Locking and unlocking roles
The System Security Officer can use alter role to lock or unlock a role manually.

Unlocking logins and roles at server start-up
Automatic login lockouts can cause a site to end up in a situation where all accounts capable of unlocking logins (System Administrators and System Security Officers) are locked. In these situations, use the -u flag with the dataserver utility to unlock a specific login or role when you start Adaptive Server.
For details on the syntax and rules for using the -u flag, see the Utility Guide.
