HP Serviceguard Extension for SAP on Integrity Linux (SGeSAP/LX
IPF) extends Serviceguard's powerful failover capabilities to SAP
environments. It continuously monitors the health of each SAP node and
automatically responds to failures or threshold violations. It can also
minimize planned downtime when performing SAP upgrades.
Serviceguard protects the SAP central instance and database by defining
them in Serviceguard packages. Application Servers can optionally also
be put into Serviceguard packages.
This chapter provides an overview of how SGeSAP/LX IPF works. Topics
are as follows:
• Overview of SGeSAP on Intergrity Linux
• Application Servers
