Installation Prerequisites

Prior to installing WSO2 Enterprise Integrator, 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	~ 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 1.8.* compliant.
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, contact us.

Alternatively, you can disable GZIP decoding for your product by following the steps given below. This will ensure that your product is not affected by the known issue. Open the `catalina-server.xml` file in each profile of WSO2 EI. Listed below are the folders that store this file for each profile: ESB profile: `<EI_HOME>/conf/tomcat/` directory. BPS/MB, and Analytics profiles: `<EI_HOME>/wso2/<PROFILE_NAME>/conf/tomcat/` directory (where `<PROFILE_NAME>` is the name of the profile). Set the `compression` parameter (under each of the connector configurations) to false as shown below: compression="off" Restart the server.	http://java.sun.com/javase/downloads/index.jsp
