Debugging programs in a production environment

Programs in a production environment have any of the following characteristics:

  • The programs are compiled without hooks.
  • The programs are compiled with the optimization compiler option, usually the OPT compiler option.
  • The programs are compiled with COBOL compilers that support the SEPARATE suboption of the TEST compiler option.

This section helps you determine how much of z/OS Debugger's testing functions you want to continue using after you complete major testing of your application and move into the final tuning phase. Included are discussions of program size and performance considerations; the consequences of removing hooks, the statement table, and the symbol table; and using z/OS® Debugger on optimized programs.
