Example—Decompress a File on the Remote Node During the

Copy Step

The “precomp=yes” parameter is used when the file was compressed by the

cdsacomp utility prior to this Process. The file is transferred by this Process as a

pre-compressed file. It is then decompressed by special processing as it is received

on the remote node.

sample process snode=cdunix1

step01 copy

(

file=/home/cd/upload/compressed.file

sysopts=”:precomp=yes:”

Example—Send Precompressed File to z/OS and Storing It as

Precompressed

The precompressed file is copied to the z/OS node with PNODE sysopts of

“datatype=binary”. The destination file is not decompressed. The DCB settings of

the original precompressed file are preserved on the z/OS node. The specified

checkpoint interval will be used during the file transfer. The file can be

decompressed with the z/OS cdsacomp utility.

sample process snode=cdunix1
