The COMMIT tag commits changes to the information catalog database. When a COMMIT tag processes, the echo file is emptied before the next set of tags starts processing. This ensures that the echo file contains only tags that describe uncommitted changes.
If the Information Catalog Manager encounters an error, it rolls back the database to the last committed checkpoint. Insert COMMIT tags in your file to keep your data consistent, and to limit the number of changes that are canceled when the database is rolled back.
You can insert a COMMIT tag after any complete set of tags that define an action. Do not insert a COMMIT tag between the ACTION tag and the last tag that defines the data that is associated with the ACTION tag.
