| Create an Installation | The instance administrator unzips the distribution. | The instance administrator untars the distribution file and run the installer. |
| Create an Instance | The instance administrator runs the ttInstanceCreate utility. For client-only instances on Linux and UNIX, the ttInstanceCreate -clientonly option is required.

The instance is created as part of the installation process. |
| Modify an Instance | The instance administrator runs the ttInstanceModify utility. |
The instance administrator runs the ttmodinstall utility. |
