Welcome to the System z Management Blog, where you can read the perspectives from System z experts. This Blog provides insights into the System z solution, as well as technical details about specific IBM products.
In TWSz 9.1 several matching criteria have been added for defining in the Application Description how a dependency between predecessor and successor operations is resolved. The criterion chosen to pick a matching predecessor that best resolves the dependency can be that the matching predecessor is the one with: The nearest preceding input arrival time. This option was already available in previous versions. The nearest input arrival time within the same day of the successor. The closest input arrival time within a specified interval. The... [More]

Are your DB2 threads getting enough resources? Are the Work Load Manager Enclave (WLM) definitions too restrictive? If on the Enhanced 3270UI using the DB2 ® active threads summary (select 'T' from the Enterprise Summary) or the DB2 Thread Detail Accounting screen you see that the elapsed time for a distributed thread is greater than the threshold you have set (the plan name DISTSERV and the correlation ID starting with db2jcc_ indicates this is a distributed thread), ...

Many systems programmers spend hours debugging problems that involve looping or hung transactions. By working together, z/OS and CICS systems programmers resolve these problems much faster by combining the information available from OMEGAMON XE on z/OS and OMEGAMON XE for CICS on z/OS. A typical scenario is that the z/OS systems programmer identifies an address space with a high (or low) CPU Percent. Most often, this is in response to a situation alert or a reported problem. Starting with the Address Space Overview workspace in OMEGAMON XE on... [More]

This webcast will be held on March 27th, 2014 at 11:00 AM ET-US Overview : Are you being asked to support new technologies like mobile, big data and cloud? Do you have all the analytic information you need to monitor and support new workloads? Much of the data and workloads required for these technologies currently run on System z. Taking advantage of additional analytics can help support those workloads and more easily integrate System z into these new environments, while minimizing disruption of current enterprise workloads. We'll discuss... [More]

Welcome to the new age of CS&I OMEGAMON Beta programs! We have an exciting new program to offer you... As part of our use of agile development, each beta driver that we make available with the OMEGAMON Performance Management Suite beta will be a near GA-ready solution. This is quite different from the beta programs you have experienced in the past. You might recall that in the "old age" of beta programs, prior to agile development, you would get a beta driver of very early GA development code and quite... [More]
