  Change Description:
  
  For the ACCRDB command, change the note following the
  PRDDTA instance variable to say:
  
  See the requester accounting information.

  V3 Book Title: Usage of Distributed Data Management Commands
  Pages: 7
  Change Description:
  
  Add the following information after the ACCRDB command
  tables:
  
  Requester Accounting Information
  
  DB2 application servers (AS) accept thread accounting
  information from an application requester in the PRDDTA
  instance variable of the ACCRDB command.  The data must
  be in one or more repeating groups of:
  
  L     One-byte length of the data that follows. The length
        can be zero if no data follows for this group.
  
  Data  Data for length L.
  
  If the length of all repeating groups equals the total
  length of the PRDDTA, DB2 assumes the first group is
  accounting data.  This accounting data appears in the
  DDF portion of the DB2 accounting record mapped by
  macro DSNDQMDA in the DSN310.SDSNMACS library.
  
  In the following examples, the first 8 bytes of accounting
  data should be the AR's PRDID. The following examples of
  PRDDTA include the DDM LLCP.
  
  Figure one shows an example of one group and figure 2 shows
  an example of four repeating groups.  All values are
  expressed in hexadecimal.

  Broken down, the PRDDTA data is:
  
  (LLCP)
  00152104  LL (0015) is the total length of PRDDTA
            and CP (2104) is the code point for PRDDTA.
  
  (First and only group)
    10 (length of group 1 data)
        10 bytes of data of which the first 8 bytes is the
        PRDID followed by the accounting data
  
  The length of the PRDDTA is calculated by adding the
  following parts:
  
   04  bytes of LLCP
   01  length byte for group 1
   10  bytes of data in group 1
   __
   15  LL portion of LLCP
  
  Because the sum of the parts equals LL, DB2 assumes
  that the first group contains accounting data.

  Broken down, the PRDDTA data is:
  
  (LLCP)
  00222104  LL (0022) is the total length of the PRDDTA
            and CP (2104) is the code point for PRDDTA.
  
  (First group)
     10 (length of group 1 data)
         10 bytes of data of which the first 8 bytes is the
         PRDID followed by the accounting data
  
  (Second group)
     08  (length of group 2 data)
          8 bytes of data which DB2 ignores
  
  (Third group)
     00  (length of group 3 data)
          0 bytes of data which DB2 ignores
  
  (Fourth group)
     02  (length of group 4 data)
          2 bytes of data which DB2 ignores
  
  The length of the PRDDTA is calculated by adding the
  following parts:
  
   04  bytes of LLCP
   01  byte length for group 1
   10  bytes of data in group 1
   01  byte length of group 2
   08  bytes of data in group 2
   01  byte length for group 3
   00  bytes of data in group 3
   01  byte length for group 4
   02  bytes of data in group 4
   __
   22  LL portion of LLCP
  
  Because the sum of the parts equals LL, DB2 assumes
  that the  first group contains accounting data.
