Mainframe, MVS and zOS Discussion

Besides OMEGAMON, MAINVIEW (from BMC) is another mainframe monitoring tool; MXI is another one. RMF and SMF data are usually important when talking about performance management and capacity planning for mainframes -- MXG and PACE are used to analyze SMF data for a site. There are a number of Redboo...

Yes, memory leaks happen to mainframes. However, you CANNOT take a snapshot at a point in time and state categorically that this mainframe has a memory leak. Memory leaks are found by checking memory usage over time; if the common memory usage keeps increasing over time then there may be a memory l...

Hi, I have some idea about the capacity planning and management in linux and unix. But now I have been asked to look for the mainframes also. One concept which I tried to explore is: memory leaks. Does memory leaks happen in mainframe too? And if they do, how do you recognize them? If you were given...

Hi, What are the Performance monitoring tools available in mainframes? It might be a vague question but I am thinking if all of them behave similar. I understand some what about Omegaon but then what are other tools we have. What should I learn to have a career in performance engineering? And also a...
