APAR status

• Closed as program error.

Error description

• Image Copy for a DB was taken twice due to mistake.
  First time, it had been taken with volser=IC0001.(IC cataloged.)
  
   Then, it was noticed that the volser was wrong, It should have
  been volser=IC0000. The RECON d/s,was restored and the IC was
  taken again(IC not cataloged, because of same d/s name )
  
  We did not delete the old IC catalog for the first DB, then the
  old catalog

  The IMS Database Recovery Facility for z/OS User's Guide
  erroneously documents the CATDS environmental control statement
  as an option the user can utilize to override the DBRC CATDS
  flag.  The DRF CATDS was not intended to be a general use
  override for DRF to determine if the attributes of input data
  sets (Image Copies, Logs, CAs) should be used from the RECON or
  from the Catalog.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  The DRF User's Guide is changed to remove the CATDS
  environmental control statement.  It is currently documented
  and invoked by users with the intention of it being a useable
  override to the DBRC CATDS setting or to the method used by DRF
  in locating data set attributes for dynamic allocation.  DRF is
  designed to always reference the RECON for data set attributes
  and search the CATALOG for new information.  The design was
  introduced in an IMS V8 APAR PQ60701/UQ66887.  The CATDS
  control statement became obsolete after subsequent code changes
  were made in PK12681/UK10553.  Code is not changed in this APAR
  to remove CATDS for compatibility.
  
  The following DOC changes are required:
  --
  IMS Database Recovery Facility for z/OS User's Guide and
  Reference Version 2 Release 1 (SC18-7016-03)
  
  and...
  
  IMS Database Recovery Facility for z/OS User's Guide and
  Reference Version 3 Release 1 (SC18-9407-00)
  
  In...
  Chapter 3. Defining and Tailoring the IMS Database Recovery
  Environment
  
  Remove the "CATDS(Y|N|D)" description.
