Remove Existing Computers

Remove a failed or redundant computer from a cluster. The computer, Managed Server, Node Manager, and system components are removed from the domain. Service instances are unregistered, and ports are deallocated.

Assumptions

  • You must have appropriate file system (offline) permissions, or Oracle WebLogic Server Administrator (online) permissions.

  • The system can be running (online) or stopped (offline).

  • You can't remove the primary computer.

  • You can add or remove service instance registrations.

  • No binary files, configuration files, or state information, are deleted from the computer that you remove.

  • There is no loss of service when you use the stop command.

  • There is no loss of availability when you use the stop command, unless the user forces it.

  • Control of the Cluster Controller, Scheduler, and BI Server is unchanged.

Prerequisites

If possible, you should stop active components on the target computer before removing it using the status.sh and stop.sh scripts. See Use Commands to Start, Stop, and View Status of Processes.

  1. Use the deleteBIMachine WLST command to remove components created by cloneBIMachine or clone_bi_machine.sh in:

    ORACLE_HOME/oracle_common/common/bin/wlst.sh

    For example:

    deleteBIMachine(DOMAIN_HOME, machineName)

    Or run the delete_bi_machine.sh script in:

    DOMAIN_HOME/bitools/bin/delete_bi_machine.sh|cmd machineName

    The command displays the removed computer name.
