When to Use

Use ALTER SINGLE to execute Single User jobs with external security or, after executing this option, to run in a MUF environment. If you use this option, Single User jobs run unsecured and all MUF jobs run secured.

Note: We strongly recommend that Single User jobs not be allowed to run against a Directory (CXX) that is externally secured. To ensure this, Security Administrators should allow no users access to the DTUTIL resource cxxname.DBUTLTY.CXXMAINT.ALTERSIN. If Single User is allowed to run against an externally secured Directory, table-level access for Single User is unsecured, that is to say, any Single User job can update any table with no security check.
