Communications Server for AIX V6.3 is an evolution of all previous versions of the IBM Communications Server family of products. For details about the functions and capabilities of the Communications Servers, visit
New functions include the following.
TN3270 LU visibility
TN3270 Server client IP addresses are now reported to the host mainframe when the LUs are activated for an SSCP-LU session. This information is needed for the host mainframes to report IP client addresses using LU resources.
Remote API client
Communications Servers running in a domain of servers that support remote API clients can now support SNA applications running on AIX V5, Linux, and Windows platforms. The connection between the clients and the AIX servers is over TCP/IP using HTTPS protocols for additional security. 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 the remote API clients. Interfaces for Communications Server for AIX V4.2, and earlier, are not supported by the remote API client. In a domain with multiple Communications Server for AIX servers, one server holds the master copy of the Communications Server for AIX domain configuration file. This server is known as the master server. You can define other servers in the domain to be backup servers, or leave them as peer servers.
Primary LU support for LU 0, 1, 2 and 3
LUA applications use session level interface (SLI) and request unit interface (RUI) to connect to
host mainframes as secondary LUs. This relationship means that the definition for the sessions is
controlled by the host application, which sends the BIND to start a session. Communications Server
for AIX can now act as a primary LU to downstream SNA-dependent devices over LAN and WAN interfaces
using the RUI_INIT_PRIMARY interface. Also, with this interface, an application can connect
downstream-dependent LU sessions without the need for a host mainframe. Primary LU support is not
available for Enterprise Extender (EE) or Multipath Channel (MPC) connections.

Licensed function Product group Product category title Communications Server App Integration App Integration Middleware Other Middleware Other Charge unit Program name PID number description Communications Server 5765-E51 Server(s) Communications Server 5765-E51 Concurrent User(s) Licensed function Product group Product category title IBM Communications IBM Communications Communications Server for AIX Server Server
The Communications Server for AIX has two charge units: per server and per concurrent user.
A "server" is defined as a machine that runs the program in an instance of the AIX operating system. A separate license for the program is required for each server on which the program is installed.
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 utilize 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 is to base cost on each user receiving value from Communications Server for AIX, while allowing flexibility in defining and modifying the number of servers used. For example:
When TN3270 clients are connected to the Communications Server for AIX 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 the Communications Server for AIX TN3270 Server, it is 100 user licenses.
- When 100 end users go through two Windows Terminal Server with TN3270 clients and go through the Communications Server for AIX 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 AIX 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 AIX's 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 AIX 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 the
Communications Server for AIX 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 the Communications Server for AIX SNA Gateway, network node, or Remote API client/server, it is 100 user licenses. If those 100 end users go through two Communications Server for AIX 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 the Communications Server for AIX application interface to communicate to CICS®, IMS, or some other SNA applications, it is 100 user licenses. When 5000 end users using Web browsers go to a middleware Web server-based application server which uses 100 SNA sessions through the Communications Server for AIX 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 Communications Server for AIX server, it is 200 user licenses.
Charge metrics definitions
"Per server": Any machine on which a program or a component of a program is run. A Proof of Entitlement (PoE) is evidence of your authorization to use a program and is required for each server on which the program is run.
- Programs are "installed" onto a storage device which may or may not be part of the server; thus, "run" is important here as the program may be stored on a CD, SAN, available via SCSI, and so on.
- The number of partitions or processors on the server is irrelevant.
- Where blade technology is employed, each blade is considered a separate server.
Concurrent user: A concurrent user (user) is one individual machine, program, access, or device within or outside your enterprise. A PoE is evidence of your authorization to use a program and is required for each user accessing the program or any program component, either directly or indirectly. (An example of "indirect" access would be through a multiplexing program or an application server through any means on behalf of the user.) You must acquire PoEs to support the "high water mark" of concurrent users the highest number of users accessing the program at any given point of time.
