Change NLS_NUMERIC_CHARACTERS On Existing DB

Howdy,

I was asked to do some data-mining on a DB which has it's decimal separator set as a comma.  This is mucking up many of my data-mining/statistical analysis programs in R, Perl, etc..   The users have no objections to me changing this setting globally, rather doing it on a per-session basis.  Can this be done, and how?  I was skimming Oracle docs, and they seemed to imply that you could only change it on a per-session basis or on database creation.

Prior to the introduction of the DBNEWID utility, you could manually create a copy of a database and give it a new database name (DBNAME) by re-creating the control file.

this paper will show you the process.

I solved this myself by adding wrapper code to all connection software to immediately do an ALTER SESSION after connecting.  Thanks, though.
