OBIEE 12c bi_server1 and BI services difference

Question

Hi,

I'm confused what's the difference between the managed server (bi_server1) in Weblogic/EM and the 5 BI services (OBIS1, OBISP1, etc) in EM.  Is the bi_server1 like a container for the 5 BI services?  When do I need to start/stop the bi_server1?  I'm assuming starting/stopping bi_server1 will also start/stop the 5 BI services?

Any insights are appreciated!

Because the job is done by the BI Presentation service.

You can still access static elements like the images etc. But any content requiring the BI Presentation service will not work. The java pages deployed on bi_server1 need the service in the background to be able to show you something.

It's why you always need all the pieces up and running (ok, you can stop the scheduler service and OBIEE will still work, just your schedules agents will not work, but you get the point).

Hi Gianni,

I have a follow up question.  Do you know why when I stop just the BI Presentation Service, the Analytics page won't serve up?  I'd think the Presentation Service won't affect loading of the Analytics page since that is running on bi_server1.

Yes, you can see things like that.

The pages of /analytics (answers) and /xmlpserver (publisher) or even /va (visual analyzer) are server from the managed server and these pages interact with the services in the background and the services interact with each other based on the action you performed.

If you look on your server you see real processes for the services, and when you execute something you see the load increasing on these services based on the task you executed.
