Blocking network loopback slows down firefox extremely

My newly installed Firefox web browser (versions 2 and 3, does not matter) was deadly slow. I don’t mean the display of web sites, no, I am talking about pulldown-menus or opening tabs. (For example, bookmarks folder opens within 6 long seconds.) Several hours I was not able to tell why it acts that way. […]

Grid Control startup fails, installUser=%s_userName%

Oracle seems to have an uncommon sense of humor. Executing gcstartup after patching the grid control server to 10.2.0.4 (Linux x86) fails with: /bin/su: user %s_userName% does not exist I am not surprised, since this is windows’ environment variable notation, and unknown to my Linux shells. Solution: In the head of /opt/oracle/grid/oms10g/install/unix/scripts/omsstup replace installUser=%s_userName% with  the username […]

Discovered openstreetmap for me

Hi, http://www.openstreetmap.org is a very cool project. Just discovered it for me, and spent the weekend with tracking and editing my hometown by car. Have a look here to see.

No action taken – including an upgrade to the most recent counterizeii version – did help, and after upgrading WP to 2.5.1 today the situation did not change. Now I asked […]

World’s fastest SATA drive: WD VelociRaptor WD3000GLFS

Hi, imagine a 2,5″ SATAII disk in a 3,5″ heat sink. It’s 300 GB in size, 120MB/s buffer-to-disk rate, 16 MB Cache, 10.000 RPM, consuming 6 Watts under load. Look here. I think this baby should take up to 150 IO/s, in combination with RAID 0+1 and a decent RAID controller or/and (Oracle’s) ASM this […]

Effectice load balancing for a (web?) service in RAC 10gR2

Hi, had to review service creation with DBMS_SERVICE package for a good-feeling load balancing in Oracle RAC 10gR2 several times – now I have to write it down for myself. 🙂 I needed it for a web service using shared server today, but the generic syntax is useful for all other purposes as well. Basic […]

Computer addicted? Parent’s training with Jörg Kabierske

Today (huh, it’s still “today”) I attended a so-called parent’s training (in German “Elterntraining”) at a local grammar school (Kepler Gymnasium Weiden). It’s topic was the handling of youths in contact with computers, internet and addiction risks. The lecturer was Jörg Kabierske, Regensburg (klicksalat.de). I was there just out of curiosity, to see what kind […]
