These release notes support Version 4.6.0 of the ptx®/SNA RJE (3770) software. Read this document before installing this software on your NUMA-Q® or Symmetry® system.
The software installation procedure is documented in the DYNIX/ptx® and Layered Products Software Installation Release Notes. Read these release notes thoroughly before installing the ptx/SNA RJE (3270) software.
The following software product is a prerequisite for the ptx/SNA RJE (3770) V4.6.0 software:
ptx/SNA PU2.1 Base Server V4.6.0 and its prerequisites (refer to the ptx/SNA PU2.1 Base Server V4.6.0 Release Notes).
ptx/SNA RJE (3770) V4.6.0 will now run in a threaded environment. However, the product does not support threaded operations.
ptx/SNA RJE (3770) 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 select the package for the ptx/SNA RJE (3770) software. The package name for this software is Brx3770.
Check the following table, which lists the package name and the corresponding directories and files:

The installation is now complete.
Include the following in your path:
Refer to the following table when planning the number of processes for each RJE (3770) application you intend to use.
Application |
Processes |
Brx3770 |
1 per remote RJE workstation. There can be multiple Brx3770 processes associated with a single brxpu2.1 process if multiple PUs are running RJE from the same configuration file. |
brx3770 |
6 per remote RJE workstation. |
All ptx/SNA RJE (3770) executables are executed with brxrje as the effective user, including the postprocessing script. The directory in which Brx3770 is started (directly or using BrxCmd startup) must have read/write permission for brxrje.
The ptx/SNA RJE (3770) product can be used in the following usage models:
A single-user model, where the one user using ptx/SNA RJE is root, brxrje, or a non-root user.
A multiuser model, where t here is one user starting up ptx/SNA RJE, but more than one user adding, deleting, and changing jobs.
In the latter case, do not start ptx/SNA RJE as root because you want to avoid running postprocessing scripts with a real user ID of root (effective user ID will be brxrje).
Start ptx/SNA RJE as a non-root user. If an explicit spool directory is not supplied, the current directory will be used as the spool. Ensure that the spool directory is writeable for all users who will submit jobs to this server.
When submitting, deleting, and changing jobs, users must use the defaults unless they know either the server name or the spool directory. Make sure that users have this information if they need it.
Multiuser usage in a multiserver environment.
In case you have ptx/SNA RJE (3770) running on multiple servers (more than one PU2.1 Server, and ptx/SNA RJE (3770) started on each server), you must choose a different spool directory for each invocation of ptx/SNA RJE (3770). You should also distinguish the spool directory using the PU2.1 Server name (specified in the SERVICES section of the configuration).
In this case also, do not start ptx/SNA RJE (3770) as root. Use a different spool directory for each of the servers. Supply the name of the spool directory or server to users who are submitting, deleting, or changing jobs, so that they can specify the appropriate spool directory.
When a single PU2.1 Server has multiple PUs running ptx/SNA RJE (3770), the JOB Queue commands (such as BrxCmd addq, or BrxCmd listq) must supply the name of the spool directory. Supplying the server name or using defaults will not work in this case since there are multiple spools associated with a single server.
