Distributed Transactions and EM12c Page Performance

While presenting at HotSos in Dallas, Tx, an attendee, (thank you Wenju! :)) asked how page performance issues could be identified when the call was being made remotely and not from the Oracle Management  Repository, (OMR) using the Page Performance console within Cloud Control. This is a very good question and although not straight forward, […]

Let’s Talk Database Replay- Part I

Database Replay is a feature in EM12c that a lot of folks are unfamiliar with, but once they learn about it, well, now then they figure out how valuable it really is.  Where the ADDM Comparison Report comes in really handy when you want to see what changed, think about how much more value there […]

How to Use an ASH Report and Why

Active Session History, (ASH) reports are one of my favorite when investigating a performance issue.  The biggest challenge I think that faces many administrators is to know when to turn to an ASH report and how to use the report to diagnose an issue.

Working With AWR Reports From EM12c

I’ve had a recent request to write an update on working with AWR reports, so as promised, here it is! The Automatic Workload Repository The Automatic Workload Repository, (AWR) was one of the best enhancements to Oracle back in release 10g.  There was quite a goal put in front of the development group when they […]

AWR Warehouse and SYSDBA

I’ve had a few folks ask me a similar question about the AWR Warehouse, occuring numerous times this week. “How can I limit what the user of the AWR Warehouse can view in the AWR Warehouse?” “How can I add source databases to the AWR Warehouse without DBA privileges?” This topic bridges into the area […]

Why Automate Target Patching with Enterprise Manager 12c

Every job comes with tasks that no one likes to perform and database administration is no exception.  Patching is one of those necessary tasks that must be performed and when we are expected to do more with less everyday, the demands of patching another host, another agent, another application is often a task that no […]

EM12c Management Agent, OutOfMemoryError and Ulimits

While enjoying the lovely Liverpool, UK weather at Tech14 with UKOUG, (just kidding about that weather part and apologies to the poor guy who asked me the origin of “Kevlar” which in my pained, sleep-deprived state I answered with a strange, long-winded response…. :)) a customer contacted me in regards to a challenge he was […]

OMS and OMR Performance- Part III, Metrics Page

Before heading off to UKOUG’s Tech 14 conference, thought I would jump back from the Agents performance page and look into the very important page in the Oracle Management Service, (OMS) and Oracle Management Repository, (OMR) regarding metrics.  Standard metrics collection is demanding in itself, so when we add plugins, metric extensions and manual metric […]
