DSNJ128I LOG OFFLOAD TASK FAILED FOR ACTIVE LOG nnnnn

Explanation

The offload task abended while attempting to offload the relative byte address (RBA) range in active log data set 'nnnnn'.

System action

The offload task terminates and the archive data sets allocated to the offload task are deallocated and deleted. The status of the active log data sets involved in the failed offload processing remains set to 'not reusable'.

The log offload task will be re-initiated by one of several events. The most common are:
  • All the available space in the current active log data set has been used (normal case).
  • A DSNJ110E message is issued.
  • The database system services address space (ssnmMSTR) is started, but data in the active log has not been archived.
  • An I/O error occurs on the active log, which will force the system to truncate and offload the active log data set, and switch to a new active log data set.

Operator response

This message is the result of an offload failure, and will be preceded by one or more Db2 messages (for example, DSNJ073I) and/or MVS ABEND messages (for example, IEC030I, IEC031I, IEC032I). If Db2 is operating with restricted active log resources (see message DSNJ110E), quiesce the system to restrict logging activity until the ABEND or the DSNJ110E condition can be resolved. Notify the system programmer.

System programmer response

This message is the result of an offload failure, and will be preceded by one or more Db2 messages (for example, DSNJ073I) and/or MVS ABEND messages (for example, IEC030I, IEC031I IEC032I). Investigate and correct the cause of the ABEND before the offload is attempted again by Db2.

Problem determination

This message is the result of an offload ABEND and will be preceded by one or more Db2 messages and/or MVS ABEND messages. See the documentation for the associated Db2 and/or MVS messages to formulate a course of corrective action. Use the print log map (DSNJU004) utility to print the BSDS (both copies if running in dual mode), and then use the DSNJU004 output to determine the current status of the active and archive log data sets.

This message can be generated for a variety of reasons. However, the most likely are:
  • Archive log data set allocation errors. Refer to the text for message DSNJ103I for corrective action.
  • The size of the archive log data set is too small to contain the active log data set(s) during offload processing. All secondary space allocations have been used. This condition is normally accompanied by MVS ABEND message IEC030I.
  • All available space on the DASD volume(s) to which the archive data set is being written has been exhausted. This condition is normally accompanied by MVS ABEND message IEC032I.
  • The primary space allocation for the archive log data set (as specified in subsystem parameters) is too large to allocate to any available online DASD device. This condition is normally accompanied by MVS ABEND message IEC032I.
