What does "sp_configure max network packet size" affect? The current connection or the entire server?
If it's the connection, it simply can't work: The commercial app is forked, and has no relation to DBI's connection, so it creates and uses its own connection (though it seems to fail to set the desired size by itself).
It it's the entire server, does the client library assume a certain size or does it asks the server for the current max. packet size?
(And why would you want to change that setting?)

Sooo, in my perl program, I connect to the database with DBD::Sybase, execute a
sp_configure 'max network packet size' and then I system() the
commercial program with the argument -zpkt=whatever I got back.
Occasionally, the program responds with
DB-Lib ERROR: 20201: Packet size of 16384 not supported -- size of
13824 used instead. severity is 1
The program then dies, but that is their problem - it should
disconnect and reconnect properly and I will register te bug with them
My question is this what causes this? One minute 16384 is ok and the
next its not. DBD::Sybase is CT-LIb based and their program is DB-Lib
based. Is that a problem?
