Method of Adding, Changing, and Deleting Resources

This article describes a method for operating a computing apparatus to add, delete, and change resource definitions without shutting down the operating system. The method comprises the steps of: - maintaining two alternative libraries, the first being an active library storing resource definitions currently used by the

operating system, and the second being an inactive library; - preparing and storing in a staging library new resource definitions

describing transactions, programs, and data bases; - executing an online change copy utility to copy resource definitions

from the staging library into the inactive library; - executing a modify compare command to (a) determine differences in resource definitions

between the active and inactive libraries; and

(b) apply a QSTOP flag to

(1) all transaction, program, and data base

definitions which differ;

(2) all programs which access data bases

flagged with QSTOP; and

(3) all transactions which execute programs

flagged with QSTOP; - quiescing all transactions flagged with QSTOP; - upon quiescing all QSTOP flagged transactions, enabling the exchange of function of the alternative libraries,

such that the inactive library becomes the active library.

The described method may be implemented as an improvement to an information management system (IMS/VS) running under MVS on an IBM System/370, thus removing the requirement to stop IMS/VS to introduce changes to definitions, as follows:

(1) Define the new resource definitio...
