Yes, I am sure. Just to make sure, I have compared the counts from export
log file and import log file. Also I compared it with import log file I did
in to 8i database.
What I did with two pass import is..first I have imported with constarints=n
then I imported with ROWS=N & CONSTARINTS=Y. So I am not doing any
truncates.
And to make sure again... I have tried troubleshooting one of the failed
constraints with smallest table:
Table TWESVS is having FK, FK_OF_VS_SYSID on column TWESVS.VS_OFF_SYSID
referring to TWESOF.OF_OFF_SYSID.
- The Error:
IMP-00003: ORACLE error 2298 encountered
ORA-02298: cannot validate (CMS.FK_OF_VS_SYSID) - parent keys not found
2) The constraint definition:
ALTER TABLE CMS.TWESVS ADD CONSTRAINT FK_OF_VS_SYSID
FOREIGN KEY (VS_OFF_SYSID)
REFERENCES CMS.TWESOF (OF_OFF_SYSID) ON DELETE CASCADE;
3) The user_constarints entry
SQL> select constraint_name, status from user_constraints
where constraint_name='FK_OF_VS_SYSID';
CONSTRAINT_NAME STATUS
------------------------------ --------
FK_OF_VS_SYSID ENABLED
4) And I tried disabling and then enabling manually, it gave ORA-02298
error.
Also I tried to catch the bad data into excetions.
The data in TWESVS.VS_OFF_SYSID ranges from values 1 to 107 (with some
values missing)
and the data in TWESOF.OF_OFF_SYSID ranges from 1 to 109.
And the following query returned no rows.
Please help me what could be the reason.
Thanks,
Surendra

Are your sure that the parent table data is getting imported fully? Number
of exported rows match
the number of imported rows?
During your subsequent import attempts, are you truncating the table?
