Description
This parameter allows testing of server tables that span a 4-gigabyte boundary. For example, if SERV4G is X'FFFFF000', each ATB server will begin at XX_FFFFF000. If SERV4G is X'FFFF0000', each ATB server will begin at XX_FFFF0000. XX is determined by the storage available on the system.
The contents of the ATB server are specified by using the SERVGA parameter.
Example
If you want VTBL to span the 4G boundary, you can use these settings: SERV4G=X'FFFFF000', SERVGA=X'00040000', and LVTBL=200 (6400 bytes, X'1900'). This will force each server's VTBL to begin at XX_FFFFF000 and end at XX+1_00000900.
