Supplying a Guard File Title
You can specify guard file titles in either or both of the following ways:
-
As a database physical option

As a structure physical option
In an Enterprise Database Server database, you can attach a guard file to data sets, sets, and subsets.
Example 1
The following DASDL statement secures all data files in an Enterprise Database Server database with a guard file titled (DBA)SECURE/DATAFILES ON P:
DEFAULTS (SECURITYGUARD = (DBA)SECURE/DATAFILES ON P);
Example 2
The following DASDL statement secures the data set DEPARTMENT with a guard file titled (DBA)SECURE/DEPARTMENT/DATA/SET ON P:
DEPARTMENT STANDARD DATA SET (
NAME ALPHA(10);
ID-NUMBER NUMBER(4);
),
SECURITYGUARD = (DBA)SECURE/DEPARTMENT/DATA/SET ON P;Guard File Contents
