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, performed by a computer system, a state change, wherein the state change is selected from a 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;

in response to the receiving the state change,

ordering, performed by the computer system, 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;

assigning a user-specified package dependency selected from a 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 to each of the at least one programmatic package, wherein the user-specified package dependency specifies a dependency between two or more programmatic packages with respect to one or more nodes in the clustered computing system, wherein all nodes in the clustered computing system behave like a single computer by working together;

placing, performed by the computer system, 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, performed by the computer system, 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. A non-transitory computer readable storage medium having computer-readable program instructions stored thereon 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, the computer program product comprising:

instructions for receiving a state change, wherein the state change is selected from a 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;

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 selected from a 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, the node set included as part of the clustered computing system, wherein the user-specified package dependency specifies a dependency between two or more programmatic packages with respect to one or more nodes in the clustered computing system, wherein all nodes in the clustered computing system behave like a single computer by working together.
