Manages concurrent UltraLite database connections from applications, and allows the UltraLite engine to run as a daemon using the -ud option.
uleng17 [ -ud ]| Option | Description |
|---|---|
| -ud | Lets you run the engine so that it continues running after the current user session ends. When you start the daemon directly using the -ud option, the uleng17 command creates the daemon process and returns immediately (exiting and allowing the next command to be executed) before the daemon initializes itself or attempts to open any of the databases specified in the command. |
The UltraLite engine does not display a messages window on startup.
The UltraLite engine should be used by an application in scenarios where multiple processes could be accessing the same database at the same time. The engine is installed in the SQL Anywhere bin32 or bin64 directory because the UltraLite desktop administration tools use the engine to connect to databases.
Using the -ud option, you can run the UltraLite engine so that when you log off the computer, the database engine remains running. (Normally when you log off the computer, all applications associated with the session shut down.)
