IT23450: After building a JDBC switch load file on Solaris an AMQ6175 message is thrown as symbol CSCtrl cannot be found

APAR status

• Closed as program error.

Error description

• After linking the jdbcdb2 or jdbcora object file on Solaris to
  the database libraries using the makefile provided by the
  product, an error occurs when an attempt is made to load the
  library for use.  The error reported is as follows:
  
  AMQ6175:
  The system could not dynamically load the shared library
  '/var/mqm/exits64/jdbcora'.
  The system returned error message:
    'ld.so.1: java: fatal: relocation error: file
  /var/mqm/exits64/jdbcora:
    symbol CSCtrl: referenced symbol not found'.
  
  EXPLANATION:
  This message applies to UNIX systems.
  The shared library '/var/mqm/exits64/jdbcora' failed to load
  correctly due to a problem with the library.
  
  
  Listing the library dependencies, for example using the ldd
  command, results in a similar "symbol not found: CSCtrl" message
  being reported.
  

Local fix

• When linking to create the database switch load file, update the
  makefile to link to the mqmcs library as well as mqe.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users who create database switch load files
  for queue manager JTA/JDBC transaction coordination.
  
  
  Platforms affected:
  Solaris x86-64, Solaris SPARC
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A configuration error within the environment used to generate
  the MQ JDBC object files, jdbcdb2 and jdbcora, resulted in
  additional symbols being incorrectly included.  The JDBC object
  files are only linked with the mqe library, as per the makefile
  provided by the product, when building the database switch load
  file which would not permit the additional included symbols to
  be resolved.  As such, at runtime when an attempt to load the
  library was made, the load failed reporting unresolved symbols.
  

Problem conclusion

• The environment used to build the JDBC object files, jdbcdb2 and
  jdbcora, has been updated such that the additional symbols that
  were previously erroneously included are no longer included in
  the object files.
