A customer of mine run out of memory due to much server processes of dedicated connected client sessions. As an alternative I tried to explain the options between DEDICATED and SHARED SERVER concepts as an initial attempt/workaround for the client software problems. Looking around on the internet for pictures and or newbie documentation, I found …

Vorig jaar heb ik behoorlijk wat vragen gekregen over of er een tool was, een methodiek, om BAG data van het Nederlandse Kadaster in een Oracle database te krijgen voor allerlei doeleinden. Basisregistraties Adressen en Gebouwen (BAG) data wordt onder andere uitgeleverd door het Kadaster in XML bestanden waarin alle Kadaster gegevens zijn vastgelegd. Deze …

Got a small question from Frits if I could help him make some XML data readable in one of the SYS.V_$CELL_% / V$CELL_% views. I have been a bit busy, in between jobs, to try to make some of those XML columns more readable anyway (for myself and others) so…lets have a go at it. …

Anton has a small but informative post on LOB handling across database links and avoiding a possible ORA-22992. I was not sure if XMLTYPE’s, CLOB based storage or Binary XML (Securefile) storage had the same limitations and/or in need of possible workarounds.

Since a long time, the database has had some versioning capabilities, long before features like “Edition Based Redefinition” in Oracle 11gR2 appeared. This versioning, via XMLDB functionality, is based on its XDB Repository access to the database. The XDB Repository is a file/folder metaphor that acts as a file server. You can enable this functionality …
