Getting Started with ON-Archive 

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 R/3 System. If you use the SAP scripts and the DBA Planning Calendar (part of the Computing Center Management System in the R/3 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.

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. 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. 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. 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. 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. 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.
