Purpose
Causes TDP to stop communicating with a CP.
While the command completes immediately, the CP does not stop until all activity on the CP ends. The status in a DISPLAY CP command indicates STOPPING until all sessions end, and STOPPED thereafter.
Syntax
where:
- cpname
- CP as IFPnnnn, where nnnn is the device number of the even-numbered CP device, in three or four hexadecimal digits.
Usage Notes
The purpose of the STOP IFP command is to stop a CP for servicing without shutting down the TDP to which it is attached. It can also be used if a CP is to be detached from the current TDP and then attached to another TDP. In this case, once the CP is stopped (logically detached from the current TDP), it must be physically detached from the current TDP using the DETACH CP command.
All activity on the CP must end before the CP stops. On some versions of the database, the CP stops when an active request completes. On other versions, all sessions on SPs associated with the CP must end before the CP will stop. In the latter case, in addition to application sessions, this includes any unassigned session pool sessions and any TDP internal sessions. It might be necessary to stop relevant session pools using the STOP POOL command and relevant TDP internal sessions using the DISABLE IRF command. The START POOL and ENABLE IRF commands can then be used to restore the necessary sessions.
Example: STOP IFP
STO IFP490
