Title:
SYSTEM FOR DYNAMIC LOAD OF SHARED LIBRARY AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3314378
Kind Code:
B2
Abstract:
PURPOSE: To provide a mechanism for dynamically loading executable library objects only when the execution of those libraries is requested.
CONSTITUTION: In the dynamic load of executable library objects, the overhead of an operating system and necessary memory areas can be reduced by delaying the load of the objects until object reference is requested. In initial task loading, only main execution and the library objects refereed to by the execution are assigned, and secondary reference objects are not assigned. The object reference generates page absence for a page to which the objects are assigned and not loaded. A page absence processing generates the loading of the executable objects and address rearrangement. A shared memory system permits the sharing of the executable objects until the objects are specifically referred to.
