Changing the Unique GTT Selector Option

This procedure is used to change the unique GTT selector option using the chg-sccpopts command with this parameter.

:unqgttsel – This parameter specifies whether a GTT selector search is performed on overlapped GTT selectors. This parameter has two values.

• bestmatch - Overlapped GTT selectors are searched if non-overlapped GTT selectors are not found.
• exactmatch - Only non-overlapped GTT selectors are searched.

1. Display the existing unique GTT selector option value by entering the rtrv-sccpopts command.

   This is an example of the possible output.

   The rtrv-sccpopts output contains other fields that are not used in this procedure. If you wish to see these fields, refer to the rtrv-sccpopts command description in the Commands Manual.

2. Change the unique GTT selector option value by entering the chg-sccpopts command with the unqgttsel parameter.

   For this example, enter this command.

   chg-sccpopts:unqgttsel=exactmatch

   When the chg-sccpopts command has successfully completed, this message should appear.

   CHG-STPOPTS: MASP A - COMPLTD

3. Verify the changes using the rtrv-sccpopts command. This is an example of the possible output.

   rlghncxa03w 10-07-17 16:02:05 GMT  EAGLE5 42.0.0
   
   SCCP OPTIONS
   -------------------------------

   The rtrv-sccpopts output contains other fields that are not used in this procedure. If you wish to see these fields, refer to the rtrv-sccpopts command description in Commands User's Guide.

4. Back up the new changes using the chg-db:action=backup:dest=fixed command. These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

   BACKUP (FIXED) : MASP A - Backup starts on active MASP.
   BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
   BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
