Abstract

In accordance with an embodiment, described herein is a system and method for supporting multiple partitions and edit sessions in a multitenant application server environment. In accordance with an embodiment, a first administrator or user can obtain a named edit session for use with a partition, make changes, and then activate those changes. Another administrator or user can create a named edit session in parallel. If there are conflicts between a concurrent change and changes being made by another user, the administrator will receive an error when activating the changes. At that point, the administrator can resolve the conflicts and activate the changes. Upon activation, the changes in the edit session will be applied to a global edit configuration.

Claims

1. A system for supporting multiple edit sessions in a multitenant application server environment, comprising:

one or more computers, each including one or more microprocessors;

an application server environment on the computers, wherein the application server environment includes a domain with one or more partitions, and a domain configuration that configures the domain and the one or more partitions;

a management API that includes a plurality of methods for use in changing the domain configuration;

a plurality of concurrent edit sessions, wherein each concurrent edit session is established to edit a snapshot of the domain configuration; and

a concurrent session manager in the domain, wherein the concurrent session manager operates to detect conflicts in changes made by the plurality of concurrent edit sessions, and provide an alert to an administrator.

2. The system of claim 1, wherein the concurrent session manager detects the conflicts by perform the steps of:

determining a first difference between the domain configuration and changes made by an administrator to a snapshot of the domain configuration;

determining a second difference between the snapshot of the domain configuration and the domain configuration; and

comparing the first and second differences.

3. The system of claim 1, wherein the administrator is a system administrator and each of the plurality of edit sessions is started by a different system administrator.

4. The system of claim 1, wherein each of the plurality of concurrent edit sessions is started by a different partition administrator.

5. The system of claim 1, where each of the plurality of concurrent edit sessions are started by a system administrator and a partition administrator.

6. The system of claim 1, wherein the concurrent session manager is invoked when the administrator performs an activate action using the management API to merge changes made by the administrator to the domain configuration.

7. The system of claim 6, wherein the administrator performs a resolve action using the management API after viewing the displayed conflicts, and performs an activate action using the management API.

8. The system of claim 6, wherein the changes made by the administrator are merged into the domain configuration if no conflicts are detected.

9. The system of claim 1, wherein the snapshot is persisted to a storage for use in detecting the conflicts by the concurrent session manager.

10. The system of claim 9, wherein the persisting of the snapshot occurs when an administrator associated with the snapshot performs an activate action.

11. A method for supporting multiple partitions and edit sessions in a multitenant application server environment, comprising:

providing an application server environment on one or more computers, wherein the application server environment includes a domain with one or more partitions, a domain configuration that configures the domain and the partitions, a management API for use in changing the domain configuration;

receiving, via the management API, changes from a plurality of concurrent edit sessions, wherein each concurrent edit session is established to edit a snapshot of the domain configuration;

detecting conflicts in the received changes; and

alerting an administrator for resolution of the conflicts.

12. The method of claim 11, wherein the concurrent session manager detects the conflicts by perform the steps of:

determining a first difference between the domain configuration and changes made by an administrator to a snapshot of the domain configuration;

determining a second difference between the snapshot of the domain configuration and the domain configuration; and

comparing the first and second differences.

13. The method of claim 12, wherein the administrator is selected from the group consisting of a system administrator, and a partition administrator.

14. The method of claim 12, wherein each of the plurality of concurrent edit sessions is started by a different partition administrator, or by a different system administrator.

15. The method of claim 12, where the plurality of concurrent edit sessions are started by a system administrator and a partition administrator.

16. The method of claim 12, wherein the concurrent session manager is invoked when the administrator performs an activate action using the management API to merge changes made by the administrator to the domain configuration.

17. The method of claim 16, wherein the administrator performs a resolve action using the management API after viewing the displayed conflicts, and performs an activate action again using the management API.

18. The method of claim 16, wherein the changes made by the administrator is merged into the domain configuration if no conflicts are detected.

19. The method of claim 12, wherein the snapshot is persisted to a storage for use in detecting the conflicts by the concurrent session manager.

20. A non-transitory computer readable storage medium, including instructions stored thereon which when read and executed by one or more computers cause the one or more computers to perform the steps comprising:

configuring an application server environment on one or more computers to include a domain with one or more partitions, a domain configuration that configures the domain and the partitions;

receiving, via a management API, changes from a plurality of concurrent edit sessions, wherein each concurrent edit session is established to edit a snapshot of the domain configuration;

detecting conflicts in the received changes; and

alerting an administrator for resolution of the conflicts.
