• Oracle’s recent dual core pricing announcements will level the playing− Multicore RISC processors 0.75
e.g. IBM Power5, Sun UltraSPARC IV, and HP PA-8800− Multicore Intel &AMD processors 0.5
e.g. Montecito ☺− Multicore Sun T1 processors 0.25− Single core CPU 1
• Example: # of Oracle licenses required for 32 core server− IBM = 32 x 0.75 x $40k = $960k− HP Montecito = 32 x 0.5 x $40K = $640k
• Standard Edition based on sockets (not cores) 8 Dual Core

• Applications and the database are managed the same way
• Provides initial support for 4-node clusters with SG CFS for RAC, 8 nodes will follow
• Ability to see the various db files (and associated sizes) with normal UNIX commands
• CFS can be used for Oracle data files and for Oracle binaries, configfiles, and logs
• Ability to use all normal backup utilities with db files on a CFS
• Currently only local cluster supported. Please contact us if you have customers who want Extended Cluster with CFS!

Management of RAC databases –Advantages using CFS• Best management option
for all kind of files− addition/deletion of files− possibility to grow Oracle
data files− possibility for file system backup
• Support for installation of binaries into CFS− Oracle is full cluster file system aware− configuration file names are node/instance specific:
• CRS log files: [nodename].log• CSS log files: ocssd[Nodenumber].log
5/17/2006 Copyright © 2003 HP corporate presentation. All rights reserved. 20
Backup & Recovery with RAC –Advantages using CFS
• Having archive logs on a CFS simplifies the backup significantly.− No need of cross-
instance archiving− No NFS cross
mounts− No manual
intervention in case a node/instance goes down

What is ODM?• API defined by Oracle to enhance File
Management and Disk I/O throughput – this API is available to vendors.
• ODM API co-developed by Oracle and VERITAS• Designed for Oracle9i or later• Replaces Quick I/O which is up to Oracle8i• The ODM interface provides unified I/O and file
management for Oracle servers and reduces the number of system calls that Oracle servers generate. All Oracle processes use a single I/O library.
• Available in all Serviceguard Storage Management Suite for Oracle Bundles

Why HP SG / SGeRAC together with Oracle Clusterware• HP Serviceguard as proven
cluster layer with 150,000+ licenses
• HP Serviceguard is integrated with the HP Virtual Server Environment
• Continue to use HP Serviceguard to make your complete cluster high available including 3rd party applications
• HPs Enterprise Cluster Master Toolkits (ECMT) to rapidly implement and deploy applications under the control of HP Serviceguard
• Increase network reliability: Oracle Clusterware does not provide any protection for the critical private interconnect.
• Integration with HP Extended Cluster (aka Campus Cluster) and HP ContinentalClusters.
• Make use of a Cluster File System
• Make use of HP's shared logical volumes
• Co-existence of Oracle9i RAC and RAC10g on the same cluster

HP Serviceguard Extension for RAC (SGeRAC)• Support for 9i RAC & RAC10g• Cluster management is provided with SG• Shared Logical Volume Manager features are enabled
with SGeRAC• Support for 16 nodes with SLVM• SGeRAC runs on top of SG starting with 11.15• Support for SG Extension for Fast Failover• Support for Rolling Upgrade starting with 11.15• SGeRAC does not support mixed clusters. All nodes must
either be Itanium2 or PA-RISC, but not both in the same cluster.
• Online Node Reconfiguration Support (SNOR)− Being able to reconfigure SLVM while VG is activated in only one
administrative node in the cluster• Online Node Addition Support
− This feature requires changes in SG and Kernel LVM

Integration SGeRAC & Oracle Clusterware• In a combined SGeRAC & Oracle Clusterware
environment−SGeRAC is responsible for
• Cluster membership info provided to Oracle Clusterware CSS (Cluster Synchronization Service) daemon
• Management of SGeRAC provided storage options (SLVM, CVM, CFS)
• Startup of Oracle Clusterware within an HP Serviceguard package (required 10.1.0.4).
−Oracle Clusterware CRS (Cluster Ready Services) is responsible for• Management of database and associated resources (instances,
services, VIPs, listeners, ..)• Management of Oracle ASM

