PM86518: RAS: IVP SPOC ENCOUNTERS CORRUPTED AUDIT TRAIL LOGSTREAM

APAR status

• Closed as duplicate of another APAR.

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
