In computing you often need random numbers. They are used for encrypting stuff but also for lots of other things.
All FMW products except the WebLogic server is patched via the opatch tool. From FMW 12.1.2 the WebLogic server is also patched by opatch.
In a FMW installation you can have many Oracle Homes. When you install a patch you need to know which home to apply the patch to.
opatch can help you figure out where to install the patch.
I have a Forms installation that I need to apply a patch (more...)
Patching WebLogic is necessary but not fun. To help out I have created a simple Bash script for installing CPU/PSU patches.
For information about CPU, PSU and SPU patches check this post.

In some situations you have to restart a WebLogic server many times to get something working. A quick and dirty way of restarting a server is to kill the process and let the Node Manager start it up again.
When you kill the process you will see this in the (more...)

The way configuration changes are handled depend on if you are using the domain configuration locking feature. In Production Mode configuration locking is enabled by default and in Development Mode it is (more...)
In previous versions of the WebLogic server an beahomelist file was created that contained the paths to the installations aka. the Middleware home’s.
cat beahomelist /u01/app/oracle/product/fmw;/u01/app/oracle/product/wls;/u01/app/oracle/product/adf;/u01/app/oracle/product/osb
When you deinstall a WebLogic server the path is not removed from beahomelist, but next time you install (more...)
Here one day before deadline, I have entered almost my entire current catalog of presentations for consideration in the Oracle OpenWorld 2013 agenda. One new for this year: “Worst Oracle ADF Project Ever”
If you would like me to speak at one of your events, the following are the presentations (more...)
Oracle has just announced a new Oracle Database Appliance, this time with WebLogic. So if you are looking to move to WebLogic and want a high availability environment, read on.
Like the previous editions of the Oracle Database Appliance, this is a physical 4-U rack mounted box that comes with (more...)
