DWW1323W
VSAM sphere dddd logged on MVS log stream llll from yydddhhmmss to yydddhhmmss local time was also logged on another log stream during this time period.

Explanation

VSAM sphere dddd has been logged on more than one log stream for the time period yydddhhmmss to yydddhhmmss local time. One of the following events might have occurred:
  • Log streams were switched while the sphere was open for processing.
  • Data was lost due to system malfunction.
CICS VR cannot handle this situation without risking data loss.

System action

If this message occurred during the construction of a recovery job using the CICS VR panels, CICS VR has detected that VSAM sphere dddd has been logged on more than one log stream for the time period. During a previous log of logs scan, CICS VR messages DWW1320 and DWW1321 were issued for VSAM sphere dddd indicating that this sphere was also logged on another log stream. The time period for log stream llll was then truncated to remove the overlap. CICS VR cannot handle this situation without risking data loss. This message is accompanied by message DWW1325. A recovery job is built, unless there are other reported errors preventing the job build, but the generated JCL causes the overlapped interval to be ignored for log stream llll.

If this message occurred during a batch log of logs scan, during this or a previous scan CICS VR messages DWW1320 and DWW1321 were issued for VSAM sphere dddd indicating that this sphere was also logged on another log stream during the time period. The time period for log stream llll was then truncated to remove the overlap. This message is accompanied by message DWW1325. A recovery report is built, unless there are other reported errors preventing the report build. The job steps in the report cause the overlapped interval to be ignored for log stream llll, which could present and integrity exposure.

User response

See messages DWW1320 and DWW1321 for more information. Do not run the job or use the information in the recovery report that CICS VR created for you until you ensure that all the updates on MVS log stream llll that CICS VR ignored are not required. Take the actions recommended in messages DWW1320 and DWW1321.
