Transferring a dataset from z/OS to another z/OS system, but the zIIP processor is not being utilized for the transfer. The system has a zIIP processor and the XCOM parameters are set to take advantage of the zIIP processor. Why isn't the zIIP processor being utilized for this transfer?
The dataset being transferred has a RECFM=U and the data in that dataset is binary, so packing is not occurring. XCOM packing was designed to pack text or character data and not binary data.
Release : 12.0
Component : XCOM Data Transport for z/OS
Binary data may only use the zIIP processor if the individual records are > than 4096 bytes.
The requirements for the transfer to utilize the zIIP processor are:
1. The XCOM load library must be APF authorized
2. COMPRESS= must be set to anything other than NO
3. The buffer size must be > than 4096 bytes
