Listing BDWN Command Line Syntax for Requesters

BDWN [ALL | REQUESTER I | REQUESTER]

BDWN

Shuts down all Handlers or all Requesters or both. It also frees shared memory used by the Requesters associated with each logical machine ID (LMID). You can specify optional parameters with the BDWN transaction to shut down Handlers or Requesters immediately or after processing of all requests has completed. The default is ALL.

ALL

Shuts down all Handlers and Requesters gracefully allowing them to complete all processing of all requests that were received before the execution of the BDWN transaction. Specifying ALL also frees any shared memory.

This is the default for BDWN.

REQUESTER I

Shuts down all Requesters immediately and frees memory associated with each LMID. This parameter does not shut down any Handlers.

REQUESTER

Shuts down all Requesters gracefully allowing them to complete all processing off all requests that were received before the execution of the BDWN transaction. It also frees memory associated with each LMID. This parameter does not shut down any Handlers.
