Abstract

All unused memory is available to the transient area. When more storage is needed for other programs, the storage manager of the operating system signals the transient manager. The transient manager selects a block of storage to be removed from the transient area and releases storage to the storage manager. When a block of storage is no longer needed or other programs, the storage manager signals the transient permits more transients to be kept in processor storage and thereby increases the likelihood that a transient is reclaimed from processor storage and can be used without first being loaded from a secondary storage device.

Improved use of Transient Area in Nonpaging Data Processing System

All unused memory is available to the transient area. When more storage is needed for other programs, the storage manager of the operating system signals the transient manager. The transient manager selects a block of storage to be removed from the transient area and releases storage to the storage manager. When a block of storage is no longer needed or other programs, the storage manager signals the transient permits more transients to be kept in processor storage and thereby increases the likelihood that a transient is reclaimed from processor storage and can be used without first being loaded from a secondary storage device.

An operating system consists of a number of programs, some resident in processor storage and some, called transients, which are resident in secondary storage and are loaded into processor storage as they are needed. Conventionally, there is only one program in storage using the transient area of processor storage and the old transient program storage is deleted. Now, when a new transient is called, the storage is updated to contain the new transient program. The old transient is usually left in processor storage until its space is needed for another program. The transient manager keeps track of the transients that happen to be in processor storage, and a transient that is in processor storage can be accessed faster than one that must be fetched from secondary storage.
