Abstract
A method, apparatus, and article of manufacture for dynamically adding functionality to a server. A first operator is received at the server from an attached client, wherein the first operator indicates that new functionality is to be added to the server. A first handler is located for the first operator. The first handler is executed in the server, wherein the first handler registers a second operator associated with the new functionality and installs a second handler for the second operator to perform the new functionality.
Claims38
A method for dynamically adding functionality to a server, comprising the steps of:
- (a) receiving a first operator at the server from an attached client, wherein the first operator indicates that a new functionality is to be added to the server, wherein the new functionality is used to manipulate data stored in a database at the server;
- (b) locating a first handler for the first operator;
- and
- (c) executing the first handler in the server, wherein the first handler registers a second operator associated with the new functionality and installs a second handler for the second operator to perform the new functionality.
