Aug 06, 2007MSSQL monitor not working
I have a pool with one mssql server and I wanted to set up the MSSQL monitor type. The problem is, it doesn't seem to make any mssql connection attempts at all.
I've filled out the username, pwd, db name, send/recieve string, but it seems the check doesn't get executed at all (from tcpdump). If I set the monitor to tcp or tcp_half_open, the pool s alive, if I change it to the MSSQL check, there is no traffic being generated towards the mssql and the check offlines the service..
Any ideas what to do. There is a *debug* option for the monitor and I've found the log in /var/log/MSSQL...
This is the output (but no traffic seen on the interface):

- Deb_Allen_18Historic F5 AccountSounds like you need to install the JDBC driver. See the LTM Manual, Appendix A: Implementing an MSSQL monitor -- Click here
I also just posted a working example to the codeshare -- http://devcentral.f5.com/wiki/default.aspx/AdvDesignConfig/MSSQLMonitor.html (Click here)
Hopefully between the 2, that will get you going.

That was a good point, funny I couldn't find that via F5 search (I did try frst ;-)..
Btw, the manual is (so it seems) for JDBC driver for MSSQL 2000, should that work for MSSQL 2005 as well? Because the JDBC 2005 driver is somewhat different (at least the instructions aren't applicable).. - Jure_Simsic_106

It does work with JDBC MSSQL 2k.
You just have to be careful, because nowdays MS is shipping out JDBC4MMSQL2005 by default..
Thanks - Deb_Allen_18Historic F5 AccountGood to know, thanks for the feedback.
