In this post, we configure WebLogic and an in-memory data grid, such
as Coherence and present scripts to start and stop the environment. We
start with creating a Coherence Server (which will be our storage
enabled node in the cluster). You can find the steps required to create a
Coherence Server here.
When the server is created, click on the created server and subsequently on the server start, configuration tab, in order to set the class path and some JVM parameters.
Enter the following properties:
- Java Home: Specify the location of the JDK installation directory such that /bin/java exists, in our example we will use /home/weblogic/jrockit-jdk1.6.0_29-R28.2.2-4.1.0
- Java Vendor: Oracle
- Class Path: /home/weblogic/weblogic12.1.1/installation/coherence_3.7/lib/coherence.jar:
/home/weblogic/weblogic12.1.1/installation/modules/features/weblogic.server
.modules.coherence.server_12.1.1.0.jar:
/home/weblogic/weblogic12.1.1/configuration/applications/base_domain/security/test.jar - Arguments: -jrockit -Xms256m -Xmx256m -XXkeepAreaRatio:25 -Xgc:pausetime -XpauseTarget:200m
-XX:+UseCallProfiling -XX:+UseLargePagesForHeap -Dtangosol.coherence.mode=prod
-Dtangosol.coherence.cacheconfig=security-cache-config.xml -Dtangosol.coherence.management=all
-Dtangosol.coherence.management.remote=true
Above,
we have specified the class path to included coherence.jar and
\weblogic.server.modules.coherence.server_12.1.1.0.jar, which are needed
to make Coherence available. The test.jar contains our Coherence
configuration and serializable classes. These are presented in the post. JBoss RichFaces, Facelets and Coherence on WebLogic.
Note:
The JVM parameters also included Coherence system settings, such as,
-Dtangosol.coherence.mode=prod and
-Dtangosol.coherence.cacheconfig=security-cache-config.xml. With the
first one, we tell Coherence to run with production settings. The second
one defines the cache configuration file to use. Unfortunately, the
configuration provided in a Coherence override is not picked up. Read the full article here.
