Abend-AID supports TCP/IP communications from an ISPF session to any Abend-AID viewing server that is configured to support TCP/IP, regardless of the where the viewer is active.

When you customize the viewing server, review the following viewing server parameters for TCP/IP access from Viewing Server PARMLIB Member AAVWALL parameters:

Task 10.9  Configuring TSO/ISPF for TCP/IP

For the TSO/ISPF interface to access an Abend-AID viewing server using TCP/IP, the interface needs to identify the host name and port number for the viewing server. Choose one of the following two methods to accomplish this requirement:

• Shared customization file method
• Direct method.

Shared Customization File Method

The first, and probably the most common, method is for Abend-AID to read the information from a shared customization file. This method requires that an Abend-AID customization file be shared between the LPARs that the user desires to communicate with. The TSO/ISPF interface reads the customization file and displays a table of the active Abend-AID viewing servers supporting TCP/IP. The user can then select which server to access.

To use the shared customization file method, perform the following steps:

1. Copy installation sample library hlq.CTL member $66CLST to a new CLIST. You can rename the CLIST to conform to site standards.
2. Update the new CLIST by changing the COMM(HCI) parameter on the first line to COMM(TCP).
3. Save the updated CLIST.

Executing the updated CLIST enables Abend-AID to read the customization file and present the user with the available viewers. If only one viewer is available, the user can access that viewer immediately.

Direct Method

The second method allows the user to update a CLIST member directly to provide the host name and port number. Because only one host name and port number can be entered into the CLIST, a table of active viewing servers is not displayed. Instead, the user immediately accesses the server when the CLIST is executed.

To use the direct method, perform the following steps:

1. Copy installation sample library (CTL) member $66CLST to a new CLIST. You can rename the CLIST to conform to site standards.
2. Update the new CLIST by changing the COMM(HCI) parameter on the first line to COMM(TCP).
3. Add the following two lines of code after the first line of code:
   1. SET &HOST=hostname, where hostname is the name of system where the Abend-AID viewing server is active.
   2. SET &PORT=portnumber, where portnumber is the port number assigned to that Abend-AID viewing server.

      For example:
      SET &HOST=BMC.COM
SET &PORT=48226

4. Save the updated CLIST.
   Executing the updated CLIST enables Abend-AID to connect to the viewing server associated with the supplied host name and port number.

Multiple TCP/IP Stacks Support

The Abend-AID TCP/IP interface uses the default TCP/IP stack for communication. For sites using multiple TCP/IP stacks, to override the default TCP/IP stack, perform the following steps:

1. Update the CLIST that is being used for TCP/IP access by adding the following line of code:
   SET &TCPJOB=jobname, where jobname is the name TCP/IP job.
   For example:
   SET &TCPJOB=TCPIP01
2. Save the updated CLIST.
