Dear,
In my work environment we have three groups of tools on Oracle 11g that includes (.NET, Oracle Forms6i(Desktop), Oracle APEX) so the nls_charaterset in database is "AR8MSWIN1256" and now we want to change to AL32UTF8. Moreover, I have some questions about that.
Is it possible to change it and what kind of migrate(export, Rman, ..) is suitable?
may be lost data after change NLS?
would be correct run those tools that I've mention it after change NLS?
Regards,
Saeed.
