Custom Monitoring Policies

In Ops Center, you can create custom monitoring policies to set different monitoring thresholds for different groups of assets. I got a question about how to implement this:

"I'm trying to create a custom monitoring policy that'll be used for all global zones. So I copied the default one, tweaked a threshold and clicked 'Set as Default Policy'. However, even after checking that option, all of my global zones are still using the old monitoring policy. How do I get them to use the new one?"

So, setting a monitoring policy as the default just means that it'll be used for any new assets of that type. So, in this case, new global zones would use your custom policy, but global zones that already have another policy won't automatically switch. To switch your existing global zones over to your new policy, you need to select them (either individually or in a group) and apply the new policy to them. There's an action to do this in the actions pane.

Moving the DB to a new location

I got a question about the database location:

"Ops Center installs an embedded Oracle database in /var, but we'd like to move it to another directory. Is this possible?"

So, theoretically you could change the location on an embedded database, by stopping the EC and doing some ZFS juggling to move the /var/opt/sun/xvm/oracle directory contents to a new directory and mounting it to /var/opt/sun/xvm/oracle, but there's an easier (and officially supported) way to do this.

The officially supported way is to switch to a customer-managed database. This database can be located anywhere you want, so you can give it as much space as you need.

Backup and Restore issue

I got a question about the backup and restore process for the Enterprise Controller:

"I upgraded my Enterprise Controller from 12.1.3 to 12.1.4 a while back, but I haven't run the 'ecadm backup' command since then. So the only backups I have are from before the upgrade and the automatic one made during the upgrade.

"Well, we just had a crash on our EC system. However, when I try to restore from either of those two backups, it fails, and says that it's looking for the 12.1.3 packages. How do I get this system back up?"

So, in order to restore from a backup file, the Enterprise Controller version needs to be identical. So, the backup from before the upgrade expects 12.1.3, and so does the backup made during the upgrade. (The automatic backup is only made so that, if the upgrade fails, we can roll back to the prior version.)

In this case, you'd have to uninstall 12.1.4, then reinstall 12.1.3, and finally restore from your backup file. The Backup and Recovery chapter explains this process and the requirements.

It's a good general practice to do regular backups so that a system failure doesn't cost you much data, and we also recommend doing a backup after completing an upgrade.

Connecting Ops Center to an Enterprise Management Framework

I got a question about making Ops Center work with other tools:

"My environment uses CA Unicenter. Is there a way for me to forward alerts from Ops Center over to CA Unicenter?"

There are two ways to do this.

One way is to use Halcyon's Neuron Integration, which can take alerts from Ops Center and pass them on to CA Unicenter or other Enterprise Management Frameworks.

Another way is to use Oracle Enterprise Manager Cloud Control to take data from Ops Center and then send it on to CA Service Desk.

1. Make sure that any asset that you want to pass along alerts for is Agent-managed in Ops Center.

2. Use the System Monitoring Plug-in to connect Ops Center to Cloud Control.

3. Use the CA Service Desk Connector to connect Cloud Control to CA Unicenter.

Cloud Control has connectors for a variety of Enterprise Management Frameworks, including BMC Service Desk, IBM Tivoli, and HP Service Manager.
