What Is Integrity checker?
The integrity checker is a database configuration utility that
you can use to assesses the health of the base layer data dictionary. The tool
compares the data dictionary with the underlying physical database schema. If
errors are detected, the tool produces error messages detailing how to resolve
the issues.
You run the integrity checker in the source environment
before and after you upgrade the database. Activities that might result in
errors include:
- Running
the upgrade process itself
- Running
the set of patch scripts included in updating a database
- Configuring
the database in the Database Configuration application
- Configuring
the database in the Migration Manager application
Errors reported by the integrity checker might affect migration. You
run the integrity checker in both the source and the target environments when
you run the Migration Manager.
You must ensure that the errors are corrected either by using the
integrity checker in repair mode or by applying changes directly to the
underlying database.
