Activating the IOA Archive Server (Control-V)

To activate the IOA Archive Server, issue the following command:

S IOASMON

The IOA Archive Server uses cross‑memory services to communicate with other address space requesting services. Like other address spaces using cross‑memory services, whenever the IOA Archive Server is shut down, the address space entry in the MVS Address Space Vector Table (ASVT) remains non‑reusable until the next IPL, and the message IEF352I is issued (in some MVS versions). If the IOA Archive Server 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, specify a large enough value in MVS initialization parameters MAXUSER, RSVSTRT and RSVNONR in member IEASYSXX in the SYS1.PARMLIB library. For information about these parameters, see the MVS Initialization and Tuning Reference Manual.
