Error description
If a CPSM TSSJ transaction is running to join a MAS to a CMAS and a disconnect for the same MAS comes in at the same time, CPSM will attempt to purge the TSSJ transaction and issue an EYUTS0025I message: . EYUTS0025I Topology Join for xxxxx terminated due to Disconnect request - APPLID(xxxxx) CICSplex(yyyyyyy). . If CICS is not able to purge the TSSJ immediately, the abend may be deferred. . At the same time, an AFCY abend is produced, and CPSM requests an SVC dump. In this instance, the dump is not necessary for diagnostic purposes, and can be suppressed. This APAR is being submitted to add additional checking and suppress the unnecessary dump. . Note that the same situation may occur if a MAS is connecting to a CMAS. In that case, the transaction would be TSSC. . Additional symptoms: TITLE=EYU9XLRV CSJOINE TISTTSSJ GETAREC HDR1READ PK59481 UK33294 . KIXREVSVR

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V4R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: If a MAS is terminated while a Topology * * Connect or Join request is active, the * * request is terminated and message * * EYUTS0025I is issued. Depending upon * * where the Connect or Join process is at * * the time of termination, an AFCY abend * * may also occur. * * * * If the AFCY occurs, CPSM produces abend * * information messages and may request a * * dump. Neither are required for * * diagnostic purposes as the EYUTS0025I * * indicates why the Connect or Join was * * terminated. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes must be restarted. Note * * that the restarts do not need to occur at * * the same time. * **************************************************************** When a disconnect request is received for a MAS while it is in the process of connecting or joining to a CMAS, method EYU0TSST (TSST) calls method EYU0XLTP (XLTP) to terminate the connect task (transaction TSSC) or join task (transaction TSSJ). If the TSSC or TSSJ task is in a wait, then XLTP will post the termination ECB and only the EYUTS0025I will be returned. If the TSSC or TSSJ task is performing data repository I/O, then XLTP will issue a EXEC CICS SET TASK FORCEPURGE request. This will drive CPSM abend recovery, where module EYU9XLRW will issue the EYUXL09nns abend informational messages, and module EYU9XLRV will request a dump.
Problem conclusion
Updates have been made to suppress the abend informational messages and the dump if a TSSC or TSSJ task is forcepurged because the MAS being connected or joined has terminated. - TSST will pass a new parameter when calling XLTP. - if the new parameter has been specified, and a force purge is required, XLTP will turn on a new flag in the object process block (OPB) of the task to be terminated. - when called for abend recovery, EYU9XLRV will check if the new OPB flag is on for the abending task. If so, EYU9XLRV will bypass the call to EYU9XLRW, thus suppressing the abend informational messages, and will not request a dump.
