Secret Sauce for Middleware RAC Integration?

We don’t seem to be realizing our middleware performance, reliability and

availability when used with RAC. I purchased Oracle RAC to fix

this but it seems like my middleware needs help

Did you know if your application runs on WebLogic Serverthere is a reliability, availability and

performance enhancingRAC integration capability called

Active GridLink for RAC?

What don’t conventional Application

Servers have?• No engineered RAC integration for data sources

• No Fast Connection Failover for rapid failure detection

• No support for runtime continuous connection load-

balancing/re-balancing

• No Transaction Affinity to enable XA and RAC to work together

with optimal performance

Result: Lack of Resiliency with Conventional Application Servers’ Usage of Oracle RAC

What will happen with conventional

Application Servers when a RAC node is taken offline?• From seconds to potentially minutes service interruption

• Minimum several minute wait for server connection pool to

recover and be cleaned

• Connection pool not automatically rebalanced

• Possible for transaction to be left in in doubt state

• Possible for application requests get blocked relying on TCP/IP

timeout

What does WebLogic have with RAC?• Simple, declarative integration with RAC

• Fast Connection Failover for rapid failure

detection/ abort and invalid connection removal

• Support planned/unplanned downtime

• Automatic new/re-join instance integration

• Runtime Connection Load Balancing to manage pooled

connections for performance/scalability

• Transaction Affinity for XA and RAC performance

• Session Affinity for high performance for hot data (repeated

access of client records)

What will happen with WebLogic

applications when a RAC Node is taken offline?

• No user downtime

• Zero wait time for WebLogic connection recovery

• Connect pool automatically and rapidly rebalances

• No application changes required


Active GridLink For RAC - Configurability

• Old: Multi Data Source• Enables load balancing with XA

on old RAC versions but….

• Data source (DS) per RAC node

• Map DS to RAC nodes

• Grouped DS into MDS

• Configuration scaling issues

• New: GridLink Data Source• Leverages RAC technology

• Single data source per cluster

• SCAN address

• Simpler

• More scalable

Active GridLink For RAC - Manageability

• GridLink isolates WebLogic

from RAC changes

• Consider adding RAC node

1. Multi Data Source (MDS)• Undeploy MDS

• Add data source 3 on all servers

• Update MDS list

• Redeploy MDS

• Coordinate across servers

2. GridLink• Automatic detection of RAC node

• No WebLogic config changes

• Simpler

• More reliable, no downtime RAC Cluster

Active GridLink For RAC - Performance

• Runtime Connection Load

Balancing (RCLB)• RAC workload aware• Avoid busy RAC nodes

• Multiple apps, backups

• Multi Data Source (MDS)• Round-robin load balancing

• New connections to busy node

• Bottlenecks, performance impact

• GridLink• RCLB distributes runtime

connections to least busy nodes

• Up to 2-3x performance

• More predictable performance RAC Cluster
