Installation Prerequisites

Prior to installing any WSO2 Carbon based product, it is necessary to have the appropriate prerequisite software installed on your system. Verify that the computer has the supported operating system and development platforms before starting the installation.

System requirements

Memory	~ 2 GB minimum ~ 512 MB heap size. This is generally sufficient to process typical SOAP messages, but the requirements vary with larger message sizes and the number of messages processed concurrently.
Disk	~ 1 GB minimum (excluding space allocated for log files and databases.)

Environment compatibility

Operating Systems / Databases

All WSO2 products are Java applications that can be run on any platform, that is Oracle JDK 1.6.*/1.7.* compliant.
All WSO2 products are generally compatible with most common DBMSs. For more information, see Working with Databases.

For BAM Hive metadata storage, Oracle is not supported and it is recommended to use MySQL or H2, since BAM is successfully tested on the compatibility with those. Also H2 is not recommended for a production setup.
If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us.

Required applications

The following applications are required for running the BAM and its samples, or for building from the source code. Mandatory installs are marked with *.

Application	Purpose	Version	Download Links
Oracle Java SE Development Kit (JDK)*	Required to; launch the product as each product is a Java application. build the product from the source distribution (both JDK and Apache Maven are required). run Apache Ant.	1.6.* / 1.7.* If you are using JDK 1.6, you might need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy files to avoid `illegal key size` errors, when you try to invoke a secured web service. To build the product from the source distribution, you must use JDK 1.6 instead of JDK 1.7. Oracle and IBM JRE 1.7 are also supported when running (not building) WSO2 products. If you are using JDK7 on Mac OS, follow the steps below to install the Snappy-java library`:` Download the Snappy JAR file from here, and extract it to a preferred location. We will refer this extracted folder as `<SNAPPY_HOME>.` In `<SNAPPY_HOME>/org/xerial/snappy/native/Mac/` folder, you find the Snappy java library files (.jnilib files) as i386 (32bit) and x86_64 (64bit). Copy the appropriate one to `<BAM_HOME>.` For more information on installing snappy-java library, see Snappy-java fails on Mac OS JDK 1.7.	http://java.sun.com/javase/downloads/index.jsp
Apache Ant	To compile and run the product samples.	1.7.0 or later	http://ant.apache.org
SVN Client	To check out the code to build the product from the source distribution. If you are installing by downloading and extracting the binary distribution instead of building from the source code, you do not need to install SVN.		Linux - http://subversion.apache.org/packages.html Windows - http://tortoisesvn.net/downloads.html
Apache Maven	To build the product from the source distribution (both JDK and Apache Maven are required). If you are installing by downloading and extracting the binary distribution instead of building from the source code, you do not need to install Maven.	3.0.*	http://maven.apache.org
Web Browser	Required by all WSO2 products to access each product's Management Console. The Web Browser must be JavaScript enabled to take full advantage of the Management console. On Windows Server 2003, you must not go below the medium security level in Internet Explorer 6.x.
*Cygwin (mandatory for Windows)**	BAM analytics framework depends on Apache Hadoop and Hadoop requires Cygwin, in order to run in Windows. At a minimum; Basic, Net (OpenSSH, tcp_wrapper packages), and security related Cygwin packages need to be present in the system. After installing Cygwin, update your `PATH` variable by appending "`;C:\cygwin\bin`". This is required since the default installation of Cygwin might not do this.	1.7.0 or later	http://www.cygwin.com
