Will data pump preserve the order specified in the tables list ? [message #350600]

Hi,

I am trying import data to a target data base using data pump and those tables have some referential constraints defined and for which i am getting following error.

integrity constraint () violated - parent key not found.

Then i specified order(all parent tables first & then child tables), but data pump is taking its own order...

Will data pump preserve the order specified in the tables list ?

Could some one please help in this regard...

Thanks in advance..

Please read & follow Posting Guideline as stated in URL above

Try This...

1. Import with this parameter

CONTENT=METADATA_ONLY

2. Now Disable all constraints in your schema.

3. Again import with this parameter

CONTENT= DATA_ONLY, TABLE_EXISTS_ACTION = SKIP

4. Now Enable all constraints in your schema.

Hi Babu,

I want to import only data...

Apart from disabling & enabling constraints, is there is any other way that we can resolve this issue...

any options available in data pump to specify order of import...?

Regards,
puru

Try this.

1. Disable all constraints from your schema.

2. Import with this parameter

...CONTENT=DATA_ONLY , TABLE_EXISTS_ACTION = SKIP , EXCLUDE = CONSTRAINT , EXCLUDE=REF_CONSTRAINT

3. Now manually enable all constraints..

This should be work; But before try in development environment.

Thank you in advance.

Babu
