A plan including several groups of tasks is constructed for performing maintenance on a plurality of interrelated machines. A maintenance task in a first group is caused to execute within a window of time allocated for the maintenance. A determination is made that an estimated amount of time needed to execute a second group of tasks from the several groups is more than the remaining time in the window. In response to such a determination, the execution of the second group of tasks is omitted. The execution of a post-requisite task of the first group is completed. A maintenance task in the second group is executed during a second window of time allocated for the maintenance.

Managing maintenance operations in multi-machine configurations

Power usage is estimated in a computing environment by automatically detecting hardware configuration information by use of a software agent that is translated into power consumption information for implementing a plurality of power estimation models for efficient power consumption and utilization.

Estimating power usage in a computing environment

Apparatus for communicating with a server application. A first request is received by a first agent application on a first client computer system from the server application to request that a second agent application on a second client computer system communicate with the server application. Responsive to receiving the first request, a second request is sent by the first agent application to the second agent application on the second client computer system to communicate with the server application.

Client server communication system

Apparatus for communicating with agent applications. A first request is sent by a server application on a server computer system to a first agent application to communicate with the server application. The first agent application is located in a first network. If the first agent application fails to respond to the first request, a second request is sent by the server application to a second agent application to instruct the first agent application to communicate with the server application. The first agent application is located on a first client computer system that is in a zone with a second client computer system on which the second agent application is located.

An interface system is provided between a source component () and a destination component () having multiple parallel lines for transmitting data or parity bits (--) and one or more spare lines (-). An error detection means () identifies one or more faulty lines. A mapping means () re-routes data or parity from a faulty line to a spare line. A communication link () is provided for communicating the re-routing between the source component () and the destination component (). The error detection and mapping can be repeated to detect and re-route sequential multiple-bit line errors using additional spare lines (-).
