After installing Weblogic Server on many machines in order to create a cluster, we need to create a template in our AdminServer, after that, we have to make a template in order to transfer it to the rest of the servers. There are another way to do this, but I’ll leave this for other post.
Create the template
$ ~/Oracle/Middleware/wlserver_10.3/common/bin/pack.sh -managed=false -domain=../maleficarum/ -template=maleficarum.jar -template_name="maleficarum"
Once the template is created, we have to transfer it to the other ManagedServer via ssh, and then, restore the template:
$ ./Oracle/Middleware/wlserver_10.3/common/bin/unpack.sh -template=maleficarum.jar -domain=./Oracle/Middleware/user_projects/domains/maleficarum
After the replication of the template, we have to tart our AdminServer and enroll out managed server using WSLT :
$ cd ~/Oracle/Middleware/wlserver_10.3/common/bin $ ./wlst.sh Initializing WebLogic Scripting Tool (WLST) ... wls:/offline> connect('weblogic','weblogic','t3://adminserver:7001') wls:/maleficarum/serverConfig> nmEnroll('/home/usuario/Oracle/Middleware/user_projects/domains/maleficarum','/home/usuario/Oracle/Middleware/wlserver_10.3/common/nodemanager') Enrolling this machine with the domain directory at /home/usuario/Oracle/Middleware/user_projects/domains/maleficarum ... Successfully enrolled this machine with the domain directory at /home/usuario/Oracle/Middleware/user_projects/domains/maleficarum. exit()
This will registrer out NodeManager in the cluster, and creates all the needed files; As first parameter pass the domain root directory and the second one is the nodemanager location.
$ cd ~/Oracle/Middleware/wlserver_10.3/common/nodemanager $ ./startNodeManager.sh
If we get the error “
Native version is enabled but nodemanager native library could not be loaded“, we can edit the nodemanager.properties file as :
$ cd Oracle/Middleware/wlserver_12.1/common/nodemanager/ $ cat > nodemanager.properties $ NativeVersionEnabled=false
From AdminServer console we now start all servers (domain > environment > servers > ManagedServer1 > control)
