User Management for Non-Central AAE (PI-AF)

Use

In a dual-stack installation of SAP PI, you have the option to use the Advanced Adapter Engine (AAE) stand-alone, next to the Integration Server. This option is referred to as non-central AAE . That way, you have the runtime engines, AAE, and Integration Engine, de-coupled from each other at runtime.

By default, user management for the AAE in a such a scenario relies on AS ABAP as described under User Management and Authorization Concepts (Dual-Stack) .

Therefore, with regard to user management, there is still a coupling between both stacks. If for any reason the Integration Server system connected to the non-central AAE is down, the message processing on the non-central AAE might also be affected because the service users involved are still maintained in the Integration Server system.

Some scenarios require that the non-central Advanced Adapter Engine continues running when the connected Integration Server is down. Therefore, the user management for a non-central AAE can also be de-coupled from AS ABAP-based user management of the Integration Server. This option is referred to as local user management for non-central AAE .

Local User Management for Non-Central AAE

To configure user management in a way that it can be used de-coupled from the Integration Server, you have to perform specific steps during installation and post-installation of the non-central AAE.

Installing the Non-Central AAE

When installing the non-central AAE, after starting SAPInst , choose Parameter Mode .

Select the value Custom , make sure that you choose UME Configuration Use Java Database on User Management Engine screen.
