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
  read this text. To access the latest on-line
  documentation, go to the product library page at:
  
  http://www.ibm.com/software/webservers/appserv/library
  
  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)
  (reserved) (reserved) (reserved)
  
  Action: None.
  
  APAR PM26377 is currently targeted for inclusion in Service
  Level (Fix Pack) 7.0.0.17 of WebSphere Application Server V7.0.
