ZIIP = NONE | EXTCOMP | SSLTLS | ALL | PROJECT
This parameter enables you to specify the setting for the zIIP Exploitation Feature. For more information, see zIIP Exploitation Feature.
| Subparameter | Description |
|---|---|
| NONE | The default. No CPU time is offloaded to a zIIP and IBM® Connect:Direct® continues to operate as it has for all versions. |
| EXTCOMP | Schedules SRBs to offload COPY step extended (ZLIB) compression and decompression CPU time to a zIIP. |
| SSLTLS | Schedule SRBs to offload COPY step SSL and TLS data encryption and decryption (not the handshake) CPU time to a zIIP. |
| ALL | Schedules SRBs to offload COPY step SSL and TLS data encryption and decryption (not the handshake) and extended (ZLIB) compression and decompression CPU time to a zIIP. |
| PROJECT | Same as ALL, except the SRBs are always dispatched
to a general purpose (CP) processor, not a zIIP processor. This allows
you to project C:D zIIP usage (rather than use the zIIP) when you
have a zIIP processor online. If no zIIP processor is online, there
is no difference between PROJECT and ALL. Note: The PROJECT setting
requires that you set the IEAOPTxx parameter, PROJECTCPU to YES. For
more information, see IEAOPTxx (OPT parameters) in MVS Initialization
and Tuning Reference (SA22-7592-21 or http://publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=/com.ibm.zos.r12.ieae200/ieaopt.htm)

Modifiable through MODIFY INITPARMS command: NO
