oracle 8i 恢复时不支持restore controlfile from ... and restore controlfile from autobackup; 也不支持set DBID= ， 在备份时也不支持CONFIGURE CONTROLFILE AUTOBACKUP ON;

在恢复控制文件时，建议在源数据库用
alter database backup controlfile to '$ORACLE_BASE/admin/orcl/bdump/orcl.ctl';(binary file), 然后拷贝到target的控制文件路径。

或用alter database backup controlfile to trace;(flat text file)。trace file is very usefu, u can re-create control file by it.
