Migration
•
ALTER SERVER
•
STATUS SERVER
Several maximum values have been increased and the ability to control them has been
added:
•
The maximum number of inodes is now 2.2 million per fileset.
•
The maximum number of cached inode entries is now 500,000 per OSS name
server.
•
The maximum number of cached link entries is now 500,000 per OSS name
server.
Migration
Use of the new features is optional. No change in current site management procedures
is required.
Fallback
If a site alters a configuration value to use the higher inode or link entry caching limit
provided by this version of the product, fallback can cause the START FILESET
command to fail. Those limits must first be reduced so that the configuration in use is
compatible with prior released versions.
The fallback steps documented in the Open System Services Management and
Operations Guide or the softdocs for SPRs for the products T8621G11, T8622G11, and
T8623G11 should be followed. Fallback involves falling back to the prior released
versions for those products.
OSS Persistent Processes
The SCF interface for the Kernel subsystem has been enhanced to provide an
additional attribute for generic processes. This ASSOCPROC attribute allows
programs in the OSS file system to be configured and run as named generic
processes, with persistence monitored by the Kernel subsystem's persistence
manager process. Each ASSOCPROC program must be launched by a generic
process copy of the Guardian OSH command. For more information about the new
attribute and considerations for its use, see the SCF Reference Manual for the Kernel
Subsystem.
OSS persistent processes are supported on G06.23 and later RVUs.
Migration
Beginning with the G06.23 RVU, you can use SCF to configure an OSS process as a
persistent process under the persistence manager ($ZKRN). To configure OSS
persistent processes, you must have all of these SPRs installed:
