This section describes how to prepare to use the SAP script arcpanic with ON-Archive to automatically perform an emergency logical-log backup on your Informix database. You must make these preparations before the emergency logical-log backup occurs.

For more information if you do not want to use the SAP scripts, see Emergency Logical-Log Backup Without SAP Scripts (ON-Archive).

1. Set up ON-Archive correctly.

Setting up ON-Archive takes time. If you need to do an emergency backup immediately, and you have not already set up ON-Archive , use the procedure Emergency Backup without SAP Scripts (ON-Archive) instead.

For further details on preparation for ON-Archive , see Getting Started with ON-Archive and the Informix documentation.

2. Copy scripts arcprep and arcpanic .

The script arcprep is used to set up volume sets and volumes (see next point) and arcpanic is used to run the emergency backup procedure. Refer to Preparing SAP Scripts.

3. Set up volume set ONDATARTRLOG .

Now you can start the procedure. Refer to Performing Emergency Logical-Log Backup Using SAP Scripts (ON-Archive).
