Alan, I'm sure this isn't going to be useful now, but I was away travelling for 15 months and have now returned, so... Yes, we run the DB on an MS-SQL server, also virtualised. We have been running Oracle Db's on physical servers, with more and more databases running in our Ms-SQL environment. Now events have forced us to start moving everything to MS-SQL environment, SQL 2008. Things run ok, you just need to beef up your VMs. For celcat in particular, it's not so heavy (for us) that the DB speed is an issue. Cheers, Dave |
