Hi,

I have an old application that I wanted to convert to C/S.  I have simply
installed the DBSRVR onto the server and configured the Session and Database
components.....and everything seems to work well.

My problem is that occassionally I appear to get a 11276 Error...as this was
originally a non-C/S application I have not got anything special to handle
these type of problems.....with my application being on a LAN I have assumed
that there should not be any occassion when the connection should drop out
(I have KeepConnection set the True for both the Database and Session).

Can any one tell me:
1. Why this problem may occur
2. Any guide on what I should do to handle this type of thing.

Regards
Trevor Keegan

The easiest way to handle this is to simply set the
TDBISAMSession.RemotePing property to True.  As long as you haven't modified
the session timeout setting on the database server, the default
TDBISAMSession.RemotePingInterval property setting will be sufficient (60
seconds).

>TDBISAMSession.RemotePing property to True.

I thought that didn't make an appearance until V4?

Hello Tim,

I cannot find these properties on the TDBISAMSession at all.....any other
advice?

See my post above - Tim's advice relates to the next version of DBISAM.  You need to set something up yourself to keep the connection open. I've never used c/s myself so I don't know how personally but here's a post from 2004

Correct, that workaround is as close as you will get with V3.x. The 'ping'
facility in V4.x was added to enhance functionality in this area.

Thanks a bunch....I guess that the easiest thing then is to call this from within a Timer
event...would that be right?

Sounds good to me.

My apologies, I missed the V3 part in the subject header.  Roy's advice is
correct - just use a timer along with a call to the GetRemoteDateTime and
that will be equivalent to a ping in 4.x.
