Problems with import [message #244032]

Dear Forum,

I have serious problems. I'm a .net-developer and not an admin of oracle.
My boss gave me an external harddisk with some oracle-files and the order, to "copy this oracle files to a new computer". It is no chance to make a good backup because oracle is not running.

I tried with several methods and several OS to connect the DB-files with my oracle 10.0.1 (seems to be the version of my files, too) - but always I failed.
Connection is not possible.
It is soooo easy with mySQL and MSSQL - but with Oracle it seems to be an horror.

Can anybody help me? I heard, that maybe the problem is not solveable at all. This would be a catastrophy for me and my boss.

So: I'm hoping for help!

Greetings and X

The Wiesengrund

OS?
List Oracle/database files you have on your external disk.

Hi

thanks for the infos.

but a

imp username/password file=path.dmp log=path.log full=y buffer=10485667 commit=y grants=n

is simple, if you have a *.dmp file.

But I have no DMP-File. This is my problem.

A person in my office made a COPY OF THE DATBASE on an external harddisk.

He called this "backup".

Then the computer was stopped - and then it is broken. This man said "We have a backup, here it is" - and he does not understand, that he must export the files - and not copy the database.

And I must now rescue the Datas and transfer them to an other Database.

Know you understand my problem?

Greetings

Thanks, Mr. Cardot,

to make it more precise:

I have file-copy database backup (*.ctl, *.dbf, and .ora file) and
need to connect these files to working server.

I have oracle 10.2.0.1.0, .ora file has line "compatible=10.1.0.4.0"

I copy data files under oradata/NAME and
.ora file into dbs directory.

and next:

ORACLE_SID=PROPERSID;
export ORACLE_SID;
sqlplus /nolog
connect user/pass as sysdba
startup mount

and result:
ORA-27047 unable to read the header block of file
(on Windows I had ORA-27047 + OSD-04001 wrong block size)

So: whats wrong Sad

Can be

Wink

I have in the moment no idea, if the old version was linux or unix or windows.

But i can make, that they are the same. (maybe by trial and error...)

So it is important to know, if "same version" means: exactly the same. (if old version in Suse, if then Debian is possible)

But for first step lets assume: both are the same.

Thanks

Lets assume, they are the same. What's to do then?

If they were, it's unlikely you got "ORA-27047 unable to read the header block of file".
The steps depends on the environment, if you don't know or want to tell us what it is, You're On Your Own (YOYO).

Hi,

the problem is for me quite serious. So it is not a question, that I want not to give the information.
I'm searching, if it is possible - and how.
Then I must check, if i can do it - or if i need some support.
And then I must start to figure out, what OS we have, what oracle version and so on.

But this can take weeks -because I have to do it by trial and error Sad

Sad

pure horror.

So I'm glad about every good information!

Use an hexa decimal editor and post the first 256 bytes in hexa and alphanumeric formats ("od -x" "od -c" in Unix).
Put a list of files you have as I asked in my first post (attach it as txt file).

I can say you that these files come from a Big Endian platform (that is neither Windows nor Linux) with 8K block size.
It can't be restored on another platform type than the original one.
