Purpose

If you are new to ON-Archive , which is a complex tool to use, this section helps you to get started. ON-Archive is a tool for data recovery (that is, database archive, logical-log backup, and restore) for an Informix database with the SAP System.

If you use the SAP scripts and the DBA Planning Calendar (part of the Computing Center Management System in the SAP System), you do not need to enter ON-Archive commands manually. SAP recommends that you use the scripts and the DBA Planning Calendar, because they make it easier to set up and use ON-Archive .

Prerequisites

Read the Informix documentation about ON-Archive before you start. You must have a UNIX platform, because ON-Archive is not available for NT platforms. To see how this process fits in with the overall process of using ON-Archive for data recovery, see ON-Archive for Data Recovery.

Note

The programs that make up the data recovery tool ON-Archive use a command-line interface and include onarchive , ondatartr , onautovop , oncatlgr . For more information about these programs – all delivered with your Informix database – see the Informix documentation.

Process

  1. You decide how you want to perform database archives and logical-log backups. Refer to Approach to Archive (ON-Archive) and Approach to Logical-Log Backup (ON-Archive).
  2. You make sure you meet the requirements for your chosen approach. Refer to Requirements for an Archive (ON-Archive) and Requirements for a Logical-Log Backup (ON-Archive).
  3. You decide if you want to use the SAP scripts for ON-Archive . For more information:

    4. – If you decide to use the scripts, see SAP Scripts for ON-Archive.

    – If you decide not to use the scripts, see Entering ON-Archive Commands Manually.

  4. You set up the volume sets and volumes to meet the requirements of your chosen approach. Refer to Volume Sets and Volumes for ON-Archive. Note that, if you decide to use the SAP scripts, you can set up the required volume sets and volumes with the scripts arcprep and arcvolum .
  5. You edit the configuration files used by ON-Archive according to the requirements of your chosen approach. Refer to Configuration Files for ON-Archive. Make sure you define the devices to be used for database archive and logical-log backup.

For an overview of some of the configuration tasks described above, see Configuration of ON-Archive.
