Abstract
A method and system for managing information in a data processing system is provided. The data processing system includes one or more operating systems coupled to a coupling facility. Stored within the coupling facility is data, which is accessed by one or more users. The status of those users are also stored in the coupling facility. A number of operating system services are provided for recording the users' status and managing the data and the users of the data. The data may include cache, list and/or lock structures.
Claims75
A method for managing status information in a data processing system comprising at least one operating system, said method comprising the steps of:
- executing by said at least one operating system a user process, said at least one operating system being coupled to a coupling facility comprising processing means and a memory, said memory comprising a storage structure;
- and
- maintaining at said coupling facility status information indicating whether said user process is attached to said storage structure.
A system for managing status information in a data processing system comprising at least one operating system for executing a user process, said system comprising:
- a coupling facility coupled to said at least one operating system, said coupling facility comprising a processing means and a memory, said memory comprising a storage structure;
- and
- means for maintaining at said coupling facility status information indicating whether said user process is attached to said storage structure.
A computer system comprising:
- at least one operating system executing a user process;
- and
- a coupling facility coupled to said at least one operating system, said coupling facility comprising processing means and a storage structure, said storage structure comprising status information indicating whether said user process is attached to said storage structure.
