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.

The config-validation.xml file in the <PRODUCT_HOME>/repository/conf/etc directory contains a list of recommended system parameters, which are validated against your system when the server is started. See Configuring config-validation.xml for details.

System requirements

Memory	~ 2 GB minimum ~ 1 GB 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, excluding space allocated for log files and databases.

Environment compatibility

All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 1.7.*/1.8.* compliant. We do not recommend OpenJDK as we do not support it or test our products with it.
Note

WSO2 ESB is also compatible with IBM JDK 1.7.*/1.8.*. For more information on JDKs that WSO2 products are tested with, see Tested JDKs.
If you want to start WSO2 ESB with IBM JDK, edit the <ESB_HOME>/repository/conf/security/Owasp.CsrfGuard.Carbon.properties file and replace the line org.owasp.csrfguard.PRNG.Provider=SUN with org.owasp.csrfguard.PRNG.Provider=IBMJCE.
All WSO2 Carbon-based products are generally compatible with most common DBMSs. The embedded H2 database is suitable for development, testing, and some production environments. For most enterprise production environments, however, we recommend you use an industry-standard RDBMS such as Oracle, PostgreSQL, MySQL, MS SQL, etc. For more information, see Working with Databases in the Administration Guide. Additionally, we do not recommend the H2 database as a user store.
It is not recommended to use Apache DS in a production environment due to scalability issues. Instead, 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.
