Git Project

Orcas is managed in an own Repository on GitHub. So you can get your own local git-Clone or just download as ZIP file.


Orcas comes with a Vagrant configuration to easily set up a VM, in which Orcas is directly runnable (including database). For an installation of the required tools on Linux you can have a look at this to get an idea.

The Vagrant-VM is only intended for tests. To use Orcas in your own project you have to install the following tools:

Tools needed


Java 8 (1.8) needed at least. Important: It has to be a JDK and not a JRE. The “Standard Edition” (SE), e.g. “Java SE Development Kit 8u131”, is ok. After the installation you should get the right version with javac:

javac -version
javac 1.8.0_121

If not, you maybe have to adapt the PATH variable. In Orcas, Java is used by ant and gradle, so maybe you have to consider the configuration possibilities (e.g. ant interprets JAVA_HOME before PATH). Download link for Java 8: Download


To find at Until further notice you can use the newest version (to find at “Download Binary Distributions”).
Download, extract (e.g. to “C:\Program Files\apache-ant-1.9.4”), create system variable ANT_HOME and take path as value, create user variable PATH (or extend) with “%ANT_HOME%\bin;%JAVA_HOME%\bin;” as value (without quotation marks).
Test of ant: use command line with ant -version. Now you should be able to read something like “Apache Ant(TM) version 1.9.4 compiled on April 29 2014”.


Important: The newest version is not the right version! The last working version is ant-contrib-1.0b3.jar. To find at Download ZIP, extract, copy “ant-contrib-1.0b3.jar” (other files are not relevant!) to ANT_HOME/lib.


To find at Until further notice you can use the newest version.
Download, extract (e.g. to “C:\Program Files\gradle-2.3”).
The command gradle has to be included in PATH, or GRADLE_HOME has to be set.
Maybe Gradle connects to Maven Central repository, which means there has to be a working internet connection.


SQL*Plus has to be executable on the command line. tnsping on the target database has so work, too. Orcas essentially always uses TNS and SQL*Plus, just a few addition features (e.g. dbdoc) are using JDBC. ORACLE_HOME has to be set.

ORACLE Thin Client

It is possible to use the Instant-Client. If you do, ORACLE_HOME has to be set to the instant client directory. ORACLE_HOME is currently only used to get the JDBC driver. You need the “Basic”-Package and the “SQL*Plus”-Package. Usually there is no tnsping in the Instant Client. So you need to test the setup with a successful SQL*Plus connect. To use a tnsnames.ora with the Thin Client you manually have to create this in the directory ORACLE_HOME/network/admin (inclusive of the directory) or the TNS_ADMIN variable has to be set appropriately.
