Before creating a new server instance, perform the following checks:
Check whether you have created a configuration. Creating a new server instance needs an existing instance configuration to be specified.
Check if all the available nodes in the Server Farm already have an instance of the required configuration. You can not create duplicate instances.
Create a new server instance by performing the following tasks:
Click Configuration tab and select New from the action list.
In the New Instance Wizard page, select the configuration for which you need to create an instance and click Next button.
Select the nodes on which instances of the selected configuration [Step 2] should exist. Click Next button.
View the summary of your selection. Click Next button to view the result of the operation.
For creating a server instance, execute the following command:
wadm> create-instance --user=admin --password-file=admin.pwd --host=serverhost --port=8989 --config=config1 serverhost
