NonStop DCE

HP NonStop Distributed Computing Environment (DCE) has been enhanced to provide

jacket routines for context-sensitive SERVERCLASS_DIALOG_xxxx_( ) guardian

procedures. DCE already provided the jacket routine for the context-free Pathway

routine SERVERCLASS_SEND_, limited to sending and receiving 32 KB of data. To

send or receive more than 32 KB data to the Pathway server, you need to invoke this

application program interface (API) multiple times. As this API is context-free, the

request might not go to the same server instance in the Pathway server class. To

enable the DCE client to pass more than 32 KB data to the same Pathway server

instance, jacket routines for the context-sensitive SERVERCLASS_DIALOG_xxxx_( )

procedures are now provided. You can use these new jacket routines by calling them

explicitly in your application. With the new routines, the application can send and

receive more than 32 KB of data to the same Pathway Server instance.

DCE has been enhanced with these APIs:

•

DCE_SERVERCLASS_DIALOG_BEGIN_

Initiates the dialog and also sends the first message of the dialog to the server

process in the Pathway server class. This procedure performs an input/output (I/O)

operation. The parameters and semantics of this function are the same as those of

the Guardian SERVERCLASS_DIALOG_BEGIN_ procedure, which is described in

the TS/MP Pathsend and Server Programming Manual.

•

DCE_SERVERCLASS_DIALOG_SEND_

Sends the message within the dialog to the server process in the Pathway server

class. This procedure performs an I/O operation. The parameters and semantics of

this function are the same as those of the Guardian

SERVERCLASS_DIALOG_SEND_ procedure, which is described in the TS/MP

Pathsend and Server Programming Manual.

•

DCE_SERVERCLASS_DIALOG_END_

Ends the dialog corresponding to the dialog ID. This procedure does not perform

an I/O operation.
