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	~ 8 GB minimum is recommended. About 6GB of memory is allocated to the Carbon JVM and Spark. The balance is used by the operating system. In a distributed deployment, Spark is run in a seperate JVM. It is recommended to allocate 4GB of memory for Carbon JVM and 2GB for Spark. ~ 4 GB heap size.
Disk	~ 10 GB minimum (excluding space allocated for log files and databases.). The disk space required depends on the amount of index data that needs to be stored.
Cores	A minimum of 4 CPU cores are recommended. A lower number may affect performance.

Environment compatibility

Operating Systems / Databases

All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 1.7.*/1.8* compliant. Also, we do not recommend OpenJDK as we do not support it or test our products with it.
All WSO2 products are generally compatible with most common DBMSs. For more information, see Working with Databases.
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.
