Fujitsu BS2OSD manual

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.
