Oracle Aesthete: WLS - Creating Horizontal clustering of Managed Servers

Weblogic Server 12.2.1.4

Creating Horizontal WLS cluster for Load Balancing

STEP 1: WLSNODE1

1.1 Install JDK. I have installed JDK8-U191

1.2 Install Weblogic 12.2.1.4

1.3 Configure Domain, continue from the last screenshot. It will launch config wizard automatically

STEP 2: WLSNODE1 – Create a PACK of WLS domain

2.1 – Start Services

· Admin Server

· Node Manager

2.2 – Create a PACK

cd C:\Oracle\Middleware\Oracle_Home\wlserver\common\bin

pack.cmd -domain=c:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain 
-template=c:\WEBLOGIC\base_domain.jar -template_name=base_domain.jar

It created a JAR file under C:\WEBLOGIC. But it gave a warning

WARNING: This is a deprecated script. Please invoke the pack.cmd script under oracle_common/common/bin.
Better to use the latest utility to avoid errors ahead

cd C:\Oracle\Middleware\Oracle_Home\oracle_common\common\bin

pack.cmd -domain=c:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain 
-template=c:\WEBLOGIC\base_domain.jar -template_name=base_domain.jar

2.3 Copy the JAR on wlsnode2 to location c:\WEBLOGIC\base_domain.jar

STEP 3 – CONFIGURE WLSNODE2

3.1 Install JDK – same location as that of wlsnode1

3.2 Install Weblogic – same location as that of wlsnode1

3.3 Please make sure you don’t configure any domain on wlsnode2

STEP 4 – WLSNODE2 UNPACK the domain JAR

cd C:\Oracle\Middleware\Oracle_Home\oracle_common\common\

unpack.cmd -template=C:\WEBLOGIC\base_domain.jar 
-domain=c:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain

<< read template from "C:/WEBLOGIC/base_domain.jar">> succeed: read template from "C:/WEBLOGIC/base_domain.jar"

>> validateConfig "KeyStorePasswords"

>> succeed: validateConfig "KeyStorePasswords"

<< write Domain to "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain"

>> fail: write Domain to "C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain"

UNPACK COMMAND FAILED WITH ERROR: Attribute "Password" is not set for user "weblogic"

Solution < DOCI ID: 2373954.1 >

SOLUTION

unpack.cmd -template=C:\WEBLOGIC\base_domain.jar 
-domain=c:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain 
-user_name=weblogic -password=weblogic123

After UNPACK Completes you can see, BASE_DOMAIN Created under Oracle_home.

STEP 4 – WLSNODE2 Change Node Manager Configuration

4.1 Update nodemanager Listening Address

Navigate to Location user_projects/domains/base_domain/nodemanager

Update nodemanager.properties

Change the nodemanager Listen Address to IP address of WLSNODE2

You can change the PORT of node manager too, if you want.

4.2 Start Node Manager

STEP 5 – WLSNODE2 Enroll Node Manager with Admin server of wlsnode1

cd C:\Oracle\Middleware\Oracle_Home\oracle_common\common\bin

setWLSTEnv.cmd

wlst.cmd

wls:/offline> connect('weblogic','weblogic123','t3://wlsnode1:7001')

wls:/base_domain/serverConfig/>

nmEnroll('C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain',
'C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\nodemanager')
