IMS Version 9

IMS Command Language

Classic IMS commands can be entered from the master terminal. IMS classic commands are commands that are in the original IMS command syntax. Certain classic IMS commands can be entered from remote terminals, from the master terminal, or both. The criteria used for determining which commands can be entered from which terminals are established differently for statically defined terminals and for dynamically created terminals. IMS system definition and the Security Maintenance utility establish the criteria for statically defined terminals. RACF(R) or equivalent security product establishes the criteria for dynamically created terminals.

The standard terminal command defaults created by system definition can be modified by the Security Maintenance utility. Table 2 shows the terminal security defaults for IMS commands established by IMS system definition.

Optionally, commands can be entered from a TSO SPOC or the OM API. Both IMS classic commands and IMSplex commands can be entered from a TSO SPOC or the OM API. However, IMSplex commands can only be entered from an OM API, not a master or remote terminal. Some classic IMS commands are not supported by the OM API and some are not recoverable.

z/OS commands can be entered only at the z/OS system console and not from the IMS master terminal.
