Weblogic : Migrating Web logic Domains from One Physical machine to another

The Most Simple way of Migrating a Web logic Domain from One Machine to another is using the pack command provided by Web logic.

The pack command creates a template (a .jar archive file) that contains a snapshot of either an entire domain or a subset of a domain. You can use a template that contains a subset of a domain to create a managed server domain directory hierarchy on a remote machine.

By using the pack Command we can create a template file for the existing domain like,

[root@vx111a bin]# ./pack.sh -domain=/root/Oracle/Middleware/user_projects/domains/base_domain -template=/root/Oracle/Middleware/user_projects/domains/base_domain.jar -template_name="my base Domain Template" -log=/root/Oracle/Middleware/user_projects/domains/domain-pack.log

<< read domain from "/root/Oracle/Middleware/user_projects/domains/base_domain"

>> succeed: read domain from "/root/Oracle/Middleware/user_projects/domains/base_domain"

<< write template to "/root/Oracle/Middleware/user_projects/domains/base_domain.jar"

....................................................................................................

>> succeed: write template to "/root/Oracle/Middleware/user_projects/domains/base_domain.jar"

<< close template

>> succeed: close template

These are the details that I used in the above pack command

Domain = base_domain

Template Nmae = base_domain.jar

The pack and unpack commands are available are /root/Oracle/Middleware/wlserver_10.3/common/bin

Now Once the template is created , just copy the template file to the new physical machine which already contains the same version of weblogic software running, go to “/root/Oracle/Middleware/wlserver_10.3/common/bin” and run the unpack command sa,

When you use the unpack command with a domain template, it creates a domain containing all of the application and resource files defined in the template. It also creates necessary start scripts, and certain security and configuration files.

[root@vx111a bin]# ./unpack.sh -template=/root/Oracle/Middleware/user_projects/domains/base_domain.jar -domain=/root/Oracle/Middleware/user_projects/domains/admin_domain -user_name="weblogic" -password="weblogic1" -java_home="%JAVA_HOME%" -server_start_mode="dev" -log=/root/Oracle/Middleware/user_projects/domains/domain-pack1.log

Error: Full path required for "-java_home". Use "-help" to see details.

[root@vx111a bin]# ./unpack.sh -template=/root/Oracle/Middleware/user_projects/domains/base_domain.jar -domain=/root/Oracle/Middleware/user_projects/domains/admin_domain

-user_name="weblogic" -password="weblogic1" -server_start_mode="dev" -log=/root/Oracle/Middleware/user_projects/domains/domain-pack1.log

<< read template from "/root/Oracle/Middleware/user_projects/domains/base_domain.jar"

>> succeed: read template from "/root/Oracle/Middleware/user_projects/domains/base_domain.jar"

<< set config option ServerStartMode to "dev"

>> succeed: set config option ServerStartMode to "dev"

<< find User "weblogic" as u1_CREATE_IF_NOT_EXIST

>> succeed: find User "weblogic" as u1_CREATE_IF_NOT_EXIST

<< set u1_CREATE_IF_NOT_EXIST attribute Password to "********"

>> succeed: set u1_CREATE_IF_NOT_EXIST attribute Password to "********"

<< write Domain to "/root/Oracle/Middleware/user_projects/domains/admin_domain"

...............................................................................................

>> succeed: write Domain to "/root/Oracle/Middleware/user_projects/domains/admin_domain"

<< close template

>> succeed: close template

In the above command , iam going to create

Domain = admin_domain

During the unpack command , I also passed 'username' , 'password' , 'server start mode' e.t.c

Once the unpack command is done , you can see a new domain with the name admin_domain
