Error description

  • when using TSO SPOC function "audit log" we get the
    message
    CSLM130I Unable to connect to the log stream
    which is invalid for we specified the right auditlog name.
    Using DFSERA10 with EXITR=CSLULALE and same auditlog we get a
    valid
    result accompanied by message
    IXG513I LOGGER SUBSYSTEM (LOGR) EXIT ENCOUNTERED POSSIBLE LOSS
    OF DATA
    DD=SYSUT1  LOGSTREAM=IMSN.OMAUDIT.TRAIL
    I suppose data loss condition is not correctly taken into
    account in
    TSO SPOC.
    internal investigation at FI revealed that the OM audit trail
    logstream
    is defined with
    STG_DUPLEX(NO) DUPLEXMODE()
    in the LOGR policy , hence is vulnerable to data loss .
    According to
    system logger documentation STG_DUPLEX(NO) is default . So the
    root
    cause for the possible logstream gap is laid in
    INSTALIB(IV3E307T) i.e.
    skeleton DFSIXSOF which does  NOT specify STG_DUPLEX .
    Concrete question to IBM IMS support is :
    What is the recommened setting for STG_DUPLEX for the OM audit
    trail
    logstream ?
    The recommendation is to have STG_DUPLEX(YES)
    specified in both the OM and for CQS.
    the IVP should be updated to provide this parm

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All IMS V11 IVP users                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: MSGCSLM130I encountered using IVP SPOC  *
    *                      when the default IVP settings are used  *
    *                      to define the OM audit trail logstream. *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    When the default IVP settings were used to define the OM audit
    trail logstream, and the audit trail logstream was accessed by
    SPOC, the following ISPF message was encountered:
    
      CSLM130I Unable to connect to the log stream
    
    This message is issued under ISPF when SPOC can not connect to
    the audit trail logstream specified. This is a normal response
    to a condition caused by environmental factors where data loss
    may have occured affecting the logstream.
    
    The default IVP settings for the logstream are acceptable for
    most users, but some will have more stringent requirements for
    this facility.  The logstream definition values for users with
    more stringent requirements are not well documented, nor is it
    mentioned that different settings should be considered.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    The following modules were updated to address this problem:
    
    DFSIXRO0:  The IVP help file for the OM audit trail logstream
               definition step has been updated to include notes
               on the settings that the user should consider.
    
               The information included in the help file has also
               been included in the System Definition Guide under
               separate cover.
