New commands:
The percentage of main memory used for big pages can be changed
with the new command MODIFY-MEMORY-PARAMETERS. The command SHOW-
MEMORY-CONFIGURATION displays the current configuration of main
memory, including the use of big pages.
*1 The two new parameters/commands are only available on SX150
*1 servers. They are ignored on S systems and on SX100, SX130 and
*1 SX140 servers.
The command MODIFY-MEMORY-PARAMETERS is rejected with the message
EMM2350.
*2 - ISAM parameter set
*2 Discontinued parameter:
*2 The parameters GLBDFPS, DFPPROC, GLBDFPN are no longer evaluated
*2 as of BS2000/OSD-BC V6.0B due to the modified default mechanism
*2 for NK-ISAM-Pools
*2 New parameter:
*2 The new parameter MAXDSBN defines the maximum number of DATA
*2 SPACES that are generated for task-independent NK-ISAM-Pools.
*2 A range from 1 to 127 can be specified, the default value is 2.
System generation:
It is not necessary to generate the software for BS2000/OSD-BC
V6.0. The organization program SYSPRG.BS2.150 is part of the re-
lease unit BS2000-EXEC.
The utility program UGEN is no longer supplied.
The product IOGEN has been used for generating the I/O configura-
tion data since BS2000/OSD V5.0B.
As of IOGEN V15.0A, tape devices with DVC type CC (LTO-U2) can be
generated.
Note: If an IOCF with DVC type CC is used on a system with
BS2000/OSD V5.0B, the correction A0502425-001 is absolutely im-
perative.
System address space:
The limitation to system address space by the selected SYSSIZE
has been eliminated since BS2000/OSD-BC V5.0. The system also
uses less address space by moving internal tables into data
spaces.
