To confirm a table is in sync and all data is consistent across the systems, Unity can validate the table from the Teradata core services or Ecosystem Manager. During the validation, Unity puts a read-lock on the source table to make sure the table does not change while being validated.
Use the following best practice to validate an individual unrecoverable table.
- In Unity UI, select OBJECTS.
- Select an object to validate.
- In the Validate object data window, select VALIDATE.
If the table is in sync, the validation request automatically activates the unrecoverable copy of the table.
