ORA-21560: while size is less than 1 GB for a CLOB variable

Question

Hi ,
I use "DBMS_XSLPROCESSOR.CLOB2FILE' to write data from a CLOB variable (Oracle 10g) to TXT file in unix. I assumed that
the clob can collect data of around 4 gb , but it is throwing the "Out of Range" error if the size exceeds
22502381 bytes, which is not at all sufficient to my requirement. I want to collect around 3GB in the variable.
Is it possible ? Please help

Well, ORA-21560 could indicate file opening issue. Check the file name 'V_DESC,TXT'. Most likely your UNIX either does not allow commas in file name or requires them to be escaped. And anyway, I believe it is a typo and you meant 'V_DESC.TXT'.
