Modular-style SAP application cluster packages
Generic hardware clustering technology needs to be extended and integrated with application
software clustering to create complete coverage of outages and to allow easy, effective
administration for the whole solution.
HP SGeSAP/LX A.06.00 introduces Serviceguard cluster modules for major SAP application
components on Linux platforms. In modular-style packaging, the application-specific cluster
configuration is integrated with the generic Serviceguard cluster configuration. Only one central
configuration is maintained for each package.
Seviceguard becomes enhanced by five major new modules.
The SAP instance module clusters one or multiple SAP Netweaver ABAP and or JAVA stack instances
that belong to a single SAP system ID. The module provides individual handling for a variety of
SAP instance types, including:
• Central Instances
• System Central Service Instances (for ABAP and or JAVA)
• Enqueue Replication Service Instances
• ABAP and JAVA Application Instances
• Gateway Instances
• Webdispatcher Instances, and
• MDM instances
The dbinstance module clusters the single-instance database of a Netweaver stack combining the
uniform SAP database handling and a fallback to database-technology native operations. Supported
database technologies include SAP Sybase, SAP MaxDB, and Oracle RDBMS.
The sapextinstance module allows triggering best-effort start and stop operations for non-clustered
SAP instances as part of regular package operations. These additional instances can belong to
the same System ID as the instances in the package or any other SAP system IDs. They can run on
cluster nodes or cluster-external servers. This functionality can for example be used to move SAP
