1.5 Installing the Prerequisite Software

The following software should be installed and configured prior to installing the TMA SNA software for UNIX:

1. If you are installing the CRM on Unix:
   1. Install a supported SNA stack on the operating system where the CRM will be installed. Validate the stack software installation, running any sample applications provided by the vendor.
   2. Configure the supported SNA stack.

   Refer to the Tuxedo Mainframe Adapter for SNA Release Notes for a list of supported SNA stacks.

   Note:

   Refer to the SNA stack vendor’s documentation on configuring your environment. A properly configured SNA protocol stack is required for the CRM to communicate with the mainframe application.
2. Install and configure the Tuxedo ATMI platform. Validate the software installation by running the sample applications, such as simpapp or bankapp.

   Refer to the corresponding product installation documentation for installation and configuration information. Some specific configuration tasks must be completed before you install TMA SNA.

3. Shut down all domain administrative and gateway servers within an application domain prior to installing TMA SNA software, particularly the following:
   • GWTDOMAIN
   • GWADM
   • DMADM

   Do not run the following commands until the installation is complete:

   • dmadmin
   • dmloadcf
   • dmunloadcf
