WebSphere Application Server settings for CCRC WAN server
Review IBM®
WebSphere Application
Server settings for the application server profile for the ClearCase®
CCRC WAN
server. If you installed ClearCase into a new profile, the settings in the profile
created during installation have been optimized for best performance. If you installed ClearCase into an existing profile or if the server has
performance problems, the parameter values might require adjustment.
For information about WebSphere Application Server settings and information about modifying the settings, see these resources:
- Tuning performance WebSphere® Application Server documentation: V8.5.
- Search for WebSphere Application Server tuning on IBM developerWorks
The
following table lists the default settings for the WebSphere Application Server profile where the CCRC WAN
server is deployed. These values are applied by
default when the CCRC WAN
server is deployed into
a new profile created during the ClearCase installation or upgrade process.
If the CCRC WAN
server is deployed in an
existing profile with other applications, consider the requirements for all applications
when changing the WebSphere Application Server profile setting.
WebSphere Application Server setting | Default value |
---|---|
Web container > customer properties | com.ibm.ws.webcontainer.channelwriteType=sync |
Web container transport chains > WSInboundDefault > Http inbound channel | Write timeout=300 seconds Persistent timeout=120 seconds |
Process definition > Java Virtual Machine | Initial heap size=1024 MB Maximum heap size=1024MB |
Thread pools | Web Container=300 Default=300 |
Troubleshooting > Logging and Tracing > Diagnostic trace service | Maximum File Size=20MB Maximum number of Historical files=20 |
Modifying application server profile settings for WebSphere Application Server for CCRC WAN server
If the CCRC WAN
server is deployed in an existing
profile, modify the application server profile settings for WebSphere Application Server to match the
default values.
Before you begin
About this task
In a WebSphere Application Server, you can modify tuning parameter values for the application server profile from the WebSphere Application Server administrative console, or use the Wsadmin tool.
These instructions explain how to update the parameter values to the default settings at one time by using the Wsadmin tool command setCMdefaultDefaults . You can also run commands to change specific parameters. For example, use this Wsadmin tool command to change the JVM Heap Size to the default value:setJvmMaxHeapSize 1024
For more information about using the WebSphere Application Server administrative console and the Wsadmin tool, see the WebSphere Application Server documentation: V8.5.
