These release notes cover the following topics:
Please review these requirements before running Pervasive DataRush.
This release has been tested on the following platforms and environments.
Minimum satisfactory performance requires the following:
Run Pervasive DataRush on the latest versions of the following Java releases. A JDK is required rather than a JRE.
Where possible, Sun Java is recommended.
In all cases, 64-bit Java is preferred.
Administrator privileges are required on your local machine to modify the system path environment variable.
The following tools are useful but are not required for Pervasive DataRush application development:
This topic covers the following procedures:
Allow at least 30 MB free disk space for installation.
A trial license can be downloaded from the Pervasive DataRush web site.
Required for Windows, optional for Unix systems.
The Pervasive DataRush bin directory contains the batch script dr.bat and the shell script dr. Both files begin with settings for JVM location and memory usage.
The JVM location is set by JAVA_HOME. If you already have set this variable in your system, leave this setting as is. Otherwise you must enter an absolute path to a Java installation.
For example, in a Windows system, the path can resemble the following:
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_11
JVM options are set by JAVA_ARGS. JVM options are local to the session in which Pervasive DataRush runs. The dr command line script sets a default for maximum memory usage to -Xmx512M (512 MB).
You may also set memory start size, such as -Xms512M.
These settings are for demonstration purposes. For developing applications, we recommend 50 percent of physical memory.
Note: In testing on Sun JVMs, performance is better when ms and mx have the same value. Sun users with a server JVM can use the -server option, which must appear first in JAVA_ARGS.
dr --version or dr -v.On Windows the return should resemble the following:
Product version: Build 4.0.x.xx on YYYY-MM-DD HH:MM:SS PM
Library version: Build 4.0.x.x on YYYY-MM-DD HH:MM:SS PM
Java version: 1.6.0_11 in <JAVA_HOME>\jre
Pervasive DataRush is now installed.
Logging is configured in the file InstallDir/datarush-4.0.2/conf/logger.properties.
In this properties file, see “File Handler Logging Settings.”
Documentation for this release is provided in DataRush Developer’s Guide, command line help, Javadoc, and comments in the property files for the samples.
dr --help or dr -h to see information about run-time options.Once you have installed Pervasive DataRush, we recommend that you try the working sample applications provided with the installation. For each example, all needed files are in InstallDir/datarush-4.0.2/samples.
Product installation includes the following sample applications:
The samples directory also includes Javadoc for the samples.
As a convenience, the installation includes the batch script runsamples.bat for Windows and the shell script runsamples for Unix. Running this script in the samples directory executes all samples and generates output and logging files.
