Hi,

I am trying to use the datapump tool to migrate a 10g db to 11g. Everything works fine except for the "nameless" check constraints.

Am I doing something wrong or is there a fair explanation for it?

Thanks

How do they "work"? Any error? If so, which one?

Nope, no errors related to the constraints, they are not created. Other (named) constraints are created properly.

The export I use is a full export of the 10g db, no exclude parameters or other special options.

Read your post; do you see anything that shows us what is your error?

Copy and paste what you did and got.

Before, Please read OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code, use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version, with 4 decimals.

Regards
Michel

I don't know what you have.
I don't know what you do.
I don't know what you see.
It is really, Really, REALLY difficult to fix a problem that can not be seen.
use COPY & PASTE so we can see what you do & how Oracle responds.

As said:

I do a full export on the 10g database (RAC): expdp with no other special parameters except for the necessary files (output, log).
After that I do a normal import in a newly created 11g database (RAC): impdp with again no special parameters except for the necessary files (input, log).

The log file of the export contains no errors except for compilation errors on the packages because of missing grants to sys objects. But no errors reported about constraints, tables or other objects.

When I check the imported objects (through the view all_objects) I count 4000 constraints less then on the source db, all 4000 are nameless check constraints.

Please understand the following statement is true.
Different Oracle versions contain different objects.

You have a few alternatives available to you.
1) Ignore this observation & concentrate on actual problems & errors.
2) File a bug report with MOS
3) run in circles & scream & shout that the Sky is Falling.

You can ignore what we said.
We can ignore what you ask.
It is YOUR problem and we can live with it.
