With my previous post on the “All Metrics” page breakdown in Enterprise Manager I talked about the collected, aggregated, and available information on metrics for a given Target type. As we’ve seen, the Metrics Categories are numerous and really depend on the monitored targets. Well, what does that mean? And, how does one find out […]

In my previous post on #em12c Metrics: An Introduction, I wrote briefly on the basics of Enterprise Managers collected metrics, their various location(s) within the Oracle Manager Repository and shared a few queries on how to retrieve and view the data. Today, I’d like to resume the series and explain how the Metrics are accessible […]

Nearly a year ago I wrote about GoldenGate monitoring using a Metric Extension, and then later on expanded upon the creation of a Metric Extension, which I’ve installed and configured at several customer sites where GoldenGate was running on a stand alone server. Over the last few months, several people had approached me on the process, […]

One of the things I’ve been eager to try with the latest ( EM release was to change the repository from a non-CDB to a PDB. There’s a note in the EM documentation that discusses migrating the SYSMAN schema option mentioned here. As a mentionable note, Martin Bach wrote a post on switching the repository […]

With the new release of Enterprise Manager, I upgraded my installation successfully using the superb documentation here. It is however, important to note that the post-steps are also important. For example, upgrading (at the very least) the Management Agent on the OMS host, and de-installation of the old-OMS home. Gokhan Atil wrote a good […]

I’m going to make this a quick post because I just came across this and wanted to document it. The environment is GoldenGate on Linux 64bit, with replication between two 11gR2 Oracle Databases. While attempting to stop an EXTRACT, I receive the error message below: The quick workaround, in most cases, is to simply […]

Today, I had the pleasure of deploying a couple of plugins for Application Management Pack (eBusiness Suite and Siebel) when I came across a nasty error during the actual deployment phase where the OMS is shutdown and restarted. Umm, what the %#$@? When I checked the emctl.log, it seemed to me that the deployment process had […]

While setting up Database as a Service, I came across this particular issue on DB12c while creating a Pluggable database. Now, I am not certain whether this has anything whatsoever to do with the fact that it is on a Direct NFS (dNFS), but the creation fails with the error message below. [oracle@dc01db2a ~]$ tail […]

As part of the Database Lifecycle Management (DBLM) Pack, Database Provisioning in Enterprise Manager is a powerful and quite flexible feature to provision databases. In the past, I have written several articles on Patching and Provisioning (P&P) using the #em12c and today I’d like to add one more to the list. This time, it is […]

At Bobby’s (@dbasolved) insistence, I decided to write this post because it might prove useful for some folks. He mentioned following a note by Jeff Smith (@thatjeffsmith) that he is unable to locate at this time. If you are a VirtualBox user, you obviously have a need to maintain multiple Virtual Machines. You would also […]
