NOTE: Geodatabases created with an ArcGIS Server Enterprise license on Windows only

It is possible to install more than one instance of ArcSDE for different database management systems on the same machine. Some ESRI products share the same administrator commands (for example, sdeservice, sdemon). To successfully run more than one ArcSDE component installation for different DBMSs on the same machine, follow the steps below. For information on installing multiple instances of the ArcSDE component for the same type of DBMS on the same machine, see Using multiple geodatabases within a DBMS.

1. Before running the postinstallation setup, make sure the ArcSDE component installation you want to administer is the ESRI product listed first in your System PATH.
2. Make sure SDEHOME in your PATH is set to your current ArcSDE installation location.

NOTE: Steps 1 and 2 above apply whenever administrator commands for ESRI products are run. If you do not change your System PATH, the administrator commands for the wrong product may be run.

3. Run the ArcSDE Post Installation wizard for the chosen DBMS.

You can now manage the multiple ArcSDE services/installations by switching back and forth between ArcSDE environments through the System Control Panel or by using the ArcSDE administrative commands with the –H option set to the appropriate SDEHOME location.
