Sperren trotz fehlender Berechtigungen – Der seltsame Fall des blockierten Index-Rebuild

Ein Kunde machte mich kürzlich auf ein Blockade-Problem aufmerksam, welches er sich nicht erklären konnte. Nach einer kurzen Analyse ist das Szenario recht einfach beschreibbar:

Full day PreCon Practical Performance Analysis in Melbourne at Asia & Australia Tour 2018

As it has almost become a habit by now for me, I will be touring Asia this summer. This year not only Asia, but for the first time also Australia. (There, however, is winter, which sometimes leads to funny confusion in agreements until you get used to this.) 1st stop: Singapore – Azure SQL Database […]

Optimizing workflows with In-Memory and Natively Compiled Objects – or how it does not work

Conferences 2013: Frankfurt Database Days and a couple of “Oracle-Moments”
