    Find DBID

      Dear all,

      I need to restore control files. During the process,
      RMAN> run
      2> {
      3> restore controlfile from autobackup;
      4> }
      Starting restore at 04-DEC-12
      allocated channel: ORA_DISK_1
      channel ORA_DISK_1: sid=541 devtype=DISK
      RMAN-00571: ===========================================================
      RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
      RMAN-00571: ===========================================================
      RMAN-03002: failure of restore command at 12/04/2012 15:12:24
      RMAN-06495: must explicitly specify DBID with SET DBID command
      Am unable to find DBID since the DB is in nomount stage. all the links and docs are referring to find DBID in mount stage. Please advise

          You can find it in you log file of RMAN backup which you have taken before.

          Hope you have taken RMAN bakcup.

              Refer to the RMAN backup log.
              The first few lines show the DBID

              eg is as below:

                          Have you checked this link it have many ways to get your DBID ,,.....May be somthing is helpful for you.

                          • 10. Re: Find DBID
                            Did you connect to catalog database ?

                            Or you are trying with connecting to target database. If yes, RMAN uses target database controlfile to read the information. Your database has to be in MOUNT mode.

                            In earlier post, it is connected to both target and catalog database.

                              Thanks all. I don't have a catalog database and DB is in nomount stage still
                              • 12. Re: Find DBID
                                OK, you've been told a couple of things:

                                1. Look at the log of the backup. You have a backup, right?

                                2. The link posted at least twice showed how to grep data files or backup pieces under some OS's. Could you let us know why that doesn't work for you?

                                Help us help you. Let us know what the real problem is.

                                  Do You have idea on where your controlfile autobackup is stored?

                                  rman target /

                                  SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/%F'; ------------>Assuming you have taken backup to /u01
                                  restore controlfile from autobackup;
