9. ON24: Quality of Service – Challenge I
 WebLogic Cluster hosts
multiple web applications
 WebLogic Servers are uniformly
processing a variety of different
transaction and request types
 Challenge providing the highest
quality uninterruptable service:
 Difficult to tune WebLogic servers
for best performance and stability.
 High levels of JVM memory
fragmentation.
 Long GC pauses, hard to control
Page 9 | © 2011 ON24, Inc. All rights reserved. | ON24, Inc. Confidential

10. ON24: Quality of Service – Challenge II
 Live traffic occasionally need to
be switched from primary
cluster into a backup cluster:
 Scheduled upgrades
 Product releases
 Other reasons
 Active sessions in primary are
isolated from backup cluster:
 Short interruption of the service
 Major inconvenience for a 24x7
SaaS platform and its users
 Planning for and accommodating
these disruptions are time
consuming and labor intensive
Page 10 | © 2011 ON24, Inc. All rights reserved. | ON24, Inc. Confidential

11. ON24: Quality of Service – Solution I
 Reduce JVM fragmentation:
 Load Balancer segregates traffic
 WebLogic servers are grouped
into individual pools that process
homogenous traffic
 Low JVM heap fragmentation and
predictable short GC pauses
 This creates problem with HTTP
session stickiness
 Centralize HTTP sessions storage
 Coherence*Web stores HTTP
sessions on the application grid
 Any application grid member can
access related HTTP session
Page 11 | © 2011 ON24, Inc. All rights reserved. | ON24, Inc. Confidential

12. ON24: Quality of Service – Solution I Extra
 Further segregate traffic
 Use multiple active clusters
 Separate primary traffic from
specialty requests, such as:
 Reporting / Searches
 Data Warehouse updates
 Other Utility tasks
 Individually tune clusters
 Traffic specific tuning
 Appropriate sizing
 Dynamically add/remove
active clusters in real time:
 No service interruptions
 Transparent to users
Page 12 | © 2011 ON24, Inc. All rights reserved. | ON24, Inc. Confidential

13. ON24: Quality of Service – Solution II
 Transparent switch of
live traffic
 Application grid running
Coherence*Web is shared
between two clusters
 Active HTTP session are
accessible from both
clusters
 Rolling traffic from primary
cluster into a backup does
not degrade performance
