Updating SAP ABAP Systems on UNIX and Linux: IBM Db2 for Linux, Unix, and Windows

Determining the Host for the Preparations

Context

Execute the update on the host where a suitable, configured and set up application server instance is running. Usually it is the host of the primary application server instance, but it is also possible to use the host of an additional application server instance.

Procedure

Decide which hosts you need for the update preparation and the actual update of the SAP system:

  • Host with a configured and set up application server instance. Usually it is the host of the primary application server instance, but it is also possible to use the host of an additional application server instance.

    You have to execute the update on the host where the primary application server instance is running. However, under certain circumstances it is possible to use an additional application server instance.

  • Database host - you have to perform the actions that affect the database on the database host.
  • User Management Engine host - the remote instance host where the User Management Engine (UME) is located must be running.
