How to enter IMS commands
These topics describe how to enter various types of IMS™ commands.
- IMS MFS 3270 master terminal format
You can use the IMS master terminal for messages, commands, and responses. - Using Multiple Console Support (MCS) consoles
You can enter IMS commands from Multiple Console Support (MCS) or Extended Multiple Console Support (E-MCS) consoles. - Outstanding reply numbers on z/OS consoles
Outstanding reply numbers are used only on z/OS® system consoles. They are used to pass input directly to IMS. Terminals defined to IMS do not use outstanding reply numbers. - Maximum length of command input from z/OS consoles
For single-segment commands that are entered from the z/OS console, the maximum character length (including command recognition characters) is 118. - Multisegment command input
Multisegment commands require an EOS (end-of-segment) indicator for all segments preceding the last segment, and an EOM (end-of-message) indicator for the last segment. - Commands in a DBCTL environment
In a DBCTL environment, there are no outstanding reply numbers for z/OS consoles, and therefore none should be entered. For a command, just enter the command recognition character (slash or other character preceding the verb) or IMS ID, followed by the command. DBCTL does not respond with the DFS996I outstanding reply number. - Commands from an LU 6.2 device
To enter a command from an LU 6.2 device, allocate a conversation using an IMS command verb as the TPNAME. - Qualifying network LU names and commands
Qualifying LU names gives the system administrator the liberty of using the same name for LUs on different systems by adding the network identifier. This eliminates the necessity to have unique names for every LU on every system in your complex. - Issuing commands to the OM API
You can issue commands to the OM API and receive responses from the API by using a single point of control (SPOC) application (such as the TSO SPOC, which is shipped with IMS) or the Control Center. - Batch SPOC format
The Batch SPOC is a utility program that uses OM services to submit IMS operator commands to an IMSplex. The utility program is not specific to DRD commands; it accepts any commands that are supported by the OM API.
