What’s in This Version
What’s in This Version
HyperFabric version B.11.31.01 supports the following features:
Support for Transparent Local Failover on HMP
When a HyperFabric resource (adapter, cable, switch or switch port) fails in a cluster, HMP
transparently fails over traffic using other available resources. This is accomplished using
card pairs, each of which is a logical entity that comprises a pair of HF2 (HyperFabric2)
adapters on a HP 9000 node. HMP traffic can only fail over between adapters that belong to
the same card pair. Traffic does not fail over if both the adapters in a card-pair fail. Only
Oracle applications can make use of the Transparent Local Failover feature. However,
administrators do not need to configure HF2 adapters as card-pairs if TCP/UDP/IP is run over
HF2 or MPI uses HMP.
For more information, see the HyperFabric Administrator’s Guide (Part Number:
B6257-90055).
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’ 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 the CLIC_ATTR_APPL_MAX_PROCS attribute can take is 4997
multiplied by the (number of card-pairs configured).
