For awhile now, I’ve been looking at different approaches for automating some of my GoldenGate monitor tasks. Yes, there are tools out there that provide a wide variety of ways for interaction and monitoring of Oracle GoldenGate. However, the problem with Oracle GoldenGate is that you have at least two parts of the equation when interacting or monitoring an environment, i.e. source and target. If you are so lucky to have a multi-master (more...)
Well, it is that time of year again; the streets of San Francisco will be crowded with members of the Oracle community! As everyone in the Oracle community descends onto the bay area, there will be excitement about the things that will be announced this year. Sure a lot of it is going to be about “cloud” and what direction Oracle is taking with their “cloud” strategy. Besides, “cloud” there will be a lot of (more...)
In my post on the differences between ADD TRANDATA and ADD SCHEMATRANDATA, I highlighted the differences between the two ways of adding supplemental logging to tables. One of the things I pointed out was that ADD SCHEMATRANDATA doesn’t add any supplemental log groups (SLG). Without SLGs then how does ADD SCHEMATRANDATA work? That was the question I was left with. So I started digging around to find the answer and I think you may be (more...)
Since I published posts on how to retrieve command history within GGSCI using the Oracle provided commands of “history” and “fc”, I was pinged a couple of times by some friends asking about “rlwrap” usage with GoldenGate. The answer is a simple yes, rlwrap can be used with Oracle GoldenGate.
What exactly is “rlwrap”?
According to the readme file at http://utopia.knoware.nl/~hlub/uck/rlwrap/#rlwrap, rlwrap is a ‘read-one wrapper’. (more...)
Ever get tired of typing the same command over and over again in Oracle GoldenGate GGSCI? Well, Oracle has provided a history recall function into GGSCI, I talked about his in an earlier post. This post on history recall can be found here.
In this post, lets take the command recall and how these commands can be edited. In Oracle GoldenGate 12c, Oracle has provided an GGSCI command called “FC”. The “FC” command is used (more...)
If you are familiar with using Oracle GoldenGate, you know that on the source side of the equation you have to enable supplemental logging and sometimes force logging on the database. I traditionally do both just to make sure that I capture as much as I can into the redo stream from the transactions on the database. For Oracle GoldenGate purposes, this is not the only thing you need to turn on to ensure all (more...)
As I sit here working on performing some GoldenGate migrations to AWS for a client, I’ve been thinking about the glimpse of GoldenGate Cloud Service (GGCS) that was provided to me earlier this week. That glimpse has helped me define what and how GGCS is going to work within the Oracle Cloud space. Ever since this service was announced back at Oracle Open World 2015, I’ve been wanting to get my hands on this cloud (more...)
I’m spending some time building out an Oracle WebLogic/Veridata system at home. This is mostly for testing and general understanding purposes. One of the things I’ve noticed with the WebLogic server requires the username and password before the WebLogic server will start. After providing the name and password, the terminal window has to stay open because, closing it will kill the WebLogic server that is running. This leads to two interesting question and simple resolutions.
Oracle Enterprise Manager 12c is a great tool! Now that 13c is out, it is getting even better. This post however it not really about Oracle Enterprise Manager, rather than a quick and simple health check tool that I’ve put together. With the help of of some really cool co-workers (Carlos Sierra and Mauro Pagano), I’ve put together a small diagnostic tool call EMd360.
EMd360 stands for Enterprise Manager d360. The concept behind (more...)
Oracle Enterprise Manager is a complex piece of software that many organizations are running now. Some organizations set out with a formalized naming standard; some do not. Those who do not ofter end up identifying a naming standard later down the road and then making requests to change the names of the targets being monitored. In order to do this, there are two ways:
1. Delete and rediscover the target and rename at time of (more...)
In order to upgrade out OEM environment from 22.214.171.124 to 126.96.36.199 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…)
