This section describes the prerequisites required to use an IBM System z Integrated Information Processor (zIIP) under Natural.
In addition to the Natural product license (product code NAT), zIIP support by Natural requires extra zIIP support licenses with the corresponding product codes (shown below in brackets) for the following environments:
Batch, TSO and Batch Servers (NAZBT)
CICS (NAZCI)
Com-plete (NAZCO)
IMS TM (NAZNI)
You can use the LIC option of the
ZIIP
(see the System Commands documentation) to display the
Natural for zIIP license installed.
To display the Natural product license you can use command SYSTP L of the Natural License Information function of the SYSTP utility (see the Utilities documentation).
All prerequisites for installation are described in Installing Natural for zIIP in the Installation for z/OS documentation.
The Natural Com-plete/SMARTS Interface or Natural CICS Interface version installed at your site must support Natural for zIIP and the prerequisites for installation mentioned earlier must be fulfilled.
The requirements and restrictions described in this section depend on the version of the Natural Com-plete/SMARTS Interface or Natural CICS Interface installed.
The requirements and restrictions that apply when using Natural for zIIP under Com-plete help optimize runtime performance and reduce the number of SRB/TCB switches to a minimum:
The Natural startup application must be cataloged with the Com-plete ULIB attribute PV (privileged) specified. For more information, see the appropriate Com-plete documentation.
If the Natural profile parameter
RELO is set to
ON, the number of Com-plete threads should match the number of
zIIP users to minimize the number of theads rolled in and out during a session.
For more information, see the description of the Com-plete startup parameter
THREAD-GROUPS in the Com-plete documentation.
