RE: How can I get the BBED password?

If you believe that to be the case then perform the operation and dump = the redolog. If it is happening you will see the row migration in the = redo stream.=20

Thanks to all that have responded...

Well, something that I've noticed with regular dumps is that when you update a null column in a record, the whole row is migrated within the block to a new location and the space in never reused... I want to use bbed to see if that is true...

Thanks again to all,

Abraham

An excellent observation Tanel.
Abraham, what exactly are you looking to accomplish? The standard dump =
=3D

utilities of Oracle provide most of what you may be looking for. Out of
=3D

all the block repairs I have had to do over the years, the only thing =
=3D

bbed has provided me is the ability to run a verify on the block I have
=3D

repaired before I replace the block in the file, since dbv requires the
=3D

block to be a part of the file, otherwise I find the tool to be less =3D than useful.=3D20

In the world there are about 7 Oracle BDE/RDBMS development people who =
=3D

can edit blocks well and only 1 or 2 others who understand and try to =
=3D

edit the redo stream, and in my dealings with most of them they have =3D their own tools because bbed is archaic. The lower end Support personnel
=3D

who do use bbed, normally do not have the skills or knowledge to edit =
=3D

the blocks in the first place.

If you are trying to understand block structures, then you should read =
=3D

the documentation and the many papers that are available. There is no =
=3D

single source of information that will tell you everything and there are
=3D

a lot of flags and pointer values that are not documented anywhere but =
=3D

in the code itself. In the last year working on lots of block =3D corruptions from Linux induced problems, almost every time, the actual =
=3D

people who can edit blocks well, had to reference the code for =3D determination of some of the flags. It is just the reality that =3D everyone, can't know everything.
So back to the question, what are you truly trying to find out? The tool
=3D

has no training mode and it does not document the oracle block structure
=3D

for you.=3D20

Hi,

It's a really trivial task to find the password if you think about it a
=3D

bit,=3D20
that's why I think it's everyone's own responsibility to find it out if
=3D

you=3D20
actually need the utility. Also, the more people start messing up their=3D20
databases with bbed, the more likely will Oracle remove it from = next=3D20
distribution at all or encrypt the password or similar...

Tanel.
