PK46170: PROVIDE THE V7 PRECOMPILER ON DB2 UDB FOR Z/OS V8

Obtain the fix for this APAR

APAR status

• Closed as new function.

Error description

• This APAR will provide the V7 DB2 UDB for OS/390 and z/OS
  Precompiler with DB2 UDB for z/OS V8 to allow customers to
  migrate to V8 more easily.
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users migrating from DB2 UDB for z/OS and *
  * OS/390 V7 to DB2 UDB for z/OS V8 and *
  * needing to re-precompile COBOL and PL/I *
  * applications. *
  ****************************************************************
  * PROBLEM DESCRIPTION: The DB2 UDB for z/OS V8 Precompiler *
  * requires supported COBOL and PL/I *
  * compilers. The V8 Precompiler should *
  * not be used with unsupported compilers. *
  * *
  * Compiling COBOL and PL/I programs *
  * precompiled with the V8 Precompiler *
  * may result in compile failures if *
  * unsupported compilers are used. *
  * *
  * This apar provides a precompiler on V8 *
  * that is nearly identical to the V7 *
  * Precompiler, which does not require *
  * migration to supported COBOL and PL/I *
  * compilers. This is to aid in *
  * migration from V7 to V8. *
  ****************************************************************
  * RECOMMENDATION: *
  ****************************************************************
  Some COBOL and PL/I compilers are no longer supported by DB2 for
  z/OS Version 8, but were handled by the DB2 Version 7
  precompiler.
  
  This APAR provides a precompiler that is very similar to the DB2
  for z/OS Version 7 precompiler on DB2 for z/OS Version 8.
  After applying this APAR, you can use a "V7 version of the
  precompiler" that allows you to precompile applications that
  have dependencies on those unsupported COBOL and PL/I compilers.
  This precompiler is meant only to ease the transition from
  unsupported compilers to supported compilers and has a number
  of differences and restrictions.
  
  The load module name is DSNHPC7.
  
  The HOST precompiler option for host language only permits
  COBOL, COB2, and PLI. If any other value is specified, this
  precompiler will issue a warning message (DSNH024I) and default
  to HOST(COB2).
  
  The following precompiler options and invocations are not
  supported:
  DB2 coprocessor
  SQL procedures, i.e. HOST(SQL)
  schema processor
  FIPS flagging
  
  This precompiler is available only for DB2 for z/OS Version 8.
  This precompiler produces DB2 for z/OS Version 7 DBRMs, and does
  not support any capability that is new to DB2 for z/OS
  Version 8.
  
  This precompiler does not support any SQL other than that of
  DB2 for z/OS Version 7. In particular, none of the new changes
  for DB2 for z/OS Version 8 is included.
  SQL processed by this module is not completely compatible
  with the later versions. See the Installation Guide sections on
  incompatible changes for more information on this subject.
  
  No program preparation help, including JCL, CLIST or DB2I
  support, is provided for this precompiler. You can take existing
  JCL from Version 8 and change the program name to PGM=DSNHPC7.
  If you use Version 7 JCL, you must also change SDSNEXIT and
  SDSNLOAD to the Version 8 libraries. This precompiler can use
  either the DB2 Version 7 or the DB2 Version 8 level of DSNHDECP.
  
  Support statement:
  This module is part of DB2 for z/OS Version 8, with the same
  terms and conditions as the rest of that product. It is in
  service while DB2 Version 8 is in service. Language support
  is not affected by this change. If a supported host language
  compiler currently works with the Version 7 precompiler, it
  should work with this precompiler module. Although no warranty
  is expressed or implied, limited testing was performed with the
  following compilers (with associated end of service or EOS
  dates):
  * OS/VS COBOL V1.2.4 EOS 6/1994
  * OS PL/I 1.5 EOS 12/1995 (PL/I Opt. V1.5.1)
  * VS COBOL II V1R4 EOS 3/2001
  * OS PL/I 2.3 EOS 12/2003
  
  Positioning:
  If your source code works with the DB2 for z/OS Version 8
  precompiler, you should use the newer precompiler. Using the
  current precompiler provides better support and reduces the
  total work effort. This module is provided in DB2 for z/OS
  Version 8 only to allow customers to move more quickly to
  DB2 for z/OS Version 8 before moving all applications to
  current compilers. Migration to current compilers can be
  delayed, but not avoided by this technique. Customers need
  to move to current compilers while running DB2 Version 8.
