Disclosed is an apparatus, method, service product, and program product which each provide an enhanced, registration-based event handler mechanism. Listener programs are located and compiled before notification is needed. When notification is ultimately required, the pre-located listeners can be called directly without incurring the performance expense associated with first locating and then calling each listener.

A program product, apparatuses, and methods provide for the collection of profile information for a component of a software program by generating a data structure that maps at least one method to a component. The method includes a name, and the data structure maps the method to the component using at least a portion of the name of the method. A class or pattern may also be mapped to a component. Furthermore, during profiling, a statistic associated with the execution of the method is determined; the data structure is accessed using the name of the method to determine the associated component; and the determined statistic is associated with the determined component. By doing so, method level and class level information can be aggregated to improve profiling, often leading to a clearer picture of which components are contributing to the performance and memory footprint of large scale software programs.

A method, apparatus, and program product manage a plurality of resources of at least one logically partitioned computing system of the type that includes a plurality of logical partitions managed by a partition manager with an application level administrative console resident in a logical partition of the computing system. Each logical partition is allocated at least a portion of the plurality of resources. A user request to adjust the allocation of at least a portion of the resources using the administrative console is received. The resources of the logically partitioned computing system to adjust in order to satisfy the user request are determined using the application level administrative console. The application level administrative console accesses the partition manager through a resource allocation interface to adjust the determined resources of the logically partitioned computing system in order to satisfy the user request.

摘要:
A computer program communicates with a partition manager in the logical partition where the computer program is run. When resource allocation in the logical partition dynamically changes, the partition manager notifies the computer program of the configuration change. The computer program may autonomically adjust one or more configuration settings that affect performance of the computer program to dynamically tune the computer program to optimal performance each time the allocation of resources within the logical partition changes. The partition manager may notify the computer program of an impending change in resource allocation in the logical partition that runs the computer program, which allows the computer program to reconfigure its configuration setting(s) before the partition manager changes the resource allocation in the logical partition.
摘要:
An apparatus, program product and method associate a unique key with routines in an application to enable a profiler to ascertain whether to collect profile information for a routine during its execution. A key may be generated, for example, during deployment or installation of an application in an application server or other runtime environment, and subsequently associated with the routines in the application, e.g., by storing the key in the class and/or library files for the application. By doing so, each application in a runtime environment may be uniquely identified by a profiler during execution, such that profile information will only be collected for those applications for which profiling has been enabled.

A method, storage medium, and computer that, in an embodiment, receive a command that specifies a transaction identifier, keys, and partition identifiers. A primary partition is selected that executes on a first server. The first server comprises a first grid element that includes a first row that is identified by an initial key. An identification of the first grid element, the transaction identifier, an identifier of the primary partition, and the initial key are stored in a primary factory point at the first server. A secondary partition that executes on a second server is found. The second server comprises a second grid element that includes a second row that is identified by a second key. An identification of the second grid element, the transaction identifier, an identifier of the secondary partition, and the second key are stored in a secondary factory point at the second server.

摘要:
An apparatus, program product and method improve software updates processes within a logically partitioned environment by creating a new, proxy partition having substantially the same operating characteristics as an original partition, in addition to an updated software application. Network connectivity is transferred seamlessly over from the original partition to the new partition. While “hidden” from the network, the original partition continues to operate with reduced resources as the new partition takes over production operations. As such, the original partition remains in a ready state against the possibility of a problem arising with the new partition. In such an instance, network connectivity is transferred back over to the original partition, which resumes production operations as before.
