Starting with vCenter Server 5.1, VMware Tomcat Server settings can no longer be configured through the Windows user interface. vCenter Server versions 5.1 and later use VMware vCenter Server - tc Server, an enterprise version of Apache Tomcat 7. 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 Inventory Service, and Profile-Driven Storage Service. For JVM heap size recommendations, see Hardware Requirements for vCenter Server, the vSphere Web Client, vCenter Inventory Service, and vCenter Single Sign-On.

Settings for Java options are stored in the following files.

  • vCenter Server. installation_directory\VMware\Infrastructure\tomcat\conf\wrapper.conf

  • vCenter Inventory Service. installation_directory\VMware\Infrastructure\Inventory Service\conf\wrapper.conf

  • Profile-Driven Storage Service. installation_directory\VMware\Infrastructure\Profile-Driven Storage\conf\wrapper.conf

  • The vSphere Web Client. installation_directory\VMware\vSphereWebClient\server\bin\service\conf\wrapper.conf

Table 1. Inventory Service and Profile-Driven Storage Service Java Maximum JVM Heap Size Setting in the wrapper.conf Files

Java Option

Setting and Default Value


The maximum JVM heap size, in megabytes. This setting controls the maximum size of the Java heap. Tuning this parameter can reduce the overhead of garbage collection, improving server response time and throughput. For some applications, the default setting for this option is too low, resulting in a high number of minor garbage collections.

vCenter Server Port or Security Setting

Setting and Default Value

Base shutdown port


Base JMX port. The listener implemented by the com.springsource.tcserver.serviceability.rmi.JmxSocketListener class is specific to tc Server. This listener enables JMX management of tc Server, and is the JMX configuration that the AMS management console uses to manage tc Server instances. The port attribute specifies the port of the JMX server that management products, such as AMS, connect to. The variable ${jmx.port} is set to 6969 in the default file. The bind attribute specifies the host of the JMX server. By default, this attribute is set to the localhost (

The default -1 setting disables the port.
