You should only run the SET DBID command in the following specialized circumstances:
- You are not connected to a recovery catalog and want to restore the control file (see Example 2-137). The same restriction applies when you use the Data Recovery Advisor to restore a control file autobackup. CONFIGURE can locate an autobackup and restore it only if SET DBID is issued before ADVISE FAILURE.
- You want to restore the server parameter file (see Example 2-138).
- You are connected to the recovery catalog but not the target database and use the FOR DB_UNIQUE_NAME option on the CONFIGURE, LIST, REPORT, SHOW, or UNREGISTER commands.
这个是官方文档的说法,但是我还是不明白为什么需要set dbid。
为什么知道了db_name还不能restore controlfile?为什么连到recovery catalog就不用set dbid? |
