Prior to installing WSO2 Enterprise Integrator, make sure that the appropriate prerequisites are available. Verify that the computer has the supported operating system and development platforms before starting the installation.

System requirements

Physical

3 GHz Dual-core Xeon/Opteron (or latest)
4 GB RAM (2 GB for JVM and 2 GB for the operating system)
10 GB free disk space
~ Recommended minimum - 2 Cores. For high concurrencies and better performances - 4 Cores.

Disk space is based on the expected storage requirements that are calculated by considering the file uploads and the backup policies. For example, if three WSO2 product instances are running in a single machine, it requires a 4 GHz CPU, 8 GB RAM (2 GB for the operating system and 6 GB (2 GB for each WSO2 product instance)) and 30 GB of free space.

Virtual Machine (VM)

2 compute units minimum (each unit having 1.0-1.2 GHz Opteron/Xeon processor)
4 GB RAM
10 GB free disk space
One CPU unit for the operating system and one for JVM.

Three WSO2 product instances running would require VM of 4 compute units, 8 GB RAM, and 30 GBfree space.
~ 512 MB 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.

EC2

One c5.large instance to run one WSO2 product instance.

Environment compatibility

Operating systems/ Databases

By default, WSO2 EI is installed (through the Installer) with OpenJDK, which allows you to run the product as soon as it is installed.

If you install the product using the binary instead of the installer, or if you are using the installer but want to use a JDK other than OpenJDK, be sure to point the JAVA_HOME environment variable to the new JDK. Make sure your JDK version is compatible with the WSO2 product.
All WSO2 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. Also, 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, contact us.
