Download the Co:Z z/OS self-extracting installer file (download available from dovetail.com).

Upload coz-vv.rr.mm.bin file to the z/OS HFS or zFS file system. Make sure you transfer the file with a binary mode transfer option.

Verify that the cksum command (cksum coz-vv.rr.mm.bin) results match the checksum values published on the website download page.

The installation script requires a small amount of temporary space to run successfully. Ensure that your /tmp file system is not full.

The installing userid should have READ access to the BPX.FILEATTR.APF SAF resource. If not, Co:Z will install without APF authorization on the ssh-socket-info utility, but will otherwise operate properly. See http://dovetail.com/docs/sftp/options.html#ssh_socket_info

Make the installer file executable:

$ chmod +x coz-vv.rr.mm.bin

Run the installer:

$ ./coz-vv.rr.mm.bin

*** Co:Z Installation complete  ****
(see README and LICENSE in install root directory for more information)
      

	Enter the name of a new or existing zFS or HFS directory that will become the top-level "home" directory for the Co:Z Toolkit installation. This directory must be in a filesystem that is writable by the installing user and contains 12MB of free space. If you supply the name of an existing directory that is not empty, you will be prompted to continue, as it is not generally advisable to overlay an existing installation with a new version.
	The fully-qualified name of the PDSE library to contain the Co:Z Launcher and Co:Z Batch program objects. If this dataset exists, it must be a PDSE and existing Co:Z load modules will be replaced.
	The fully-qualified name of the PDS library to contain sample JCL for the Co:Z Toolkit. If this dataset exists, if must be RECFM=FB,LRECL=80 and existing members with the same names will be replaced.
	Several Co:Z Toolkit Unix commands, such as cozsftp, fromdsn, todsn, etc. should be made available in user's PATH. One option is to customize /etc/profile to add <COZ_HOME>/bin to the PATH, but an alternative is to create symbolic links in an existing PATH directory to the Co:Z user commands in <COZ_HOME>/bin. To have the installation script create symbolic links, enter the name of the existing directory in which to create the links, or none to skip. When creating symlinks, this script will prompt you before replacing existing symlinks or files. The <COZ_HOME>/install/create-symlinks.sh script can be used to create these links at a later time, or to replace links to one Co:Z home directory (version) with links to another. See the comments in this script for more information and example usage.
	These messages will appear if the installing userid does not have READ access to the BPX.FILEATTR.APF SAF resource. Co:Z will install properly and can be used, but the SMF socket information is not guaranteed to be accurate.

Install and configure IBM Ported Tools for z/OS (SSH) per the IBM documentation.

If possible, configure z/OS ssh to use /dev/random. This can significantly decrease startup times for the z/OS ssh client. See the "Trouble Shooting" chapter in the IBM z/OS Ported Tools manual for more information.

Some of the toolkit components require additional configuration. Details can be found in the individual user's guides. See Chapter 1, Introduction for more information.
