Pack and Unpack Command in Oracle Weblogic

weblogic

Weblogic Domains containing manage servers can be extended to different servers. To do this, weblogic comes with the pack and unpack tools. The pack command creates a template archive (.jar) 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. The unpack command creates a full domain or a subset of a domain used for a Managed Server domain directory on a remote machine.
