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	1 GB minimum A heap size of around 512MB is generally sufficient to process typical SOAP messages Requirements may vary with larger message sizes and on the number of messages processed concurrently
Disk	~ 1 GB minimum (excluding space allocated for log files and Databases.)

Environment Compatibility

Operating Systems / Databases / Application Servers

All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 1.6.*/1.7.* compliant.
All WSO2 Carbon-based products are generally compatible with most common DBMSs.

For BAM Hive metadata storage, Oracle is not supported and we recommend to use MySQL or H2, since BAM is successfully tested on the compatibility with those.
It is not recommended to run WSO2 BAM on Windows since Hadoop is not optimized for Windows.
It is not recommended to use Apache DS in a production environment due to issues with scalability. Instead, it is recommended to use an LDAP like OpenLDAP for user management.
For environments that WSO2 products are tested with, see Environments Tested with WSO2 Products.

Required Applications

Application	Purpose	Version	Notes
Java SE Development Kit (JDK)	To launch the product as each product is a Java application. To build the product from the Source distribution (both JDK and Apache Maven are required). To run Apache Ant.	1.6.x or higher If you are using JDK 1.6, you might need to replace the Java Cryptography Extension (JCE) policy files in your JDK with the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy files. This will 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 supported when running (not building) WSO2 products. We do not recommend OpenJDK. 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.	Required by all WSO2 products
Apache Ant	To compile and run the sample clients.	1.7.0 or later	Required by all WSO2 products to run product samples
Apache Maven	To build the product's source. (both JDK and Apache Maven are required).	2.1.0 or later	Required by all WSO2 products when installing from source distribution
SVN Client	To checkout WSO2 Carbon source from `http:` `//svn.wso2.org/repos/wso2/carbon/kernel/branches/4.0.0 wso2carbon` .	Can be downloaded from; http://tortoisesvn.net/downloads.html	Required by all WSO2 products
Web Browser	To access the product's Management Console. The Web Browser must be JavaScript enabled to take full advantage of the Management console. On Windows Server 2003, it is not allowed to go below the medium security level in Internet Explorer 6.		Required by all WSO2 products
Cygwin	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 Can be downloaded from; http://www.cygwin.com	Required by WSO2 BAM running on Windows
