Disable Ingres Startup
If Ingres starts automatically when the machine boots up, turn auto-starting off until the upgrade is complete.
To disable Ingres startup and put operating system changes into effect
1. Follow the procedures for your platform:
UNIX: On most UNIX platforms, a file in a system startup directory performs Ingres startup and shutdown; place an “exit 0” at the top of this file. The system administrator may need to perform this step if it requires root privilege. (The system startup directory depends on your platform--/etc/init.d, or /sbin/init.d, or a similar name).
Windows: If Ingres is run as a system service, set the service to start manually instead of automatically.
3. Reboot, if necessary, to put the operating system parameter changes into effect.
Note: This step is recommended even if you are doing a clean installation upgrade. By leaving the old installation shut down, you eliminate the chance that someone will connect to it by mistake later.
