ORA-19870, ORA-19505, ORA-27041 on Windows 2008/2003

As I do most of mine Oracle DBA tasks on Linux, when such a person have to deal with Windows and the newest one (2008), some unexpected problems may arise. Even thought I may say that mine experience and understanding of RMAN are well, this topic will show that OS may brings DBA some of unexpected problems. As I was young DBA, I remember that in restore/duplicate procedure, backup location must remain the same as it was on target box. Problem may raise when on auxiliary box there is no such a disk (logical drive). In such a cases Linux has very adequate option with symbolic links (ln -s). On Windows there are generally two mapping drive techniques.
  1. subst
  2. net use
Regardless that Windows 2000 was able to deal properly with subst command, in later Windows versions this option was excluded and only option that remain was net use command. This is very well described in official Oracle document How to Configure RMAN to Write to Shared Drives on Windows NT/2000 (Doc ID 145843.1).

The configuration (environment)

In mine case I was dealing with RMAN online backup without catalog with disk as location. This was because I wanted "one time backup/restore"-just for that one cloning. So I wanted to use DUPLICATE RMAN command for cloning one database to different box.

To understand the problem here is a brief environment/configuration data:
Target database              Auxiliary database
Windows 2003 x64              Windows 2008 x64
ORION              ORION1
192.168.0.11              192.168.0.19
db_name: hcpro              db_name: hcpro
G:\rman_backup\hcpro              C:\oracle\rman_backup\hcpro*
* there was no G disk on auxiliary box!
RMAN configuration on target database.
RMAN> show all;

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'G:\rman_backup\hcpro\df%t_s%s_s%p';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:\ORANT\DATABASE\SNCFHCPRO.ORA';
Backup was done properly and without any problems to "G:\rman_backup\hcpro" location on target box. Here is list of backup files on target box:
G:\rman_backup\hcpro>dir g:
 Volume in drive G is Gis
 Volume Serial Number is B2CC-3FB3

G:\rman_backup\hcpro>
Notice that volume name of G drive is "Gis".

Then I copied all the backup files to auxiliary box in "c:\oracle\rman_backup\hcpro" directory. Because "G:\rman_backup\hcpro" was RMAN destination, on auxiliary box that directory should looks the same as it was on target box. So here is command that map G: drive on auxiliary box
net use g: \\ORION1\oracle /persistent:no
here is command from auxiliary box drive g that shows backup files:
G:\rman_backup\hcpro>dir g:
 Volume in drive G is OS

The solution I (network backup files)

Then I came back to early mentioned Metalink note and noticed something that was not too obvious at the first time (and certainly not in the early 2000 when I read this document carefully):
Special Windows 2003 Update :
As Windows 2003 has a changed access behavior compared to Windows 2000, the solution is a little restrict :
  • Don't use local drive letters for mapping network shares.
Workaround is to use UNC locations directly, e.g. backup to \\B\share
Since this is in fact an absolute location this is always the same for any node in the network.
So whether accessed from node A or node B, \\B\share is always the shared location on B.
So the same applies obviously to Windows 2008 as well, so change was not in Oracle but Windows itself. And here is what I did.

1. Add share on target box

On target box add share \\ORION\rman_backup in previously shown way on target box:
C:\>net view \\ORION
Shared resources at \\ORION

Share name    Type  Used as  Comment
rman_backup   Disk
The command completed successfully.

C:\>

2. Change RMAN parameter on target database

Change RMAN DEVICE DISK FORMAT parameter, which should point to UNC location (not disk path):
RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '\\ORION\rman_backup\hcpro\df%t_s%s_s%p';

old RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'G:\rman_backup\hcpro\df%t_s%s_s%p';
new RMAN configuration parameters:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '\\ORION\rman_backup\hcpro\df%t_s%s_s%p';
new RMAN configuration parameters are successfully stored
Check that new parameter is really active:
RMAN> show all;

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '\\ORION\rman_backup\hcpro\df%t_s%s_s%p';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:\ORANT\DATABASE\SNCFHCPRO.ORA';

3. Full backup

Perform full target database backup again. Important part (that really differ is how backup piece is presented (handle=\\ORION\RMAN_BACKUP\ parts):

The End

If you look in "Solution I" (that officially Oracle provides), I really think that few of DBAs do make RMAN backup to disk with UNC path in it's format.

In any case I find Linux more flexible and adoptive for such an tasks...and frankly to whole Oracle world. Unfortunately, today life set in front of DBA many OS's and in many cases-Windows as well.

Cheers!

    Damir,

    Thanks for your post. It helped me a lot! I do have a couple of questions, however. First, in step 6 you create a normal share on the auxiliary but I never see reference to it or use of it after that. I am not sure why. Second, with the absolute path specified to \\server\share my duplicate ran long as it appeared to restore from the target server. In previous duplicate commands on non-windows OS I would stage the backup pieces on the auxiliary server in directory names like that of the target. So all the restore/recover activity was taking place on the auxiliary. Any thoughts?

    Share was used for network copy files.

    "\\server\share my duplicate ran long as it appeared to restore from the target server"
    This is because in duplicate case it uses network resources and running directly from server (from dedicated partition) it is quicker but in that case you must have that parturition, what in some cases is not possible so "||server\share" is the only option.

    "Non windows" (i.e. Linux based OS's) has no limitation (as I said in topic) and all problem arises when Micro$oft change "net use" and "subst" statements. In this situation Oracle is not guilty for problems on MS environment ...

    Hope this clear up your thoughts.
