UNLOCK Function—Unlock Online Terminal

Valid on z/OS, z/VSE, and z/VM.

Use the UNLOCK command function to unlock a terminal.

The UNLOCK command function:

• Is disabled if the NOLCFCHK attribute is attached to the ACID
• Cannot be routed through the security network with the CPF
• Prompts for the current sign-on password in z/VM, TSO, CICS, CA IDMS, and CA Roscoe

In TSO, the TSS UNLOCK command takes affect when going from one program to another. If you are in ISPF/EDIT, you can still ACCESS and ALLOCATE data sets to which you have access. The TSS LOCK/UNLOCK commands take affect when you leave EDIT/BROWSE.

An attempt to use a locked terminal:

• In z/VM, IMS, CA IDMS/UCF, and CA Roscoe, results in the immediate termination of the command or transaction. The only functions that can be performed from a locked terminal are unlock, signoff, WHOAMI, and other limited functions, such as TSO TIME, that do not access resources.
• In CICS and CA IDMS/DC, the ACID is prompted for his password. If the password is valid the request is executed, if not the request is terminated.

This command function has the following format:

TSS UNLOCK

For IMS only, this command function has the following format:

TSS(password) UNLOCK
