HP Serviceguard Extension for SAP (SGeSAP) manual

Currently Oracle does not support the failover of databases based on HP 9000 binaries to nodes using executables compiled for the Integrity platform. Consequently this means, the use of an Oracle database package in a mixed environment is restricted to one platform. Therefore the database package must be kept either on purely HP 9000 or Integrity nodes. The installation and configuration of a database package should have been done already, as mentioned in the prerequisites. Oracle database servers at least need to match the version number that the used Oracle client libraries have. Mixed clusters are only possible using Oracle 9i versions, because the Integrity executable set of the SAP kernel uses Oracle 9i client libraries. The SAP kernel acts as an Oracle client. As a consequence, Oracle 8 database releases need to be upgraded before they can be used in mixed cluster setups. HP recommends to use the highest database server patch level that is supported for the used SAP component. This will be at least Oracle 9.2.0.3. It is not possible to use a HP 9000 based Oracle 8 database for environments that might serve SAP components on IPF.
