HP Serviceguard Extension for SAP (SGeSAP) manual Cd /sapmnt/SID Mv exe exepa

•SGeSAP packages that do not contain database components can be configured to run on any node in the cluster. This includes ci, jci, [a]rep and d package types.

•SGeSAP database instance packages must be configured to run only on either Integrity or HP 9000 nodes. This includes db, jdb and lc package types and all package types composed of these.

NOTE: Always check for the latest versions of the Serviceguard Extension for SAP manual and release notes at http://docs.hp.com/en/ha.html. Especially for mixed cluster setups and configurations refer to SAP note 612796 - 'Move to HP-UX Itanium systems'.

Even though the SAP HP 9000 executables might run on Integrity systems under the ARIES binary emulator, SAP has no plans to support HP 9000 executables on Integrity systems. Consequently, it is mandatory to obtain SAP executables for the additional Integrity nodes. So the SAPEXE and SAPDBEXE.SAR archives for the Integrity based systems have to be downloaded, for example from Service Marketplace (http://service.sap.com) for the corresponding already installed SAP component.

The SAP kernel executables for HP 9000 and Integrity processors need to be in sync with their patch levels. It is guaranteed that the same patch levels are available from SAP at all times.

System Configuration Change: PI010

The shared disk containing SAP executables, profiles and globals (/sapmnt/sapmnt/<SID>) must have sufficient disk space for a full set of additional Integrity binaries.

System Configuration Change: PI020

The SAP executable directory is the key point where the redirection for HP 9000 or Integrity executables is performed, so the HP 9000 executables need to be moved to a distinct directory.

cd /sapmnt/<SID>

mv exe exe_pa

System Configuration Change: PI025

Create a directory for the Integrity binaries.

cd /sapmnt/<SID>

mkdir exe_ipf

and extract the downloaded SAR archives

SAR xvf <...>/SAPEXE.SAR /sapmnt/<SID>/exe_ipf

SAR xvf <...>/SAPDBEXE.SAR /sapmnt/<SID>/exe_ipf

System Configuration Change: PI030

The executable directory is substituted by a link referencing another local symbolic link that distinguishes between a HP 9000 or Integrity based system.

cd /sapmnt/<SID>

ln -s /sapmnt/<SID>exe_local exe

Take note that the referenced local executable link does not reside on the shared disc - it is on the local file system on each cluster node pointing to the appropriate executables for a HP 9000 or Integrity platform. In that case for a HP 9000 system:

cd /sapmnt

ln -s /sapmnt/<SID>/exe_pa /sapmnt/<SID>exe_local

System Configuration Change: PI040

Similar to the local executable link on HP 9000 systems, perform the step for the Integrity node:

cd /sapmnt

ln -s /sapmnt/<SID>exe_ipf <SID>exe_local

System Configuration Change: PI050

Make sure to have a local copy of the Oracle client libraries on all nodes.

You'll need to download the HP 9000 version for the PA RISC nodes and the IPF version for the Integrity nodes from http://service.sap.com.
