Step 3. Work with Listener Records

From the Work with Configuration Items menu, select the COMMS_LISTENER_RECS to review these records. The Work with Communications Listener Records screen is displayed.

This screen lists all the listener records stored in the LANSA Communications Extensions routing table.
There is one listener record for each supported communications method.
If a record has been defined for the system, make note of the Connection ID. You can use option 2 to change the connection ID if required.
If a record has not been defined, press F6=Add/Create.
The Add Communication Listener Record screen is displayed.

These input options are required on the Add Listener Record screen:
Communications Method
Specify SOCKET.
Number of Session Jobs to Prestart
Enter the number of session jobs to be prestarted by the listener job. Session jobs are prestarted to reduce the connection time from requesting clients by avoiding the time required by the operating system to start a job. It must be a positive number in the range 1 to 9,999.
Connection Identifier
For SOCKET (TCP/IP), this is the port number at which the listener job will listen for connection requests. If left blank, the default value of 4545 is used. The workstations must be configured to connect to the port number nominated here. If left blank, they will use the default value of 4545.
Cryptographic Algorithm
Specify the cryptographic algorithm used to encrypt transmitted data. It is recommended that you initially use *NONE -No encryption. This is compatible with prior releases of LANSA Communication extension.
Data Compression
Specify YES to allow LANSA Communications Extensions to compress the data before it is transmitted. This is the default value. 
Don't change the default for the following options unless directed to by LANSA:
      Login timeout (seconds)
      TCP_NODELAY TCP/IP socket option
      TCP_KeepAlive TCP/IP socket option
      Check exclusive use of port
