Hello DB2 experts
Is it possible to install in a windows environment the database programs 10.1 on the drive C: but having the database (i.e. the data) on a network drive? The network drive could be a NAS or a Windows share (UNC path) on a different server. The goal would be, to have a lean DB VM with just the database server, where no data is stored.
Is such a szenario advisable?
What about performance, when the data is not stored on C:? Too slow?
Or is it better to have it on the local disk and just copy the daily backup and log files to a NAS?
I assume that the db2 services must have access rights to the UNC path.

Re: Create a database on a network drive2012-12-27T03:56:29ZThis is the accepted answer. This is the accepted answer.Sure, why not? Will it be fast? Probably not (not local DB SSD speeds), but could be fine for many situations.
As usual, it depends upon the sizes of your DBs, how many users/customers are hitting your db, how complicated your queries are, how much of all this can be cached and how much money you have to blow on hardware. Do you have a decent NAS box (RAID)? Gigabit ethernet? Jumbo Frames? NAS would probably be fine for Development and Test Environments (and small/medium scale Production Environments).
Otherwise for Production systems with lots of transactions/users/complex queries, look up Storage Area Networks (SANs), but they're pricey (and uber fast + provide good management options for Sys Admins).
I'm sure there are many others out there who can help you with more information for your Windows Env. NAS DB questions. Might want to try posting on other more heavily read forums?

It is theoretically possible, but not recommended for a number of reasons, and is only supported with a limited number of NAS devices. Check the discussion of the CREATE TABLESPACE statement in the manual for details.
