RV: Timeout when SERVER is down

RV: Timeout when SERVER is down
Hi,

thanks to all who responded to my question.
We've decided to put a flag in CICS.
When CICS starts, a transaction from PLT will check the connection. If it's
OK it sets the flag to OK and terminates.
All the programs will check the flag. The first one to find the connection
is down will start the transaction in background, which will set the flag
to "NOT OK" and call itself every n minutes to check again. When it finds
the connection is up again, it will set the OK flag and go to sleep.

Kind regards,

Horacio Villa
