Shut Down Ingres and Back Up System
You should perform a clean shutdown of Ingres, clearing all transactions from the transaction log, and then back up your system.
To perform a clean shutdown of Ingres
1. Shut down Ingres.
2. Restart Ingres.
3. Shut down Ingres again.
4. Check the recovery process log (iircp.log) for the message “RCP Shutdown completed normally.”
To back up your system
5. Use a command appropriate to the platform to perform the backup.
6. Back up all Ingres directories, including data, checkpoint, journal, dump areas, and the $II_SYSTEM/ingres directory containing Ingres files and executables.
7. Back up the application directories
Note: Watch for symbolic links and cross-mounts; make sure real data is saved and not a symbolic link.
8. Include the root file system in the backup if Ingres is typically started up at boot time. Alternatively, print a copy of any Ingres boot time startup and shutdown scripts.
9. Perform the backup twice to ensure that you have an extra copy of your backup. This step ensures maximum safety.
10. Check the backup media to ensure that the backup can be read. If your backup medium is tape, use new tapes, and clean the tape drive before the backup.
11. Restart Ingres.
