For some time now, I’ve been creating blog posts that walk you through using some of the Enterprise Manager technology to perform specific tasks. For example, there’s one here on setting up Chargeback in EM 22.214.171.124. I’ve never been really satisfied with the way these blog posts turn out, as to document a step by step process like this takes lots of screenshots and you end up with a post that’s a mile long.
We recently had one of our SQL Server instances experience a very large volume of change. Not suprisingly, the transaction log grew really big and was very close to filling up the disk. I had our SysAdmins add more space to the transaction log disk. The process that generated the large volume of transactions is a one-off process and I wanted to shrink the transaction log and let the SysAdmin take his space back to the storage pool. So I did as any SQL Server DBA might do. I took a backup of the transaction log. After that, I attempted the shrink operation.
It is now possible to use Oracle 12c as a repository database for Enterprise Manager 12c Cloud Control. Oracle 12c is almost 2 years old and the first patch set is almost 1 year old. So its about time in my opinion.
If you are planning on using DB12c for your EM12c repository, then make sure you read Note 1987905.1 for important information on the patches you’ll need to apply.
This post has nothing to do with Oracle or Enterprise Manager at all, so if that’s all you’re interested in you can stop reading now.
In the public cloud parlance, consumers never provision to a specific server, instead they provision to a pool of infrastructure within a geographical region or data center. You would find this pattern in AWS, where you select Availability Zones or in Oracle Cloud, where you select the desired Data Center.
EM12c’s private database cloud follows a similar paradigm. It offers a two tier hierarchy in PaaS Infrastructure Zones, and Software Pools.

Changing ownership of Named Credentials is quick and easy. I’d created a Named Credential under my own OEM account and decided to share it with SYSMAN so we could set it as the Preferred Credential for a certain class of targets across the enterprise.
While logged in as the current owner, traverse down through Setup | Security | Named Credentials to this screen:
In a few weeks I’ll be heading to Las Vegas for a few days of relaxation and fun. Well, really I’ll be working, but it will still be fun!
As always, I’ve got a busy schedule planned. Here’s where you can find me over the week if you’re attending (there will be more but this is what I know now!):
9-12p – Everything I Needed to Know About Enterprise Manager I Learned at COLLABORATE – Hands-on Lab
This should be fun. Three hours w/ myself, Kellyn and Werner. We may not stay on topic, but I can promise you’ll learn something new!
