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.
Over the last few weeks I've had the pleasure of talking to many clients at IBM events, User Groups and 1-1 meetings about a range of topics affecting System z and the one that has provoked some of the most interesting debate has been the impact of Mobile. Nobody would dispute the fact that the increased use of mobile technology is having an impact on the Systems of Record that are critical to so many enterprises, but after talking to numerous clients over the last few weeks the question has come up over and over again: "Is this new...

On November 13, 2014 password security enhancements in RACF were made available for z/OS V1R12, V1R13, and V2R1. A service stream enhancement to zSecure 1.12, 1.13, 1.13.1, 2.1, and 2.1.1 was made available at the same time. Among other improvements, these updates allow a larger password space (additional special characters allowed) and a stronger encryption method (KDFAES).
Password security is a function as much of user education (e.g., do not use the same password on a strongly protected work account as... [More]
Important announcement to all System Automation for z/OS I/O operations (IOOps) users:
IBM System Automation for z/OS (SA z/OS) 3.5 is the last SA z/OS release, which includes I/O operations functionality.
If you use IOOps to manage connectivity in your active I/O configurations, IBM recommends that you use other established I/O configuration management solutions instead.
In order to keep IOOps functionality on an as-is-basis beyond the SA z/OS 3.5 release, you have to migrate to SA z/OS 3.5 some day. SA z/OS 3.5 includes an... [More]

The embedded data feature is introduced in the latest release of the OMEGAMON family of products. The new feature speeds up your problem determination efforts by making data from one product available in another's enhanced 3270UI workspaces. With embedded data, less time is spent switching between the OMEGAMON products. The accompanying playlists and videos demonstrate how to use the OMEGAMON enhanced 3270 user interface and embedded data to solve problems.
With this youtube playlist , you can play all of the videos or you can select... [More]
Recently, I worked with an airline company to identify why a few transactions out of hundreds per second were failing. Many z/OS applications act as a TCP/IP server and accept connections from users or applications on other hosts and mobile devices. The application at this customer that is experiencing problems does accept connections from end users, but it also acts as a TCP/IP client to retrieve information from servers running on Linux. Some of the transactions between the z/OS application and Linux servers were failing. Here's a brief... [More]
This is as easy as "one two three" now with OMEGAMON XE on zOS V5.3. First from the LPAR overview screen in the Enhanced 3270UI pick your LPAR with MSU use high - in this example it is Z2 at 98% of MSU Capacity - put "M" in the selection for the 4HR Rolling Average MSU Statistics for Z2.
The "M" shows us the MSU details for the LPAR Z2.
Pro-active automation using monitoring can
resolve performance problems before they cause outages
alert operators about monitor or automation exceptions
Many shops only automate IPL, messages, and shutdown.
Recovery is automated only for single resources without dependencies or with only basic parent/child dependencies
Recovery or moves have to be done by operators which leads to higher effort and recovery time, often exceeding the time allowed in Service Level Agreements.
With a high... [More]
In a recent blog, it’s been stated that IBM Tivoli Workload Scheduler for z/OS (TWSz) v9.2 version enhances operation efficiency with self-service catalogs and mobile connection (see here ).
Do you want to read about our clients’ opinions supporting this statement? In this post, I will report our clients’ quotes and will comment on some of the advantages that “mobilizing” Workload Automation provides.
"Mobile access is crucial for our organization to be competitive on the market. It accommodates... [More]
The new release of OMEGAMON XE for Messaging v7.3.0 has an Enhanced 3270 User Interface feature that allows you to issue any MQSC display or ping command directly from the command line in most MQ workspaces. You no longer have to switch out of the Enhanced 3270UI when you want to issue an MQSC display command just because you want to see the data in that familiar way. IBM MQ has about 45 display and ping commands, which provide a wealth of information about your queue manager and its objects.
For example, you want to see the... [More]

A system programmer received a call that one of the applications on a transaction server is having some problem. The system programmer logs on to a data analyzer, quickly glances at the analyzed reports, understands what might be going wrong and fixes it. This seems to be a first reaction when a customer notices an issue in their workshop.
There seems to be an exponential growth in the data generated worldwide. About 90% of data was generated in the last two years alone. It is also significant to know that 70% of the... [More]
zAware is a helpful tool from IBM's System Technology Group which can let you know when applications in your z/OS environment are doing unusual things. It monitors your system log for messages that are, for you, statistically unusual. zAware's browser session can show you when unusual message traffic is brewing by presenting what it calls it's "anomaly score". For you to know about it, though, you have to either logon to zAware's browser interface and keep your eyes peeled or better yet let OMEGAMON... [More]
