A user’s ability to execute commands in a green-screen environment is controlled by the limit capabilities (LMTCPB) parameter on their profile. Although without exit programs to extend IBM i security functions, even limited capability users could invoke commands through network interfaces such as FTP.

Does this sound familiar? You recently experienced an “unplanned outage” after an administrator inadvertently issued a PWRDWNSYS command while mentoring a new operator.

As more applications on IBM i become Java- or web-based, they’re less likely to send their important messages to a message queue. But don’t worry—Robot Console has that covered.
