Abstract

A method, apparatus and computer instructions are disclosed for maintaining the compatibility of a multiple nodes in a distributed systems management environment with multiple configuration settings, by transforming the configuration data stored in the master repository (one possible realization is where XML documents contain the configuration data) from one version of the product to a previous version of the product. For multiple versions of the systems management environment, a transformation pipeline process (one possible realization of such a process may utilize XSLT) can be used by a “master” node to transform the configuration data multiple times for each version of the environment, until the configuration data has the format of the intended recipient “slave” node. Also, by performing the transformation process on the “master” side of the computing environment, “slave” nodes with older version configuration settings can continue to operate without having to upgrade their software applications in this regard.

Claims

1. An apparatus to maintain compatibility between nodes within a distributed systems management environment, comprising:

a master node, said master node including a primary storage area, said primary storage area including at least two primary storage sections; and

a plurality of slave nodes, each slave node of said plurality of slave nodes configured with a plurality of configuration settings having a first format, and each slave node of said plurality of slave nodes including a secondary storage area,

wherein said master node is configured to;

read said plurality of configuration settings having said first format from a first primary storage section of said at least two primary storage sections;

transform said plurality of configuration settings having said first format to a plurality of configuration settings having a second format;

write said plurality of configuration settings having said second format to a second primary storage section of said at least two primary storage sections; and

convey said plurality of configuration settings having said second format from said primary storage section to each said secondary storage area of said plurality of slave nodes, wherein said convey operation comprises a synch out operation; and

wherein each said slave node of said plurality of secondary slave nodes is configured to;

receive said plurality of configuration settings having said second format; and

reconfigure in accordance with said plurality of configuration settings having said second format,

wherein said first format comprises a WebSphere version 5.x format, and said second format comprises a WebSphere 6.x format, and further wherein said plurality of configuration settings having said first format comprises at least one 5.x XSL schema document, and said plurality of configuration settings having said second format comprises at least one 6.x XSL schema document.

2. The apparatus of claim 1, wherein said primary storage area comprises a master repository, and said secondary storage area comprises a node repository.

3. The apparatus of claim 1, wherein said master node and said plurality of slave nodes comprise a plurality of data processing units.

4. The apparatus of claim 1, wherein said master node and said plurality of slave nodes comprise a plurality of servers.
