LI73327: IF LOGARCHMETH2 ONLY IS SPECIFIED A ROLLFORWARD CAN FAIL WITH SQL4970N

APAR status

• Closed as program error.

Error description

• In V8.1-8.2 if archival logging is enabled and ONLY
  'logarchmeth2' is specified a ROLL-FORWARD operation will NOT
  attempt to retrieve the logs from the logarchmeth2 path.
  A SQL4970N may be received:
  
  SQL4970N Roll-forward recovery on database "<name>" cannot reach
            the specified stop point (end-of-log or point-in-time)
            because of missing or corrupted log file(s) on
            database partition(s) "<database-partition-list>".
            Roll-forward recovery processing has halted on log
            file
            "<log-file>".
  
  If 'logarchmeth1' is set then db2 WILL look in the path for
  logarchmeth2 and attempt to retrieve the files from there.
  

Local fix

• 1)You can specify the path to the log files in the 'overflow log
  path in the rollforward statement.
  
  2)You can update the DB CFG parameter of OVERFLOWLOGPATH to be
  the location for the logarchmeth2 path. (FULL PATH NEEDE)
  
  3)You can update the DB CFG parameter for LOGARCHMETH1 to a
  valid path.  This will cause DB2 to look in the LOGARCHMETH2
  path for files and enable it to retrieve the archived log files.
  

Problem summary

• IF LOGARCHMETH2 ONLY IS SPECIFIED A ROLLFORWARD CAN FAIL WITH
  SQL4970N
