Adding a New Association to a New Application Server

This procedure is used create a new application server and assign a new association to the application server using the ent-as command.

The ent-as command uses these parameters:

:asname – The name of the new application server. The name of the application server can contain up to 15 alphanumeric characters, with the first character being an alphabetic character. Application server names are not case sensitive.

:aname – The name of the association being assigned to the application server.

The maximum number SCTP association to application server assignments that can be hosted by an IPGWx card (referenced by the lhost parameter of the association) is 50. For example, the IPGWx card currently contains 38 SCTP association to application server assignments. The SCTP association to application server assignments could be one SCTP association assigned to 38 application servers, two SCTP associations assigned to 19 application servers, or any combination of SCTP associations assigned to application servers that add up to 38. The SCTP association to application server assignments can be verified with the rtrv-assoc:lhost=<local host name> and rtrv-as:aname=<association name> commands.

* The EAGLE can contain a maximum of 250 application servers.

The open parameter of the association must be set to no before the association can be assigned to the application server. This can be verified with the rtrv-assoc command.

M2PA associations (adapter=m2pa) cannot be assigned to application servers. Only M3UA (adapter=m3ua) and SUA (adapter=sua) associations can be assigned to application servers. This can be verified in the ADAPTER field in the rtrv-assoc output.

The application server recovery timer (the tr parameter of the chg-as command) for the application server is set by default to 10 milliseconds when an application server is added. The traffic mode (the mode parameter of the chg-as command) for the application server is set by default to LOADSHARE when an application server is added. Perform the Changing an Application Server procedure to change these parameter values.

Canceling the RTRV-AS and RTRV-ASSOC Commands

Because the rtrv-as and rtrv-assoc commands used in this procedure can output information for a long period of time, the rtrv-as and rtrv-assoc commands can be canceled and the output to the terminal stopped. There are three ways that the rtrv-as and rtrv-assoc commands can be canceled.

  • Press the F9 function key on the keyboard at the terminal where the rtrv-as or rtrv-assoc commands were entered.
  • Enter the canc-cmd without the trm parameter at the terminal where the rtrv-as or rtrv-assoc commands were entered.
  • Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-as or rtrv-assoc commands were entered, from another terminal other that the terminal where the rtrv-as or rtrv-assoc commands were entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

  5. Enter the rtrv-card command with the location of the card, from the rtrv-ip-lnk output in 4, that will host the association that will be assigned to the application server. For this example, enter this command.

    rtrv-card:loc=1205

    This is an example of possible output.

    If the application assigned to the card is SS7IPGW or IPGWI, shown in the APPL column, continue the procedure with 6.

    If the application assigned to the card is IPSG, the host assigned to this card cannot be used for the association that will be assigned to the application server. Repeat this procedure from 3 and choose another IP host.

  6. Display the associations assigned to the local host value that will be assigned to the association being configured in this procedure by entering the rtrv-assoc command with the lhost parameter. For this example, enter this command.

    rtrv-assoc:lhost="IPNODE2-1205"

    This is an example of the possible output.

    The maximum number of SCTP association to application server assignments that can be hosted by an IPGWx card (referenced by the lhost parameter of the association) is 50.

    If the number of SCTP association to application server assignments is less than 50, continue the procedure with 8.

    If the number of SCTP association to application server assignments is 50, the local host value cannot be used in this procedure.

    Repeat this procedure from 3 and select another local IP host from the rtrv-ip-host output or perform the Adding an IP Host procedure to add a new local IP host. After the new local IP host name as been added, continue the procedure with 8.

  8. Add the new association by performing the Adding an M3UA or SUA Association procedure.

    The open parameter value for this association must be set to no.

    These are the rules that apply to the association and the application server.
    1. M2PA associations cannot be assigned to an application server.
    2. If the application server is being added in this procedure will be assigned to a routing key containing an rcontext parameter value, the adapter parameter value for the association assigned to this application server can be either M3UA or SUA.
    3. If the application server is being added in this procedure will be assigned to a routing key that does not contain an rcontext parameter value, the adapter parameter value for the association assigned to this application server must be M3UA.
    4. SUA associations and their corresponding application server, can be assigned to only these types of routing keys.
      • Full routing key – DPC/SI=3/SSN
      • Partial routing key – DPC/SI=3
      • Partial routing key – DPC only
      • Partial routing key – SI=3 only
      • Default routing key.
      • The routing key containing the application server with the SUA associations must have an rcontext value assigned to it. If the new application server will not be assigned to one of these types of routing keys, the adapter parameter value of the associations assigned to the application server must be M3UA.
    5. 5. The application of the card containing the signaling link assigned to the association is either SS7IPGW or IPGWI.
  9. Assign the new association to the new application server and add the new application server to the database using the ent-as command. For this example, enter this command

    ent-as:asname=as4:aname=assoc10

    When this command has successfully completed, this message should appear. 

    
rlghncxa03w 06-10-28 09:12:36 GMT EAGLE5 36.0.0
ENT-AS:  MASP A - COMPLTD;
  10. Verify the changes using the rtrv-as command with the application server name and association name specified in 9. For this example, enter this command.

    rtrv-as:asname=as4:aname=assoc10

    This is an example of possible output. 

    
rlghncxa03w 06-10-28 09:12:36 GMT EAGLE5 36.0.0

AS table is (4 of 250) 1% full.

    Note:

    If you do not wish to change theopen parameter value of the association specified in9, continue the procedure with12.
  11. Change the value of the open parameter to yes by specifying the chg-assoc command with the open=yes parameter. For this example, enter this command.

    chg-assoc:aname=assoc10:open=yes

    When this command has successfully completed, this message should appear. 

    
rlghncxa03w 06-10-28 09:12:36 GMT EAGLE5 36.0.0
CHG-ASSOC: MASP A - COMPLTD;
  12. 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.
BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
