PM73047: COPYDBRC FUNCTION ALLOCATES NEW DATASET NAMES WITH INCORRECT SUFFIX

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HALDB Toolkit V3R2 COPYDBRC Function Allocates New Dataset
  Names With Incorrect Suffix.
  HALDB Toolkit  generated IDCAMS ALLOCATE statements incorrectly
  based on Partition Name sequence (WMGAT1A is listed before
  WMGAT11), rather than on Partition ID # seuence (WMGAT11 is
  partition 1 and WMGAT1A is partition 10). This is why incorrect
  Partition DSN suffixes are seen in the new RECONs.

  ****************************************************************
  * PROBLEM DESCRIPTION: In one given case, the COPYDBRC         *
  *                      function issues incorrect IDCAMS        *
  *                      DELETE, DEFINE, and ALLOCATE statements *
  *                      for ostensibly new Partition data set   *
  *                      names. These data set names are         *
  *                      supposed to be seen in the copied       *
  *                      RECONs as being associated with         *
  *                      specific Partition Numbers and their    *
  *                      corresponding Partition Names, but      *
  *                      they are not.                           *
  *                      .                                       *
  *                      This happens when the Partition Names   *
  *                      given on the INIT.PART commands occur   *
  *                      in EBCDIC collating sequence different  *
  *                      from the Partition Number sequence      *
  *                      assigned by DBRC when COPYDBRC issues   *
  *                      the INIT.PART commands for the new      *
  *                      Partitions in the copied RECONs.        *
  *                      .                                       *
  *                      For example: There are two Partitions   *
  *                      named PARTX11 and PARTX1A. When reading *
  *                      the original RECONs, COPYDBRC finds     *
  *                      the Partition Number for PARTX11 is one *
  *                      and the Partition Number for PART1A is  *
  *                      two. Thus, the COPYDBRC function        *
  *                      correctly issues the INIT.PART for      *
  *                      PARTX11 first and for PARTX1A second.   *
  *                      .                                       *
  *                      Notice that the EBCDIC collating        *
  *                      sequence for the Partition Names is     *
  *                      PARTX1A then PARTX11.                   *
  *                      .                                       *
  *                      In later processing, COPYDBRC issues    *
  *                      IDCAMS ALLOCATE commands for the two    *
  *                      Partition Names based on the order that *
  *                      DBRC presents them when COPYDBRC        *
  *                      internally issues a LIST.DB for their   *
  *                      Master DBD. The order presented by DBRC *
  *                      is in EBCDIC collating sequence of      *
  *                      of the Partition Names not by Partition *
  *                      Number. Thus, COPYDBRC incorrectly      *
  *                      assigns Partition data set Name Suffix  *
  *                      00001 to PARTX1A and Partition data set *
  *                      Name Suffix 00002 to PARTX11 when it    *
  *                      issues the IDCAMS DELETE, DEFINE and    *
  *                      ALLOCATE commands.                      *

Problem conclusion

• The COPYDBRC source code has been changed to ensure that
  Partition data set Name Suffixes are assigned in Partition
  Number sequence, rather than EBCDIC collating sequence of
  Partition Name.
