Changes In Attitude

It's these changes in attitude, changes in latitude
Nothing remains quite the same
For all of our running and all of our cunning
If we didn't laugh, we would all go insane

The road ahead for WebLogic 12c

Before we can describe all the new features of WebLogic 12.1.3 & 12.1.4 and compare this to the 12.1.2 version we should first take a look at the 10.3.6 version. WebLogic 10.3.6 is still the latest 11g version but Oracle (more...)

WebLogic Server and entropy

After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.

Overview

Entropy pool

In computing you often need random numbers. They are used for encrypting stuff but (more...)

Using opatch to list valid FMW Homes to apply a patch to

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 (more...)

Bash script for installing WebLogic Server PSU patches via BSU

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.

The script is using BEA Smart Update so it is for WebLogic Server 12.1.1 and older. (more...)

WebLogic Server – Using JDBC TLOG Store

From WebLogic Server 10.3.6 and onwards it is possible to store JTA transaction logs (TLOG) in a database persistent store instead of in a file store.

Overview

Bash script for listing running WebLogic Servers and Node Managers

If you have many domains running on the same Linux server it can be difficult to see what is running and what is not. I have created a Bash script that lists all WebLogic Server and Node Manager processes.

I have tested it on Red Hat 5 and 6.

Here (more...)

WebLogic Server – Max Restarts Within Interval

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...)

Review: "Oracle WebLogic Server 12c – Advanced Administration Cookbook" by Dalton Iwazaki

Another book crossed my desk. Following the latest hype around newly WebLogic Server release and Frank Munz's book there is another "recipe" driven administration book from Packt Publishing available. It was published in June this year and contains 60 advanced recipes to configure, troubleshoot and tune Oracle WebLogic Server.

Abstract

Upgrading WebLogic domains

I noticed that in WebLogic 12.1.2 the old domain Upgrade Wizard has been replaced by a new Reconfiguration Wizard.

I have upgraded WebLogic many times, but I have never upgraded a domain.

If you upgrade WebLogic within a major release e.g. 10.3.5 => 10.3. (more...)

WebLogic Server configuration backup

The WebLogic server stores its configuration in files in the DOMAIN_HOME/config directory. The main file being config.xml.

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...)

Custom Jersey WADL generation

I had a situation where the auto generated WADL did not match with my Rest services. The first difference was that the response is presented as an object instead of a collection of objects and the second one is that it could not handle JSONWithPadding as response.  Because I use (more...)

Coherence 12.1.2 Rest application build with OEPE

With WebLogic 12.1.2 Oracle also released a new version of Coherence and OEPE. The 12.1.2 release contains many new Coherence features like WebLogic Managed Coherence Servers and Coherence Grid Archive ( GAR ) which can be included in an normal EAR. Coherence also has some nice (more...)

FMW 12.1.2 – beahomelist, Central Inventory, Registry and Distributions

beahomelist

In previous versions of the WebLogic server an beahomelist file was created that contained the paths to the installations aka. the Middleware home’s.

Location:
(UNIX) user_home/bea/beahomelist
(Windows) C:\bea\beahomelist

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...)

JAX-WS SOAP over JMS

With WebLogic 12.1.2 Oracle now also supports JAX-WS SOAP over JMS. Before 12.1.2 we had to use JAX-RPC and without any JDeveloper support. We need to use ANT to generate all the web service code. See this blogpost for all the details. In this blogpost I (more...)

Review: "Oracle WebLogic Server 12c – Distinctive Recipes" by Frank Munz

It has been some time since I last read a book about WebLogic. Also the coverage here on the blog has been a little weak in the last few years. Both due to various reasons I can not really talk about. Anyway I still enjoy working with this server and (more...)

Custom OSB Reporting Provider

With the OSB Report Action we can add some tracing and logging to an OSB Proxy, this works OK especially when you add some Report keys for single Proxy projects but when you have projects with many Proxies who are invoking other JMS or Local Proxies than the default reporting (more...)

Look into your JVM with VisualVM

If you want some more information about your JVM, for example your integrated WLS. There is a very easy tool to use, it’s called VisualVM. You can download it from visualvm.java.net. Extract the .zip file and run the \bin\visualvm.exe.

Once the application is started, on the left (more...)
