- I have received several inquiries about the EBF. It seems a lot of having
- the disconnect problem, so I am sending follow up to this group.
-
- We have an 4.8 server on VAX/VMS platform. We have installed EBF989,
- which can kill a sleeping process and clean up the locks. In order
- for this EBF to work, we have to set the "keep-alive" flag
- in our Wallongon TCP/IP. We an end-user turns off his (her) PC,
- TCP/IP's keep alive inquiries get no responds form that PC. After
- two minutes, TCP/IP sends a signal to the server notifying the
- disconnect. Upon receiving the signal, the EBF kills the process
- and cleans up the locks.
-
- A short history. Last April, our production was in in a very bad
- shape due to locks left by the disonnects. We managed to get the
- attention of the Sybase Management (we are so called "critical account").
- A Sybase level III engineer worked with us for several weeks, and
- produced this EBF, which has been very critical to us.
