Installing Multiple OBIEE 12c instance on the same linux server

Rajesh Dhanapal

Hi All,

I am looking to install second OBIEE 12c instance in the existing linux server, I have done this implementation in OBIEE 11g - multiple obiee instance (2 domains) in the same server. Oracle have provided the documentation for OBIEE 11g - Recommended Installation Scenarios for Oracle Business Intelligence

However I am trying to dig the similar document for OBIEE 12c and its not available. I have seen similar post but want to check in the community, whether someone have done this implementation successfully and it all works fine. Also in terms of OBIEE licensing, if we install another OBIEE instance in the same server (with the same core) will it impact the existing licence. Any advise is highly appreciated.

Best regards,

Rajesh Dhanapal.

OBIEE 12c multiple instances - Red Stack Tech

Rajesh Dhanapal

Any one in the group implemented multiple instance of OBIEE 12c in the same server?

Gianni Ceresa

Multiple installs? Sure, all independent and not sharing anything, no problem for that.

Gianni Ceresa

By the way, joining the party later ...

You apparently can have multiple domains on the same OBIEE install (so same "oracle_home" and multiple configs).

Sample App has that with 2 BI instances.

Gianni Ceresa

Correcting my previous answer ...

Sure SampleApp has 2 domains configured against a single install ...

But when you start it, 2 weblogic Admin server, 2 weblogic managed servers etc.

So double resources used (ram, cpu) even if sharing the same binaries on disk.

Thanks Gianni. I understand in OBIEE 11g you can run multiple OBIEE instance in the same server - 2 domains. However in OBIEE 12c

OBIEE 12c multiple instances - Red Stack Tech

As per this article -

The short answer is no. The first releases of OBIEE 12c do not support multiple instances, only a single instance is permitted.

However we can 2 installations of OBIEE running on the same server, we have 2 sockets with 4 cores and I am not sure whether we will hit massive performance issue if we go ahead with 2 instance in the same server.

Gianni Ceresa

The question is ... why?

Why do you want 2 instances of OBIEE?

You probably (for sure) can have a single one answering the needs of all your users.

The resources which will be highly impacted is more RAM: CPU not much as it's used when something need to be done, but lot of RAM will be used. Depending on the number of users and type of activity they do you can clearly plan at least 32Gb of RAM for 2 instances I would say (that's the minimum : an OBIEE require 8-9Gb just to be started).

Also to be noted that 12c is supposed at some point to have what they called "pluggable BI", which is like multiple BI all together. That's definitely not available now and that's why a domain is limited to 1 instance.

The multiple domains is a different things. As said Sample App does it, it works. The point is more why do you really want this.

Thanks Gianni for your reply. The reason for our requirement is we need to have two different catalogs. We have to customise the GUI for one group and provide the reports and hence I though of multiple instance in the same server, since its not supported in OBIEE 12c. I have to go with this path of installing another OBIEE 12c in the same server to cater the business needs.

Hope it clarifies your question. I am open for any suggestions for this implementation, as I am currently performing the POC. Our existing OBIEE 12 is already having custom style and skin, and now new user group require similar sort of report but they need a different style and skin.

Best regards,

Rajesh Dhanapal.

Can't you manage that by setting a different style at the dashboard level for these users?

Some time ago I saw somewhere an example of an OBIEE setup at Mazda where they had 2 kind of styles: one white and one dark and defined it at the dashboard level. So the users had access to a white or dark OBIEE depending on their permissions.

So far there aren't other options ... the "pluggable BI" concept of 12c is still not available and so if just changing at the dashboard level isn't enough you will need your 2 OBIEE.

Unnecessary since as Gianni said you can actually and easily achieve that by having multiple custom styles/skins which are loaded up depending on which user logs on. Very standard approach and easy to do.
