Hi,
We are running for some months a zeo-based site where clients have a zodbc connection
to mssqlserver. We had&nbsp; defined a big value for the clients cache, but recently we drastically decrease that value due to memory problems.
The problem we are debugging now is that once in a while one of the clients became zombie
and going to a good client and doing the &quot;close zodbc connection&quot; the zombie one start moving ok.
So what is happening here? We think since we decrease the size of our clients cache, activity
in sqlserver is now bigger, so clients request more often sql executions.
We believe there is something wrong having this zodbc object shared by zeo clients where
each one of the clients have a NT ODBC DSN source to the sqlserver.
So question is: is it safe to share the same odbc adapter connection with zeo clients or one should take some special care. We are moving into trying to put each client using each own
zodbc connection. Dont ask me how cause we are going to hit it with a large hammer.
Any comments?
thanx,
Julio Dinis Silva
