Error description
When starting a target region prior to the RS data table server being started, the region does not automatically connect to the RS server as it does for routing regions. Every 15 seconds the MAS heart-beat processing is driven. As part of this processing, WNHD calls DFHRSSR to test the connection to the RS Server. If the server is not yet available, the following message is issued: . DFHFC7085 applid On a request to process OPEN for coupling facility data table CPSMPLEX for file DFHRSTAT, it has been found that the server for coupling facility data table pool DFHRSTAT, is down. The server should be restarted. . In the MAS log file this message is only issued once, on the first attempt to connect to the RS server. The MAS heartbeat processing is running but the check to test the connection to the RS Server is not being issued. . . . Additional Keyword(s) and Symptom(s): KIXREVGJT
Local fix
Ensure the RS Server is up and running before starting the target regions
Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V5R1M0 and V5R2M0 Users * **************************************************************** * PROBLEM DESCRIPTION: When a CPSM WLM target region that is * * defined as being enabled for * * optimization is started before the * * Region Status (RS) server becomes * * available, the following message is * * issued in the region's Job log: * * * * DFHFC7085 applid * * On a request to process OPEN for * * coupling facility data table dddd * * for file ffff, it has been found * * that the server for coupling * * facility data table pool poolname, * * is down. The server should be * * restarted. * * * * However, the region does not attempt to * * reconnect to the RS server as CPSM WLM * * routing regions will do every 15 * * seconds. As a result, when the RS * * server is available, the target region * * will not automatically connect to it. * * Instead, it will have to be restarted * * in order to become enabled for * * optimization. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all MASes defined as CPSM WLM target * * regions must be restarted. Note that the * * restarts do not need to occur at the same * * time. * **************************************************************** During the AOR activation, if a region is defined as optimized target region, flag WAOR_OPT_ENABLE is turned on, and method EYU0WNRS (WNRS) calls module DFHRSSR to open the CFDT (Coupling Facility Data Table) file for region status data storage. If RS (Region Status) server is not available at that time, the CFDT file fails to open, RSSR_EXCEPTION is returned, and message DFHFC7085 is issued to indicate the failure. Every 15 seconds, method EYU0WNHD (WNHD) is driven on the MAS region for WLM heart-beat processing. As part of the processing, WNHD validates flag WAOR_OPT_ENABLE and other conditions. If the flag is on, and other conditions match, DFHRSSR is called to open the CFDT file. However, the flag WAOR_OPT_ENABLE is turned off by WNRS after the failure of DFHRSSR call. As a result, the DFHRSSR call in WNHD is ignored, and the target region doesn't try to reconnect to the RS server.
Problem conclusion
Method EYU0WNRS has been updated to turn off flag WAOR_OPT_ENABLE only if the failure returned from DFHRSSR is caused by incorrect pool name.
