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.* OpenJDK 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 Compatibility of WSO2 Products.
If you have difficulty in setting up any WSO2 product in a specific platform or database, please contact us.
