I typically start many logical screens when using ISPF. I reckon most system programmers also do so and tend to use the same set of logical screens for their sessions. So up to now we have to start each screen manually. ISPF allows a user to have up to 32 logical screens but there is no automation for creating these logical screens at ISPF startup.
Now with z/OS V2R1 ISPF allows you to define a set of logical screens that are automatically started when ISPF is invoked .
To enable this support you have to at z/OS V2R1. When you... [More]
The IBM z13, like its predecessors, is designed from the chip level up to support data processing. This includes a strong, fast I/O infrastructure, cache on the chip to bring data close to processing power, security and compression capabilities of the coprocessors and I/O features, and the 99.999% data availability design of the coupling technologies.
The figure below shows ten easy steps for implementing an I/O configuration for your z13. The numbered steps are described after the figure.

Integration and connectivity in a large enterprise are hefty concerns. Lack of either of these components can disable systems from 24x7 functionality – and affect your bottom line. Adding a level of complexity are the enterprise-wide applications and data stores that also require integration and connectivity. Application developers, architects, systems integrators, and systems programmers face these complexities daily.

Hopefully many of you are familiar with the z/OS Planned Outage Avoidance Redbook that we publised in 2006. The objective of that book was to create a concise source of information about the many enhancements to z/OS that help you avoid planned outages. That book was downloaded thousands of times and received very favorable star ratings.
That book covers the capabilities that were delivered up to and including z/OS 1.7. But our friends in Development have not been resting on their laurels - far from it. So, in... [More]

The TSO/E REXX external function call LISTDSI (list data set information) is used to retrieve information about a data set's attributes. z/OS V2R1 introduces some enhancements to the function.
Today I'll give you some updates on the following LISTDSI enhancements:
More information provided on multi-volume data sets
New multivol or nomultivol keyword
More information provided on muli-volume data sets
LISTDSI now provides information on all... [More]
There are times when you have no MCS consoles available and your only option is to use the HMC systems console. Unfortunately, the systems console is not very intuitive to use and doesn't present an interface similar to a traditional MCS console. z/OS Version 2 Release 1 comes to the rescue with support for the HMC integrated 3270 console, offering us a new type of MCS-like console called the HMCS. Let's take a look at this new HMCS console type.
The HMCS console is available during IPL and before and after SMCS... [More]
Automated synchronization of Resource Access Control Facility (RACF) data between systems can reduce the amount of time administrators spend manually keeping data synchronized between RACF databases. The RACF remote sharing facility (RRSF) can be used to synchronize RACF data between z/OS RACF databases but not between z/OS and z/VM RACF databases. Furthermore, RRSF is not available on z/VM to allow synchronization between z/VM RACF databases.
In our just published draft IBM Redpaper entitled, ... [More]
