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.
NOTE: DSPOPT must specify 1 or 4 in order to use this 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.
