A host library controller employs a plurality of ports for establishing a plurality of communication paths from the host library controller to a medium changer library. The host library controller further employs a processor and a memory storing instructions for the processor to issue a command from a medium changer command set, and to select one or more of the ports for communicating the medium changer command to the medium changer library depending on a command processing status of each port.

An apparatus, system, and method are disclosed for maintaining a context stack. A monitor module monitors a stack size after each monitor interval for a stack of a plurality of contexts. Each context defines communications between a process and a data set and comprises a pathway for communicating with the data set and a process identifier. A stack module deallocates a context that satisfies a stack policy from the stack if the stack size is within a buffer threshold of a maximum threshold.

Provided are a method, system, and computer program product for using gathered system activity statistics to determine when to schedule a procedure. Activity information is gathered in a computer readable storage medium indicating activity in a computer system during time slots for recurring time periods, wherein each time period includes a plurality of time slots. A high activity value is determined comprising an activity amount of a slot having a maximum amount of activity among the slots for the time periods and a low activity value is determined comprising an activity amount of a slot having a minimum amount of activity among the slots for the time periods. A threshold point is determined as a function of the high activity, the low activity, and a threshold percent comprising a percentage value. A determination is made as to whether there is at least one lull window having a plurality of consecutive time slots each having an activity value lower than the threshold point. A selection is made of one of the at least one lull window in response to determining that there is at least one lull window. The procedure in the computer system is scheduled to be performed during the time slots in the lull window in a future time period.

摘要:
A method to generate and save diagnostic data in the event of an application error, wherein the method supplies a first computing device comprising a microprocessor and a first computer readable medium and an application encoded in said computer readable medium, wherein said application comprises an error handling module. The method further supplies a second computing device comprising a microprocessor and a second computer readable medium and an error data management module encoded in said second computer readable medium, wherein said error data management module comprises a diagnostic data generating module, wherein said first computing device is in communication with said second computing device. The method executes the application, detects by the error handling module an application error, and detects by the error data management module the application error. The method then receives by the error handling module a completion signal from the error data management module, and provides an error signal from the error handling module to a support center.
