HyperFabric Release Notes HP-UX 11i v1 and HP-UX 11i v2 April 2010

What Is In Version B.11.23.03.01

HyperFabric version B.11.23.03.01 supports the following feature:

• “Support for Large User Count” (page 7)

• “Additional Configuration Information” (page 7)

• “Documentation Availability” (page 7)

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 7) 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.

In the Non-Local Failover configuration mode, these values can be set to a maximum of (4997 *

Number of CLIC cards configured). Oracle RAC users must use the Local Failover configuration

mode.
