Abstract

In an enterprise portal server system having a server, a resource load balancing method and system. The resource load balancing system includes logic for determining threshold load values for optimal performance of the portal server. Current load values in the portal server are intermittently calculated during a load sampling period to determine whether resource overload conditions exist in the portal server during the load sampling period. In one embodiment of the present invention, when resource overload is detected, a load balancing module automatically identifies under utilized resources in the portal server in order to distribute user processes or requests causing the overload conditions from the over utilized resources to the under utilized resources. In one embodiment load balancing conditions are automatically communicated to a system administrator for replicate configuration conditions in the portal server to remote resource connected to the portal server.

Claims

1. A portal server, comprising:

an authentication module for authenticating user credentials for users connecting to said portal server;

a resource sizing module for determining an optimal number of central processing units and memory required by said portal server for optimum performance;

a load detection module for detecting resource usage overload conditions defining a maximum number of concurrent users or user requests processed in said portal server, and

a load balancing module for balancing resource usage overload conditions.

2. The portal server of claim 1, wherein said load balancing module comprises a user request control module for monitoring user requests directories residing in the portal server.

3. The portal server of claim 2, wherein said user request control module further tracks user lookups to directories in said portal server to detect excess access to said directories in order to balance said directories over hardware resources in said portal server.

4. The portal server of claim 3, wherein said load balancing module further comprises a user write request counter module for monitoring user write requests to said hardware resources in said portal server.

5. The portal server of claim 4, wherein said hardware resources further comprise random access memory.

7. The portal server of claim 6, wherein said hardware resources comprise storage disks.

8. The portal server of claim 7, wherein said load balancing module further comprises a system resource balancing module for monitoring resource utilization in said portal server and identifying excess resource capacity in said portal server.

9. The portal server of claim 8, wherein said system resource balancing module further automatically allocates user requests from overloaded resources in said portal server to under utilized resources in said portal server.

10. The portal server of claim 9, wherein said system balancing module further automatically notifies a system administrator of said portal server of an availability of excess resource capacity in order to allow manual resource allocation.

11. The portal server of claim 10, wherein said load balancing module further comprises a resource access control module for monitoring user access requests to said portal server

12. The portal server of claim 11, wherein said resource access control module is automatically selectively enabled and disabled to restrict user access operations to particular resources in said portal server during said particular resources overload conditions.

13. The portal server of claim 12, wherein said load balancing module further comprise a process termination module for monitoring user initiated system processes in said portal server to determine expiration times of said user processes.

14. The portal server of claim 13, wherein said process termination module further terminates expired user processes in said portal server during said resource usage overload conditions in said portal server.

15. The portal server of claim 14, wherein said load balancing module further comprises a load replication module for automatically identifying hardware resources remotely coupled to said portal server to replicate system configurations settings in said hardware resources.

16. A resource load balancing system for balancing resource use overload conditions in a portal server, comprising:

a resource request control unit for controlling user requests to said portal server;

a user write request counter unit for monitoring user write requests to system resources coupled to said portal server; and

an overload balancing condition unit for monitoring said overload conditions in said portal server to automatically generate load balancing signals to a system administrator of said portal server.

17. The resource load balancing system of claim 16, wherein said system resources comprise random access memory.

18. The resource load balancing system of claim 17, wherein said system resources further comprise central processing units.

19. The resource load balancing system of claim 18, wherein said system resources further comprise storage disks.
