Process documentation Approach to Archive (ontape)  Locate the document in its SAP Library structure

Purpose

To make sure that you can archive the Informix database with ontape in the best way, you have to decide on your approach. If your approach is poor, you might later have trouble using the archived data to restore the database.

Prerequisites

You have completed the preparations necessary to set up ontape . Refer to Configuring ontape.

There are the following limitations for archiving with ontape:

You cannot archive in parallel (one group of dbspaces to one device and another group to a second device, and so on) to reduce archiving time. This disadvantage tends to be more limiting with larger databases. However, you can use ontape to restore selected dbspaces if required.

ontape always writes its archives to tape (or tape compatible devices). Since additional tapes might have to be mounted during the archive procedure, an operator should always be present.

To overcome these limitations, you must start using ON-Archive or ON-Bar . Refer to ON-Archive for Data Recovery or ON-Bar for Data Recovery.

Process Flow

  1. You develop good practice for archives.
  2. You choose the archive level and frequency.

Result

You can now check the Requirements for Archive (ontape).
