opatch apply online on 11.2.0.4

The credit for the patch apply in the post goes to a new friend that wishes to remain anonymous, except that her initials start with KA, and who happens to work at a company in Memphis, TN. Coincidentally, that is where I had been liv. During a recent EM12c project at her company, we were going through the steps to create a 2-node RAC environment. After registering it with Enterprise Manager, and adding the relevant targets (Oracle Homes, Databases, Listeners etc) we tested the connectivity (specifically checking the tablespace usage) to one of the databases and receive an “ORA-01000 maximum open cursors” message.

The open_cursors parameter in the respective database was set to 5000, and there were hardly any connections on it at the time which could explain it. We attempted a local login (from the respective host) as well as a listener based login, both of which were successful. After a quick search on MOS, it turns out there’s a bug which causes queries from Enterprise Manager on 11.2.0.4 Databases: “EM 12c: Querying a List of tablespaces for an 11.2 Oracle Database Results in ORA-1000 Error in Enterprise Manager 12.1.0.3 Cloud Control (Doc ID 1618684.1)”. The solution, according to the MOS note, was to apply Patch 17897511 on the RDBMS home where the 11.2.0.4 instance resides.

Since I’d never tested the online patching process, it seemed like a good time to try it out. I’d recommend reading Jason Arniel’s post here on the subtle “ism’s” of online patching - I found it to be quite useful.

Let’s begin.

 Great! Let’s just make sure that it worked.

And, thats it. After the patch application, we were able to query the tablespace information for all databases running from this home successfully via Enterprise Manager.

Cheers!
