Apparatus and method for interconnecting an application of a transparent services access facility to a remote source

Claim 1

A method of communication between a virtual machine in one collection of a transparent services access facilities and a resource of another collection comprising: connecting said collections through first and second VTAM interfaces; requesting in an application program contained in said virtual machine access to a resource manager contained in said another collection; decoding in a second virtual machine in said first collection containing said first virtual machine a request to connect to said resource; transforming said first virtual machine request into a VTAM ALLOCATE REQUEST, and a VTAM message; executing said VTAM ALLOCATE REQUEST through one of said interfaces to the remaining interface, whereby a session is established between said collections; transferring said VTAM message over said session to said second interface; transforming said transferred VTAM message to a virtual machine request; executing in a second virtual machine comprising said resource manager in said second collection said transformed request whereby said resource manager processes said original request.

Claim 2

A method of communication between a virtual machine in one collection of a transparent services access facilities and a resource of another collection comprising: connecting said collections through first and second VTAM interfaces; requesting in an application program contained in said virtual machine access to a resource manager contained in said another collection; decoding in a second virtual machine in said first collection containing said first virtual machine a request to connect to said resource; transforming said first virtual machine request into a VTAM ALLOCATE REQUEST, and a VTAM message; executing said VTAM ALLOCATE REQUEST through one of said interfaces to the remaining interface, whereby a session is established between said collections; transferring said VTAM message over said session to said second interface; transforming said transferred VTAM message to a virtual machine request; executing in a second virtual machine comprising said resource manager in said second collection said transformed request whereby said resource manager processes said original request.

Claim 5

An apparatus for communicating between an application and resource in first and second transparent services access collections comprising: a virtual machine in a first node of said first collection for supporting said application, said virtual machine issuing a request for service from said resource; a second virtual machine including a controller for servicing said request, and a gateway for converting said request into a VTAM connection request and a VTAM data frame; a first bidirectional interface for connecting said second virtual machine gateway to a VTAM network; bidirectional second interface connected to said network, and a second virtual machine in a node of said second collection, said second virtual machine including a gateway for converting a VTAM connection request and VTAM data frame to a VM data frame, said first and second virtual machines establishing a VTAM connection between said first and second interface; and, a resource manager connected to said second virtual machine for executing requests forwarded by said second virtual machine via said second VM data frame, and passing information from a related resource to said second virtual machine.

Claim 6

An apparatus for communicating between an application and resource in first and second transparent services access collections comprising: a virtual machine in a first node of said first collection for supporting said application, said virtual machine issuing a request for service from said resource; a second virtual machine including a controller for servicing said request, and a gateway for converting said request into a VTAM connection request and a VTAM data frame; a first bidirectional interface for connecting said second virtual machine gateway to a VTAM network; bidirectional second interface connected to said network, and a second virtual machine in a node of said second collection, said second virtual machine including a gateway for converting a VTAM connection request and VTAM data frame to a VM data frame, said first and second virtual machines establishing a VTAM connection between said first and second interface; and, a resource manager connected to said second virtual machine for executing requests forwarded by said second virtual machine via said second VM data frame, and passing information from a related resource to said second virtual machine.

Claim 9

An apparatus for communicating between a virtual machine application of a transparent services access collection and an external resource outside said collection comprising: (a) a second virtual machine within said collection, for servicing a request to connect to said external resource, said second virtual machine converting a VM request to connect from said first virtual machine to a VTAM ALLOCATE command and for completing an incoming VTAM ALLOCATE, said second virtual machine converting incoming VTAM data frames to virtual machine data frames, and outgoing virtual machine commands to VTAM data frames; and, (b) a bidirectional interface connected to said second virtual machine for connecting said outgoing VTAM ALLOCATE and VTAM outgoing data frame to a VTAM network, and for completing an incoming VTAM ALLOCATE with said second virtual machine to permit incoming VTAM data frames to be received by said second virtual machine.

Claim 10

An apparatus for communicating between a virtual machine application of a transparent services access collection and an external resource outside said collection comprising: (a) a second virtual machine within said collection, for servicing a request to connect to said external resource, said second virtual machine converting a VM request to connect from said first virtual machine to a VTAM ALLOCATE command and for completing an incoming VTAM ALLOCATE, said second virtual machine converting incoming VTAM data frames to virtual machine data frames, and outgoing virtual machine commands to VTAM data frames; and, (b) a bidirectional interface connected to said second virtual machine for connecting said outgoing VTAM ALLOCATE and VTAM outgoing data frame to a VTAM network, and for completing an incoming VTAM ALLOCATE with said second virtual machine to permit incoming VTAM data frames to be received by said second virtual machine.
