EXIGENCE
EXIGENCE Group Trace
The Group Trace is unique to EXIGENCE. It is an optional feature that overcomes a recognized limitation in the standard IBM GTF and C-Trace routines - the ability to capture a trace across the Sysplex.
Tracing the root cause of a network related problem in a complex environment could involve the capture and examination of multiple traces. For example, the problem of tracing a single client IP address with many connections on several systems is compounded in an environment where an IP client connects to a service running on multiple systems using dynamic VIPA. As IBM points out, in such an environment, it is impossible to be sure with which system the connection will be made.
The EXIGENCE Group Trace overcomes this problem. With a Group Trace it does not matter where the connection is made since the trace can be initiated on all systems simultaneously. From the Java Client, users simply define a VTAM or IP trace with all the same filtering capabilities of a 'standard EXIGENCE' trace. This trace will then be initiated simultaneously on the nominated group of systems. When a group trace is stopped, it stops on all the systems simultaneously and the trace results are then merged to give a single trace view as if the trace had been taken for a single connection on a single system.
How the Group Trace Works
Each individual trace which makes up the Group Trace may also be browsed in the usual way if required.
