How To: Access the Ops Center Database

Ops Center uses an Oracle Database to store product data. Normally you'll use the Ops Center UI and won't access the database directly, but it can occasionally be useful to see the database contents directly.

We've put together a How-To that explains how to view the database directly. You can make this connection either using Oracle SQL Developer, or from the command line using SQL*Plus. The How-To walks you through both procedures.

P2V: A Detailed Procedure

We had a post not too long ago about physical to virtual migration in Ops Center. It outlined the broad steps involved in performing P2V by taking a flash archive of a physical system and then provisioning a virtual system using that FLAR.

Well, over on to the Enterprise Manager blog, Rodney Lindner put together a detailed post about doing P2V migration with Oracle Solaris Zones. He goes into great detail, with plenty of examples and screenshots. If you're planning on giving P2V a try, you should definitely have a look.

Rodney also did a webex session that covered the procedure; you can find a recording of that session here.

Provisioning Oracle Solaris 11

I've seen some questions about provisioning Oracle Solaris 11. They boil down to this:

"Is it possible to provision both Oracle Solaris 11 and 11.1 onto managed systems from one Ops Center installation?"

Yes, this is possible. There are two ways to do it.

The first way is to have your MSR use Oracle Solaris 11.1, and then have two Proxy Controllers, the first with Oracle Solaris 11 and the second with Oracle Solaris 11.1. The first Proxy Controller will provision Oracle Solaris 11, while the second will provision the latest Oracle Solaris 11.1. This section in the release notes discusses this in more detail.

The other method is to keep your MSR and your Proxy Controllers using Oracle Solaris 11. Then, once the OS is provisioned, use IPS to update the OS to Oracle Solaris 11.1. This requires that each system be updated individually, but it does let you choose which SRU you want.

P2V in Ops Center

I saw a question about physical to virtual migration:

"Does Ops Center have any capabilities that will facilitate the physical to virtual process?"

You can do P2V using Ops Center, but it's not a single-wizard process, and it'll take a bit of tinkering. Basically, you take a flash archive (FLAR) of an existing system, import it, then deploy a host, ldom, or branded zone based on that FLAR. Here's the process in more detail, using an LDom:

  1. Make sure that the source system's OS can run in the intended virtualization technology. LDoms can't support guests using Oracle Solaris 10 6/06, for instance, so you'd have to update the OS before you could virtualize it.
  2. Take a FLAR of the OS.
  3. Upload the FLAR into the Enterprise Controller library.
  4. Create an OS provisioning profile for the FLAR.
  5. Create an LDom profile.
  6. Create a Configure and Install Logical Domains plan that runs the LDom profile and the OS provisioning profile.
  7. Go to the Control Domain or Server Pool in Ops Center and click Create Logical Domains to run the plan.

The Configuring and Installing Logical Domains How-To walks you through steps 4 through 7.

This gives you a virtualized version of the existing OS. Bear in mind that each operating system might have idiosyncracies that need to be fixed, such as placation network changes, physical card access, or changes to volume manger setup. If you run into these issues you can fix them before taking the FLAR or unpack and edit the FLAR using scripts.
