Timeout Error!

Posted on 1998-11-14
Last Modified: 2008-02-26
Im am accessing a Sybase system 10 database using Visual Basic and ODBC. There are a number of clients in operation.
When performing an Update to the database, the client occasionally times-out and the following message is returned from ODBC.

S1T00:[INTERSOLV][ODBC SQL SERVER DRIVER][SQL SERVER]ct_results():user api layer: internal Client Library error:Read  from the server has timed out."

This only happens when there are a lot of people using the system. When a single person is accesing the database, it all works fine.
Could the server be causing this problem?

It is running on a Solaris Server.

Could this cause the problem?

I would suggest you to run the 2 following commands as root:
ndd -set /dev/tcp tcp_old_urp_interpretation 1
ndd -set /dev/tcp tcp_keepalive_interval 10000

and add it to your /etc/inetinit so if you reboot your system
it will remain set. This will set your keep alive timer long enough at the network level so your packets doesn't get discarded by the system.

Have you checked the max number of user connections allowed?  Maybe that or # of open databases.  You could be hitting up against one of these.  Check em with sp_configure

just a guess

Check with sp_configure with time out option.The reason is there are many process running and the multi-threaded application has to run on your server.So the treads to get the work done as to wait a much longer, so give the time out opption it little bit larger than the previously set value.If this also does not work edit your interface file in which you give the delay time for the server.

Ive already sorted this out...I was opening far too many connections and recordsets without closing them on my client, coupled with sending large amounts of text data. This made the affair very slow, but ive fixed it now, thanks.
