C Configuring a large-scale CloudSystem deployment
In a large-scale deployment, CloudSystem Foundation can manage over 4,000 virtual machine
instances. To support this type of deployment, HP recommends that you update the maximum heap
size parameter of the jetty-Atlas Java web server on the Foundation base appliance.
The best practice is to perform the procedure in this section after the Foundation base appliance
is successfully deployed using cssstart, and before CloudSystem is made available for use by
end users.
See also“Working with the csadmin CLI” in the HP CloudSystem 8.0 Administrator Guide at
Enterprise Information Library.
Prerequisites
• Minimum required privileges: Infrastructure administrator
• The csadmin CLI package is installed on the CloudSystem Foundation base appliance.
Procedure 30 Updating the maximum heap size of the jetty-Atlas Java web server
1. From the csadmin CLI, enable the cloudadmin user access on the Foundation base appliance.
2. Open the VNC Console terminal window to the Foundation base appliance.
3. Log in as the cloudadmin user.
4. Change the maximum heap size for the jetty-Atlas Java web server from –Xmx512m to
–Xmx750m.
Example:
[cloudadmin@Basehost ~]$ sudo vi /ci/etc/jvm.d/jetty-Atlas
[cloudadmin@Basehost ~]$ cat /ci/etc/jvm.d/jetty-Atlas
-Xss256k
-Xms256m
-Xmx750m
-XX:PermSize=128m
-XX:ReservedCodeCacheSize=32m
-XX:+UseCompressedOops
-verbose:gc
-XX:+PrintGCDetails
-Xloggc:/ci/jetty-Atlas/logs/gc.log
-XX:+UseGCLogFileRotation
-XX:NumberOfGCLogFiles=2
-XX:GCLogFileSize=1m
5. Save the changes.
6. Restart the jetty-Atlas Java web server using the following command:
[cloudadmin@Basehost ~]$ sudo crm resource restart JettyAtlas
