IJ38035: THE NUMBER OF ENTRIES IN THE GLOBAL LOCATION BROKER OF A DISTRIBUTED HUB STEADILY INCREASES

IBM Tivoli Monitoring 6.3.0 Fix Pack 7 Service Pack 12 (6.3.0.7-TIV-ITM-SP0012)

APAR status

• Closed as program error.

Error description

• During initialisation, an RTEMS registers an entry in the Hub's
  Global Location Broker for each interface and protocol that it
  supports.
  Before doing so, it first unregisters all interfaces that it
  registered when it last started.
  SNA addresses registered by a z/OS RTEMS in the Global Location
  Broker of a distributed Hub are not removed.
  Consequently, a z/OS RTEMS that is configured to use SNA will
  add duplicate SNA registrations to the GLB each time it is
  started.

Local fix

• The code was changed to correctly remove SNA addresses from the
  GLB when they are unregistered
