After disabling "wrap data types" on the datasource in Weblogic we had a pretty good performance win on processing big clob...

"Dutch : GroenLinks wil open source in ICT-opleidingen"

Op nu.nl is een artikel te lezen over GroenLink welke graag studenten en leerlingen met een ICT-opleiding al tijdens de studie kennis wil laten maken met open source software.
