Updating SAP ABAP Systems on UNIX and Linux: SAP HANA DB

Setting the Operation Mode for the Update

Prerequisites

No operation modes should exist that contain servers other than those belonging to the current system.

Context

SPS update:

Various background jobs are started during the update. When you schedule jobs, a check is made to see whether the SAP instance on which you want them to run is defined in an operation mode. The operation mode specifies which services are offered by the work processes (dialog, update, background processing, enqueue, spool, and so on).

Release upgrade only:

Various background jobs are started during the upgrade. An operation mode defines how the resources of the individual instances of your system are configured. By specifying the operation mode, you can therefore determine which services are offered by the work processes (dialog, update, background processing, enqueue, spool, and so on) as well as the times that the services are available.

With the following steps, you perform the following tasks:

  • Deleting invalid operation modes

  • Defining the valid operation mode for the SAP instance on which you want to upgrade your SAP system

When you schedule background jobs, the Software Update Manager checks whether the SAP instance where the background jobs are intended to run is defined in an operation mode.

Procedure

  1. Call transaction RZ04 to check the definition of your operation modes. In addition, check the DUMMY operation mode. The DUMMY operation mode may have <host name>_<SID> entered as the server name. Change this entry to <host name>_<SID>_<instance number>.
  2. Delete the invalid operation modes. If operation modes contain names of servers other than those belonging to the system, problems may arise in the background interface in some phases. The jobs may be released, but not set as active (in theory, this affects all jobs scheduled to start on a specific server and triggered by an event).
  3. If the SAP instance on which you want to perform the update is not entered in an operation mode, create the operation mode for the update as follows:
    1. Call transaction RZ04.
    2. Choose Start of the navigation pathOperation mode Next navigation step CreateEnd of the navigation path.

      Enter a name for the operation mode, for example, Update. Enter a short description and then save the operation mode.

    3. Make sure that the instance required for the update has been started up.
    4. Position the cursor on the new operation mode and choose Start of the navigation pathOperation mode Next navigation step Maintain instances Next navigation step Instances/OP modesEnd of the navigation path.
    5. Choose Start of the navigation pathSettings Next navigation step Based on act. status Next navigation step New Instances Next navigation step GenerateEnd of the navigation path.

      This displays all instances and their current configuration.

    6. Choose Save.
    7. Call transaction SM63 to enter the operation mode you have defined as an active operation mode for 24 hours (select Normal operation (24 hours)).
