The Workstation Agent assumes that you have already established one of these environments:

• A TCP/IP connection exists between your workstation and the host, and your workstation is running under one of these supported operating systems:
  • Microsoft Windows 2000/NT
  • AIX®
  • HP-UX
  • Solaris (SUN)
• An APPC connection exists between your Windows workstation and the host

All necessary APPC or TCP/IP communications software must be initialized fully before starting the WSA. The WSA does not attempt to initialize the communications protocol again after it receives the first initialization error.

For information about installation and customization of the APPC or TCP/IP software used on your workstation, consult the documentation supplied by your software vendor. Additional information can be found in Configuring communications for the ISPF Client/Server.

The WSA installation file is downloaded using the ISPF C/S Component Install Utility. This utility provides three ways of obtaining the file:

1. Using File Transfer Protocol (FTP): This option assumes that you have a TCP/IP connection (not APPC), that the TCP/IP on your workstation supports the File Transfer Protocol (FTP) and that FTP is operational at your workstation. An operational FTP requires that:
   • FTP be configured and started on the workstation.
   • The workstation FTP server (FTPD), or "Daemon," be active.
   • The users have the authority to transfer files. Users are authorized through entries in the FTP Daemon access protection file. See Configuration parameters for additional information.
2. Using an existing WSA connection to get a new or updated version: This option assumes that you have already downloaded and installed a previous version of the WSA and is suitable for use by those with TCP/IP or APPC connections.
3. Using a manual method: If your workstation does not support FTP, or you do not have an established connection, it is assumed that you have a means of transferring the ISPF C/S workstation programs down from the host files to the workstation. Although the ISPF C/S Install Utility does not provide an automated download procedure for all users, it does provide information that can assist in the download process.
