I am working on upgrading a Multitenant environment from Oracle 12.1.0.2 to Oracle 19c. I have 40 PDBs supporting all sorts of dev and test environments. We typically upgrade a few dev databases first and then follow with test databases before upgrading production. When production is upgraded, we like to keep a few dev databases …

Oracle Documentation

Oracle has changed their documentation, making it much harder to find the Oracle Database docs. To access the docs, go to http://docs.oracle.com. From there, you could click on the Database category. As it stands now, the only icons on the doc main page are all cloud-related. It took me a few minutes to figure out …

GI 19c RPM Package Manager Database

I am upgrading an Oracle 18c Grid Infrastructure cluster to the new Oracle 19c version, release for on-premises last week. The OUI pre-requisite checks finds two issues that need my attention.

I was trying to plug a non-CDB into our new Multitenant environment as we make the move to Multitenant. I am going to create a golden image of our production non-CDB and then all dev and test databases will just be clones off the golden image. But first, I need to get the non-CDB plugged …

RAC Sequence Contention

I recently ran into a case where selecting the next value from a sequence was causing contention issues in Oracle RAC.  See this screen shot from Lighty (click on the image to see a larger picture) The wait events will look the same if viewed in Enterprise Manager’s performance screens, which does require one to …

PRVG-2027 Owner of file is inconsistent across nodes

I recently ran into an issue right after I applied the latest/greatest CPU to an Oracle RAC system. Both GI and RAC were patched. The GI alert log showed error messages like: 2018-05-13 22:03:01.121 [SRVM(32264)]CRS-10051: CVU found following errors with Clusterware setup : PRVG-2027 : Owner of file “/pkg/grid/crs12.1.0.2/lib/ libclntsh.so.12.1” is inconsistent across nodes.

Large .patch_storage

I received an alert from Enterprise Manager that one of my production databases was getting low on disk space. I tracked it down to $GRID_HOME/.patch_storage which was consuming 30GB of my 90GB drive. Yikes! The first thing I did was to run the opatch cleanup routine as I documented here back in 2013: http://www.peasland.net/2013/03/21/patch_storage/ Unfortunately, it …

Where are my Patches?

I thought I had posted something like this on my blog previously but I couldn’t find it when I was looking for someone earlier today. So here is the information anew. If my old blog post is not more than just a figment of my imagination, it probably needs updating anyway. 🙂 How do I …
