Valuable BAU OEM reports – some examples

A well configured OEM 12c (or any previous version of your choice) is a fantastic enterprise tool and the reporting capabilities are a major asset.

I am going to share three examples of reports we use and find valuable and if anybody has any  other good ideas I am happy  to hear about them.

I don’t think I wrote any of them but I almost certainly identified the requirement and instigated the creation of each report. I have masked out obvious details so the screen shots do look messy.

In a previous post about nproc limit, I wrote that I had to investigate the nproc limit with the number of threads because my Oracle 12c EM agent was having thousands of threads. This post is a short feedback about this issue and the way I have found the root cause. It concerns the enterprise manager agent 12c on Grid Infrasctructure >=

Rman Archive backup failing with RMAN-03002, RMAN-06059, ORA-19625 in Rac

As member of the  team every so many days I am part of hot line , taking care of Tickets and indeed being the (hopefully friendly) voice in your ear when  you call  the  hot line number of Oracle team at the Company.

I love to read Oracle related blogs, forum posts and mailing lists much more often than books. Why? Because there many Oracle DBA’s and developers share their experiences, problems, "best practices",... which are very valuable to me.

It's great that we have so big and active Oracle community.

Today I noticed mail from Oracle-L list where someone asked for help with recovery after overwriting production controlfiles. Check Oracle-L for more info.

Interesting SLOB Use Cases – Part I. Studying ZFS Fragmentation. Introducing Bart Sjerps.

This is the first installment in a series of posts I’m launching to share interesting use cases for SLOB. I have several installments teed up but to put a spin on things I’m going to hit two birds with one stone in this installment. The first bird I’ll hit is to introduce a friend and colleague, Bart Sjerps, who I just added to my blogroll. The other bird in my cross-hairs is this interesting post Bart wrote some time back that covers a study of ZFS fragmentation using SLOB.
