Database, Java, Agent or NETWORK?

For Cloud, network waits have been experienced due to firewall, DNS resolution and network
misconfigurations. Inspecting waits via the Page Performance is important!

Load Balancers
Oracle Confidential 30

29. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. |
Why a Load Balancer?
Load Balancer setup and configuration
– Users require session affinity to a particular OMS
This allows for new connections to perform Round-Robin vs. Most Requested
which is less efficient.
Allows for simpler scaling for environments to support future growth.

This is your pain point as a DBA- network waits due to misconfigurations, DNS resolution failures
and other network features that may impact successful connectivity. By removing these waits and
implementing HA, we create a continual service and high performing cloud environment.

High Availability to the Cloud
Ability to Associate Multiple Gateways with Agents
First Gateway becomes “Primary” Gateway, Subsequent become Secondary
Gateways.
If the Primary becomes Unavailable, one of the Secondary's Takes over as
the Primary by Proxy. If the Secondary become Unavailable, Next Secondary
takes over and so on, so forth.
