4. Supported Debug Scenarios Submit and Debug Program in Batch Job –Job name is same name as program –Job owner is current User –Submitted to QUSRWRK subsystem Debug existing job on system –Browse option for locating job –Cut and paste job information STRDBG command from emulation session –Debug manager must be active and ready –Must be same user as registered in Debug Manager –Emulation session must be running on same ip address as Debug Manager –If criteria is not satisfied; traditional green screen debugger is launched

5. Advantages Run to Cursor Monitor/Watch several fields at a time Multiple Breakpoint Groups in 1 program Automatically Saves Previous Debug Session Save the current session to local drive

6. QTESDBGHUB Starting the Debug Hub –V5R1 Call QSYS/QTESSTRSVR –V5R2 STRTCPSVR *DBG Runs in QSYSWRK subsystem Single point of contact for user interface –Registered in TCP/IP service table (port 4026) –User interface uses port mapper to locate server Submits Debug Server jobs (QTESDBGSVR) Registration facility for iSeries Debug Manager –STRDBG command from an emulator will perform graphical debug instead of traditional green screen debug

7. QTESDBGSVR Submitted by QTESDBGHUB Runs in QUSRWRK subsystem –Make sure QUSRWRK subsystem is started –Make sure QUSRNOMAX job queue is not held Issues STRSRVJOB and STRDBG against job to be debugged One QTESSBGSVR job per user interface window
