PQ84262: LOG ARCHIVES INTERMITTENTLY FAIL WITH MESSAGE DSNJ128I

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In ALC Cache mode there may be intermittent cases were a DCB can
  not be validated.  When this happens, Archive Log Compress will
  bypass dataset CLOSE processing and - as a result - DB2 will
  fail to archive the log and issue message DSNJ128I.
  
  This APAR will modify the ALC close handler to correctly handle
  all condition codes of the TPROT. Specifically, if the TPROT
  fails due to a translation failure then ALC CLOSE will add
  an 'address validity checking' process to determine if the
  translation failure is due to the storage being paged out, or it
  if is truly a bad address.
