Cheryl Watson’s Tuning Letter

Cheryl and I just finished taking part in the 2.5-day Nordic GSE 2016 conference in Reykjavik.  We really enjoyed the conference.  Everyone made us feel so welcome, and it was great to have a chance to finally meet people that have subscribed to the Tuning Letter for many years.  The organization was flawless, and they had dinners organized every night and tours this weekend for those that were able to stay for the weekend.  There were loads of excellent presentations, great support from many...

On May 13, 2016, IBM Flash10863 was updated to inform users that all internet delivery of z/OS product and service orders must use a secured download method by May 22. A summary of the flash was provided on May 5 by Marna Walle in her SHARE blog, “Are you electronic delivery secure?”.  Essentially, you can no longer use standard FTP for obtaining software, but must instead use FTPS, HTTPS, or “store and forward”.  The encrypted options have been available for years now, so hopefully you have...

In our Cheryl's List #190 (February 24), we sent a survey to our readers to determine how extensively some of the newer z/OS technologies were being accepted. The survey is still open if you'd like to take it or see the original questions - at www.surveymonkey.com/r/RJ57FBL. Thanks so much to the 220+ people who have already responded, the table below shows the results of the survey. This list is sorted in ascending order based on  'Currently using', so the least exploited features are listed...

We emailed Tuning Letter 2016 No. 1 to our subscribers on May 3.

Here's a Red Alert and some important dates that should be on your calendar: Immediately: zEDC Red Alert As our regular readers will know, Cheryl and I are big fans of zEDC (zEnterprise Data Compression). All of my experience with it has been positive, and all of the feedback we received from our customers has been positive. Sadly, however, we all know that no software is perfect, and zEDC is no exception. On March 14, 2016, IBM issued a Red Alert for a data loss problem with zEDC. The...

Readers of Cheryl Watson’s Tuning Letter will be familiar with Alain Maneville, from IBM France. Alain co-wrote an article about HiperDispatch for the Tuning Letter, and is also the author of the LPAR Design tool.  The LPAR Design tool allows you to enter your LPAR configuration and model the impact that changes in an LPAR’s weight or its number of engines will have on the CPC HiperDispatch topology.  We highly recommend the use of this tool if you want to optimize your HiperDispatch...
