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.

Discontinued parameter: 

  *2 

The parameters GLBDFPS, DFPPROC, GLBDFPN are no longer evaluated 

  *2

  *2 

for NK-ISAM-Pools

New parameter: 

  *2 

The new parameter MAXDSBN defines the maximum number of DATA 

  *2 

SPACES that are generated for task-independent NK-ISAM-Pools.

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.
