Abstract:
A transfer of control to a batch application is intercepted, wherein a batch front-end routine receives control in place of the batch application and performs initialization processing. This initialization processing comprises issuing a DLI restart call and issuing a DLI checkpoint call. If the DLI restart call returns a checkpoint ID, then one or more databases associated with the batch application are repositioned. The transfer of control to the batch application is then resumed, whereby the batch application restarts from the checkpoint ID, if the checkpoint ID was returned by the DLI restart call, in a manner transparent to the batch application.
Abstract:
A Fiber Channel switch is presented that tracks the congestion status of destination ports in an XOFF mask at each input. A mapping is maintained between virtual channels on an ISL and the destination ports to allow changes in the XOFF mask to trigger a primitive to an upstream port that provides virtual channel flow control. The XOFF mask is also used to avoid sending frames to a congested port. Instead, these frames are stored on a single deferred queue and later processed in a manner designed to maintain frame ordering. A routing system is provided that applies multiple routing rules in parallel to perform line speed routing. The preferred switch fabric is cell based, with techniques used to manage path maintenance for variable length frames and to adapt to varying transmission rates in the system. Finally, the switch allows data and microprocessor communication to share the same crossbar network.
Abstract:
Apparatus for temporary containment of chemicals escaping from end members of a cylindrical container storing pressurized chemicals includes a plate, that can fit within the constricted walls of the ends of the cylinder and an inflatable tube around the edge of the plate. The tube, when inflated, will support the plate against the edges of the cylinder and contain the gas between the containment apparatus and the end members of the container. The repair device further includes a locking mechanism for positioning the plate with respect to threads of the cylinder and for preventing release of the plate in the event of deflation of the tube. A (CO.sub.2) pressurized gas capsule can be included to provide the pressure to expand the tubing. The plate can further include a valve for eventual release of the contained chemical at a convenient location.
Abstract:
A routing module applies a plurality of routing rules simultaneously to determine routing for a Fibre Channel frame. Each rule independently determines whether the rule applies to the frame as well as a routing result for the frame. The routing result includes a port address, a zoning indicator, and a priority designation that can be used to route the frame over a virtual channel in an interswitch link. A selector chooses between the results returned by the rules. A component receives routing results specifying an ISL group and selects a physical ISL for the frame. An in-band priority determined by the content of the frame header can also be used in place of the priority designation in the routing result.

Abstract:
An agricultural formulation of a virulent isolate of Beauveria bassiana, which has the characteristics of B. bassiana ATCC 74040, can be used to effectively control lepidopterous insects. This fungal strain has been found to be active against the egg stage of lepidopterans. Activity against the larval stages of lepidopterans is also shown.
Abstract:
A DLI call from the batch application is intercepted, wherein the DLI call is made for the purpose of accessing a hierarchical database. It is then determined if the access to the hierarchical database is a checkpoint trigger event. A segment counter for a trigger segment in a checkpoint trigger for the checkpoint trigger event is incremented if the trigger segment is identified by the DLI call. The segment counter is compared to a segment commit threshold in the checkpoint trigger and commit point processing is performed on behalf of the batch application if the segment counter is in a predetermined relation to the segment commit threshold.

Abstract:
An IMS batch application, originally coded to execute as a DLI/DBB batch application, executes on a computer system as either a Batch Message Processing batch application or as the DLI/DBB batch application. The transfer of control to the IMS batch application is intercepted, wherein the transfer of control includes a list of PCB pointers. It is then determined if the IMS batch application is being invoked as a Batch Message Processing batch application. If the invocation is for a Batch Message Processing batch application, a modified list of PCB pointers is formed from the list of PCB pointers. The transfer of control to the IMS batch application is completed wherein the completion of the transfer of control includes passing either the modified list of PCB pointers if the IMS batch application is invoked as a Batch Message Processing batch application, or passing the unmodified list of PCB pointers if said IMS batch application is invoked as a DLI/DBB batch application.
