The IKE daemon can be stopped as follows:
STOP procname
If the IKE daemon was started from a cataloged procedure, procname is the member name of that procedure. If the IKE daemon was started from the z/OS® shell and the environment variable _BPX_JOBNAME was set, procname is the same as _BPX_JOBNAME. If the IKE daemon was started from the z/OS shell and _BPX_JOBNAME was not set, procname is useridX, where X is the sequence number set by the system. To determine the sequence number, from the SDSF LOG window on TSO, issue:
/d omvs,u=userid
This command shows the programs running under this user ID. For more information on _BPX_JOBNAME, see z/OS UNIX System Services Planning.
