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.
