PK20149: INCREMENTAL IMAGE COPY BATCH FUNCTION DOES NOT ALLOW A RECOVERY UNLESS A /DBR IS DONE.

APAR status

• Closed as program error.

Error description

• While testing DRF Beta and Incremental Image Copy batch function
  - stop a database and take a batch image copy.
  - start the database, and enter online transactions which will
    update the database
  - /DBR the database without NOFEOV, which produces a SLDS
  containing the database updates.
  - start the database.
  - submit the batch DRF IIC job.
  
  - **  batch DRF job goes into a wait state and displays the
    following message -
   FRD6003I SYTUND   SYTUND    AUTHORIZED BY  PROD
  

Local fix

• If a /DBR is done to the database, then the DRF batch job
  completes.

  DRF has been changed to take both batch and concurrent ICRs
  (incremental image copies).  If all the required logs are
  available, the image copy is registered to DBRC as batch and the
  RUNTIME is the current time.  If only a subset of the required
  logs are available, the image copy is registered as concurrent
  and the RUNTIME is the latest stoptime of all the log data sets
  used.  The STOPTIME of this image copy is the current time.

  DRF has been changed with APAR PK21934 to take both batch and
  concurrent ICRs (incremental image copies).  If all the required
  logs are available image copy is registered to DBRC as batch and
  the RUNTIME is the current time.  If only a subset of the
  required logs are available image copy is registered concurrent
  and the RUNTIME is the latest stoptime of all the log data sets
  used.  The STOPTIME of this image copy is the current time.
  
  If there have been no changes since the last image copy, meaning
  that an image copy record with the same RUNTIME exists, DRF
  issues message FRD6022A with the reason IMAGE COPY ALREADY TAKEN
  
  Message 'FRD6003I dbname AUTHORIZED BY ssid' is issued when an
  ADD control statement is processed if any of the databases are
  authorized.  This is partly for information only. This message
  is no longer issued when OUTPUT(ICR) is specified.
  
  Incremental image copies to a specified time (or what would be
  called timestamp incremental image copy) are not allowed. The
  RCVTIME parameter on the START control statement is not allowed
  when OUTPUT(ICR) is specified.  Error message FRD6124A INVALID
  DATA ENCOUNTERED.  KEYWORD: RCVTIME   RSN=SPECIFIC VALUE OF
  RCVTIME IS NOT ALLOWED FOR AN INCREMENTAL IMAGE COPY is issued
  and the job fails.  An image copy can be created as part of the
  normal recovery process, but an incremental image copy is not
  designed for timestamp image copies.
  
  DRF has also been changed to call auxilliary utilities with the
  correct list of DBDSs and areas to be processed.  Only those
  that can be recovered are passed.
  
  ----
  The following changes are made to the IMS Database Recovery
  Facility for z/OS User's Guide and Reference Version 3 Release 1
  manual number SC18-9407-00.
  
  Message FRD6022A adds a new reason:
  IMAGE COPY ALREADY TAKEN
      OUTPUT(ICR) option was specified, however there have been
      no changes since the last incremental image copy was
      taken.
  
  The System action for this reason is:
      This is not an error situation but an informational
      message.  No action is required.
  
  Message FRD6124A adds a new reason:
  SPECIFIC VALUE OF RCVTIME IS NOT ALLOWED FOR AN INCREMENTAL
  IMAGE COPY
      The OUTPUT(ICR) option was specified and RCVTIME was
      specified on the RECOVER START input control statement.
      This combination is not allowed, an incremental image copy
      cannot be taken to a specified time. If a timestamp recovery
      is desired along with an image copy, remove the OUTPUT(ICR)
      option.
  
  On page 72 under the IC option of the ADD control statement,
  there is a paragraph beginning with 'Only the batch image copy
  feature of HPIC is available ...' After this paragrpafh, add
  the following:
     When the OUTPUT(ICR) option is specified, the incremental
     image copy created may be batch or concurrent.  A concurrent
     image copy is created when only a subset of the required logs
     are available.  The RUNTIME used to register the image copy
     to DBRC is the latest stoptime of all the log data sets used
     as input.  It is not necessary to stop the database for an
     incremental image copy.
