PH37493: OSGI.CONFIGURATION.AREA.READONLY=TRUE NOT TAKING AFFECT FOR SERVANT REGION

APAR status

• Closed as program error.

Error description

• -Dosgi.configuration.area.readOnly=true doesn't take affect in
  the servant region because there is logic in the OSGI to check
  if the server has crashed.  This logic doesn't work correctly in
  a control/servant/adjunct environment.  So the check will be
  disabled on z/OS.

  ****************************************************************
  The WAS bootstrap logic includes an attempt at detecting whether
  the server has crashed without a proper shutdown in its previous
  instance, in which case the OSGi framework is started in "clean"
  mode (discarding and rebuilding the contents of the OSGi
  configuration area). When that clean start is performed, some
  configuration options, particularly the option to process the
  configuration in read-only mode, are unavailable.
  On z/OS, it was determined that the crash detection logic was
  faulty, detecting a "crash" on every server start and attempting
  a clean OSGi framework start. Because of this, the read-only
  property could never effectively be enabled.
  

Problem conclusion

• The crash detection logic and automatic OSGi clean was disabled
  z/OS. Customers experiencing crashes should manually run the
  osgiCfgInit.sh script before their next server startup.
  
  The fix for this APAR is targeted for inclusion in fix packs
  8.5.5.21 and 9.0.5.11. For more information, see 'Recommended
