A performance improvement was recently made available to speed up processing for CARLa queries using z/OS UNIX file data. If you are using zSecure 2.1.0 or 2.1.1 it is recommended you look at the service provided through APAR OA46606 . If you work with systems with lots of catalogs and data sets, you might also experience benefits from changes made in that area. For zSecure 2.1.0 install the fix for APAR OA46616 . For zSecure 2.1.1 this change was largely incorporated into the base release. You can apply the fix for APAR OA46244... [More]
What screen size should you use? If your screen size is too small, there may be a lot of meaningful information off to the right or bottom of your screen. Personally, I find 62x160 is a good size for all enhanced 3270UI uses. If your monitor is too small to comfortably accommodate that size (and getting more difficult with every birthday!), then 43x80 is good for *most* enhanced 3270UI uses. If there are workspaces with many subpanels or many thousands of rows of data (such as historical summary displays), 62x160 might be better for... [More]

Starting from IBM Workload Scheduler for z/OS 9.1 the new object run cycle group can be defined to have more flexible run cylces and reduce the need of manually generated periods. It consists of a sets of several run cycles defined as database objects independent from applications. So a run cycle group can be used by more than one application and that an application can use a mix of its own run cycles and of one or more run cycle groups. It can be referenced in the application description with the possibility to specify the offset (positive and... [More]
What's new: The OMEGAMON Enhanced 3270 UI allows the definition of a Secondary HUB TEMS. If you wish to periodically monitor a HUB TEMS, in another data center for example, then defining a secondary HUB TEMS is one solution. Once a secondary HUB TEMS is defined switching between the primary and secondary HUB TEMS is easy using the switch command. The secondary HUB TEMS will also become the active HUB TEMS, if for example, the primary HUB... [More]

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). Background 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 on your favorite... [More]
