2.14.2 Self-configuring NK-ISAM Pools in Data Spaces

*2 To further relieve the system address area, NK-ISAM files are *2 buffered in Data Spaces. At the same time, buffer areas are

*2 created strictly for individual files and no longer for file

*2 groups, thus reducing the number of lock conflicts over access

*2 to the buffer areas. The buffer areas are generated automatically *2 by the system; the user does not need access to programs or

*2 JCL in order to make use of the function. Previously an optimal *2 configuration of the ISAM pools was possible only through user- *2 defined ISAM pools, and required JCL access.

2.14.3 Performance improvements in BS2000/OSD V6.0B

*2 RSC for emulated disks

*2 On SX servers, IOs are run on emulated disks via RSC (Remote *2 System Call). This allows the IO CPU to be relieved and inputs *2 and outputs to be parallelized, resulting in a significant

*2 increase in capacity.

*2 Acceleration of the command COPY-FILE

*2 The doubling of the IO size from 32 kbyte to 64 kbyte reduces

*2 CPU usage and significantly shortens running time.

*2 Own SRPM Server task for Data Pubsets

*2 Previously both the Home Pubset and Data Pubsets were

*2 administered by an SRPM server task (RP01).

*2 From this version onwards, a new SRPM server task (RP02) is

*2 generated for the administration of Data Pubsets and the Home

*2 Pubset is administered exclusively by the RP01 task. Wait states *2 caused by Data Pubsets therefore no longer affect access to

*2 the Home Pubset.

2.14.4 New sub-system STATUS

*2 In the course of command expansions, the commands SHOW-JOB- *2 STATUS, SHOW-USER-STATUS, SHOW-SYSTEM-STATUS and STATUS (ISP *2 format) have been merged in the new sub-system STATUS. The *2 requirements for new software products or future BS2000

*2 versions can therefore be implemented faster and more easily.
