A computer program product is provided. The computer program product includes a computer useable medium having a computer readable program. The computer readable program when executed on a computer causes the computer to generate a topology role in a topology role tier that is included in a topology pattern. Further, the computer readable program when executed on a computer causes the computer to create a component in a component tier that is defined in the topology pattern such that the component corresponds to the topology role. In addition, the computer readable program when executed on a computer causes the computer to map the topology role to a deployment target.

Method and system for topology modeling

A method of deploying enterprise applications or updates to data processing systems in a complex data processing environment. The enterprise applications or updates are phase deployed to the target data processing systems. Phased deployment includes the steps of preparing one affected node, quiescing all affected servers in the node, stopping all affected servers in the node, synchronizing the node, delivering the applications or updates, starting all affected servers, reactivating all affected servers, restoring the affected node, and repeating these steps for each affected node one at a time until all targeted data processing systems have been affected.

Increasing application availability during automated enterprise deployments

Algorithm for maximizing application availability during automated enterprise deployments

A method, apparatus, system, and signal-bearing medium that in an embodiment determine whether to log an exception based on whether the exception has already occurred. In an embodiment, exceptions that repeatedly occur at the same source and location within the source are logged on the first occurrence, and not logged thereafter. In this way, data can be saved about the exception, yet system resources are not consumed by repeated logging.

Logging of exception data

According to a preferred embodiment of the present invention, a managed object assembly (MOA) is used to abstract the business logic of a given system from the system's operational aspects or infrastructure-specific characteristics. The managed object includes a data object, a business object, a managed object, and a mixin object. By isolating the functions of the business logic from the infrastructure of the system (including database structure), a significant amount of flexibility can be obtained and system re-engineering becomes noticeably simpler. Specifically, by isolating the business logic from the system resource details, changes in the business logic can be made in a manner that is independent of any detailed knowledge of the resources accessed by the system. In addition, as the underlying infrastructure requirements and data structures are changed, only the data object portion and the mixin object portion of the MOA needs to be changed or updated to provide access to the newly modified data structures. This can create significant savings in time and money as a system is updated to provide additional capabilities.
