OCDoctor Updated

The OCDoctor is a tool that you can use to gather prerequisite and troubleshooting information about your systems. It's included in Ops Center, but you can also download it from here.

Update 4.38 was just released a couple of days ago. It has some new checks, including checking the remote database tablespace sizes and looking for lockfiles left over from prior upgrades. Also, if you run the doctor with the --update option from an Agent managed system, it'll pull the latest version from the Enterprise Controller. This could be handy if you're in a site with limited connectivity.

The OCDoctor chapter explains some of the things that you can do with the OC Doctor, so take a look and get the latest version. (Note that if you're using Ops Center in connected mode, the latest version is downloaded automatically.)

Communication Between OC and EM

I've seen a few questions about connecting Ops Center and EM Cloud Control monitoring - what permissions are needed to make it work.

Ops Center and EM can share data using the Infrastructure Stack Plug-In. This plug-in lets you view EM processes in the Ops Center UI and Ops Center monitoring and annotations in the EM console, including monitoring for service processors, chassis, server domains, zones, and Oracle VM Server for SPARC domains and guests.

To share data between Ops Center and EM, you create an Ops Center user to interact with the plugin. This user can have any roles you choose, including the read-only role.

Each product has its own set of users and roles. The SYSMAN user can see asset information collected by Ops Center software in the EM console and can launch the Ops Center console, but doesn't have  SYSMAN permissions in Ops Center - they only have the permissions of the user you created for the connection. Similarly, an Ops Center Admin can launch the EM console from Ops Center to view information, but they don't have Admin permissions in the EM console. 

For more information about the plugin, see the Plugin Guide.

Oracle Solaris 11.2 Support

Oracle Solaris 11.2 was released just after Ops Center 12.2.1, and I've seen a few questions about when we'll support it, and to what degree.

The first answer is that Oracle Solaris 11.2 is now supported for most features in Ops Center. You can manage it, install it, update it, create zones on it - basically, anything you can do with Oracle Solaris 11.1, you can also do with Oracle Solaris 11.2.

The caveat to that is that the features introduced with Oracle Solaris 11.2, such as Kernel Zones, are not yet officially supported through Ops Center. We're working hard on adding that support right now.

Using Asset Groups

I got a question about putting assets in groups:

"I'm planning on installing some agents manually on existing systems, and I want to have them put in a specific asset group once they're discovered. I don't see any way to tell the install script to put the asset in a group. How can I add the assets to a group, either through the UI or the CLI?"

There are a few ways.

In the CLI, you can use groups mode, and use this command to add an asset to a group:

attach -n| --gear <asset name> -g| --group <group>

You can also use -U| --uuid <UUID> to specify the asset if you have multiple assets with the same name.

In the UI, you have a couple of options. You can select an asset and click Add Asset to Group to add it to a group you select.

Alternatively, if you're trying to make a group for assets with a specific characteristic, you can specify rules that will automatically add assets to a group based on that characteristic.

CPU Architectures in 12.2.1

I've talked about a few of the enhancements that came in version 12.2.1 over the past few weeks. The last one is a new generic architecture class for newer systems that gives you new migration options for logical domains.

Some new systems - Oracle SPARC T4 servers, Oracle M5 and M6 servers, and Fujitsu M10 servers - have a class1 architecture. When you start a guest domain on one of these systems, Ops Center recognizes the architecture, and you can migrate the guest to systems with other CPU architectures without losing any LDOM capabilities.

Take a look at the Oracle VM Server for SPARC chapter in the Feature Reference Guide for more information about CPU architectures and other Logical Domain configuration options.

Audit Logs in 12.2.1

An increased audit capacity for Ops Center is something that folks have been asking about for a while. In 12.2.1, we added audit logs to provide this capability.

The audit logs are kept on the Enterprise Controller system starting in 12.2.1. They contain records of user logins, changes to user accounts, and job details. The logs require root access on the EC system and can't be edited, so they're a secure means of tracking who's logged in to Ops Center and done what.

The Feature Reference Guide has more information about how to view the audit logs.

LDAP Enhancements in 12.2.1

In Ops Center 12.2 and older versions, there were limitations on how a user pulled from an LDAP could log in to Ops Center - basically, users could only log in using the user name field.

One of the improvements in version 12.2.1 is that an Ops Center Admin can designate other fields, such as email address, name, or member ID, to be used when logging in to Ops Center.

The Admin Guide's section on Users and Roles has more information about adding users from directory servers.

Upgrading to version 12.2.1

Now that Ops Center 12.2.1 is out, I thought I'd give a brief walkthrough of the upgrade process.

The first thing to do if you're planning on upgrading to 12.2.1 is checking the upgrade paths. If you're using an older version of Ops Center, such as 12.1.4, you'll have to upgrade to version 12.2 first. Here's a flowchart that shows the supported upgrade paths:


Once you've figured out your upgrade path, you should check the release notes. They have a list of known issues that could be relevant to your environment. In particular, if you're using version 12.2, there's a patch that you have to apply if you want to upgrade through the UI.

