Embodiments of the invention provide systems and methods for applying a patch or a change to a set of binary modules executing on and used by resources of a computing cluster while reducing the downtime of those resources. According to one embodiment, applying a patch to a plurality of binary modules on a computing cluster can comprise identifying resources on one or more of a plurality of nodes of the cluster. Additionally, each of the plurality of binary modules on one or more of the nodes of the cluster can be identified. A graph can be generated logically representing the cluster. Groups within the binary modules and resources can be identified based on the graph. Patches can be applied to the binary modules based on the identified groups. Patching binary modules based on the identified groups can comprise patching all of the binary modules of an identified group together.

Reducing downtime while patching binaries on a cluster

A backoff polling algorithm may use a minimum polling interval which represents an amount of time between repeated polls of a job step queue. When polled, the job step queue may indicate a number of job steps scheduled to execute currently. Additionally, the backoff polling algorithm may repeatedly poll the job step queue at the current polling interval and execute any job steps indicated until the step queue indicates that the number of job steps scheduled to execute currently is below a minimum threshold. While the indicated number of job steps is below the minimum threshold, the backoff polling algorithm may repeatedly increase the polling interval up to a predetermined maximum polling interval and poll at each increased interval until the indicated number of job steps is above the minimum threshold. The backoff polling algorithm may then decrease the polling interval to the minimum polling interval.

A computer ('patch analysis computer') retrieves from a website, metadata describing one or more patch files to be used to change software in one or more computers ('target computers'). Prior to installation of the patch files in a target computer, the patch analysis computer performs analysis on the patch files and on the target computer and on application of the patch files to the target computer. The analysis is based on the retrieved metadata and based on configuration data of the target computer. Subsequent to performing the analysis, the management computer displays a report resulting from the analysis including one or more operations to fix issues found during analysis, and receives input from a human on specific patch files and operations. In response to receipt of human input, the patch analysis computer performs operations approved by the human and applies the patch files to the target computer.

Change analysis on enterprise systems prior to deployment

Some embodiments of the present invention provide a system that maintains a software system. During operation, the system obtains a compliance policy for the software system and monitors the software system for a violation of the compliance policy. If such a violation is detected, the system retrieves a change package associated with the violation based on the compliance policy and automatically deploys the change package to the software system to resolve the violation.

Automated compliance policy enforcement in software systems

Some embodiments of the present invention provide a system for maintaining a software system. During operation, the system obtains a compliance policy for the software system and monitors the software system for a violation of the compliance policy. If a violation is detected, the system generates a change recommendation associated with the violation using the compliance policy and provides the change recommendation to an administrator, so that the administrator can use the change recommendation to resolve the violation.
