31.If an administration server running machine got crashed, how will you restart the server with same configuration on new machine?

• Oracle WebLogic Server allows the creation of a backup of the server as follows:
• Install Oracle WebLogic Server on a backup machine.
• Copy the application files to a backup machine.
• Copy the configuration files to a backup machine.
• Restart the Administration Server on a new machine.
• The new Administration Server contacts the Managed Servers and informs them that it is running on a new IP address.

32.How can you run Multiple Weblogic server instances in a same physical machine?

• You can run multiple instances of WLS using different configurations on the same physical machine at the same time by either:
• Assigning multiple IP addresses to a machine (multihoming) and defining each server to use a unique IP address
• Specifying the same IP address but using different listen ports
• A multihomed machine:
• Is a machine with multiple IP addresses
• Can run a different WLS instance that is bound to each IP address
• Can be used to configure a cluster on a single machine

33.How will you create Domain Template? Explain briefly?

• A domain template defines the full set of resources within a domain.
• Oracle provides sample templates for creating any platform domain.
• There are three ways to create domain templates:
• WLST offline command line tool
• pack command
• Domain Template Builder (config_builder.sh under WL_HOME/common/bin)
• Use the Domain Template Builder to create a domain template or an extension template.
