Checking RPC Availability on a Remote Server
Applications can check the availability of RPCs on a remote VistA M Server. Use:
XWB DIRECT RPC or XWB REMOTE RPC
to pass: XWB IS RPC AVAILABLE or XWB ARE RPCS AVAILABLE
to the remote server.
The Run Context Parameter in XWB IS RPC AVAILABLE or XWB ARE RPCS AVAILABLE should be set to ‘R’ or null to check that the remote VistA M Server will allow RPCs to be run by users not logged into that remote server.
