Recovery Manager complete.


It was working 5 days ago and suddenly, it doesn't work...

Could it be a size problem, the 4 files are 1GB total  ???

If you have any clue, please let me know.
Thanks in advance.

Please ensure that your authorization code and the enabler code are error free and have not yet expired.

If there's no problem I'd suggest to have a look at Oracle8i Recovery Manager User's Guide and Reference -> if you haven't looked there already.

Please tell me when this didn't help!

Thanks for your answer. Yes I already read Metalink problem, documentations, but still don't know.
I have tested also the backup of one tablespace at a time on TSM to verify that I don't have any problem of datafile corruption but it did work properly.
Also, I have 2 more databases on the same system and the backup works properly for these ones. Their size is even bigger so it doesn't seem to be a size problem.
So why this one doesn't work anymore is weird...
I saw in the messages that something seems to be missing between the lines:

ORA-27028: skgfqcre: sbtbackup returned error
....... here should be an other message more significative on the problem as I saw on similar problems on Metalink.......
RMAN-10031: ORA-19624 occurred during call to DBMS_BACKUP_RESTORE.BACKUPPIECECREATE

The full export works fine too...

So I really don't know what is happening.. and I don't see what changed on this environment since it doesn't work...

As I'm not able to reproduce your error but regarding to your "file size idea" I've found out that there is a MAXPIECESIZE parameter that can be set -> even while this information is about 9i you can read and try to apply the information to your 8i settings:

In a chinese forum I've found something about "setting backup_tape_io_slaves = FALSE has been known to fix this problem" => but all explanation is in chinese which I don't know to read or speak.

If these hints lead to nothing then I'll be off of your question as I can't provide anything more productive. I'm sorry if I couldn't help!

Hi Raisor,
Thanks again for your help.  
That's an idea.  I already tried to downsize the backup by using the fileperset parameter (=1) and it didn't work with the first one, the USERS tablespace which is very small.
But I will try this MAXPIECESIZE on tuesday we never know and will give you feedback about it.
Have a good weekend.
Ralf KlattEmployee in Civil ServiceCommented:

I hope this will work => I've read that somebody has written an book about MAXPIECESIZE => I'll have a look if find what this is about => I'll get back on that book before tuesday! :)

Have a good weekend too ...

Best regards, Raisor

I could't find the information I was looking for -> what I've foud instead is:

From chapter 3: "Here is an example of controlling the size of a backup set piece or the entire backup itself. In this example, we are limiting channel 1 to create each individual
backup piece at a maximum size of 100MB."

This is interesting too -> Lots of error explanations and examples! (8.1.6):

Thanks for your help and researches.. I will have a look when I come back at work around Jan, 7th.
Sorry for the delay, I am on vacation and was on higher priority problems too weeks ago.
See you.

No problem!

... and a happy new year ;-))

Hi Raisor,

Finally I didn't do anything and it did fix by itself.. Don't ask me why, but that's a problem in todays environments. Too many technical people work on it at the same time (network guys, system admin, etc.) and nobody tells you if they really did something.
Well I am happy it works now, but not so happy for the mystery!!
Thanks again for your help and take care.
