If the IOA Online monitor has been installed and is already active, issue the following operator commands:

P IOAOMONx

S IOAOMONx

where x is the unique monitor ID.

Note: The IOA Online monitor uses cross‑memory services to communicate with other address spaces requesting services. Like other address spaces using cross‑memory services, whenever the IOA Online monitor is shut down, the address space entry in the MVS Address Space Vector Table (ASVT) remains nonreusable until the next IPL, and message IEF352I is issued (in some MVS releases). If the IOA Online monitor is brought up and down many times, the ASVT may become full. New address spaces do not start and an immediate IPL may be required.

To prevent this problem, set a large enough value in the MAXUSER, RSVSTRT and RSVNONR MVS initialization parameters in the IEASYSXX member in SYS1.PARMLIB.

For information about these parameters, see the MVS Initialization and Tuning Reference.
