Each load module goes through a simple automated process that instruments the binary, inserting InCert Agents, to perform the statement sequence tracing. The newly instrumented load modules are deployed in production in the exact manner as before. All previous attempts to perform such tracing capabilities have been implemented with source instrumentation or through service level interrupts. These techniques incur vast overhead and thus become impractical for production usage. This feature optionally eliminates the step of downloading load modules to the PC for instrumentation.
Results are available as part of the batch sysout and through an ISPF interface.
This feature optionally eliminates the step of downloading execution information to the PC for viewing of results. This tightly links the movement of source modules with the instrumentation process and automates it. The mainframe instrumentation program can be placed within a ChangeMan procedure and instrumentation will be made part of procedure execution. This tightly links the movement of source modules with the instrumentation process and automates it. Likewise, compiler listing processing also interfaces with ChangeMan stored compressed listings .
