KB325279: How to increase the Permgen space in Apache Tomcat server for MicroStrategy Web 10.x

SYMPTOM: 
Strategy Web relies heavily on the JVM (Java Virtual Machine) to allocate memory resources and storing the classes and methods used to run Strategy Web. The default values that are used when deploying Strategy Web 10.x JSP may not be enough to handle the different environments (Dev vs. Prod), or the different workloads that each Administrator may need, and can sometimes lead to an error such as the following one:

<record>
 <package>com.Strategy.web.controller</package>
 <level>SEVERE</level>
 <miliseconds>1266853504793</miliseconds>
 <timestamp>02/22/2017 15:45:04:794</timestamp>
 <thread>3</thread>
 <class>GenericWebAppController</class>
 <method>processRequest</method>
 <message>PermGen space (java.lang.OutOfMemoryError)</message>
 <exception>java.lang.OutOfMemoryError: PermGen space
	at java.lang.Class.getDeclaredMethods0(Native Method)
	

 
  
ACTION:
Increase the Permgen space on the JVM that handles the Strategy Web 10.x application.
If using Tomcat 6 and above on a Windows machine, access the Apache Tomcat Monitor > Java, shown below:

Note where it says -XX:MaxPermSize=512M
Under Java Options, include the following statement:

-XX:MaxPermSize=512m

Change the value of 512m to a higher value that suits the needs of the environment. 
 
For more information on PermGen or how to modify this parameter from other Operating Systems, refer to the 3rd party vendor manuals. For Apache Tomcat in Linux, refer to the following article.
