Enable Domain-Level Enhancements

Language:

Log in to the Oracle WebLogic Server Administration Console.

Select Domain name in the left navigation pane.

Click the General tab.

In your domain home page, select Enable Exalogic Optimizations, and click Save.

Activate changes.

Stop and start your domain.

The Enable Exalogic Optimizations setting collectively enables all of the individual features described in this table. The Startup Option indicates how to independently enable and disable each feature.

Feature	Options	Description
Scattered Reads	Description	Increased efficiency during I/O in environments with high network throughput
	Startup Option	`-Dweblogic.ScatteredReadsEnabled=true/false`
	MBean	`KernelMBean.setScatteredReadsEnabled`
Gathered Writes	Description	Increased efficiency during I/O in environments with high network throughput
	Startup Option	`-Dweblogic.GatheredWritesEnabled=true/false`
	MBean	`KernelMBean.setGatheredWritesEnabled`
Lazy Deserialization	Description	Increased efficiency with session replication
	Startup Option	`-Dweblogic.replication.enableLazyDeserialization=true/false`
	MBean	`ClusterMBean.setSessionLazyDeserializationEnabled`
