I've got an odd question for ya: are there problems associated with constantly connecting to/disconnecting from a session during the course of a day?

The situation: we are allowed only a single connection to a remote mainframe for each workstation; each user now has at least two programs that need to retrieve data from that session, and the user needs to be able to use it also.

I've just done a quick test to see whether the program could successfully connect/disconnect/re-connect the session, and it worked like a charm so what I'm considering now is having each program connect/retrieve/disconnect, connect/update/disconnect - leaving the session available for another program to connect.

Doing it this way, there's no likelihood of the two programs competing for a connection - but this is a cycle that'll happen hundreds of times per day, per user, and that's where my concern lies.

Has anybody tried this? Had success/failure with it?

Hi,

I run several applications where I open and connect to an Extra session running a TN3270 emulator. I have never tried to run more than one application at a time.

If I were asked to do that, I think that my approch might be that when an application's procedure started, to FIRST check the OIA connection status or check to see if the cursor is at rest on the initial screen for at least 5 seconds. I always begin any transaction series on our initial entry screen, after login is complete.

Just my 2 cents, plus a buck and a half'll get ya cup o' coffee.

Sorry it's taken so long to get back. We just went through a network changeover. Loads 'o fun!

Since the user has to use the session also, I got used to checking which screen the session was on before beginning a transaction.

I'd noticed the OIA functions, but haven't yet tried them. Would there be a benifit?

In our situation each program reacts to user input, (interactive retrieval/updates), so I shouldn't have to worry about the cursor being in motion.
