Jim, If you don't want to turn it off , you may want to limit the amount of storage that is used for minidisk cache. You can do this by using the following commands .........
cp set mdcache storage 0M 2M (this would limit central mdcache to 2M) cp set mdcache xstor 0M 2M (this would limit xstor mdcache to 2M) cp set mdcache off (this turns off mdcache) What limits should you use? That you will have to play with to see what is best for your environment. Remember that mdcache is write thru cache, so unless your application is doing allot of reads your not using it anyway. John My VM guy here is saying that he read some place that having mini-disk cache turned on for mini-disk volumes used by linux for system disk is a good thing. My position has always been that Linux is caching what VM is caching and it's a double fault. Since I'm not the VM guru (and neither is he really, been doing VM here for just over a year) I don't have any traction in getting this changed. >From what I can see I'm caching 550 megs in Central stor on average and 163 or so megs to expanded. The only disks I could get him to turn off caching for was my linux swap volumes. So who is right? Isn't it correct that turning off mini-disk caching for the linux volumes is the recommended method? Wouldn't that free up memory othwise used by VM for the caching? We're getting very close to making VM page on a consistent basis. We're running 6 websphere servers in 6 gigs real 1 gig expanded (I know it should be more. We just don't have it). I'm also in a position where I have to recommend how much memory and CPU I think we're going to need over the next three years, but nobody wants to tell me how much more load they want to send me so thats hard to say. Anyway, if theres cold hard fact that can be waved in eithe rmy face or his to settle this, I'd appreciate any input.
