Maximum Availability Architecture (MAA)Maximum Availability = Unbreakable Architecture + Best Practices

Oracle's best practices blueprint based on proven Oracle high availability technologies and recommendations

Technology + Configuration + Operational Practices

Applications, Enterprise Manager, Application Server, Collaboration Suite and Database

• Constantly validated and enhanced as new products and features become available

• Focused on reducing unplanned and planned downtime

• Focused on making our customers successful• Papers published to the Oracle Technology Network (OTN)

Siebel MAASiebel HA Deployment Options

• Load Balancing• Client initiated workload is distributed across multiple

component instances running on multiple servers.

• Distributed Services• Siebel Server initiated workload is distributed across multiple

component instances running on multiple servers.

• Clustering• Server clusters consist of two or more physical servers linked

together so that if one server fails, resources such as disks, network addresses, Siebel Servers and Gateway Servers can be switched over to another server.

Outage Type Oracle Solution Benefits Recovery Time

Load Balancing

Remaining nodes pick up the slack

Affected users reconnect

Distributed Services

Remaining nodes continue processing No downtime

Siebel Node or Component Failures

Clustering Automatic failover to surviving nodes

Seconds to minutes

Automatic recovery of failed nodes and instances, transparent application and service failover

Data Guard Fast Start Failover Seconds to 5 minutes *

Users failover transparentlyUpdates may need to be re-submitted

Site Failure

Database Node or Instance Failures

RAC

* It will be necessary to re-extract Siebel Remote users after site failover

Siebel MAA DemonstrationHardware Vendor Partners

• Part of MAA means proving and testing our best practices, and working closely with our hardware vendor partners to ensure that our joint solutions work well together.

20

Siebel MAA DemonstrationTest Configuration

• The demonstrations were developed and executed using HP Systems hardware and software and F5 load balancers

• Hardware• F5 BIG-IP Local Traffic Manager v9 - 3400 Series• HP DL145 G2 running HP Load Runner v8.1 for load generation• HP Integrity rx2620 servers for the application tier • HP Integrity rx4640 servers for the database tier • HP StorageWorks EVA4000 for database storage

• Software• HP-UX 11i v2 B.11.23 for Web and Siebel Servers• HP-UX 11i v3 B.11.31 for Database Servers• HP Serviceguard Version A.11.18 for Siebel Server clustering

• Oracle Enterprise Manager Grid Control was used to monitor the systems

Siebel MAA DemonstrationOracle RAC Instance Failure

1. System running under load – approximately half the database connections on each RAC node

2. Abort RAC instance!3. Surviving instance performs recovery4. Siebel Servers reconnect and are routed to the

surviving node5. Oracle transparent Application Failover reconstructs

the database sessions6. Users continue processing

Siebel MAA DemonstrationSite Failure

1. System running under load on primary site2. Power down primary site nodes3. Siebel users begin to receive errors in client4. Oracle Data Guard Broker detects database down and

performs database failover to standby5. DB_ROLE_CHANGE trigger fires to execute Siebel failover

script6. Siebel failover script starts Siebel Gateway, Siebel Servers and

Web Servers7. Client connections switched to standby site through DNS push8. Siebel Users reconnect and are routed to standby site
