IT27242: LOGARCHMETH2 OFF NOT UPDATED ON HADR STANDBY

APAR status

• Closed as program error.

Error description

• Setting DB CFG parameter LOGARCHMETH2 to OFF in an HADR Standby
  database will not take effect even after a restart of the
  Standby database.
  Once this Standby takes over the Primary role, it will still try
  archiving to archive method 2.
  
  In db2diag.log it might show references to LOGARCHMETH2, .e.g:
  EDUID : 2222 EDUNAME: db2logmgr (DB) 0
  FUNCTION: DB2 UDB, data protection services,
  sqlpgRetryFailedArchive, probe:4780
  MESSAGE : Still unable to archive log file 129821 due to rc
  -2045771739 for
  LOGARCHMETH2 using ...
  
  Using "ps -elf | grep meth" it shows db2vend process
  db2logmgr.meth2 - (database_name), which is not expected when
  LOGARCHMETH2 is OFF.
  
  A side effect could be a disk full situation for the active log
  directory.
  This may happen, when archive method 1 works, but the archive
  method 2  target does not do any more work (e.g. a vendor
  product was switched off) and no failarchpath has been
  defined.
  

Local fix

• LOGARCHMETH2 OFF only takes effect when the database is
  restarted while being in the new Primary role.
