摘要:
A method to update code in an information storage and retrieval system comprising one or more processors, and existing code, where that existing code includes a Concurrent Code Load having (N) phases, where that Concurrent Code Load invokes an as yet unwritten Temporal Coupling File. The method provides a code update image comprising that Temporal Coupling File. If the (i)th phase of the Concurrent Code Load invokes the Temporal Coupling File, then the method reads instructions for that (i)th phase of the Concurrent Code Load from the Temporal Coupling File, and executes those instructions. The method completes each phase of the Concurrent Code Load, and then operates the system using the code update.

摘要:
A technique for updating elements in a data storage facility, including a single server or a multi-server system, such as by providing updated internal code packages to the elements. The update is performed using a fixed state machine, where the elements are updated in a coordinated manner within the constraints of the state machine. In a multi-server device, code packages are distributed to elements associated with the different servers in one traversal of the state machine, during distribute states of the state machine. The distributed code packages are activated in activate states of the state machine in multiple traversals of the state machine, so there is a serial activation. The code packages can be grouped in a flexible way by configuring an external update bundle used by the state machine. The distributing of the code is based on the grouping.

A self-curing single package zinc rich coating composition utilizing a novel copolymer binder composed of a mixture of alkyl silicate and alkyl titanate that cures upon exposure to atmospheric moisture in accordance with the equation:xSi(OR).sub.4 +yTi(OR').sub.4 +2(x+y) H.sub.2 O.fwdarw.(SiO.sub.2).sub.x (TiO.sub.2).sub.y +4xROH+4yR'OHwherein R and R' are alkyl groups selected from a group of alkyls consisting of ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl and 2-ethyl hexyl.Coating compositions utilizing the novel copolymer binder are formulated from a non-catalyzed silicate ester and an alkyl titanate ester having about 10% to 60% by weight titanate as TiO.sub.2 of the total weight of TiO.sub.2 and SiO.sub.2. The binder and coatings formulated therefrom allow the formulation of a single package zinc rich coating containing zinc dust which exhibits a good shelf life and may be formulated with additional fillers such as talc, clay and modified bentonite and solvent to provide a composition for coating ferrous metal which is durable and resistant to corrosion from salt water.
