IMS commands
You can use IMS™ commands to control IMS connections as well as to start and stop connections to DB2® and display activity on the connections.
Environment:You can issue an IMS command from an IMS terminal or you can invoke an IMS transaction or command by using the DB2-supplied stored procedures DSNAIMS or DSNAIMS2. DSNAIMS2 has the same functions as DSNAIMS but also provides multi-segment input support for IMS transactions.
| /CHANGE (IMS) | The IMS command /CHANGE resets an indoubt unit of recovery as identified by the OASN keyword of the /DISPLAY command. That command deletes the item from the standpoint of IMS, but it does not communicate to DB2. |
| /DISPLAY (IMS) | The IMS command /DISPLAY displays the status of the connection between IMS and an external subsystem (as well as all application programs communicating with the external subsystem), or the outstanding recovery units that are associated with the subsystem. |
| /SSR (IMS) | The IMS /SSR command allows the IMS operator to enter an external subsystem command. |
| /START (IMS) | The IMS /START command (with the SUBSYS parameter) makes the connection between IMS and the specified external subsystem available. Establishing the connection allows application programs to access resources managed by the external subsystem. |
| /STOP (IMS) | The IMS /STOP command (with the SUBSYS parameter) prevents application programs from accessing external subsystem resources. |
| /TRACE (IMS) | The IMS /TRACE command directs and controls the IMS capabilities for tracing internal IMS events. It also starts, stops, and defines the activity to be monitored by the IMS Monitor. |
