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.
