Announcements

HP SGeSAP/LX (Serviceguard Extension for SAP on Linux ) extends HP Serviceguard's failover

cluster capabilities to SAP application environments. It is intended to be used in conjunction with

the HP Serviceguard Linux product and the HP Serviceguard Toolkit for NFS on Linux.

HP SGeSAP/LX provides a single, uniform interface to cluster ABAP-only, JAVA-only, double-stack,

and split-stack installations of SAP Netweaver based SAP applications and their databases. Software

instances clustered by HP SGeSAP/LX 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 HANA scale-up system replication database instance pairs,

SAP single-instance Sybase ASE databases, Oracle single-instance databases, IBM DB/2

single-instance databases, SAP single-instance MaxDB databases, SAP Web Dispatcher instances,

SAP Gateway instances, SAP liveCache, and SAP MDM components.

HP SGeSAP/LX handles SAP Unicode and non-Unicode installations.

HP SGeSAP/LX implements Automated Enqueue Replication with Follow-and-push failover policy

between up to two SAP Central Service Instance (CSI) and SAP Enqueue Replication Instance pairs

in the clusters with up to sixteen nodes.

All HP SGeSAP/LX components support Serviceguard Live Application Detach (LAD), Serviceguard

Package Maintenance Mode, and the SAP Online Kernel Switch technologies to minimize planned

downtime.

Optional software monitors that check the responsiveness of the major interaction interfaces of the

clustered software components are included.

HP SGeSAP/LX discovers SAP installations and their configuration settings on the cluster nodes

and provides a guided package creation dialog with pre-filled cluster configuration settings.

HP SGeSAP/LX optionally integrates with the SAP startup framework. HP SGeSAP/LX bundles a

SAP HA API implementation according to SAP’s specifications.

Native, node-local restart capabilities by SAP are supported for SAP message services. They are

available as built-in feature of HP SGeSAP/LX for the SAP Enqueue replication instances and the

SAP Startup Services of the SAP Central Service Instances.

All SAP Netweaver and SAP liveCache monitors can distinguish between the manual halt (of a

SAP software component) versus the failure of a component configured in a package. In the case

of a manual halt the package continues to run, but suspends the monitoring automatically. HP

SGeSAP/LX blocks any halt attempt for SAP Netweaver software components, if the halt operation

is not issued by the cluster software.

It is possible to combine all the clustered components of a single SAP software stack into one

failover package for simplicity and convenience. There is also full flexibility to split components

up into several packages to avoid 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. HP SGeSAP/LX enables SAP instance virtualization.

It is possible to use HP SGeSAP/LX to manually move SAP Application Server Instances between

hosts and quickly adapt to changing resource demands or maintenance needs.
