Abstract

In embodiments, the present invention provides mechanisms and methods for making a plurality of configuration changes to a set of servers comprised of an administration server and one or more managed servers. These mechanisms and methods can enable a number of changes to be made to the configuration at once, i.e., in a batch. The ability of an administrator to make a number of changes to the configuration, validate the changes and then persist the changes to the servers is termed a “transaction based” change process. In such transaction based processing, embodiments process changes in batches, which enables embodiments to avoid failures in configuration changes that result in the machines being in a non-recoverable or unknown configuration state.

Claims

1. A method for performing a set of configuration changes to a set of servers in a transaction based change process, comprising the steps of:

a) receiving a set of changes to a configuration;

b) creating a configuration file update including the set of changes;

c) distributing the configuration file update to a select set of servers, wherein the select set of servers includes two or more servers;

d) determining whether to apply the set of changes to the select set of servers, wherein each server that receives the configuration file update performs the steps of

reading the set of changes into a managed bean, wherein the managed bean also contains configuration information of the server where the managed bean resides,

comparing the configuration file update to the configuration information of the server,

storing any differences between the configuration file update and the configuration information in a list of events, and

determining whether the server is able to accept the set of changes, wherein the set of changes are acceptable if applying the differences stored in the list of events does not cause the server to enter into an error state;

e) receiving responses from each server in the select set of servers as to whether the servers are able to accept the set of changes;

f) activating the set of changes on the select set of servers if the responses from the select set of servers indicate that all of the select set of servers are able to accept the set of changes; and

g) generating a further set of changes and repeating steps c, d, e, and f if the responses from the select set of servers indicate that at least one of the select set of servers is not able to accept the set of changes.

2. The method of claim 1, wherein activating the changes on the select set of servers further comprises:

automatically rebooting the select set of servers so that the set of changes are made effective.

3. The method of claim 1, wherein a first change is nested within a second change by issuing an edit/save combination within a context of an existing edit.

4. The method of claim 3, wherein completion of a nested change does not result in persistence of the nested change.

5. The method of claim 1, wherein a change is made to the configuration by a first call to edit and subsequently a first call to save.

6. The method of claim 5, wherein a first change is nested within a second change by a second call to edit before the first call to save.

7. The method of claim 1, wherein the set of changes are tracked based on user identity.

8. The method of claim 7, wherein if two or more administrators log in with the same user identity, the set of changes made by the two or more administrators are collected into a single set of changes.

9. The method of claim 1, wherein a server receiving the configuration file update validates the configuration file update by comparing the configuration file update to one or more configuration MBeans.

10. The method of claim 9, wherein the one or more configuration MBeans are associated with a running state of a server from the select set of servers.

11. The method of claim 9, wherein the one or more configuration MBeans are related to one another in an MBean graph.

12. The method of claim 9, wherein comparing the configuration file update to the one or more configuration MBeans is performed using a MBean tree differencing mechanism, wherein a persisted configuration is retrieved into the one or more MBeans related to one another by a graph, tree, or similar data structure.

13. The method of claim 9, wherein comparing the configuration file update to the one or more configuration MBeans comprises:

reading the configuration file update into an MBean graph;

performing a depth first traversal of the MBean graph starting at the root node of the MBean graph;

for each MBean node, comparing primitives of the MBean node with a current configuration stored at the managed server; and

storing changes in a list of events, which may be played against the current configuration MBean graph to yield an updated configuration MBean graph.

14. The method of claim 1, wherein the configuration file update includes an entire configuration with updates applied.

15. The method of claim 1, wherein the set of changes are received at a working version of the configuration.

16. The method of claim 1, wherein multiple users can sequentially edit the set of changes to the configuration.

17. The method of claim 1, wherein the further set of changes can be the set of changes that were received in step a or a different set of changes.

18. A computer-readable storage medium storing one or more sequences of instructions for performing a set of configuration changes to a set of servers in a transaction based change process, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:

a) receiving a set of changes to a configuration;

b) creating a configuration file update including the set of changes;

c) distributing the configuration file update to a select set of servers, wherein the select set of servers includes two or more servers;

d) determining whether to apply the set of changes to the select set of servers, wherein each server that receives the configuration file update performs the steps of

reading the set of changes into a managed bean, wherein the managed bean also contains configuration information of the server where the managed bean resides,

comparing the configuration file update to the configuration information of the server,

storing any differences between the configuration file update and the configuration information in a list of events, and

determining whether the server is able to accept the set of changes, wherein the set of changes are acceptable if applying the differences stored in the list of events does not cause the server to enter into an error state;

e) receiving responses from each server in the select set of servers as to whether the servers are able to accept the set of changes;

f) activating the set of changes on the select set of servers if the responses from the select set of servers indicate that all of the select set of servers are able to accept the set of changes; and

g) generating a further set of changes and repeating steps c, d, e, and f if the responses from the select set of servers indicate that at least one of the select set of servers is not able to accept the set of changes.

19. A system for performing a set of configuration changes to a set of servers in a transaction based change process, comprising:

a server, including one or more processors, which receives a set of changes to a configuration; and

one or more stored sequences of instructions which, when executed by the one or more processors, cause the processor to carry out the steps of;

a) receiving the set of changes to the configuration;

b) creating a configuration file update including the set of changes;

c) distributing the configuration file update to a select set of servers, wherein the select set of servers includes two or more servers;

d) determining whether to apply the set of changes to the select set of servers, wherein each server that receives the configuration file update performs the steps of

reading the set of changes into a managed bean, wherein the managed bean also contains configuration information of the server where the managed bean resides,

comparing the configuration file update to the configuration information of the server,

storing any differences between the configuration file update and the configuration information in a list of events, and

determining whether the server is able to accept the set of changes, wherein the set of changes are acceptable if applying the differences stored in the list of events does not cause the server to enter into an error state;

e) receiving responses from each server in the select set of servers as to whether the servers are able to accept the set of changes;

f) activating the set of changes on the select set of servers if the responses from the select set of servers indicate that all of the select set of servers are able to accept the set of changes; and

g) generating a further set of changes and repeating steps c, d, e, and f if the responses from the select set of servers indicate that at least one of the select set of servers is not able to accept the set of changes.
