Session abstracts:

Buffer Pool Tuning – The Next Generation, will review the method and possibilities of Bufferpool and Group Bufferpool tuning that now exist in a modern world.

It will take the attendees through an explanation of what is a Bufferpool and the BP tuning process from gathering data to actioning recommendations and comparing results as well as showing how you can easily and simply manage all of these complex beasts using state-of-the-art rules and Zowe graphics to enable a truly modern experience.

Understand, manage and love certificates in z/OS and USS, will address distributed Db2 access. You can communicate with z/OS, USS, Db2, or any other server or service via “postcards”, or “sealed envelopes”. Even within a trusted network, unencrypted postcard communication isn’t state of the art and may compromise information you don’t intend to share.

Web-based solutions, like ZOWE, UMS, ADF,… require secure connections, but the setup can be frustrating. Setting up and using encrypted channels isn’t rocket science, but they’re all based on certificates that some people find difficult to manage.
This session sheds light on secure communication and their implementation in z/OS and USS services. I’ll explain how secure communication is set up, established and managed, as well as understanding difficulties that may arise.

Learn everything you need to know about TLS, SSL and the mechanisms of HTTPs, FTPs, sFTP, s/MIME, … communication. Understand different types of certificates and their repositories, like KEYSTOREs, TRUSTSTOREs and KEYRINGs. And, last but not least – who do you trust, who is trustworthy and why.
