Displaying the log stream status

To determine if an MVS™ log stream is currently connected to CICS® VR VSAM batch logging, and to inquire about the status of the connection, you can issue the operator command shown below.

DISPLAY SMS,CICSVR,LOGSTREAMS(log stream name)
where log stream name is the name of an MVS log stream to which CICS VR VSAM batch logging is connected. The log stream can either be a forward recovery log stream or an undo log stream. For example, CICS VR VSAM batch logging connects to the log stream specified in the LOGSTREAMID catalog parameter of a VSAM data set that is enabled for CICS VR forward recovery logging (FRLOG=REDO) when a batch job that updates the data set is run. If the specified log stream is not currently connected to CICS VR VSAM batch logging, then the log stream connection status is blank. See Setting up CICS VR VSAM batch logging, for more information about enabling CICS VR VSAM batch logging.

To display the status of the connection of all MVS log streams currently connected to CICS VR VSAM batch logging, you can issue the following operator command:

DISPLAY SMS,CICSVR,LOGSTREAMS(ALL)
where ALL specifies that CICS VR must display the status of all MVS log streams, forward recovery and undo log streams, that are currently connected to CICS VR VSAM batch logging by all CICS VR systems in the same XCF group. Again, an MVS log stream is connected to CICS VR VSAM batch logging when a batch job that starts CICS VR forward recovery logging or CICS VR undo logging is run.

Issuing the DISPLAY SMS,CICSVR,LOGSTREAMS, log stream name, or DISPLAY SMS,CICSVR,LOGSTREAMS(ALL) command produces output similar to the example in Figure 1:

  CICSMVS.TTCICS2.FILELOG2    SS.............................. 
                                                               
  01  SYSNAME:  SYSTEM1                                        
  02  SYSNAME:  SYSTEM2                                        

Refer to the description of message DWW020I in CICS VR Messages and Problem Determination for an explanation of the reported log stream connection status.

Note: If DISPLAY SMS,CICSVR,LOGSTREAMS, log stream name, is issued, but the specified log stream is not currently connected to CICS VR VSAM batch logging, the log stream connection status field is blank. If DISPLAY SMS,CICSVR,LOGSTREAMS(ALL) is issued, but no batch jobs that start CICS VR VSAM batch logging are currently running, no log streams are reported in the produced output.
