Multiple EBS enviironments on ODA

[wacjob]

Hi Erman,

Question for you.  In any of your environments, do you run multiple EBS environments on a single ODA?  We're looking at purchasing some ODA X7's and was wondering how that would work.   We would want to put the production EBS on an ODA in our prod DC and have another ODA in our DR DC that would have the DR standby for the prod EBS as well as our DEV/TEST/UAT/QA EBS environments.   Our main question then is how the databases for the standby and non-prod EBS environments would live/co-exist on the DR ODA and what the performance would be like?

Any thoughts?

thanks

Hi,

Multiple EBS instances can work on ODA..
I have done this on ODA X5-2 Virtualized env, and didn't encounter any performance issues.
Since, the new gen X6 and X7 ara faster than X5; I believe, the same config will work on them well..
We have capacity on demand on ODA. We also have the ability to assign different cores to different Vms running ODA.

Still, it depends on your EBS load.
A proper sizing may tell it better.

So, you will go with a Virtualized deployment and you will put your databases into the ODA BASE domain, which is the privileged one. As for the apps tier, you will use standard Oracle VM Guests created on top of your virtualized ODA.
You can use the same approach for building your ODA in DR site.
DB will be replicated using dataguard.
Apps will be replicated using rsync or ACFS snapshot replication( this one I didn't try yet :)

You will have the advantage of provisioning the clone machines, when they needed.
You will have the advantage of using capacity on demand.
You will have the advantage of using odacli/oakcli for the management.
You will have Oracle Support with you (from apps to hardware)
And you will have ACFS for taking db snapshots.

Thanks for the info!   Do you know anybody who is using ACFS for their databases and has experience with the ACFS snapshots for cloning?

ACFS snapshots can be used for an additional database backup technique.

However, I didn't see it on any production instances.. I mean ACFS is used in Production sites but ACFS snapshot based backup routines are not so common.. At least not yet.. But it can be used..
