3.2.5 Securing Outbound Connections from CICS to UNIX

For TMA TCP 12.1.3 Gateway and earlier, complete the following steps to enable security for each outbound connection.

1. Specify LMID TYPE=X on the appropriate Requester screen.
2. Enter ACCOUNT and PASSWORD values on the appropriate Requester screen.

   Verify that the parameter values for ACCOUNT and PASSWORD in the Requester screen match the RMTACCT and PASSWORD values in the *FOREIGN section of the TMA TCP gateway in the GWICONFIG file.

   When LMID TYPE=X, the requester program sends the ACCOUNT and PASSWORD to the remote UNIX system on connection initiation.

For the TMA TCP 12.2.2 Gateway and later, complete the following step to enable security for each connection.

1. Specify LMID TYPE=T on the appropriate Requester screen.

   Original user name and password validation for TMA TCP connection validation is obsoleted. The magic number is used instead to enhance the connection validation.

   In addition, if LMID TYPE=X, the transaction fails and throws the error "Invalid LMID Type X for 12.2.2 and latest Tuxedo versions." in the CICS log.
