The software required to use TermDSM is included with the MPE/iX

operating system. The MPE/iX operating system must be functioning

properly for TermDSM to work.

User Capabilities and Security Levels

The functions of TermDSM commands are restricted by three different

security levels. Each security level is associated with the capabilities

necessary to use commands of that level. The security levels correspond

to the Online Diagnostic Subsystem.

Table 3-1 lists the security levels and the corresponding capabilities.

When a user issues a command, TermDSM checks the user’s capability

list to verify that the user is authorized to use commands of that

security level. If the capabilities of the user are insufﬁcient, the

command is not executed and an error message is displayed on the

terminal.
