Description

Communications Server for Linux, V6.2 and V6.2.1 is an evolution of all the previous versions of the Communications Server family of products. For details about features and functions, visit

New functions

Linux 2.6 Kernel support: Communications Server for Linux (5724-I33) and Communications Server for Linux on zSeries® (5724-I34) now support server installations on the Linux 2.6 kernel distributions from Red Hat and SUSE. For Communications Server for Linux on an Intel system, the kernel must be a 32-bit Linux distribution. For installation on a POWER (OpenPower or POWER5) system, the kernel must be a 64-bit Linux distribution.

The Communications Server for Linux on zSeries can be installed on a 31-bit or 64-bit Linux kernel.

Linux on POWER: Communications Server for Linux has multiplatform support that now includes Linux on OpenPower and IBM eServer pSeries® servers.

Support for these POWER platforms requires either Red Hat or SUSE distributions.

AIX Remote API client: Communications Servers running in a domain of servers that support Remote API clients can now provide support for SNA applications running on AIX V5 platforms. When writing applications for the AIX platform, use the same description for compiling and linking found in the Communications Server for AIX. Visit

The connection between the AIX client and the Linux servers is over TCP/IP. Any SNA application on AIX that uses the CPI-C, APPC, LUA, and some NOF interfaces for the Communications Server for AIX V5, and later, can use this AIX Remote API client. Interfaces for the previous version, Communications Server for AIX V4.2, are not supported by the Remote API client.

Primary LU support: LUA applications usually connect to host mainframes as secondary LUs. This means that the definition for the sessions is controlled by the host application, which sends the BIND to start a session. Communications Server for Linux can now act as a primary LU to downstream SNA-dependent devices over LAN interfaces using the RUI_INIT_PRIMARY interface. Using this interface, an application can connect downstream dependent LU sessions without the need for a host mainframe.

To use primary LU applications, the node must be configured with downstream LU (or a downstream PU template) that has a host LU name of #PRIRUI#. This indicates to the server that the applications using RUI_INIT_PRIMARY control these PUs and the LU resources assigned to them. The PUs can be used only on LAN ports.

Remote API client updates

The following updates are included.

Name change: Communications Server for Linux Client is now called Remote API client.

Linux and AIX client installation: When installing the Communications Server client or server on a system that already has a previous version of the code installed, you must uninstall the server or the client first. Configuration files are not deleted or modified by this process.

Windows clients: When installing the Communications Server client on a system that already has a previous version of the code installed, you must take the following steps to retain your current configuration:

  • Stop the Communications Server client service by issuing the net stop sxclient command.
  • Close the Windows client monitor icon.
  • Install the product without removing the previous version.

If you remove the existing Windows client, the configuration information is deleted from the Windows registry database. You must enter the configuration again after the later version is installed.

The Remote API Client for Windows now includes a diagnostic tool for service. This tool creates a compact file that is self-extracting. The problem determination file contains:

  • Relevant registry contents
  • Directory contents of everything in and below the install directory
  • File version information of all installed binaries
  • Locations of all log and trace files
  • Output from commands

The tool copies all log and trace files into snapd. When directed to gather the problem determination information, you should send a snapd.exe file to the Communications Server for Linux service organization. This information can help provide service for reported problems.

Documentation updates

The following documentation has been updated:

  • LUA Programmer's Guide
  • Administration Guide
  • NOF Programmer's Guide

IBM Communications      IBM Communications   Communications
 Server for Linux        Server               Server

The Communications Server for Linux has one charge unit — per concurrent user.

A user is defined as a person. A concurrent user is any user that accesses and uses the program at any given time. You must acquire a user authorization for every concurrent user that will directly or indirectly access and use the program. Under this license, you may allow multiple concurrent users, up to the number of user authorizations acquired, to access and use the program either directly or indirectly (such as by accessing the program via an intermediate machine or piece of software).

As an example, if a multiplexing program or application server (that is, Transaction Server, DB2®) connects to the program providing access on behalf of multiple concurrent users, then one authorization for each of these multiple concurrent users is required.

In addition, for application programs that are not associated with actual users, but still use Communications Server services such as TN3270, SNA (APPN®, DLUR), and Enterprise Extender, a user authorization is required for each active upstream or downstream connection established to the Communications Server. In an APPN environment, a connection is an active link to an adjacent nodes.

The license to the program includes an authorization for one concurrent user. Authorizations for additional concurrent users may be acquired separately.

The intent of the concurrent user pricing with no server fee is to base cost on each user receiving value from Communications Server for Linux, while allowing flexibility in defining and modifying the number of servers used. For example:

  • When TN3270 clients are connected to Communications Server for Linux TN3270 server, each concurrent TN3270 client is one user. If one person has multiple emulation sessions that are connected in through the same IP address, that is still one user; if multiple people go through one proxy to connect to the server, each person is a user. Some specific examples for TN3270 clients are as follows:
    • When 100 end users using TN3270 clients for display and printer go through Communications Server for Linux TN3270 server, it is 100 user licenses.
    • When 100 end users go through two Windows Terminal Server with TN3270 clients and go through Communications Server for Linux TN3270 Server, it is 100 user licenses.
    • When end users use Web browsers via Host Access Transformation Services (HATS) to access the Communications Server for Linux TN3270 Server, it is the number of concurrent TN3270 clients (that is, Host On-Demand (HOD) is used by HATS to communicate to the Communications Server for Linux TN3270 server). Therefore, if 100 HOD clients are defined to HATS, then it is 100 user licenses.
  • User scenarios include downstream SNA clients, Web clients, Remote API client/server, SNA Gateway, network node, and application clients using Communications Server for Linux application interfaces to connect to host mainframe or other SNA applications. In these scenarios, each end-user client is one user. When multiple people go through one proxy or go through middleware applications to Communications Server for Linux application interface, each person is a user. Some specific examples for SNA clients are as follows:
    • When 100 end-user SNA clients running HACP (Personal Communications) go through Communications Server for Linux SNA Gateway, network node, or remote API client/server, it is 100 user licenses. If those 100 end users go through two Linux Communications Servers for load balancing or backup, it is still 100 user licenses
    • When 100 end-user TCP/IP clients go to a single TCP/IP-based middleware application server that uses Communications Server for Linux application interface to communicate to CICS®, IMS™, or some other SNA applications, it is 100 user licenses. When 5000 end users using a Web browser go to a middleware Web Server-based application server that uses 100 SNA sessions through Communications Server for Linux application interface to communicate to CICS, IMS, or some other SNA application, it is still 100 concurrent user licenses.
    • When 100 end users go to a middleware application server using a remote API client and another set of 100 end users go to a different middleware application server also using another remote API client, both middleware application servers go through a common CS Linux Server; it is 200 user licenses.
