Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: No informational message is issued * * informing a customer site that an SVC * * dump will be suppressed if a dump * * already exists with the same program * * name, CICS abend code, system abend * * code, and abend program offset. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes and MASes must be * * restarted. Note that the restarts do not * * need to occur at the same time. * **************************************************************** XZPT (EYU0XZPT - External Services Trace Method) and XLRV (EYU9XLRV - Environment Error Recovery Program) will determine if a dump is to be suppressed, based upon the number of times the dump has been taken, but logic does not exist to issue a message informing the site that it is being suppressed.
Problem conclusion
SVC dump processing has changed. CMAS and MAS dumps are separated in the abend control table of entries. At most two entries exist in the table. One for the CMAS, and one for all MASes that are connected to it. Each entry contains a count of the number of times the abend has occurred. During a CPSM CMAS cold start (all MASes are down that were connected to the CMAS prior to the CMAS being restarted) all table entries are reset. During a CPSM CMAS warm start (at least one MAS is active that was connected to the CMAS prior to the CMAS being restarted), the count will be reset to zero for CMAS related abend entries. The count will be reset to zero for MAS related abend entries when no MASes are connected to the CMAS. SVC dump suppression is controlled by the ESDUMPLIMIT CICSPlex SM system parameter, only if the ESDUMP system parameter is set to NO. It can be used in the startup job of a CMAS and controls the number of dumps collected for a given failure. The default value is 1. Dump suppression occurs for duplicate dumps once this threshold has been reached. Valid values are 0 to 999. Added new field XLAE_ABEND_TYPE to the EYURXLAB (Kernel Linkage Abend Block). This field will indicate whether the execution environment is a CMAS or LMAS. Added new field RECV_ABEND_TYPE to the EYURXLRW (Kernel Linkage Recovery Work Area (RECV) mapping DSECT). This field will indicate whether the execution environment is a CMAS or LMAS. Updated EYU0XZPT so that when a dump is being suppressed because the SVC dump limit has been reached new message EYUXZ0912W will be issued: EYUXZ0912W EYU0XZPT dump suppressed because ESDUMPLIMIT has been reached Updated EYU9XLRV so that when a dump is being suppressed because the SVC dump limit has been reached new message EYUXL0912W will be issued: EYUXL0912W EYU9XLRV dump suppressed because ESDUMPLIMIT has been reached CLET (EYU0CLET - COMM LPROT ESSS Initial Contact Transient) service requests consist of two functions: ATTACH and DETACH ESSS logical connection. A count field has been added to CLET to track the ATTACH/DETACH processing. The XLAE_ABEND_COUNT field indicates how many times an abend has occurred for a given failure. It will be reset to zero for MAS related abends when no MASes are connected to the CMAS. Updated XDIN (EYU0XDIN - Data Repository Initialization) to scan the elements of the EYURXLAB if it already exists and reset the XLAE_ABEND_COUNT field to zero if the entry is for a CMAS. Recompiled EYU9XLRW (Environment Error Recovery Program WTO Messages) to pick up the updated control blocks. Added message EYUXZ0912W to EYUTXZM0 (Trace Services Message Prototype Table) and to EYUUXZEQ (Trace Services Standard Equates).
