Abstract

The invention provides methods of placing programmatic packages in a clustered environment. An exemplary method of placing programmatic packages in response to a state change in a clustered computing system is presented including: receiving the state change; in response to receiving the state change, ordering programmatic packages, where each of the programmatic packages is configured with a package priority, the package priority representing a user designated assignment of programmatic importance from high to low; placing the programmatic package having a highest package priority on a configured node, the configured node included as part of the clustered computing system; and for each of a remaining programmatic packages, placing each of the remaining programmatic packages on a node set in accordance with a user-specified package dependency, the node set included as part of the clustered computing system.

Claims

1. A method of placing at least one programmatic package in response to a state change in a clustered computing system comprising:

receiving the state change;

in response to the receiving the state change,

ordering the at least one programmatic packages, each of the at least one programmatic packages configured with a package priority, the package priority representing a user designated assignment of programmatic importance from high to low;

placing the at least one programmatic package having a highest package priority on a configured node, the configured node included as part of the clustered computing system; and

for each of a remaining of the at least one programmatic packages,

placing each of the remaining of the at least one programmatic packages on a node set in accordance with a user-specified package dependency, the node set included as part of the clustered computing system.

2. The method of claim 1 wherein the state change is selected from the group consisting of:

a package failure, a node failure, a cluster failure, a system failure, a hardware failure, a software failure, a network failure, a system command, and a state change command.

3. The method of claim 1 further comprising assigning a user-specified package dependency to each of the at least one programmatic package.

4. The method of claim 3 wherein the user-specified package dependencies are selected from the group consisting of:

a same node exclusion dependency, an all node exclusion dependency, a same node up dependency, an any node up dependency, and a different node up dependency.

5. A method of dragging a first programmatic package in response to a placement of a second programmatic package, the second programmatic package configured with a user-specified package dependency:

determining a first package priority corresponding to the first programmatic package;

determining a second package priority corresponding to the second programmatic package;

if the first package priority is lower than the second package priority, and if the first programmatic package is not running, then

dragging the first programmatic package to a first node in accordance with the user-specified package dependency.

6. The method of claim 5 further comprising:

if the first package priority is lower than the second package priority, and if the first programmatic package is running on a second node, then

dragging the first programmatic package to the first node in accordance with the user-specified package dependency.

7. The method of claim 6 wherein the dragging the first programmatic package to the first node comprises:

if the first programmatic package is running on the second node, halting the first programmatic package on the second node;

placing the first programmatic package on the first node in accordance with the user specified programmatic package; and

starting the first programmatic package on the first node.

8. The method of claim 5 wherein the user-specified package dependency is selected from the group consisting of:

a same node exclusion dependency, an all node exclusion dependency, a same node up dependency, an any node up dependency, and a different node up dependency.

9. The method of claim 5 wherein the configured node is associated with a node set in a clustered computing system.

10. A system for placing and dragging at least two programmatic packages in a clustered computing system comprising:

a configuration module for assigning a package priority and a user-specified package dependency to each of the at least two programmatic packages;

a placement module for placing the at least two programmatic packages in accordance with the package priority and the user-specified package dependency, the user-specified package dependency

a dragging module for dragging one of the at least two programmatic packages in accordance with the package priority and the user-specified package dependency.

11. The system of claim 10 further comprising:

a create action module for halting and starting the at least two programmatic packages.

12. The system of claim 10 wherein the user-specified package dependency is selected from the group consisting of:

a same node exclusion dependency, an all node exclusion dependency, a same node up dependency, an any node up dependency, and a different node up dependency.

13. A computer program product for use in conjunction with a computer system for placing at least one programmatic package in response to a state change in a clustered computing system comprising:

instructions for receiving the state change;

in response to the receiving the state change,

instructions for ordering the at least one programmatic packages, each of the at least one programmatic packages configured with a package priority, the package priority representing a user designated assignment of programmatic importance from high to low;

instructions for placing the at least one programmatic package having a highest package priority on a configured node, the configured node included as part of the clustered computing system; and

for each of a remaining of the at least one programmatic packages,

instructions for placing each of the remaining of the at least one programmatic packages on a node set in accordance with a user-specified package dependency, the node set included as part of the clustered computing system.

14. The computer program product of claim 13 wherein the state change is selected from the group consisting of:

a package failure, a node failure, a cluster failure, a system failure, a hardware failure, a software failure, a network failure, a system command, and a state change command.

15. The computer program product of claim 13 further comprising instructions for assigning a user-specified package dependency to each of the at least one programmatic package.

16. The computer program product of claim 15 wherein the user-specified package dependencies are selected from the group consisting of:

a same node exclusion dependency, an all node exclusion dependency, a same node up dependency, an any node up dependency, and a different node up dependency.

17. A computer program product for use in conjunction with a computer system for dragging a first programmatic package in response to a placement of a second programmatic package, the second programmatic package configured with a user-specified package dependency:

instructions for determining a first package priority corresponding to the first programmatic package;

instructions for determining a second package priority corresponding to the second programmatic package;

if the first package priority is lower than the second package priority, and if the first programmatic package is not running, then

instructions for dragging the first programmatic package to a first node in accordance with the user-specified package dependency.

18. The computer program product of claim 17 further comprising:

if the first package priority is lower than the second package priority, and if the first programmatic package is running on a second node, then

instructions for dragging the first programmatic package to the first node in accordance with the user-specified package dependency.

19. The computer program product of claim 18 wherein the instructions for dragging the first programmatic package to the first node comprises:

if the first programmatic package is running on the second node, instructions for halting the first programmatic package on the second node;

instructions for placing the first programmatic package on the first node in accordance with the user specified programmatic package; and

instructions for starting the first programmatic package on the first node.

20. The computer program product of claim 17 wherein the user-specified package dependency is selected from the group consisting of:

a same node exclusion dependency, an all node exclusion dependency, a same node up dependency, an any node up dependency, and a different node up dependency.
