Last weekend, I had the chance to attend the Linux Days Chemnitz. It’s an annual meeting of the German Linux family with roundabout 2,500 attendees and a FANTASTIC atmosphere. It was two days of hearing tech talks, enjoying rich nerd content and talkin’ shop. […]

New German Linux Forum (forum.linux-talk.de)
In the last weeks, some folks were busy to build a new German Linux Forum “forum.linux-talk.de”, since the predecessor was systematically ruined by the commercial owners. Especially Jean (wdp) and Hendrik (Nilpferd) invested much time and money into building the new environment. So the new forum is completely free of ads and commercials, and the […]
Oracle on Linux: How to hide your password when using a wrapper script

Oracle Clusterware root.sh issue: USM driver install actions failed (oracleoks.ko)
As I already said in my last post about “Can’t install ohasd service“, setting up Oracle Clusterware 11.2.0.4 on SuSE Linux Enterprise Server (SLES) SP2 should work flawlessly, but sometimes it does not. 🙂 This time, it was about the USM drivers.

Setting up Oracle Clusterware 11.2.0.4 on SuSE Linux Enterprise Server (SLES) SP2 should work flawlessly, but sometimes it does not. 🙂 It turned out that this would become a pair of blog entries. Second one is about “USM driver install actions failed (oracleoks.ko)“. But step by step. On Saturday morning, root.sh failed with the following […]
Oracle on AIX: How to find out the process memory usage
Calculating memory on Unix is tricky business. Especially when a complex software like Oracle Database has shared memory segments like SGA and Code Area. One might be convinced to use the following construction to calculate the overall memory footprint of Oracle processes running on this machine: ps -elf |egrep ” oracle* | ora_.*_* ” | […]
Speaking at COLLABORATE 14: “YOUR machine and MY database – a performing relationship!?”
I’m excited to announce that IOUG accepted my talk “YOUR machine and MY database – a performing relationship!?” for COLLABORATE 14 in Las Vegas. I’d love to see you there – for tech talk, gossip and meeting old and new friends! Abstract: Databases affect machines, machines affect databases. Optimizing one is pointless without knowing the […]
