A primary objective of IWQ is to provide improved performance for business-critical
interactive workloads by reducing contention that is created by other types of workloads. The
following types of z/OS workloads are identified and assigned to unique input queues:
򐂰 z/OS Sysplex Distributor traffic: Network traffic that is associated with a distributed virtual
Internet Protocol address (VIPA) is assigned to a unique input queue. This configuration
allows the Sysplex Distributor traffic to be immediately distributed to the target host.
򐂰
z/OS bulk data traffic: Network traffic that is dynamically associated with a streaming (bulk
data) TCP connection is assigned to a unique input queue. This configuration allows the
bulk data processing to be assigned the appropriate resources and isolated from critical
interactive workloads.
IWQ is exclusive to OSA-Express5S and OSA-Express4S CHPID types OSD and OSX, and
the z/OS operating system. This limitation applies to z13, z13s, zEC12, zBC12, z196, z114,
and System z10 servers. The minimum support requirements are listed in Table 7-47.

7.3.56 Inbound workload queuing for Enterprise Extender
IWQ for the OSA-Express features is enhanced to differentiate and separate inbound
Enterprise Extender traffic to a dedicated input queue.
IWQ for Enterprise Extender is exclusive to OSA-Express5S and OSA-Express4S, CHPID
types OSD and OSX, and the z/OS operating system. This limitation applies to z13, z13s,
zEC12, zBC12, z196, and z114 servers. The minimum support requirements are listed in
Table 7-48.

7.3.57 Querying and displaying an OSA configuration
OSA-Express3 introduced the capability for the operating system to query and directly display
the current OSA configuration information (similar to OSA/SF). z/OS uses this OSA capability
by introducing a TCP/IP operator command called
display OSAINFO
.
Using
display OSAINFO
allows the operator to monitor and verify the current OSA
configuration. Doing so helps improve the overall management, serviceability, and usability of
OSA-Express5S and OSA-Express4S.
The display OSAINFO command is exclusive to z/OS, and applies to CHPID types OSD, OSM,
and OSX.
