Administering the Gateways

necessary task, U1 to insert, U2 to update, or U4 to delete. For field definitions, refer to the “The User Connection ACCOUNT Screens” section.

Note: Changes to the User Connection Accounts do not affect Handlers that are currently connected, but only Handlers that connect after the change is made.

Modifying Connections

You can dynamically configure the status of a connection. Using the Update Connection screen (C2), you can enable, disable, or abort the connection for a given LMID. Dynamically configuring the status of a connection has an immediate effect on the corresponding Requesters. For field definitions, refer to the “The Connection Screens” section.

Note: Because the data in the Update Connection screen is transient, setting the LMID status to disable does not persist after the CICS region is shut down and then restarted. The Requester file, however, is persistent.

Deleting Requester LMIDs

Each instance of the Requester is given a logical machine name (LMID). You can give a Requester any unique LMID that is meaningful to you. Every service name is associated with one or more LMIDs. This method allows the Requester to identify which remote machine is responsible for a particular service. You can dynamically delete an LMID using the Update Requester screen (R2). This dynamic change only affect Pre-requesters immediately.

Note: Requesters that are currently running do not read the information in the requester file and are not affected by this dynamic change.

Administering the Gateways

Oracle Tuxedo has a set of tmadmin and dmadmin commands for the administration of the TMA TCP gateways. For detailed information about these commands, refer to the Oracle Tuxedo documentation.
