A debugging apparatus for debugging a particular application, session or transaction in a computer network environment. The environment includes a plurality of clients in processing communication with one another. The apparatus comprises identifying means for identifying a debugging mechanism to the computing environment, a debug table accessible to the debugging apparatus for storing any pertinent information relating to said debugging apparatus, identifying means for identifying at least one client present in the environment. The debug table stores any and all pertinent information about any identified clients as well as whether or not a particular application, session or transaction needs to be debugged. A determining means is also provided for determining if a particular application, session or transaction needs debugging so that debugging operation can be started accordingly.

Debugging client server programs from third party workstations

A computer program device and a computer program product are introduced comprising a computer storage debugging device readable by a digital processing apparatus; and a debugging program means is introduced. The debugging program means is to be used with the program storage device and includes instructions executable by the digital processing apparatus for performing method steps for debugging a particular transaction in a computer network environment, where the environment includes a plurality of clients in processing communication with one another. The method steps comprise: identifying at least one client present in said environment and storing pertinent information about any identified clients; providing information about whether or not a particular session needs to be debugged; and determining if a particular session needs debugging so that debugging operation can be started accordingly.

A method for debugging of a particular application, session or transaction in a computer network environment. The environment includes a plurality of clients in processing communication with one another. The method comprises of the steps of identifying a debugging mechanism to the computing environment, identifying any particular client and storing its pertinent information in a debugging table accessible by said debugging mechanism, and accessing said debug table at a later time when necessary to determine if a particular application, session or transaction running on a particular client needs to be debugged and recover the characteristic of the particular client.

Debuggin client server programs from third party workstations

An apparatus allowing a pair of interrelated C language operations, in particular a setjmp/longjmp and a signal/raise functions to be completed across a plurality of load modules. Upon the issuance of a first instruction or function, such as a setjmp, all information pertaining to the current running processing sub-environment that has been established by a first load module is saved in the memory in any location. Later, upon the issuance of a second and complementary instruction or function, such as a longjmp, issued from a different processing sub-environment established by a different load module, the computer's system stack is searched until the entry for the original processing environment is found. Then once it is established which initial environment the second instruction or function is related to, that information is retrieved from the previously stored memory location and the instruction or function is completed successfully.

Use of language instructions and functions across multiple processing
