USING XWB DEFERRED RPC

[[RPC_HELP_XWB_DEFERRED_RPC|XWB DEFERRED RPC]] is used to pass the name of the RPC to be run in deferred mode and any parameters associated with the deferred RPC. In response to this RPC the VistA M Server returns a [[RPC_HELP_XWB_DEFERRED_HANDLE|HANDLE]] to the user application. At this point other Broker calls can commence while the job runs in the background.

[[RPC_HELP_XWB_DEFERRED_STATUS|XWB DEFERRED STATUS]] allows the application to check the local VistA M Server for the presence of results from the deferred RPC. This RPC passes the [[RPC_HELP_XWB_DEFERRED_HANDLE|HANDLE]] to the local server and receives back the status of the remote RPC.

[[RPC_HELP_XWB_DEFERRED_GETDATA|XWB DEFERRED GETDATA]] is the vehicle for retrieving the results from the remote RPC after the status check indicates that the data has returned to the local VistA M Server. The RPC passes the [[RPC_HELP_XWB_DEFERRED_HANDLE|HANDLE]] and receives back an array with whatever data has been returned by the deferred RPC.

[[RPC_HELP_XWB_DEFERRED_CLEAR|XWB DEFERRED CLEAR]] must be used to clear the data under the [[RPC_HELP_XWB_DEFERRED_HANDLE|HANDLE]] in the ^XTMP Global.

Applications using XWB DEFERRED RPC should use [[RPC_HELP_XWB_DEFERRED_CLEARALL|XWB DEFERRED CLEARALL]] on application close to clear all known data associated with the job on the VistA M Server.
