I installed an SSAS olap instance and a tabular instance on a cluster. My question isn't about the tabular instance but I'll share why its relavent later....
After installing the OLAP instance I realized that ssas olap folders were pointed to the wrong places. The BackupDir, DataDir, LogDir, and TempDir folders, as seen in the SSAS properties window of the SSAS instance weren't what I wanted and frankly that mistake was mine. So I went and changed the folders inside the SSAS properties window. I believe I changed those folders right by shutting down the instance, copying the files where I wanted them, turning on the instance, telling the instance it had new folders, stopping the instance, deleting the old folders and then restarting the instance and verified the msmdsrv.ini config file was changed by the process correctly. It works. I can process the cubes, change nodes, etc.
I was doing some random compliance work and had to go into the Registry settings for SSAS. When I went there, I noticed an old default folder was saved in the registry. I also noticed the folder that I used for the tabular instance was the folder I intended, which was not the default. I looked at: "HKEY_LOCAL_MACHINE >> Software >> Microsoft >> Microsoft SQL Server >> MSAS12.O >> Setup >> DataDir: O:\Olap\Data"
My question is what is this setting used for? What do the Registry settings control for SSAS?
Should I change it to where the instance is pointed to in the server properties and config file?
Thanks,
Keith
