Upgrade with SAP MaxDBLocate this document in the navigation structure

Use

You normally upgrade the SAP MaxDB database before an SAP system upgrade, which causes extra downtime for the SAP system. The SAP MaxDB upgrade always involves the following activities:

  • Upgrading the SAP MaxDB software

  • Upgrading the SAP MaxDB system tables

  • Keeping a copy of the currently installed database software in case of error

Process

  1. You read the upgrade documentation.

    You familiarize yourself with the upgrade documentation so that you know what to expect during the upgrade.

  2. You plan the upgrade.

    It is risky to start the upgrade without knowing the procedure, simply hoping that everything runs well. A lack of planning can lead to unexpected problems, which can considerably increase the downtime of the SAP system.

  3. You rehearse the upgrade using a test system.

    The best preparation of all is to rehearse the upgrade fully using a test system that is as similar to the production system as possible.

Result

You can now upgrade the database with the minimum possible downtime.
