1 HyperFabric Release Notes
The information in this document applies to the release of HyperFabric software product
(HyprFabrc-00) versions B.11.11.05.01, B.11.23.03.01 and B.11.23.04 on the HP-UX 11i v1
and HP-UX 11iv2 operating systems respectively.
Announcement
HyperFabric is a high-speed network link that runs on various HP systems running HP-UX.
HyperFabric supports Hyper Messaging Protocol (HMP) and the IP network protocol stack
(TCP/IP/UDP).
This release note contains information about versions B.11.11.05.01, B.11.23.03.01 and
B.11.23.04 of the HyperFabric software.
What is in this version
In HyperFabric version B.11.23.04, internally found defects are resolved.
Features supported in HyperFabric version B.11.23.03.01
HyperFabric version B.11.23.03.01 supports the following feature:
• “Support for large user count” (page 4)
• “Additional configuration information” (page 4)
• “Documentation availability” (page 5)
Support for large user count
Prior to the B.11.23.02 releases, each HP-UX instance limited the value of SKGXP attribute
CLIC_ATTR_APPL_MAX_PROCS. This value was less than 2500 in the Local Failover mode. This
limited the number of HMP instances created by Oracle to 2500 HMP instances, and indirectly
limited the number of Oracle end users.
With this release, the value of CLIC_ATTR_APPL_MAX_PROCS can be increased. To increase
and set the correct attribute value, sufficient number of cards must be present. And, these cards
must be configured as card-pairs. The maximum value of the attribute will be limited by the number
of card-pairs available. Refer section, “Additional configuration information” (page 4) of this
release notes to understand the same.
Additional configuration information
In the Local Failover mode, values of certain attributes depend on the number of CLIC card-pairs.
The maximum value that these attributes can take is 9994 multiplied by the (number of card-pairs
configured). These attributes are:
• CLIC_ATTR_APPL_MAX_NQS
• CLIC_ATTR_APPL_MAX_MEM_EPTS
• CLIC_ATTR_APPL_MAX_RECV_EPTS
The maximum value that theCLIC_ATTR_APPL_MAX_PROCS attribute can take is 4997 multiplied
by the (number of card-pairs configured).
For example, if there is a single card-pair (i.e., 2 CLIC adapters) present in a system, you can set
the following attributes to the given values:
• CLIC_ATTR_APPL_MAX_PROCS 4997
• CLIC_ATTR_APPL_MAX_NQS 9994
