Calc Script runs slow one day and fast the next?

Question

We are on Essbase 11.1.2.1. When we run calc scripts to load our actuals and run some allocation scripts, the difference in running time for the same exact script is very different day to day. One day three hours the next 45 minutes. Our servers are just for Essbase. We are on Windows 2008 R2. Has anyone else run into this or have any idea how we could figure out the reason for this. Thanks.

Answer 1

Thanks.  In that case, I would try to grab the cube statistics - especially number of upper-level and input blocks, compression ratio and fragmentation (in EAS you can only see one of the two fragmentation statistics, 'Average Clustering Ratio', not 'Average Fragmentation Quotient') before each run, just to see if they're varying wildly.  Also, if your calc scripts log summary information (is there a SET MSG command in them?  If not you could try SET MSG SUMMARY) then Essbase will write high-level statistics on how much work was done to the application log.
You can see which cubes are loaded (and consuming memory) in the EAS treeview - if they have a check (tick) mark they are loaded.  But you can also see current activity by right-clicking on the server in the EAS treeview and selecting Edit | Sessions.   That will show whether there are other operations (loads, calcs, reports, restructures etc) occurring at the same time.
If none of the above give any clues and this is a virtual box (or you have SAN storage) you really will need someone who understands your infrastructure to help.
I'm assuming these are BSO cubes, by the way!
