Abstract

Methods and apparatus, including computer program products, are provided for transitioning components of a static cluster system to a dynamic cluster system. In one aspect, there is provided a computer-implemented method. The method may include selecting, at a user interface, a static cluster system to transition one or more components of the selected static cluster system to a dynamic cluster system. At least one install agent may be provided to the selected static cluster system. The install agent may be configured to install one or more agents outside of the selected static cluster system. The one or more agents may be configured to move the one or more components from the selected static cluster system to a dynamic cluster system. Related apparatus, systems, methods, and articles are also described.

Claims

1. A computer-implemented method comprising:

selecting a static cluster to transition one or more nodes of the selected static cluster to a dynamic cluster; and

providing to each node of the selected static cluster at least one install agent within the selected static cluster, the at least one install agent configured to install one or more agents outside of the selected static cluster, the one or more installed agents configured to move the one or more nodes from the selected static cluster to the dynamic cluster.

2. The computer-implemented method of claim 1, wherein providing further comprises:

providing the at least one install agent as a software upgrade or a patch to a management software of the static cluster.

3. The computer-implemented method of claim 1, wherein providing further comprises:

installing the one or more agents outside of the selected static cluster by installing the one or more agents in a processor not being moved.

4. The computer-implemented method of claim 1 further comprising:

selecting, at a user interface, the static cluster from a list of a plurality of static clusters.

5. The computer-implemented method of claim 1 further comprising:

moving, by the one or more installed agents, the one or more nodes of the selected static cluster to the dynamic cluster.

6. The computer-implemented method of claim 5 further comprising:

initiating, by the one or more installed agents, a shutdown of the selected static cluster, when the one or more agents move the one or more installed nodes, the one or more nodes including an application server and a central instance.

7. The computer-implemented method of claim 6 further comprising:

initiating, by the one or more installed agents, a start of the dynamic cluster, wherein the one or more installed agents operate outside of the static cluster by operating on a processor not being transitioned.

8. The computer-implemented method of claim 1 further comprising:

configuring the one or more installed agents to include a first location of the one or more nodes at the selected static cluster and a second location of a central storage location at the dynamic cluster.

9. A non-transitory computer-readable medium containing instructions to configure at least one processor to perform a method, the method comprising:

selecting a static cluster to transition one or more nodes of the selected static cluster to a dynamic cluster; and

providing to each node of the selected static cluster at least one install agent within the selected static cluster, the at least one install agent configured to install one or more agents outside of the selected static cluster, the one or more installed agents configured to move the one or more nodes from the selected static cluster to the dynamic cluster.

10. The non-transitory computer-readable medium of claim 9, wherein providing further comprises:

providing the at least one install agent as a software upgrade or a patch to a management software of the static cluster.

11. The non-transitory computer-readable medium of claim 9, wherein providing further comprises:

installing the one or more agents outside of the selected static cluster by installing the one or more agents in a processor not being moved.

12. The non-transitory computer-readable medium of claim 9 further comprising:

selecting, at a user interface, the static cluster from a list of a plurality of static cluster.

13. The non-transitory computer-readable medium of claim 9 further comprising:

moving, by the one or more installed agents, the one or more nodes of the selected static cluster to the dynamic cluster.

14. The non-transitory computer-readable medium of claim 13 further comprising:

initiating, by the one or more installed agents, a shutdown of the selected static cluster, when the one or more agents move the one or more nodes.

15. The non-transitory computer-readable medium of claim 14 further comprising:

initiating, by the one or more installed agents, a start of the dynamic cluster.

16. The non-transitory computer-readable medium method of claim 9 further comprising:

configuring the one or more installed agents to include a first location of the one or more nodes at the selected static cluster and a second location of a central storage location at the dynamic cluster.

17. A system comprising:

at least one processor; and

at least one memory, wherein the at least one processor and the at least one memory are configured to perform a method comprising;

selecting a static cluster to transition one or more nodes of the selected static cluster to a dynamic cluster; and

providing to each node of the selected static cluster system at least one install agent within the selected static cluster, the at least one install agent configured to install one or more agents outside of the selected static cluster, the one or more installed agents configured to move the one or more nodes from the selected static cluster to the dynamic cluster.

18. The system of claim 17 further comprising:

selecting, at a user interface, the static cluster from a list of a plurality of static clusters.

19. The system of claim 17 further comprising:

moving, by the one or more installed agents, the one or more nodes of the selected static cluster to the dynamic cluster.

20. The system of claim 19 further comprising:

initiating, by the one or more installed agents, a shutdown of the selected static cluster, when the one or more agents move the one or more nodes.
