Users with DATAACCESS authority are exempt from the Row and Column Access Control rules.

Table data is protected against direct access to the table. Access using views is unrestricted.

In order to take advantage of this feature, applications must be changed to work with the RCAC feature.

Row and column level access control allows the creation of column masks that can control what column values a user is permitted to see.

In both DB2 pureScale and HADR environments data is available all the time.

DB2 pureScale transfers log files from a primary database to a standby database.

HADR persists data in the cluster caching facilities (CFs).

In a pureScale environment, the data is available all the time, while in a HADR environment the data is available most of the time.

DB2 LBAC allows you to use labels to reference database objects by a short name instead of the full qualified name.

DB2 LBAC lets you decide exactly who has write/read access to individual rows and columns by comparing the security labels between database objects and users.

DB2 LBAC monitors table data access and tables modifications made by database users.

DB2 LBAC is the DB2 authority in charge of issuing GRANT and REVOKE statements.
