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...)
This morning I was working on an Oracle Management Repository (OMR) for a test Enterprise Manager that is used by a few consultants I work with. When I logged into the box, I found that the OMR was down. When I went to start the database, I was greeted with ORA-01172 and ORA-01151.
These errors basically say:
ORA-01172 – recovery of thread % stuck at block % of file %
ORA-01151 – use media recovery (more...)
As I’ve been working with the beta of GoldenGate Studio 12c, I have tried to do simple things to see what will break and what is needed to make the process work. One of the things that I lilke about the studio is that prior to creating any solutions, mappings or projects, you can define what databases and GoldenGate instances will be used during the design process. What I want to show you in this (more...)
If you work with Oracle GoldenGate long enough, you will eventually have to setup against a Microsoft SQL Server. Being that GoldenGate is a heterogeneous application, this isn’t a problem; however there are small differences. One such difference is how the exact/replicat will connect to the MS SQL Database.
In an Oracle-to-Oracle configuration, you would just use a command line the following from the command line:
GGSCI> dblogin useridalias [ alias name]
GGSCI> dblogin (more...)
In doing some testing with Oracle GoldenGate Studio, I decided to create a test solution that can be moved from studio-to-studio. In order to move the test solution from studio-to-studio, it has to be exported first. This post will be about how to export a solution so it can be archived or shipped to a co-worker.
To export a solution, you will start in the Projects window. After opening the project, you will see a (more...)
Oracle GoldenGate 12c (18.104.22.168.0) has changed the information that is stored in the trail files. All the standard information is still there. What Oracle changed has to do with the meta data that is used to define a table.
Note: If you want a understand how to use log dump and general trail information, look here.
Prior to 22.214.171.124.0 release of Oracle GoldenGate, if the column order (more...)
With the announcement of Oracle GoldenGate 12c (126.96.36.199.0) at Oracle Open World this year, I was interested in hearing that Oracle has finally integrated the heartbeat process into the core functionality of GoldenGate. Setting up the heartbeat is always a fun thing to do with GoldenGate and I had hoped that this move to integrated it would bring benefits with it. To my dismay, I’m a little underwhelmed with the heartbeat (more...)
With the announcement of Oracle GoldenGate Studio at OOW this year, there has been a good bit of interest in what is can do for any Oracle GoldenGate environment. The basics of this new design tool is that it will allow the end user to quickly build out GoldenGate architectures and mappings; however, before you can build the architectures and mappings there needs to be a repository to store this information.
The Oracle GoldenGate Studio (more...)
