at first i run the following script as sysdba to maintain character set
-----------------------------------------------------------------------
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET INTERNAL_USE WE8ISO8859P1;
SHUTDOWN IMMEDIATE;
STARTUP;
----------------------------------------
then i connect ot my schema and import my database.
while backup using a Form it gives 'Internal Error Data Can Not Exported'. (Button code as below)
if i don't run the above script then no problem ,But i need do run the above script to maintain character set,what to do.

f varchar2(50);

out_file Text_IO.File_Type;
