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.

...

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. 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.

Oracle Java SE Development Kit (JDK)*

Note
titleNote

To launch WSO2 DAS, you need to have Oracle 1.8.*. You cannot launch WSO2 DAS with Oracle JDK 1.7.* or lower.

1.8.*

Note
titleImportant!

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 issue.
  • 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 from the <DAS_HOME>/repository/conf/tomcat/ directory.

    2. Set the compression parameter (under each of the connector configurations) to false as shown below:

      Code Block
      compression="off"
    3. Restart the server.


Info

We do not recommend OpenJDK as we do not support it or test our products with it.

JDBC-compliant Connector for JavaRequired as a standardized database driver for Java platforms and development.1.7.0 or laterhttp://dev.mysql.com/downloads/connector/

Apache Ant

To compile and run the /wiki/spaces/PS/pages/10519862.

1.7.0 or later

http://ant.apache.org
Git

Required to check out the source from the Git repository.


1.9.0 or later

http://git-scm.com/downloads/

Apache Maven

To build the product from the source distribution (both JDK and Apache Maven are required).

Info

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.*

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.

Info

WSO2 DAS does not support Internet Explorer 10 and older versions.



Info

In order to avoid the NoClassDefFoundError exception when running the C++ code embedded in WSO2 DAS and other WSO2 DAS-based products, install glibc package in the operating system.

For detailed installation guidelines in Alpine Linux , see alpine-pkg-glibc.

Then download snappy-java from here and copy it to the <PRODUCT_HOME>/repository/components/lib directory.

Tip

The path specified above changes depending on the Analytics profile for which you are doing this installation.

e.g., For EI Analytics, the directory in which you need to place the snappy-java package is <EI_HOME>/wso2/analytics <EI_HOME>/wso2/analytics/repository/components/lib directory.