SGeRAC and Oracle Clusterware -best practices• Disable automatic start-up of Oracle Clusterware
− /sbin/init.d/init.crs disable• Ensure that Oracle does not activate/deactivate any
volumes− no /var/opt/oracle/oravg.conf
• Configure SG package to activate/deactivate shared VGsand to start/stop
• Let Oracle Clusterware start/stop all registered resources such as db instances, listener, VIPs, ...
• Configure same heartbeat interfaces for SGeRAC & Oracle
• Oracle VIP must be configured for a public network that is not used by any other SG application
• SG/SGeRAC will provide high availability for all networks

Oracle RAC10g on HP-UX with SG/SGeRAC & RAW• Oracle Clusterware running
integrated on top of SG/SGeRAC 11.16+
• Cluster Membership is derived from SG/SGeRAC: mature and proven cluster layer
• SG Package Manager to provide high availability of other applications
• Provides high availability for all networks
• Integration with HP Extended Cluster (aka Campus Cluster) and Continental Clusters.
• Support for shared logical volume manager (OCR, VOTING, data files, …)
• Optimal performance• Lacks file system capabilities• Slightly more complex to handle

Oracle RAC10g on HP-UX with SG/SGeRAC & SLVM/ASM
• Prior to SGeRAC 11.17, ASM is NOT supported in SG/SGeRAC configurations
• Only support for RAC 10g R2:− no support for RAC10g R1− no support for single instance− no support for Extended Cluster
(irrespective of whether the inter-site mirroring is via ASM or HP-provided volume manager)
• Each ASM disk group member must be a SLVM raw logical volume
• Max # of nodes in cluster: without MNP/Simple Dependency Framework - 16, with Framework – 4
• SLVM provides active/standby multi-pathing support for RAC and single instance (“pvlinks”)
• Leverage cluster-wide device name feature of SLVM

ASM
• The Oracle Clusterware to provide RAC cluster membership
• Oracle ASM for storage management• High availability for other applications
running on same cluster can be implemented with HP SG (no SGeRAC) or with RAC10gR2 Cluster API
• CRS monitors the virtual IP address (VIP) and not other network interfaces. Therefore, additional software necessary to provide HA features for private interconnect (e.g. HP APA)
• No shared logical volume manager supported for Oracle files (OCR, VOTING, data files, …)
• Supported with Oracle RAC 10gR1+

– no file system capabilities– more complex to handle
+ optimal performance+ no additional software licenses for volume manager / file systems+ supported for 9i + 10g
RAC10g with HP SG/SGeRAC.... and RAW
– no HA for networks-– ASM lacks multi-pathingcapabilities– you must use ASM, no SLVM– only supported with 10g
+ easy support model (all from Oracle)
RAC10g with Oracle Clusterware Only and ASM
– no support before 10gR2– no support for single instance– no support for Extended Cluster– performance impact of extra layer of volume management
+ no additional licenses for volume manager / file systems+ easy management with ASM+ SLVM provides active/standby multi-pathing support for RAC and single instance (“pvlinks”)

Interconnect
5/17/2006 Copyright © 2003 HP corporate presentation. All rights reserved. 40
Interconnect for RAC on HP-UX• Crossover Cables are not supported by Oracle as an interconnect
with 9iRAC/10gRAC on any platform.• Important criteria for interconnect:
− Throughput of interconnect: 1GB Ethernet / 10GB Ethernet / InfiniBand(today 10GB/s) / Hyperfabric2 (4 GB/s)
− Latency of protocol• UDP: available for all network adapters; ~ 50 microseconds• Low latency implementations:
− RDS planned− RDMA out of scope− HMP over Hyperfabric: not any longer strategic ...
− Distance• InfiniBand: max 10m copper cable• Hyperfabric2: max 200m cable
− High Availability• For most customer implementations UDP over Ethernet is sufficient.• Goal : Replace HMP/HyperFabric with Infiniband or 10Gigabit
Ethernet.
