It’s certainly been a while since my last blog post – a little over a year to be precise and it just happens to coincide the beginning of my employment here at Oracle. As with any new job, it takes time to acclimate and I’ve found it an easy transition.I believe it is in part due […]

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 […]

Things I see and learn!

Thoughts from James H. Lui

If you Care a Little More, Things Happen. Bees can be dangerous. Always wear protective clothing when approaching or dealing with bees. Do not approach or handle bees without proper instruction and training.
