Embodiments of the present invention provide methods, systems, and computer program products for building an environment. Embodiments of the present invention can be used to allocate resources and build an environment such that the environment is built when a user is prepared to test one or more portions of code in the environment. Embodiments of the present invention can be used to reduce the 'lag time' developers experience between waiting for the code to be built and for resources to be provisioned, and can also provide a less costly alternative to maintaining and operating dedicated environments.

Predictive approach to environment provisioning

In one aspect, a method for identifying software development teams causing operation incidents when changing and deploying code is provided. The method includes the steps of: collecting data regarding i) a number of deployed change requests for each of the software development teams and ii) a total number of incident reports; generating a time series for the number of deployed change requests for each of the software development teams and a time series for the total number of incident reports created; performing causality testing between the time series for the number of deployed change requests for each of the software development teams and the time series for the total number of incident reports created; and determining whether the total number of incident reports created can be expressed in terms of the number of deployed change requests for any of the software teams.

Identifying cause of incidents in the DevOps environment automatically

A computer system retrieves from data repositories change information indicating changes to entries. Each data repository is associated with a corresponding interface and at least two data repositories are associated with different interfaces, and at least one data repository lacks tracking of changes to entries stored therein. The change information retrieved from the data repository is stored within a storage unit. The stored information includes identification of each repository entry change without storage of the changed entry. Requests are processed to provide change information for entries within the data repositories, wherein processing the change information request for one of the entries includes retrieving from the storage unit the identification of the repository entry change for the one of the entries. Embodiments of the present invention further include a method and computer program product for tracking changes within data repositories in substantially the same manner described above.

Tracking changes to data within various data repositories

An authentication system and method for allowing an administrator to host a plurality of service principal names (SPNs) over a common network port of a backend server. The authentication system includes a client computer, a backend server, and a service principal name (SPN) apparatus. The client computer sends an authentication request to the backend server. The backend server performs an authentication procedure in response to a reception of the authentication request from the client computer. The SPN apparatus configures a plurality of service SPNs for the web service application over the common network port.

System and method for hosting multiple kerberos service principal names

A method and system in a data processing system for the efficient response to multiple different types of interrupts. The data processing system includes at least one host and a storage subsystem having storage subsystem devices and at least one storage subsystem controller. The storage subsystem controller operates in multiple different states. Interrupts of multiple different types are generated by sources of real time events and are received by the storage subsystem controller. A selected type of interrupt as a preferred next interrupt to be received by the storage subsystem controller is then determined in response to the determination of the current state of the storage subsystem controller. A particular state associated with the occurrence of the selected type of interrupt is then determined. Reversible processing associated with the particular state is initiated prior to receipt of a next interrupt wherein the selected type of interrupt is efficiently enhanced in priority in response to the current state of the storage subsystem controller.
