ptx/SNA LU6.2 (APPC) is a layered software product. Layered product installations are described in the DYNIX/ptx and Layered Products Software Installation Release Notes. Perform all of the necessary steps in these release notes and also do the following steps when you install the software packages:
Install the ptx/SNA LU6.2 product. The package name for this software is BrxLU62.
Install the ptx/SNA APPC product, if necessary. The package name for this software is BrxAPPC.
Check the following table, which lists all of the package names and the corresponding directories and files:
Application |
Package Name |
Directory/Files |
ptx/SNA LU6.2 Server |
BrxLU6.2 |
/usr/local/brixton/BrxLU6.2/* /usr/local/brixton/BMD/BCFG_msglib /usr/local/brixton/BMD/BSSP_msglib /usr/local/brixton/BMD/CSRV_msglib /usr/local/brixton/BMD/LU62_msglib /usr/local/brixton/BMD/XSVC_msglib |
ptx/SNA APPC |

/usr/local/brixton/BrxAPPC/* |
The installation procedure is now complete.
ATTENTION Since the ptx/SNA LU6.2 Server V4.7.0 product can affect certain kernel configuration parameters, you may have to reconfigure the kernel, recompile a new kernel, and reboot the new kernel. Refer to the ptx/SNA PU2.1 Base Server V4.7.0 Release Notes for details.
During the installation of BrxLU62, you will be prompted for service names and port numbers for additional entries into /etc/services. If multiple servers will be running concurrently, these values should be supplied at this time or after the installation is complete.
The LU6.2 server is started automatically when the PU2.1 server is started, if LUs of Type 6.2 are present in the configuration and the -1 switch was NOT used to start the PU2.1 server.
Do not start the LU6.2 server by itself.
As part of initialization during startup, the LU6.2 server establishes a socket connection between itself and the PU2.1 server for each LU of Type 6.2 that is defined in the configuration.
Multiple LU6.2 servers will be active on the same system if and only if all of the following conditions apply:
Multiple PU2.1 servers have been started.
The configurations associated with each PU2.1 server contain LUs of Type 6.2.
The PU2.1 servers were NOT started with the -1 switch.
Each LU6.2 server is associated with one and only one PU2.1 server. Each PU2.1 server may be associated with one and only one LU6.2 server.
Refer to the ptx/SNA PU2.1 Base Server V4.7.0 Release Notes for more details.
Programs using the APPC library must be linked with the SVR4 switch, as in the following example:
cc -i -DSVR4 -c program.c
