Error description
The "DISTILL" option is added to DUMPLOAD which will create an abridged CP dump on CMS space from a dump on spool space. Some dumps that CP creates include large structures (frame table and/or pageable PGMBKs) to aid diagnosis of memory management problems. A new "DISTILL" option on DUMPLOAD extracts an abridged dump omitting these structures from a hard abend dump or snapdump on spool. This smaller dump is easier to manage and faster to transmit to IBM, allowing diagnosis to begin sooner. The complete dump remains in spool and can be loaded and sent later if needed.

Problem summary
**************************************************************** * USERS AFFECTED: All users that process z/VM CP dumps * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** This Apar adds the DISTILL option to the DUMPLOAD utility and it can be used to create an abridged dump. The abridged dump will contain a correlation table instead of the CP frame table and most page management blocks (PGMBKs) will be omitted. You can then submit this abridged dump to IBM customer support for diagnosis. This alleviates the problems and delays that can occur when you try to submit a very large hard abend dump or snap dump to IBM. The reduction in size of an abridged dump distilled from a dump taken using, for example, the SET DUMP FRMTBL YES PGMBKS ALL command, can be as much as 95%. The original dump remains available as a spool file and can be loaded into a CMS file for transmission to IBM later, if necessary. The documentation for the DUMPLOAD CP utility has been updated. Also, the following CP messages are new: HCP8186I, HCP8187I, and HCP8188I.
