Abstract

Mechanisms for enforcing change control in operations performed by operational management products (OMPs) are provided. The mechanisms automate the checking of a request-for-change (RFC) state by an OMP when the OMP is installed in an environment where a change management database (CMDB) has been installed and certain resources or operations have been placed under strict change control. The OMPs of the illustrative embodiments require an RFC identifier to be specified when a change operation of the OMP is invoked. The RFC identifier is used by the OMP to access a service management system so that the OMP may determine if the RFC identifier is valid, IT resources are in the correct state, and the change is scheduled to be performed at the current time. If these checks are passed, then the change operation associated with the RFC is permitted to occur.

Claims

1. A method, in a computing system, for performing automated change control on one or more data processing system resources, comprising:

receiving, in the computing system, a change operation command specifying an operation for changing a configuration of a resource in a data processing system;

automatically determining, by the computing system, if one of the change operation or the resource is under strict change control;

automatically performing, by the computing system, a request-for-change (RFC) validation check on the change operation command if the change operation or the resource is under strict change control; and

automatically performing, by the computing system, a change operation corresponding to the change operation command to thereby change the configuration of the resource if results of the RFC validation check indicate that the change operation should be permitted, wherein the change operation command includes a RFC identifier for a RFC corresponding to the change operation command, and wherein automatically performing a RFC validation check comprises;

automatically performing a lookup operation in a service management system based on the RFC identifier to identify the RFC in a database of the service management system;

automatically determining if current conditions of resources of the data processing system meet requirements of the RFC, identified in the database by the RFC identifier, for performance of the change operation; and

automatically performing error processing on the change operation command if the RFC validation check on the change operation command fails, wherein the error processing comprises one of;

permitting the change operation to be performed and issuing at least one message to one or more data processing devices of the data processing system indicating the check failure and indicating that the change operation was permitted;

or

submitting an incident report, identifying a problem encountered, to a user and automatically performing a re-check of the RFC validation in response to the user responding with an input indicating the problem to be resolved.

2. The method of claim 1, wherein determining if current conditions meet requirements of the RFC for performance of the change operation comprises at least one of determining if a current date and time match a scheduled date and time associated with the RFC, or determining if a state of the data processing system is such that the resource may be modified by the change operation.

3. The method of claim 1, wherein automatically performing error processing on the change operation command comprises determining which error processing to perform based on the requested change operation and an identification of the resource.

4. The method of claim 1, wherein the error processing comprises:

utilizing an interface to a process manager of the data processing system to automatically open a new RFC for the change operation; and

sending a notification message to a data processing device of the data processing system indicating that the original change operation command could not be completed but that a new RFC was created for the change operation, wherein the notification message includes a new RFC identifier.

5. The method of claim 1, wherein automatically determining if one of the change operation or the resource is under strict change control comprises:

obtaining configuration information for the data processing system from a configuration management database (CMDB), wherein the configuration information specifies at least one of which change operations or resources are under strict change control; and

determining if one of the change operation or the resource is under strict change control based on the configuration information from the CMDB.

6. The method of claim 1, wherein the change operation is performed on a configuration item in a configuration management database, the configuration item representing the resource in the data processing system.

7. A computer program product comprising a non-transitory computer useable medium having a computer readable program, wherein the computer readable program, when executed on a computing device, causes the computing device to:

receive a change operation command specifying an operation for changing a configuration of a resource in a data processing system;

automatically determine if one of the change operation or the resource is under strict change control;

automatically perform a request-for-change (RFC) validation check on the change operation command if the change operation or the resource is under strict change control;

automatically perform a change operation corresponding to the change operation command to thereby change the configuration of the resource if results of the RFC validation check indicate that the change operation should be permitted, wherein the change operation command includes a RFC identifier for a RFC corresponding to the change operation command, and wherein automatically performing a RFC validation check comprises;

automatically performing a lookup operation in a service management system based on the RFC identifier to identify the RFC in a database of the service management system; and

automatically determining if current conditions of resources of the data processing system meet requirements of the RFC, identified in the database by the RFC identifier, for performance of the change operation; and

automatically perform error processing on the change operation command if the RFC validation check on the change operation command fails, wherein the error processing comprises one of;

permitting the change operation to be performed and issuing at least one message to one or more data processing devices of the data processing system indicating the check failure and indicating that the change operation was permitted;

or

submitting an incident report, identifying a problem encountered, to a user and automatically performing a re-check of the RFC validation in response to the user responding with an input indicating the problem to be resolved.

8. The computer program product of claim 7, wherein the computer readable program causes the computing device to determine if current conditions meet requirements of the RFC for performance of the change operation by at least one of determining if a current date and time match a scheduled date and time associated with the RFC, or determining if a state of the data processing system is such that the resource may be modified by the change operation.

9. The computer program product of claim 7, wherein the computer readable program causes the computing device to automatically perform error processing on the change operation command by determining which error processing to perform based on the requested change operation and an identification of the resource.

10. The computer program product of claim 7, wherein the error processing comprises:

utilizing an interface to a process manager of the data processing system to automatically open a new RFC for the change operation; and

sending a notification message to a data processing device of the data processing system indicating that the original change operation command could not be completed but that a new RFC was created for the change operation, wherein the notification message includes a new RFC identifier.

11. The computer program product of claim 7, wherein the computer readable program causes the computing device to automatically determine if one of the change operation or the resource is under strict change control by:

obtaining configuration information for the data processing system from a configuration management database (CMDB), wherein the configuration information specifies at least one of which change operations or resources are under strict change control; and

determining if one of the change operation or the resource is under strict change control based on the configuration information from the CMDB.

12. A system, comprising:

a processor; and

a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to;

receive a change operation command specifying an operation for changing a configuration of a resource in a data processing system;

automatically determine if one of the change operation or the resource is under strict change control;

automatically perform a request-for-change (RFC) validation check on the change operation command if the change operation or the resource is under strict change control;

automatically perform a change operation corresponding to the change operation command to thereby change the configuration of the resource if results of the RFC validation check indicate that the change operation should be permitted, wherein the change operation command includes a RFC identifier for a RFC corresponding to the change operation command, and wherein automatically performing a RFC validation check comprises;

automatically performing a lookup operation in a service management system based on the RFC identifier to identify the RFC in a database of the service management system; and

automatically determining if current conditions of resources of the data processing system meet requirements of the RFC, identified in the database by the RFC identifier, for performance of the change operation; and

automatically perform error processing on the change operation command if the RFC validation check on the change operation command fails, wherein the error processing comprises one of;

permitting the change operation to be performed and issuing at least one message to one or more data processing devices of the data processing system indicating the check failure and indicating that the change operation was permitted;

or

submitting an incident report, identifying a problem encountered, to a user and automatically performing a re-check of the RFC validation in response to the user responding with an input indicating the problem to be resolved.
