Method 2: Start a WebLogic Server Managed Server by using the startManagedWebLogic script:

  • (UNIX) DOMAIN_HOME/bin/ managed_server_name admin_url

  • (Windows) DOMAIN_HOME\bin\startManagedWebLogic.cmd managed_server_name admin_url

When prompted, enter your user name and password.


  • The startup of a Managed Server will typically start the applications that are deployed to it. Therefore, it should not be necessary to manually start applications after the Managed Server startup.
  • The Mobile Security Manager (MSM) servers are not supported in 12c. After restarting the servers, the 11g configurations of MSM servers, like omsm_server1 or WLS_MSM1, might remain. Ignore these configurations and do not restart the MSM servers.


To start system components, such as Oracle HTTP Server, use the startComponent script:

  • (UNIX) OHS_INSTANCE_HOME/bin/ ohs1

  • (Windows) OHS_INSTANCE_HOME\bin\ ohs1

You can start system components in any order.
