Shutting Down Control-O

It is usually not necessary to shut down Control‑O. However, if shutting down Control‑O becomes necessary, it is recommended that the active Control‑O monitor be replaced by starting a new Control‑O monitor, as explained in Replacing an Active Control-O Monitor.

It is possible to shut down Control‑O with operator command F CONTROLO,STOP or P CONTROLO, but this is not recommended. Use an operator command to shut down Control‑O only if a problem cannot be resolved by the replacement method. If operator command F CONTROLO,STOP or P CONTROLO is used, Control‑O shuts down after a few seconds.

For CMEM users:

When Control‑O is shut down, the CMEM facility is also shut down. To restart Control‑O CMEM support after Control‑O has been completely shut down, issue the following operator command:

S CONTROLO,TYPE=CTOCMEM
