LogDump and Understanding header information in Oracle GoldenGate Trail Files

Replication of data is always a fun thing to look at; What is replicating?!  Discussions around, How do I get data from server/database A to server/database B or even to server/database C are valid questions and are often asked by management.  Often the simple (knee jerk) answer is, just set it up and start replicating.  Although Oracle GoldenGate may be simple (for some architectures) to meet the demands of management and the (more...)

Monitoring Oracle Golden Gate from SQL Developer

Last week I was at Collaborate 14 speaking in two sessions; one of the sessions I had done a couple of times before.  The other session was about the different ways of monitoring Oracle GoldenGate (If you are curious about the presentation it can be found here).  While at the conference I ran the idea of monitoring GoldenGate from SQL Developer by a few peers and there seems to be interest.  (more...)

Monitor Oracle Golden Gate from SQL

One of my presentations at Collaborate 14 this year revolves around how many different ways there are to monitor Oracle Golden Gate.   As I was putting the presentation together, I was listing out the different ways for monitoring. I have covered a few of the ways already in earlier posts.  What I want to show you here is how to execute a simple “info all” command and see the results from (more...)

Speaking at Collaborate 2014

I’m a little behind on my updating my blog with images of conferences where I will be speaking (I’ll get to that later and hopefully fix it).  In the meantime, I wanted to let everyone know that I will be speaking at IOUG Collaborate 2014 this year.  IOUG has decided to hold the conference in Las Vegas, NV.  Should be a fun conference; after all everyone knows the saying “What happens in (more...)

Open and Migrate Microsoft Access in Oracle SQL Developer 4

For many people getting start with databases revolve around using Microsoft Access (MS Access). MS Access is an entry level “database” (if you can call it a database) that Microsoft has been putting out for years. Often people want to move older MS Access “databases” into enterprise databases as they become reliant on the information stored in them. Oracle has recognized this and has enabled Oracle SQL Developer to interact with MS Access and allow (more...)

Oracle Data Guard Switchover via DGMGRL vs. #em12c

When you start to look at high availability and replication of data many people look at either Oracle Data Guard or Oracle GoldenGate.  Personally, I opt for Oracle GoldenGate; however, it is not always the best fit for smaller environments where cost is a concern.  When cost is a concern, Oracle Data Guard is a good choice and can be used with Enterprise (EE)  and Standard (SE) editions of Oracle Database.  There (more...)

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 box or a RAC; normally you would have to check  each node individually and restart the agent.  (more...)

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 look at the Active Session History (ASH) Analytics that can be found in Oracle Enterprise Manager 12c.

Active (more...)

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 setup a few tablespaces for the SLOB testing tool.  Below is how to simply create (more...)

#EM12c Browser Security – Certificate Installation

One thing that bugs me is browser security.  When I access Oracle Enterprise Manager 12c (OEM12c) through a browser and get the certificate error (Image 1), it just pushes my buttons.   Why not ship a valid certificate with OEM12c?  In reality, the problem is not with OEM12c; it is actually with the browser you choose to use.  In my case, I use Google Chrome a lot with OEM12c.  So how (more...)

Upgrade Oracle Enterprise Manager 12c (12.1.0.2) to 12.1.0.3

In order to upgrade out OEM environment from 12.1.0.2 to 12.1.0.3 we need to download the latest version of OEM from either http://otn.oracle.com or from http://edelivery.oracle.com. Once we have the files needed to upgrade, we need to stage them in (more…)
