Importing policies from XML

OpenEdge provides the persistent procedure, src/auditing/_imp-policies.p that provides an API to import an XML file containing audit policies into either a database or a ProDataSet. This procedure must be executed persistently and then the caller should execute the internal procedures depending on the target for the policies—a ProDataSet or a database. This procedure is used by both the Audit Policy Maintenance tool and the Data Administration tool when importing audit policies from an XML file.

For a database, call import-xml-db procedure and save-changes-to-db procedure. For a ProDataSet, call import-xml-fill-dset procedure and copy-changes-to-dset procedure. The cleanup internal procedure should be called before deleting the persistent procedure.

Note: Import procedure for loading audit policies from an XML file into an OpenEdge database does not refresh the database cache automatically. It's up to the caller to decide if the cache should be refreshed. You can either call refresh-db-cache procedure or directly call the AUDIT-POLICY:REFRESH-AUDIT-POLICY() method.

The following example is a combination of pseudo-code and ABL that shows how to use some of the procedures that are provided in _imp-policies.p and described in the sections that follow:

Example calls to the API for importing audit policies from XML
