The Co:Z Co-Processing Toolkit is a collection of tools for connecting z/OS platforms to other computing environments securely and reliably. The toolkit facilitates:


z/OS Enabled SFTP View link z/OS Hybrid Batch View link z/OS Unix Batch Integration View link

Using Co:Z SFTP-server, systems with OpenSSH or another SFTP compatible client may transfer files directly to z/OS datasets, controlling all aspects of dataset allocation, formats, and codepage conversion.

Using Co:Z SFTP client, z/OS datasets and POSIX files can be transferred, interactively or from a z/OS batch job.


z/OS Hybrid Batch enables the relocation of traditional z/OS programs to servers running AIX, Linux, or Windows.

With the Co:Z Launcher and Co:Z Dataset Pipes components, any z/OS batch job can remotely launch a process on a distributed system, redirecting input and output from the remote process to traditional z/OS datasets or spool files.


An alternative to the IBM Utility, BPXBATCH, Co:Z Batch simplifies the integration of z/OS Unix command and shell scripts within batch jobs.

The Co:Z SFTP client and Co:Z Dataset Pipes can easily be integrated with Co:Z Batch.
