Planning the HA for SAP liveCache Installation and Configuration

This section contains the information you need to plan your HA for SAP liveCache installation and configuration.


Note - If you have not already done so, read your SAP documentation before you begin planning your HA for SAP liveCache installation and configuration because your SAP documentation includes configuration restrictions and requirements that are not outlined in Oracle Solaris Cluster documentation or dictated by Oracle Solaris Cluster software.


Configuration Requirements


Caution

Caution - Your data service configuration might not be supported if you do not adhere to these requirements.


Use the requirements in this section to plan the installation and configuration of HA for SAP liveCache. These requirements apply to HA for SAP liveCache only. You must meet these requirements before you proceed with your HA for SAP liveCache installation and configuration.

For requirements that apply to all data services, see Oracle Solaris Cluster Data Services Planning and Administration Guide.

Standard Data Service Configurations

Use the standard configurations in this section to plan the installation and configuration of HA for SAP liveCache. HA for SAP liveCache supports the standard configurations in this section. HA for SAP liveCache might support additional configurations. However, you must contact your Oracle service provider for information on additional configurations.

Figure 1-2 illustrates a four-node cluster with SAP APO Central Instance, APO application servers, a database, and liveCache. APO Central Instance, the database, and liveCache are configured as failover data services. SAP xserver can be configured only as a multiple master data service. APO application servers can be configured as scalable or failover data services.
