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

  • As all WSO2 Carbon-based products are Java applications, it is generally possible to run them on most operating systems. These include Windows, Linux, Solaris, Ubuntu, Fedora, Mac OS X, Gentoo, SUSE, Debian etc. with a JDK 1.6.x runtime.
  • However, Linux/Solaris is recommended for a production deployment of WSO2 BAM since Hadoop (used for analytics engine in BAM) is not recommended to be run in Windows based systems in production settings. (http://hadoop.apache.org/common/docs/r0.20.2/quickstart.html#PreReqs).
  • All WSO2 Carbon-based products are generally compatible with most-common DBMSs such as MySQL, MS SQL Server, Oracle, H2, DB2, Derby, PostgreSQL.  
  • 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

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 (JDK 1.7 is supported from this release onwards)

  • 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 JRE 1.7 supports when running (not building) WSO2 products.

If you are using JDK7 on Mac OS, follow the steps below to install the Snappy-java library: 

  1. Download the Snappy JAR file from here, and extract it to a preferred location. We will refer this extracted folder as <SNAPPY_HOME>.
  2. 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.
