OBIEE- Maintenance Mode

OBIEE Interview Question: What is Maintenance Mode? When and how it is used? Will users be able to save reports when it is ON?

Maintenance Mode is used for administration of Presentation Services. When Maintenance Mode is turned ON, users will not be able to save changes in Presentation Catalog- it goes in to a read-only mode at this point. This will make sure that webcat is consistent and no one is making changes to reports or saving new ones while you do your maintenance activities.  

When you as an Administrator/Developer are making changes (updating or migrating reports or archiving (taking backups)) in the Presentation Catalog in online mode, you should turn Maintenance Mode ON.

Maintenance Mode can be toggled/changed/switched from Answers/Analyses Administration page. You should be logged in as an Administrator to toggle Maintenance Mode. Click on Administration from Header Menu:

You can also go to http://{server}:{port}/analytics/saw.dll?Admin

Here on bottom left you will find a section for Maintenance and Troubleshooting. This is where you have Toggle Maintenance Mode link. Just click on this link to turn it ON or OFF.

If a user tries to make changes while Maintenance Mode is ON, she will receive the following error:

"Unable to change edit/view mode: System is in Maintenance Mode. Please try again later."

Note: In clustered mode make sure to Toggle Maintenance Mode in Presentation Services of each computer.

Hope it helps!

Cheers!
