JES2 patching facility does not support:
The JES2 patching facility statements in the JES2 initialization data set can be specified in either the JES2 patching format or in the AMASPZAP format. All patches in the JES2 patching form should precede any AMASPZAP patches. If you supply the NAME statement or first format type of the AMASPZAP patch, JES2 resets prior verification errors. For more information on AMASPZAP patches, see "SPZAP" in z/OS MVS Diagnosis: Tools and Service Aids. |
