See also Adabas Database Management Interfaces ADA and ADA2 in the Programming Guide.

Parameter	Description

Changes and Enhancements

Natural Web I/O Interface Daemon

Logging

An enhanced logging information system is now provided. See Logging Information in the Natural Web I/O Interface documentation.

Daemon Commands

In addition to editing the configuration file nwosrvd.conf, it is now also possible to configure the Natural Web I/O Interface daemon by specifying commands at the UNIX command prompt. See Natural Web I/O Interface Daemon Commands in the Installation documentation.

Natural Web I/O Interface Client

Java Version for Java EE-based Server

The prerequisite for using the Natural Web I/O Interface client on a Java EE-based server has changed. It is now required that Java Runtime 5 or above is installed.

Tracing

It is now possible to define a different trace directory for IIS.

It is now possible to enable tracing for a session on a Java EE-based server (Sun Application Server and JBoss Application Server). To do so, you set the trace attribute in a session definition to "true".

Logging

In case of problems with the Natural Web I/O Interface client or Natural for Ajax on a Java EE-based server, you can now enable logging and thus write the logging information to an output file. See Logging in the Natural Web I/O Interface documentation.

Notice of Future Changes

The following changes are planned for future versions of Natural.

Default Setting for Adabas Database Driver

With Natural Version 6.3.4, the database driver ADA is still used by default.

With a future version of Natural, the default setting for the database driver will change to ADA2.

Handling of the TF Parameter

With a future version of Natural, the handling of the TF parameter will be changed.

Currently, it is only possible to use the asterisk (*) notation for the database ID (DBID) and file number (FNR) of the production database. In a future version, it will also be possible to use the asterisk notation for the database ID and file number of the test database. It may then be possible that your applications will behave in a different way.
