RE: Autobackup not found by RMAN

 Chris,

Good question, but the backup was current as of that day. I set maxdays = 2 so I wouldn't have to go through 7 days (default) worth of backups on tape....very slow.

By default, the initial format is %F for all devices, which combines the DBID, day, month, year, and sequence into a unique and repeatable generated name. This variable translates into c-IIIIIIIIII-YYYYMMDD-QQ, where:

• IIIIIIIIII stands for the DBID. The DBID is printed in decimal so that it can be easily associated with the target database.
• YYYYMMDD is a time stamp in the Gregorian calendar of the day the backup is generated
• QQ is the sequence in hexadecimal number that starts with 00 and has a maximum of 'FF' (256).

Any default format string specified with CONFIGURE must include the %F substitution variable.

%F is the only legal substitution variable for use in a control file autobackup format. Use of any other substitution variable is an error.

Regards,

Mark

Mark,

Not that I disagree with Jerome, but I notice that this time you left off "maxdays=2;".
Did that have anything to do with it too?...was your AUTOBACKUP > 2 days old?

Just curious,

PS What is the autobackup default? " '.../ora_cf%F'; " I think? I have run into trouble with this before, using non-default...but it was on backup (failure) if I remember?

 Hi Jerome,

Thanks for the information. About an hour after posting the original message I figured out what the problem was. It was exactly what you described. The solution in 10g is very simple you just have to set the autobackup format before restoring the spfile.

Run
{set controlfile autobackup format for device type sbt to 'cf_%F';  allocate channel ch01 device type tape;  restore spfile to pfile from autobackup; }

Thanks,

Mark

Hi Mark,

That's because you had overiden the default autobackup format in the persistent configuration ('cf_%F').

And now RMAN is asking the media manager to restore the spfile from pieces with the default format '%F' and none can be found. AFAIK you can't specify an alternate autobackup format upon restore (the instance is not mounted, you can not create a persistent configuration, at least with 9i). So in your case you may have to 'manually' specify the autobackup to restore by using "FROM 'media_handle'".
If you find a better solution please let us know.

Regards,
Jerome

OS: RH 3.5

I'm in the process of documenting our DR procedure. Our testing includes
recovering from disk and tape. So far recovering from disk has been
relatively painless. In contrast, recovering from tape has proven to be
less successful. Right now I can't get past the steps to restore the
spfile to pfile from autobackup. Has anyone run across this same problem
when restoring the spfile to pfile from autobackup from tape? Listed
below is the backup and restore commands.

Backup:

  CONFIGURE DEVICE TYPE sbt BACKUP TYPE TO BACKUPSET;
  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE sbt_tape TO
'cf_%F';
  CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;
  run {
        allocate channel t1 type 'SBT_TAPE' parms
'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so,ENV=(NB_ORA_SCHED=ORACLE
_DB,NB_ORA_CLIENT=jivrac1,NB_ORA_CLASS=OLS3_WIU_ORACLE)';
        allocate channel t2 type 'SBT_TAPE' parms
'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so,ENV=(NB_ORA_SCHED=ORACLE
_DB,NB_ORA_CLIENT=jivrac1,NB_ORA_CLASS=OLS3_WIU_ORACLE)';
        allocate channel t3 type 'SBT_TAPE' parms
'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so,ENV=(NB_ORA_SCHED=ORACLE
_DB,NB_ORA_CLIENT=jivrac1,NB_ORA_CLASS=OLS3_WIU_ORACLE)';
        allocate channel t4 type 'SBT_TAPE' parms
'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so,ENV=(NB_ORA_SCHED=ORACLE
_DB,NB_ORA_CLIENT=jivrac1,NB_ORA_CLASS=OLS3_WIU_ORACLE)';
        backup database PLUS ARCHIVELOG;
        release channel t1;
        release channel t2;
        release channel t3;
        release channel t4;
      }

Restore:

[oracle_at_wiuqjivrac01 dbs]$ export ORACLE_SID=WIUQD3
[oracle_at_wiuqjivrac01 dbs]$ rman nocatalog target /
