backup databes problem

[Puskas Peter]

Hi,

I would like to backup derby databes. But I get this error:
Derby DB backup will be executed.
*The local depo is empty. Cannot create archive.
*
I call the backup like this :

            String query = CommonDbSqlStubs.backupDatabase;

            con = getConnection();

            stmt = new FsccPreparedStatement(con.prepareStatement("CALL 
SYSCS_UTIL.SYSCS_BACKUP_DATABASE_AND_ENABLE_LOG_ARCHIVE_MODE(?, ?)"));

            stmt.setString(1, tempDirectory);
            stmt.setInteger(2, 1);
            stmt.execUpdateAndCheck("database backup failed");
            con.commit();


or :

            String query = CommonDbSqlStubs.backupDatabase;

            con = getConnection();

            stmt = new FsccPreparedStatement(con.prepareStatement("CALL 
SYSCS_UTIL.SYSCS_BACKUP_DATABASE(?)"));

            stmt.setString(1, tempDirectory);
            stmt.execUpdateAndCheck("database backup failed");
            con.commit();

I could backuped database, but somthing happend and it is not working now.

I can not find the reason. If sombody know pleas let me know.


Thank you Peter
