5 Interprocess Communications
This chapter describes ” Installing OpenSSH ” on page 25.
The Adaptive Computing Integration Software uses different communication methods to enable all
the different components to communicate with each other. For successful implementation, it is
necessary to understand the communication methods and the dependencies between products.
The following diagram displays a summary of the inter-process communications in the adaptive
landscape.
Figure 12 Communication between systems
Installing OpenSSH
Secure Shell (OpenSSH) is used for the communication between the SAP ACC server to the
managed nodes, as well as between the HP SIM and the managed nodes. SAP and HP SIM have
different methods to install and configure SSH to the host, depending on what is already configured.
This can result in some issues when configuring the integrated solution.
The following is a high level sequence for installing OpenSSH in the adaptive landscape. For more
details on installation and commands, please refer to the user documentation on OpenSSH or the
Installation Guides for SAP and HP SIM.
