System and method for managing resources of applications and threads performed on java virtual machine

A resource management system for managing resources related to a Java Virtual Machine (JVM) and an application executed in the JVM, the resource management system comprising:

• a resource consumer management unit which generates a resource consumer for each of threads, wherein the resource consumer uses a resource;
• and
• a resource allocation policy manager which defines a resource identifier enabling an arbitrary resource to be uniquely identified, generates one or more resource manager for each resource identifier, wherein the at least one resource manager manages a resource, and sets a resource usage quota related to a resource identifier and a resource consumer, according to a request by the resource consumer management unit;
• wherein the resource manager calculates a quantity of resource usage by resource consumers generated for all applications and threads in the applications, stores the calculated quantity of resource usage, and informs about the quantity of resource usage.

A method of managing resources when an application is generated in a containment framework comprising a resource management system related to a Java Virtual Machine (JVM) and an application executed in the JVM, the method comprising:

• generating a unique identifier related to an application that is to be executed;
• storing the unique identifier;
• setting a resource allocation policy calling a resource identifier that is in an initial array position of a list in which resource identifiers uniquely identifying resources are arrayed;
• if the resource identifier exists in the initial array position, generating a resource manager related to the resource identifier that is a resource, setting a maximum usage value that is a quota related to the generated resource manager, registering the resource manager in a resource manager registry in which registered resource managers are stored according to types, and storing information on the generated resource manager and application identifier;
• and
• starting an application, and changing a state of the application according to a lifecycle of the application.

A method of managing resources of threads by treating all of the threads performed in a Java Virtual Machine (JVM) as resource consumers, the method comprising:

• generating modified JVM threads related to the threads;
• wherein the generating the modified JVM threads comprises:
• calling a start( )method of a certain thread object;
• requesting resource consumer object allocation for the certain thread object;
• generating a new resource consumer object according to the request, and obtaining an identifier of an application in which the certain thread object belongs;
• transferring to a resource allocation policy manager information on the generated new resource consumer object and the application identifier, and requesting setting of a resource allocation policy for a corresponding resource consumer;
• and
• if the setting of the resource allocation policy for the corresponding resource consumer is ended, performing a run( )function of the thread object and generating a native thread.
