H06.25 Release Version Update Compendium

2 Operating System
OSS Resource Limits and Resource Agent Servers
The H06.25 RVU provides new OSS resources and increased file system limits. Features include:
• Increased usage of 64-bit addressable memory for internal OSS resources
• New OSS resources have been added (for example, an additional PXS area in 64-bit
addressable memory)
• OSS resources can be monitored via SCF, EMS events, and the Measure OSSCPU entity
• File open limits per processor for most OSS resources have been doubled. For details, see the
Environment Limits appendix in the Open System Services Management and Operations
Guide.
As of RVU H06.25, each processor in your system uses one $ZRAnn process that collects OSS
resource information. Each OSS resource agent process is automatically configured and started.
During the initial OSS Monitor start-up after updating to the H06.25 RVU, the Monitor adds a
record to the ZOSSSERV database file for each resource agent configured on the system (one per
processor).
For more information, see the OSS Resource Agent Servers section in the Open System Services
Management and Operations Guide.
Migration Considerations
In RVUs prior to H06.25, the OSS resources error and status EMS events were logged to only $0.
In the H06.25 RVU, these events are logged to both $0 and $ZLOG.
The H06.25 resource agents report EMS events for AF_UNIX buffers, PXS64, and INODES that
are not compatible with previous RVUs. HP recommends saving the current $0 and $ZLOG files
in case a fallback is necessary.
Fallback Considerations
A fallback to an RVU prior to H06.25 results in the older software encountering unrecognized
server-type records in the ZOSSSERV file. Upon encountering records with a server type value of
6 (ZOSS_VAL_TYP_RESOURCEAGENT), the prior RVU OSS Monitor treats these records as unknown
or possibly corrupt. The following symptoms would be observed:
• The SCF INFO and STATUS SERVER commands show #ZRA00–#ZRA15 as UNKNOWN
servers with no Params
• An attempt to START, STOP, or ALTER #ZRA00–#ZRA15 will fail with the diagnostic
"Configuration contains invalid data”
To correct these symptoms, members of the super group (255,X) users must issue SCF DELETE
SERVER commands for each “unknown” server after falling back.
After a fallback from H06.25, EMS events for AF_UNIX buffers, PXS64, and INODES will not be
properly formatted if the log is examined with the EMS template file of an older version.
Measure
As of RVU H06.25, Measure supports the following new features:
• A CID table limit of 1,024,000.
• Counters for the following OSS resources:
