Changing a Screen Set

This procedure is used to change the attributes of a screen set in the database using the chg-scrset command. The parameters used by the chg-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 is used to change screen set ls01 to screen set ls05 with the nsfi=blkopc and nsr=ls08.

If the screen set name is being changed, the new screen set name cannot already exist in the database.

The screen set can reference one of the following screens.

• Allowed OPC
• Blocked OPC
• Allowed SIO
• Allowed DPC
• Blocked DPC

Verifying the Gateway Screening Configuration

Enter the following commands to verify that these screens are in the database.

• rtrv-scr-opc:all=yes
• rtrv-scr-blkopc:all=yes
• rtrv-scr-sio:all=yes
• rtrv-scr-dpc:all=yes
• rtrv-scr-blkdpc:all=yes

Gateway Screening Configuration Procedures

If the desired screen is not in the database, perform one of the following procedures to add the desired screen to the database or change an existing screen in the database.

• Adding an Allowed OPC Screen
• Adding a Blocked OPC Screen
• Adding an Allowed SIO Screen
• Adding an Allowed DPC Screen
• Adding a Blocked DPC Screen
• Changing an Allowed OPC Screen
• Changing a Blocked OPC Screen
• Changing an Allowed SIO Screen

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

   The following is an example of the possible output.

   ENTIRE GWS DATABASE IS 1% FULL
   CDPA + AFTPC TABLES ARE 1% FULL

   THE FOLLOWING ARE OVER 80% FULL:

   ss04  OPC     opc1      51%  2075   22      NO
   ss07  OPC     opc1      51%  2075   22      YES
   ss09  OPC     opc1      51%  2075   22      NO
   ss28  OPC     opc1      51%  2075   22      YES
   tup1  OPC     tup1       1%     8   5       NO
   wrd1  DPC     iec        1%     6   5       YES
   

2. The screen set being changed 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 Database Administration - SS7 User's Guide and change the scrn parameter to reference another screen set, or to none to remove the reference to the screen set.

   Note:

   If a new gateway screening stop action set will not be assigned to the screen set being changed, skip step 3 and go to step 4.
3. Display the gateway screening stop action sets in the database with the rtrv-gws-actset command.

   This is an example of the possible output.

   rlghncxa03w 06-10-25 15:26:30 GMT EAGLE5 36.0.0
   ACT  ACT    ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT

   6    cncfrd cncf rdct 
   7    cpcfrd copy cncf rdct
   
   GWS action set table is (7 of 16) 44% full
   

   If the required gateway screening stop action set is not in the database, go to the Configuring Gateway Screening Stop Action Sets procedure and configure the required gateway screening stop action set.

   Note:

   If theNSFI of the screen set being changed in this procedure will beSTOP, or if theNSFI of the screen set is not being changed, skip step 4 and go to step 5.
4. Enter the commands in the Verifying the Gateway Screening Configuration section to verify that the screen that will be specified by the NSFI/NSR parameter combination in step 5 is in the database.

   If the desired screen is not in the database, perform one of the procedures shown in the Gateway Screening Configuration Procedures section to add the desired screen to the database or change an existing screen in the database.

5. Change the attributes of a screen set using the chg-scrset command.

   If a gateway screening stop action is to be assigned to the screen set being changed, enter the chg-scrset command with the nsfi=stop parameter and the actname parameter with the name of a gateway screening stop action set shown in the output of the rtrv-gws-actset command executed in step 2.

   For this example, enter this command.

   chg-scrset:scrn=ls01:nscrn=ls05:nsfi=blkopc:nsr=ls08

   A message similar to the following should appear.

   rlghncxa03w 06-10-25 15:27:30 GMT EAGLE5 36.0.0
   CHG-SCRSET: SCREEN SET AFFECTED - LS01  1% FULL
   CHG-SCRSET: MASP A - COMPLTD
   

6. Verify the changes using the rtrv-scrset command.

   The following is an example of the possible output.

7. 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.
