PH44600: NEWLY ADDED LOGS BY DEFINE LOG ARE NOT USED AFTER CSQJ111A ISSUED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After CSQJ111A is issued due to the active log filling, any
  tasks attempting to write to the logs are suspended until log
  space becomes available again.
  The correct behavior is that logging should resume when either:
  1) A successful log archive offload makes an existing active
  log eligible to be reused
  or
  2) DEFINE LOG is used to add a new active log dataset
  .
  However due to the error, if offloads are enabled only a
  successful offload will cause logging to be resumed, and
  logging will not be resumed when additional logs are added by
  DEFINE LOG. Further, if DEFINE LOG is used prior to a
  successful offload logging will remain suspended even after the
  log offload completes.
  

Local fix

• In order to recover from CSQJ111A without a fix the customer
  would need to ensure that log offloading can succeed, and that
  DEFINE LOG is not issued.

  * PROBLEM DESCRIPTION: After CSQJ111A is issued and DEFINE LOG *
  *                      is used to add additional logs          *
  *                      dynamically, logging remains suspended  *
  *                      if archive log offloading is enabled.   *
  ****************************************************************
  When the last available log fills CSQJ111A is issued and logging
  is suspended until additional log space is available. If log
  offloading is enabled, a request to offload logs is scheduled,
  however this can be delayed - for example by a configuration
  error or unavailable tape system.
  DEFINE LOG can be used to dynamically add another log data set,
  however this does not resume logging, and prevents it being
  resumed when offloading continues.
  

Problem conclusion

• DEFINE LOG processing is changed to resume the logger task when
  an additional log is dynamically added while in a log full
  situation.
