IC99680: SEGMENTATION FAULT AND CRASH DURING DSMSERV FORMAT COMMAND

 

 

APAR status

• Closed as program error.

   

Error description

• The dsmserv format process can crash with a segmentation fault
  when initiated by an administrator during manual instance
  configuration.  For example:
  
  $ /opt/tivoli/tsm/server/bin/dsmserv format dbdir=/tsmdb
    activelogdir=/tsmlog archlogdir=/tsmarchlog
    activelogsize=5120

Local fix

• The segmentation fault can be ignored.  The dsmserv format
  operation completes with success.  Alternatively, enable the
  DB2NOEXITLIST=ON DB2 registry variable to avoid the crash.
  Use the command "db2set DB2NOEXITLIST=ON" prior
  to executing the "dsmserv format ..." command.
  DB2NOEXITLIST should not be set back to OFF after the
  "dsmserv format ..." has been completed.

  ****************************************************************
  In addition to the symptom described in the ERROR DESCRIPTION
  the following symptom may be observed:
  
  When DSMSERV FORMAT or DSMSERV LOADFORMAT commands are run on
  a system that uses a locale other than the English regional
  locale, the Tivoli Storage Manager Server should automatically
  set the DB2CODEPAGE to 819. It will fail to do so when this
  APAR is encountered.
  
  Tivoli Storage Manager Versions Affected:
  All 7.1 Server versions on all platforms
  
  Customer/L2 Diagnostics:

  the issue occurred.

            handle "".
  
  Additional Local Fix:
  Before issuing the DSMSERV FORMAT or DSMSERV LOADFORMAT command,
  log on to the system as the server instance owner and issue this
  command:
  
  db2set -i instance_name DB2CODEPAGE=819
  
  
  The code changes made to correct IC99680 address a general
  issue with the sequence in which the TSM server sets DB2
  variables with the  "db2set" command. The first symptom is
  related to the DB2NOEXITLIST DB2 variable, the second symptom
  is related to the DB2CODEPAGE variable.
