New Instance Name

By default, the installer automatically searches the $SYBASE directory for existing DA installations and uses the configuration values from the valid instance directory that has been most recently modified. You may install another instance into same directory for your upgrade or reinstallation.

To install another instance into the same $SYBASE directory, you must force the installer to use the new instance name, to stop it automatically choosing an existing one. If you choose a new instance name for an existing installation, the installation process is similar to an upgrade which reuses the existing configuration values.

Note: Sybase recommends that you do not install two or more instances of the same type into the same folder structure. The installer's registry records the most recently installed instance. If you uninstall DA, the most recent instance created is removed.

Specify the agent or server instance name, issue these commands:

DA server:
- GUI mode
```
setup.exe/bin -i swing -DDA_SERVER_INSTANCE_NAME=myserver2
```
- Console mode
```
setup.exe/bin -i console -DDA_SERVER_INSTANCE_NAME=myserver2
```
- Silent mode – make sure the DA_SERVER_INSTANCE_NAME in the silent install installation properties file uses a different instance name than any existing instances.

DA agent – use the DA_AGENT_INSTANCE_NAME parameter.
