Installation Prerequisites

Prior to installing WSO2 Micro Integrator, make sure that the appropriate prerequisites are fulfilled.

System requirements

Docker
  • ~512 MB heap size for one Micro Integrator instance. This is generally sufficient for processing typical SOAP messages. However, the requirements vary with larger message sizes and the number of messages processed concurrently.
  • 1 GB memory for a Docker container.
  • Minimum 0.5 core per Micro Integrator Docker instance.
Virtual Machine (VM)/Physical
  • Minimum 0.5 core (1.0-1.2 GHz Opteron/Xeon processor).
  • 1 GB RAM for JVM.
  • ~512 MB heap size. This is generally sufficient for processing typical SOAP messages. However, the requirements vary with larger message sizes and the number of messages processed concurrently.

Environment compatibility

  • The Micro Integrator is installed with OpenJDK by default, which allows you to run the product as soon as it is installed.
  • To use a different JDK, point the JAVA_HOME environment variable to the new JDK. Make sure your JDK version is compatible with the WSO2 product.
  • It is not recommended to use Apache DS in a production environment due to scalability issues. Instead, use an LDAP like OpenLDAP as your user store.
  • If you have difficulty in setting up the Micro Integrator in a specific platform or database, contact us.
