Using #DB12c PDB as a Repository for #EM12c…. Not so fast!

Last year, I wrote a post on how to setup Oracle Enterprise Manger 12c (12.1.0.3) with Oracle Database 12c (12.1.0.1) and what you could expect.  At the time the configuration was not supported by Oracle and I only did it to see if it could be done.  If you would like to read that post […]

Configure #Oracle #GoldenGate #12c for testing between two or more #db12c PDBs.

Over the last few weeks I’ve been working and traveling a good bit.  Amongst all the travel I’ve been trying to get time to test a few things.  One test I wanted to get done was using Oracle GoldenGate 12c with Oracle Database 12c between Pluggable Databases (in the same instance).   As of today, I’ve […]

Open and Migrate Microsoft Access in Oracle SQL Developer 4

Use DCLI to check #em12c agents on Exadata – all at once

For all the benefits of Oracle Enterprise Manager 12c (OEM), there is one draw back when using OEM with Real Application Clusters or Exadata…. checking the status of the EM Agent on each node.  When a node is bounced, some times the EM Agent does not always restart.  When this happens on a single instance […]

Tuning with ASH Analytics in #em12c

Performance tuning of the Oracle Database has always been a great thing to learn and a valuable skill for any database administer.  In a previous post, I talked about how to use the Active Workload Repository (AWR) and Active Session History (ASH) to performance turn a database.  In this post, I want to take a […]

Create a tablespace in #DB12C

I’ve been messing with Oracle Database 12c (12.1.0.1) today.  As I’ve been working at setting up a few things to test, I realized I need to create a tablespace or two and I didn’t have a post on how to create tablespaces with Oracle Database 12c. Before I can do any testing, I have to […]
