I did a validate cascade and there were no errors.    

  I did a dbverify on the index and data tablespaces no blocks corrupted.

  Paula,

Are you getting corrupt index/data errors? We had a similar situation and discovered that many of our corruption errors were caused by corrupt indexes. The indexes can be dropped and recreated to resolve this issue.

In some causes we had corrupt data; for those items I recreated as much info as I could from an index and found the rest of the data in a backup copy.

The verify process gave us some inconclusive results; some of the objects passed the verify yet reported block corruption which had to be repaired block by block.
