- I'm soliciting for ideas and comments on a Unix-based notification
- system.
-
- I have a potential appliation where I would like to notify distributed
- client processes (LAN) that a table(s) was modified in a Sybase database.
-
- I'd like to not use OpenClient at this point if at all possible.
-
- My initial thought is to write a master process that polls a
- "modifications" table (perhaps created via trigger(s)) that tracks what
- was modified and then looking up in a "subscriber" table to see who to
- notify. Then, if needed, send some data via a socket (I'm assuming all
- SPARC machines) to the appropriate subscribers.
-
- Another thought would be to front-end all the queries and, upon
- successful table modification, directly notify any clients (again
- through sockets). This alternative would seem to have performance
- ramifications.
-
- I'd appreciate any comments that any of you might have,
-
- Frank G.
