Io.File and remote files

Question

Hi. I use the next code so I can get the files inside a Windows-shared folder. I allow write/read when I share the folder in my network. This is the code:
File root=new File("//HostName/sharedFolder");
FileFilter fileFilter = new FileFilter() {
public boolean accept(File file) {
return file.isDirectory();}
File[] files = root.listFiles(fileFilter);
then I get names from the files array... everyting goes well with a network computer without a access password, but when it has a password for log on, I get the name of the folder, but the listFiles throws a nullpointer... How can I get this work? any suggestion? thanks!!!!!!!!!

Answer 1

1. You can fine the trace in the udump folder ... you can check the file time stamp to check when you created the file as it may be possible that here are other user trace files too
$ sqlplus / as sysdba
SQL> alter database backup controlfile to trace;
Database altered.
SQL> show parameter USER_DUMP_DEST
NAME TYPE VALUE
user_dump_dest string /PROD/udump
SQL> exit
$ cd /PROD/udump
$ mv PROD_ora_30823.trc cr_ctl.sql
$ vi cr_ctl.sql
edit the control file script
Now you have a new control file script to re-create your control file.
2. You can edit the same and execute at nomount stage to generate new controlfiles ... remember controlfiles should be removed before creating the new ones
