Hello.
This is pretty old but. Any ways. I think it will help some one who looks for the solution.
I think that ANALYZE TABLE XXX compute statistics will helps you.
Also, you shold try one of these:
- CREATE TABLE copy_of_main AS SELECT * FROM main_table - no errors
- Check if there is enough space on the device you are going to put .dmp file on.
- Changing the size of buffer parameter
- Using dbverify against datafiles that contain table data gives no errors.
- SELECT * FROM this table gives no errors.
ANALYZE TABLE works for me in almost every case.
Take care.
