All, We have two applications that use one database, and the database is configured with character set WE8ISO8859P1. One of the applications needs to handle multiple languages so the vendor wants us to convert ot a 16 bit character set. However the other application in the database has not been tested against a 16bit database, and there are a lot of tables with fields defined as varchar2(4000) and clobs. Has anyone actually done such a conversion and is there anything we should be looking out for. P.S. Please do not suggest two databases as management have already said no. Thanks Fred. -- //www.freelists.org/webpage/oracle-l
