ASE 16 or ASE 15.7 – This is The Question…

For those considering to move up the ladders from their current ASE release (whether it is ASE 12.5.x or ASE 15.x) there are, obviously, two possible migration alternatives:  ASE 15.7 & ASE 16.   To make the decision more tricky, SAP has stamped both with the same supportability badge:  both have the same EOL dates somewhere […]

Transformables: From Warm Standby to Active-Active MSA with Zero Downtime…

How often in your career do you have a chance to dismantle the old architecture in its entirety and build it again – completely redesigned?  Usually, a company upgrades the hardware once in a three-four years cycle, while the “backbone” architecture outlives the hardware upgrades and lives dozens of year intact.

ASE 15.7: A Fight between Cheetah and Rhino…

It has been quite a long time since I have been able to write anything in this public space.   The reason is that I have been completely absorbed by one of the most exciting projects I have been managing for the last couple of years:   moving the largest ASE site in the country […]

ASE 15.7: Threaded Kernel vs. Process Kernel: Throughput Variance

I have just finished performing a controlled analysis of general performance differences for ASE 15.7 running process and threaded kernel mode on various platforms and hosts (RHEL running on Dell Xeon chips, Solaris running on SPARC M, SPARC T  and x64).  Although there are quite a few differences, the following image tells the story of […]
