Starting with vCenter Server 5.1, VMware Tomcat Server settings can no longer be configured using the Windows user interface at

VMware Tomcat.
vCenter Server 5.1 uses VMware vFabric tc Server, an enterprise version of Apache Tomcat 7. Unlike Tomcat version 6, which is used with earlier versions of vCenter Server, Tomcat version 7 does not provide a control panel in the Windows user interface. Instead, you configure Tomcat by editing configuration files manually.
You can adjust the JVM maximum heap size for vCenter Server, vCenter Single Sign-On, vCenter Inventory Service, and Profile-Driven Storage Service.
This table provides the JVM heap size recommendations:
vCenter Server 5.1: vCenter Server Inventory | VMware VirtualCenter Management Webservices (tc Server) | Inventory Service | Profile-Driven Storage Service |
Small inventory (1-100 hosts or 1-1000 virtual machines) | 1 GB | 3 GB | 512 MB |
Medium inventory (100-400 hosts or 1000-4000 virtual machines) | 2 GB | 6 GB | 1 GB |
Large inventory (More than 400 hosts or 4000 virtual machines) | 3 GB | 12 GB | 2 GB |
vCenter Server 5.5: vCenter Server Inventory | VMware VirtualCenter Management Webservices (tc Server) | Inventory Service | Profile-Driven Storage Service |
Small inventory (1-100 hosts or 1-1000 virtual machines) | 512 MB | 3 GB | 1 GB |
Medium inventory (100-400 hosts or 1000-4000 virtual machines) | 512 MB | 6 GB | 2 GB |
Large inventory (More than 400 hosts or 4000 virtual machines) | 1 GB | 12 GB | 4 GB
|
Note: After adjusting the JVM heap size in the
wrapper.conf
file, VMware recommends restarting the VirtualCenter Management Web services. For more information, see
Stopping, starting, or restarting vCenter services (1003895).
