To send an indirect request to the mainframe, a client application issues an RPC that resides on Adaptive Server.
After parsing and pre-processing the request, Adaptive Server sends the request and parameters to TRS for forwarding to a mainframe transaction. When the results return, they follow the same route in reverse.
If you set the TRS DirectPrevent configuration property to yes, TRS rejects all direct calls from client applications, requiring all requests to be sent indirectly. Routing all requests through Adaptive Server allows you to use additional front-end tools and provide additional security checks. Do not use this method if the client submits long-running transactions.
