The z/VSE guest operating system is supported.
Guest systems are generally designed to run in physical environments where IUCV is not supported. Therefore, they usually have no interface to IUCV.
To gain access to IUCV, a supervisor call routine (NETSVCD) and an IUCV support program (NETFLIH) are supplied with the IUCV line driver for the z/VSE guest operating system.
Note:
The routine NETSVCD is not the Adabas SVC and must be installed
under a different SVC number.
Because paging is required in z/VSE guest systems with 370 (VAE) and ESA mode supervisors, page-fixed buffers are required for the IUCV line driver.
Page-fixed buffers require the definition of real storage for the Entire Net-Work partition under z/VSE. The BUFFERS parameter is described in the section Entire Net-Work NODE Statement.
