Summary of Migrating from TN3270 Release 4
to TN3270 Release 6
The following summary helps you determine the migration steps that
you need to take. Depending on the TN3270 functions that you use, you
may not need to perform all of the steps. To migrate from TN3270
Release 4 to TN3270 Release 6, perform the following steps:
Step 1. Use the configuration migration program tnmigrate to modify the
running TN3270 configuration file /etc/opt/tn3270/com.cfg and any
other TN3270 configuration files that you use. Migrating the
configuration files enables you to use the new log message types in
TN3270 Release 6.
To learn how to run the configuration migration program and to
understand the changes it makes to the configuration file, see “Modifying
Configuration Files”.
Step 2. Because the tnmigrate program changes the existing configuration text
files, run the tncfgtcp program to convert them to TN3270 Release 6
binary configuration files. For more information about the tncfgtcp
program, see “Creating a Binary Configuration File”.
Step 3. Review any tools or processes that you have developed for use with
TN3270 log or trace files to determine if they need modification to reflect
changes in the TN3270 log file format. To understand how the log file
format has changed from Release 4 to Release 6, see “Log Messages and
Log File Format”, and “Trace File Format”.
Modifying Configuration Files
TN3270 Release 6 classifies log messages into three categories (audit,
exception, and problem) and allows you to specify in your configuration
file whether audit or exception (or both) logs are recorded. For more
information about these three log message types, see Chapter 4, “Using
TN3270 Log Messages.” TN3270 Release 4 classifies log messages by
level (6, 8, 10, 12, and 16) and allows you to specify the minimum level to
record.
Before using an existing Release 4 configuration file with Release 6, you
need to modify it to take account of this change. TN3270 provides a
