The blog discuss about the technical approach on distributing domain files among distributed WebLogic domain infrastructure , means where multiple machines are installed with same WebLogic version installation but have to share the same domain to be used in distributed infrastructure. 

Lets consider we have 2 machine mach1 and mach2 installed with WebLogic Server. 

Machine1 (mach01) :

• Weblogic Server Installed
• Managed Servers (mach_ms1, mach_ms2)
• Domain: dev_soadomain

Machine2 (mach02) :

• Weblogic Server Installed
• Managed Servers (mach_ms3, mach_ms4)

Now , our requirement is to have machine2 to be part of the same domain dev_soadomain created in machine1 to be part of the clustered WebLogic domain

Distribute domain files to another WebLogic Server using pack and unpack

• Log into Machine1 Weblogic Server Admin User
• Navigate to WebLogic domain folder

[wls@mach01]$ cd $WL_HOME/common/bin

• Run the below given command to pack the WebLogic domain file from machine1 (mach01)

[wls@mach01]$ ./pack.sh -domain=$DOMAIN_HOME-template=$WL_HOME/
common/templates/domains/DEV_SOADOMAIN_template.jar -template_
name=DEV_SOADOMAIN –managed=true

• A file is created at $WL_HOME/common/templates/domains/DEV_SOADOMAIN_template.jar

• Log into Machine2 Weblogic Server Admin User
• Naviage to weblogic domain folder
• Copy the DEV_SOADOMAIN_template.jar from machine1(mach01) to machine2(mach02)

[wls@mach02]$ scp wls@mach01:$WL_HOME/common/templates/domains/
DEV_SOADOMAIN_template.jar $WL_HOME/common/templates/domains/

• Unpack the DEV_SOADOMAIN_template.jar in machine2(mach02) domain folder

[wls@mach02]$ cd $WL_HOME/common/bin
[wls@mach02]$ ./unpack.sh -template=$WL_HOME/common/templates/
domains/DEV_SOADOMAIN_template.jar –domain=$DOMAIN_HOME

• An entry to the DEV_SOADOMAIN domain will automatically be added to the nodemanager.properties file

Distribute domain files to another WebLogic Server manually

• Domain Directory in machine1

DOMAIN_HOME = oracle/Middleware/user_projects/domains/DEV_SOADOMAIN

• Log into Machine2 Weblogic Server Admin User
• Create the Domain Directory with the same name as in machine1

[wls@mach02]$ mkdir –p $DOMAIN_HOME

Copy the Domain files from machine1 to machine2

[wls@mach02]$ scp –rp wls@mach01:$DOMAIN_HOME $DOMAIN_HOME/..

Edit the e nodemanager.domains in machine1 and make the entry

[wls@mach01]$ vi $WL_HOME/common/nodemanager/nodemanager.domains
DEV_SOADOMAIN=/oracle/Middleware/user_projects/domains/DEV_SOADOMAIN/
