What’s in This Version

HyperFabric version B.11.23.03.01 supports the following feature:

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).

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

• CLIC_ATTR_APPL_MAX_MEM_EPTS 9994

• CLIC_ATTR_APPL_MAX_RECV_EPTS 9994

System tunables for the shared memory should be modiﬁed based on the attribute values, but

shared memory must be less than 4 GB.
