You can add an instance to the cluster either interactively, with sybcluster prompting you for required values, or by using an input file.
add instance creates a local system
temporary database for the new instance. Make sure that there is
sufficient space on the device.
If you add the instance interactively, Adaptive Server prompts for:
The instance name, if one was not specified in the command statement
The name of the node hosting the instance
The port number of the Unified Agent on the node
The query port number
The primary and secondary address of the node
The primary and secondary port specifications
If you add the instance using an input file, make sure the file mirrors the format of the cluster input file (see the installation guide for your platform), although you need to include definitions only for the new instance. If auxiliary servers are defined, include port and other information required for configuring the auxiliary servers for the new instance.
For example, to add an instance using an input file, enter:
add instance new_instance file /$SYBASE/myfile
To add an instance interactively, enter:
add instance new_instance
