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.
- Using the Domain Template Builder:
- Define a domain and replicate it across multiple projects
- Distribute a domain packed with an application that has been developed to run in it