Once you've taken a look at the release notes, the Upgrade Guide will take you through the upgrade itself, with different procedures based on how you're doing your upgrade (through the UI or command line) and what sort of environment you have.

Version 12.2.1 Released

Version 12.2.1 of Ops Center is out today.

There are a number of improvements in this version. The big ones are:

  • Support for discovering x86 64-bit Oracle Sun X4-8 servers through the ILOM SP.
  • Additional options for adding users from an external LDAP, using characteristics like full name or email addresses as Ops Center user names.
  • Audit logs let admins track Ops Center jobs, user logins, and changes to a user's roles.
  • A generic CPU architecture lets you migrate logical domains between systems with different architectures.

We've also made a number of performance enhancements - cutting the start-up times for several parts of Ops Center - and a number of bug fixes. You can find the full listing of what's new here.

For information about upgrading to 12.2.1, take a look at the Upgrade Guide.

If you're on 12.2, you'll need to apply a patch to your environment if you want to upgrade through the UI.  See the Release Notes for more information.

Java versions for Agents

I recently saw a question from the field regarding Agent installation:

"I'm trying to manage a group of servers with Ops Center. They use Java 1.5; is that going to be a problem?"

No, it shouldn't be. The Ops Center Agent uses Java 1.6, but it will install Java 1.6 if it's not already there. Java 1.5 and 1.6 can coexist on your systems. As long as Ops Center can get to Java 1.6 in the default location, it should work fine.

How-To: Configuring NAS Libraries

Server Pools in Ops Center let you group multiple virtualization hosts together and migrate guests between them. For guests to be migratable, though, the storage for the guests must be accessible to all of the hosts.

One way that you can make accessible storage is by configuring a NAS library. The library puts the guest storage in an NFS share that can be accessed by the virtualization hosts, enabling migration.

One of our how-tos, the creatively titled Configuring NAS Libraries how-to, walks you through the steps of configuring a NAS library - creating the NFS share on the storage server, then identifying it and creating the library in Ops Center. There's a workflow that explains when to use the several how-tos related to storage library deployment, as well.

How-To: Using Complex Plans

You can use Ops Center to perform some very complex tasks. For instance, you might use it to provision several operating systems across your environment, with multiple configurations for each OS.

Complex plans let you standardize each part of processes like that, and fit them together in different ways based on your environment's needs. You can create an OS provisioning profile for a specific OS, then create an OS configuration profile for one of the configurations your environment needs, and then put them together in a complex plan. By running the complex plan on the target systems, you ensure that no part of the process is being left out or performed inconsistently.

We've put together a how-to that demonstrates how complex plans work, using an Install Server plan as an example.

How-To: Using System Catalog Reports

If you have an environment with a large number of operating systems, it can be a lot of work to keep track of their versions. You might have update requirements or compatibility issues that apply across your environment, so the ability to get information about one or many OSes and their update levels can be very important.

For Oracle Solaris 10 systems, you can use a System Catalog report to track their patch status and installed OS software:

We put together a how-to that explains how to run the report, and also talks about the things you can do with the report once you've run it, like turning it into a template or an OSP Profile. If you manage Oracle Solaris 10 systems, it's worth a look. The how-to is in the Operate How-To Library, which has quite a few other how-tos about keeping your environment running.

How-To: Discovering a Fujitsu M10 Server

Discovering an asset, whether it's hardware, an OS, or virtualization, is the first step in managing it with Ops Center. Discovery lets Ops Center know what assets are there, and lets it begin to monitor those assets and target them with jobs.

Most assets can be discovered using the discovery procedures in the Feature Reference Guide. However, there are a few types of assets that have quirks that you have to take into account during discovery. Fujitsu M10 Servers, have a few settings that must be configured before you can discover it through the UI. We put together a how-to guide for these systems that explains those quirks, and then walks you through the entire discovery process.

If you're planning on discovering any Fujitsu M10 Servers, this guide has all of the information you'll need. There are also a few other server-specific discovery how-tos in the Deploy library, so take a look.

OVM Server for SPARC Enhancements

Oracle VM Servers for SPARC saw a few improvements in Ops Center 12.2. In addition to brownfield support, we've made a number of enhancements to let you add OVM Servers for SPARC to a Server Pool and enable migration of their guests.

-When you discover an OVMSS Control Domain and manage it with an Ops Center Agent, its guests are automatically discovered as well. The guest metadata is initially put in the local metadata library in the /guests directory, but you can move it from one library to another to enable migration.

-Once you've discovered an OVMSS control domain, you can add it to a server pool, even if it's already configured and running logical domains. Even if live migration between OVMSS systems isn't possible due to CPU incompatibilities, you can still put them in a server pool together and enable guest recovery by configuring the CPU architecture of the guest domain as generic.

-You can mark a guest's storage as shared to indicate that it's available to other managed OVM Server systems with the same back-end name. This lets you use storage not fully managed in an Ops Center library as part of guest migration.

Put together, these enhancements make it much easier to manage and maintain OVMSS guests.
