Notes
Announcements
HP Serviceguard Extension for SAP (SGeSAP) on HP-UX, extends HP Serviceguard's failover cluster
capabilities to SAP application environments. It is intended to be used in conjunction with the HP
Serviceguard product.
SGeSAP provides a single, uniform interface to cluster ABAP-only, JAVA-only, double-stack and
split-stack installations of SAP Netweaver based SAP applications. These are supported in a range
of versions as specified in this release notes.
The clustered software instances include SAP ABAP Central Services, SAP JAVA Central Services,
SAP ABAP Application Servers, SAP JAVA Application Servers, SAP Central Instances, SAP Enqueue
Replication Servers, SAP Sybase databases, IBM DB2 databases, Oracle single-instance databases,
SAP MaxDB databases, SAP Web Dispatcher instances, SAP Gateway instances, SAP liveCache,
and SAP MDM components.
For some platforms, support for liveCache hot standby clusters is included. Software monitors that
can check the responsiveness of the major interaction interfaces of the clustered software components
is included. The SAP Netweaver and SAP liveCache monitors can distinguish between the manual
halt [of a component] versus the failure of a component configured in a package. In the case of
a manual halt the package continues to run
It is possible to combine all clustered components of a single SAP system into one failover package
for simplicity and convenience. There is also full flexibility to split components up into several
packages to avoid unwanted dependencies and to lower potential failover times. Multiple SAP
applications of different types and the release version can be consolidated in different packages
of a single cluster. SGeSAP enables SAP instance virtualization. It is possible to use SGeSAP to
manually move SAP Application Server Instances between hosts to quickly adapt to changing
resource demands or maintenance needs.
