OSS
•
Beginning with the G06.23 RVU, you can use SCF to configure an OSS process as
a persistent process under the persistence manager ($ZKRN). These SPRs (or
later) are required to support SCF:
°
T1084G06^AAJ
°
T1085G06^AAN
°
T6586G07^AAZ
°
T5800G06^AAR
°
T9082G02 ^ADA
°
T8624G10 ^AAN
°
T8397G00 ^AAB
For more information about the new attribute and considerations for its use, see
the SCF Reference Manual for the Kernel Subsystem.
•
Beginning with the G06.24 RVU, the OSS gtacl command has two more optional
flags added to its command line. For more information, see the T8628AAJ softdoc.
If you have to fall back to a previous RVU, scripts that contain one or more of these
optional flags must be revised because the function will not be available.
•
Beginning with the G06.27 RVU, the OSS environment has reimplemented its
process checkpointing and caching features to improve fault-tolerance for OSS
disk files. New fileset configuration options allow separate control of checkpointing
and caching and are implemented according to whether the standard O_SYNC flag
is used for an OSS file open. (The nonstandard S_NONSTOP flag is now ignored.)
The default configuration settings provide the recommended minimum level of fault
tolerance, but it is possible to configure a fileset for legacy fault-tolerant behavior.
Checkpointing and caching features are configured using OSS Monitor SCF
module command options, rather than the storage subsystem SCF DISK
command. (The new fault-tolerant behavior requires disk caching to remain
enabled by the storage subsystem.) For more information, see the Open System
Services Management and Operations Guide.
