Limiting Row-level Security Authorization

A database administrator must establish row-level security on the system before users can begin assigning row-level security to their tables. Establishing row-level security involves two steps:

• Generating system administration tables
• Authorizing users to employ row-level security

Row-level security is managed through the three system tables:

• SRT—$SECURITY-RUNTIME-TABLE$
• OST—$OBJECT-SECURITY-NAME-TABLE$
• SXRF—$SRT-OST-CROSS-REFERENCE$
