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

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 GB free 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

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

Environment compatibility

Operating systems/ Databases

All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 1.8 compliant. Note that OpenJDK 1.8 is also supported.

For more information on JDKs that WSO2 products are tested with, see Tested Operating Systems and JDKs.
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.

Required applications

The following applications are required for running WSO2 Enterprise Integrator and its samples. Mandatory installs are marked with *.

Application	Purpose	Version	Download Links
Oracle Java SE Development Kit (JDK)*	To launch the product. To launch WSO2 Enterprise Integrator, you need to have Oracle JDK 1.8.* or OpenJDK 1.8.. However, to have the Nashorn JavaScript engine support for the Script Mediator, you need to use JDK 8 version update 112 or later*. To run Apache Ant.	1.8.* Important! Some updates of JDK 1.8 (for example, JDK1.8.0_151) are affected by a known issue related to GZIP decoding. Until this issue is fixed, we recommend one of the following approaches: To find out if this version of the product has issues running on your OS due to the JDK version, see Known Incompatibilities. 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
Apache Ant	To compile and run the product samples.	1.7.0 or later	http://ant.apache.org
Apache Maven	To build the product from the source distribution (both JDK and Apache Maven are required). If you are installing by downloading and extracting the binary distribution instead of building from the source code, you do not need to install Maven.	3.0.x	http://maven.apache.org
Web Browser	To access each product's Management Console. The Web Browser must be JavaScript enabled to take full advantage of the Management console. On Windows Server 2003, you must not go below the medium security level in Internet Explorer 6.x.
