Verify the integrity of the data
Verify the integrity of your data, if you did not do this after you migrated.
To verify the integrity of your data, run the following commands:
oncheck -cI database_name
oncheck -cD database_name
oncheck -cr
oncheck -cc database_name
If the oncheck utility finds any problems, the utility prompts
you to respond to corrective action that it can perform. If you respond Yes
to
the suggested corrective action, run the oncheck command again
to make sure the problem has been fixed.
The oncheck utility cannot fix data that has become corrupt. If the oncheck utility is unable to fix a corruption problem, you might need to contact Technical Support before your proceed.
You will also need to verify the integrity of your data after you revert.
