Disable an Existing Rule

Assume that you work in a secure government facility, and data security is a top priority. You do not care if security erase I/Os exceed their default threshold of 1 I/O per second, and would like to disable the rules that check for this.

To do this, first check in the source file of the factory rules (PSPA$EXAMPLES:PSPA$KB.VPR) and in the message text file (SYS$SYSTEM:PSPA$MSG.TXT) for the rules of interest. You find one rule, I0180, which focuses on security erasures. To eliminate this rule from further consideration in your knowledge base, add the following line to your rules source file MYRULES.VPR:

DISABLE I0180;

The semicolon terminator (;) is important: if you forget one of these, your auxiliary rules file probably does not compile.

To use this rule file, see the sections Build an Auxiliary Knowledge Base and Use an Auxiliary Knowledge Base for Reporting and Archiving.
