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.

...

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

title Note
WSO2 Enterprise Integrator is also compatible with IBM JDK 1.8.*. For more information on the IBM-specific configurations that you need to do when starting different profiles of WSO2 EI, see Running the Product. Also, for more information on JDKs that WSO2 products are tested with, see Tested 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 Changing the Default Databases. 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.

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:

Use either JDK1.8.0_144 or JDK1.8.0_077 updates. We have verified that these versions are not affected by the known issueTo 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.
1. 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).
2. Set the compression parameter (under each of the connector configurations) to false as shown below:
  Code Block
  compression="off"
3. Restart the server.
