2011 promises to be another exciting year for z/VSE with z/VSE 4.3 just now becoming available, and some excellent  education events, and conferences. What follows should help you plan the year ahead.    

April 15 - 19, 2011—WAVV in Colorado Springs: WAVV 2011 will be held at the Crowne Plaza in Colorado Springs, CO. The agenda grid with session titles is available at www.wavv.org; as the abstracts are completed, they’ll also be posted. The session grid for WAVV 2011 contains some very enticing topics.    

May 2011—IBM System z Technical University in Vienna, Austria: The popular IBM System z Technical University featuring z/OS, z/VM, z/VSE and Linux on System z will be held in Vienna, Austria. For more information, visit www.ibm.com.  

September/October 2011—Planning for WAVV 2012: The WAVV planning sessions are now done via Web conferencing in September and October, so be sure a WAVV committee person knows ahead of time what session topics are important to you and is aware of your ideas to improve the WAVV experience. Visit www.wavv.org for contact information.

October 3 - 7, 2011—IBM System z Technical University in Miami: Technical experts from IBM will share their experience and expertise on z/OS, z/VM, z/VSE, and Linux on System z. For more information, visit www.ibm.com.

October 24 - 26, 2011—European GSE/IBM Technical University for z/VSE, z/VM, and Linux on System z in Berlin, Germany: Now in its fifth year, this event provides great information directly from the technical wizards that develop z/VSE, z/VM, and Linux.    

2011 Future Events and Live Virtual Class Schedules 

For z/VSE events that aren’t yet scheduled and up-to-date information on events, please visit  http://www-03.ibm.com/servers/eserver/zseries/zvse/events/.


A current schedule for Live Virtual Classes (LVC) will be maintained on the z/VSE Website at http://www-03.ibm.com/servers/eserver/zseries/zvse/education/#upcoming.

Topic selection and session scheduling are currently in the planning stage; if you have suggestions, please send them   to me or to IBM via the aforementioned link. 

News From z/VSE Development 

By the time you read this, z/VSE 4.3 will be available. Since its announcement and preview, more   functionality has been added, including:  Language environment enhancements for debugging, performance improvements, and a Language Environment/C TCP/IP socket API for easier configuration when multiple TCP/IP stacks are present VSE/POWER enhancements to direct punch output to the VSE Library, cancel jobs when an output exceeds a specified limit, and more Librarian enhancements to catalog OBJ-type members from SYSLNK The IPv6/VSE product, available since May 2011, will be updated and include a full function IPv4 TCP/IP stack with applications. Information is also available on z/VSE 4.3 changes to installation and run-time support for CICS/VSE 2.3.

VSAM Catalog Management API                                                                                                   

When internal VSE/VSAM functions need to access VSAM Catalog data, they use the        Catalog Application Programming Interface (CATLG API). Rather than accessing catalog records or control blocks directly, a parameter list is created, precisely defining the access that’s     needed. This parameter list is passed to the VSAM Catalog Management Phase, which returns the requested information.                                                                                                                    

User applications that need to access definition and status information about VSAM Clusters       defined to VSAM Catalog Management can utilize this API. To facilitate this access, VSE/VSAM developers have documented a subset of the CATLG Interface as a formal API and are distributing descriptive documentation, control block mapping, and sample programs. This was done specifically to assist customers with accessing VSAM Catalog data. More details are on the z/VSE home page; use the Documentation tab and reference section under VSE/VSAM.    

While at the z/VSE home page, select the Documentation tab and download the new entry under “System Hints and Tips from VSE Level 2 and Change Teams,” z/VSE Problem Determination Guide (PDG) dated October 13, 2010. The PDG contains some excellent information and examples on problem determination and how to use the debug tools.    

May 2011 be a happy, healthy, profitable year for all. Thanks for reading the column; see you all in the next issue.
