Oracle Audio Technologies B31679-01 Installation instances, Instance names, Instance port numbers

Installation instances

On UNIX, you can install more than one instance of any TimesTen release. By default, the instance name for this release is tt70.

If an instance of a particular release of TimesTen already exists on the machine, and you would like to install a second instance of the same TimesTen release, you must supply a unique instance name and port number. The TimesTen installation script can detect if an instance of the particular release of TimesTen already exists on the machine and will prompt you for a new instance name and port number for the main TimesTen daemon.

The instance name appears in the installation path and is the key used to access all necessary information about that particular installation of TimesTen. The instance name also appears in some TimesTen file names.

Note: On Windows, you can only install one instance of any major and minor release of TimesTen. The TimesTen installation script does not prompt you to supply an instance name.

Instance names

The instance name is case-insensitive and can have up to 255 characters. The name must be NON-NULL and can include underscores ( _ ) or period (.), but no other special characters.

You can retrieve information about the TimesTen instance name, release number and port settings using the ttVersion utility.

Instance port numbers

Any time that you install more than one instance of TimesTen with the same major and minor release numbers on the same machine, the TimesTen installation script also requires that you specify a non-default TCP/IP port number for the main TimesTen daemon.

All TimesTen data stores that replicate to each other must use the same daemon port number, except when the -remoteDaemonPort option is specified in duplicate operations. This port number is set at install time and can be verified using the ttVersion utility.
