Removing a Screen Set

This procedure is used to remove a screen set from the database using the dlt-scrset command. The parameters used by the dlt-scrset command are shown in the Gateway Screening Attributes section. The general rules that apply to configuring gateway screening entities are shown in the Gateway Screening Configuration section.

The example in this procedure removes the screen set gws1 from the database.

Display all screen sets in the database using the rtrv-scrset command.

The following is an example of the possible output.

The screen set to be removed cannot be referenced by a linkset.

To verify this, enter the rtrv-ls command. If the output shows a reference to the screen set to be removed, perform the Changing an SS7 Linkset procedure in the Database Administration Manual – SS7 and change the scrn parameter to reference another screen set, or to none to remove the reference to the screen set.
Remove the screen set from the database using the dlt-scrset command.
For this example, enter this command.

dlt-scrset:scrn=gws1

A message similar to the following should appear.
```
rlghncxa03w 06-10-25 15:26:30 GMT  EAGLE5 36.0.0
DLT-SCRSET: SCREEN SET AFFECTED - GWS1  0% FULL
DLT-SCRSET: MASP A - COMPLTD
```
Verify the changes using the rtrv-scrset command with the screen set name used in step 3.
For this example, enter this command.

rtrv-scrset:scrn=gws1

The following is an example of the possible output.
```
E2573 Cmd Rej: SR or NSR does not reference an existing SR
```
This message shows that the specified screen set name is not in the database and the action of the dlt-scrset command in step 3 was successful.

Backup the new changes using the chg-db:action=backup:dest=fixed command.

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