A small blog post silence but I did a lot; or not, I guess that would depend on your definition 😉 one and a half weeks ago, or is it already two, I was very busy with “fun” XMLDB stuff, that is, trying to figure out some peaces that are not in a manual.
Internals
I was trying to figure out some internals regarding XMLDB domain indexes, like the hierarchic index, nowadays referred to as the Path Index and the domain XMLIndex index. Going through a lot of $ORACLE_HOME\rdbms\admin scripts, I found out that those two very important XMLDB domain indexes (one dedicated for the XMLDB repository and one for XMLType Binary XML / CLOB storage support in 11g) are based on the ODCI, aka Oracle Data Cartridge Interface, aka the Oracle Extensible Architecture. When I have a better overview, insight into this matter, I will dedicate a post on this.
