MAXPACK

This parameter specifies the maximum packing length in bytes when PACK=LENGTH parameter is specified.

2048 to 31744 (bytes): Specifies the maximum packing length (record packing buffer size) when the PACK=LENGTH parameter is specified.

Default: 2048 (bytes)

Notes:

The use of PACK=LENGTH and the target buffer size is recommended to improve file transfer performance.
In order to utilize zIIP processors for data compression, we recommend specifying a packing length of at least 4096.
