Abstract: In processing system that includes a processing element communicatively coupled to a storage system for storage of database files (35) managed by a database management system (34) having a transaction management facility (36), file access operations from application processes are intercepted and checked to determine if the operation is from a non-transactional process, and if so, whether an automatic transaction should be started for the operation.

Abstract: The reusable space launch system has a first stage vehicle or aerospacecraft, a second stage vehicle or reusable spacecraft and a third stage vehicle or reusable orbit transfercraft. All the stages have the basic aerodynamic vehicle elements of a fuselage, wings, and tail, with the incorporation of control surfaces to supply lift, stability and control. The aerospacecraft is configured to use ejector ramjet engines for powered flight and includes equipment to capture air to supplement oxidizer for the ejector ramjet engine during take-off and extreme high altitude In order to optimize aerospacecraft performance in a pull up movement to exit the sensible atmosphere, the aerospacecraft may include auxiliary ascent rocket engines. The aerospacecraft payload bay is accessed by nose load re-closable payload fairings. The reusable spacecraft is mounted on tracks on each lower side of the aerospacecraft payload bay.

Abstract: The orbital launch system is a three stage vehicle to launch orbital payloads. The system uses a turbofan powered aircraft as the first stage with an aerospacecraft attached by an underling aerospacecraft pylon at an aircraft engine mount for carriage. The aerospacecraft is the second stage and is powered by an ejector ramjet engine. The aerospacecraft has a cargo bay with cargo bay doors in its midsection. A booster rocket with payload is launched from the cargo bay by use of an ejection system. Normally the payload is mounted on a rocket booster to be placed in the proper orbit. The orbital launch system may also have a parachute drop recovery system to recover the booster rocket after it deorbits.
