Description: System Logger has the following enhancements:
- Enhancements to the system logger component are intended to help
you avoid log stream primary storage full conditions that can lead
to performance degradation and outages. New function is designed to
enable you to specify that warning messages be issued based on thresholds
for log stream primary storage consumption above the HIGHOFFLOAD value.
- Multiple log stream offload/data set management tasking as well
as separation between coupling facility-based and DASD-only log streams
will reduce log stream primary (interim) storage full conditions stemming
from interference and delays between competing log stream offload
data set allocations and deletions.
This is intended to support
higher rates of log stream offload data set allocations, reduce primary
storage full conditions, and support higher overall concurrent log
stream offload rates. It will aid in overall concurrent log stream
offload throughput for log streams with large data bandwidths, such
as SMF, IMS™ CQS, and so forth.
- LOGR CDS (couple data set) log stream control info (Ocntl &
Pcntl) current for offloads provides a higher level of data reliability
and access by reducing potential data loss conditions.
When change was introduced: z/OS® V2R1.
