APAR status

  • Closed as program error.

Error description

  • Customers can configure the shared-library region size in
    BPXPRMxx in parmlib.  This value applies to every address
    space.  In 31 bit this constrains the amount of space
    available for the Java heap. Some customers have configured
    the value to be too large and get in trouble.  For that reason
    we added message BBOO0341I.
    
    USS has now added _BPXK_DISABLE_SHLIB which can change
    what the value is for a particular address space.  Message
    BBOO0341I needs to be updated print out the value affected
    by the _BPXK_DISABLE_SHLIB setting (field PrliShlibRgnSize
    from bpxyprli).

    ****************************************************************
    The shared library region size is specified in BPXPRMxx in
    parmlib.  This value applies to every address space.  In 31 bit
    this constrains the amount of space available for the Java
    heap.  Some customers have configured the value to be too large
    and get in trouble.  For that reason we added message BBOO0341I
    to display this value on startup.
    
    UNIX System Services (USS) has introduced a new environmental
    property, _BPXK_DISABLE_SHLIB, which can change what the value
    is for a particular address space.
    
    WebSphere for z/OS Application Server needs to update diagnostic
    message BBOO0341I to display the value associated with the new
    USS environmental property _BPXK_DISABLE_SHLIB.
    

Problem conclusion

  • Code has been modified to display the shared library region
    size associated with the USS environmental property
    _BPXK_DISABLE_SHLIB in message BBOO0341I.
    
    APAR PM26377 requires changes to documentation.
    
    NOTE: Periodically, we refresh the documentation on our
    Web site, so the changes might have been made before you

    The following change to the Version 7.0 Information
    Center will be made available in May, 2011.
    
    The description of the BBOO0341I messages that is
    included in the Version 7.0 Information Center will
    be updated to read as follows:
    
    BBOO0341I: VARIOUS RESOURCE MONITORING DATA:
    ({0}):({1}):():():():():():():():()
    
    Explanation: Provides various resource monitoring data retrieved
    from the kernel. The fields of the message are defined below:
    (maximum shared library region size in MB) (process level
    information (prli) shared library region size, if available)
    (reserved) (reserved) (reserved) (reserved) (reserved)
