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.
- ~ 2 GB minimum
- ~ 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.
- ~ 500 MB, excluding space allocated for log files and databases.
Also, we do not recommend or support OpenJDK.
Operating Systems / Databases
- All WSO2 Carbon-based products are Java applications that can be run on any platform that is Oracle JDK 7/8 compliant.
- All WSO2 Carbon-based 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.
The following applications are required for running the product and its samples or for building from the source code. Mandatory installations are marked with an asterisk *.
Oracle Java SE Development Kit (JDK)*
JDK 7 or 8.
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.
- Open the
catalina-server.xml file from the
compression parameter (under each of the connector configurations) to false as shown below:
- Restart the server.
- Oracle and IBM JRE 1.7 are also supported when running (not building) WSO2 products.
- To enable the product's JMS transport and try out JMS samples if any. The ActiveMQ client libraries must be installed in the product's classpath before you can enable the JMS transport.
5.5.0 or later
If you use any other JMS provider (e.g. Apache Qpid), install any necessary libraries and/or components.
- To compile and run the product samples.
