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.
