  • Manage Scheduler: By default OpenMRS runs two scheduled jobs Auto Close Visits Task and Process HL7 Task which are expensive and we don't currently require/utilize this services.
    Stopping or entirely deleting this jobs is recommended
  • Trim down unused Modules: OpenMRS comes pre-loaded with recommended modules, however for the purpose we use OpenMRS for not all this are required
    -Required modules for OpenSRP
    • ID Generation
    • OpenMRS UI Framework
    • Address Hierarchy
    • Registration Core Module
    • Event Module
    • Provider Management Module
    • Team Management Module
    • UI Commons Module
    • Rest Web Services OMOD
    • Legacy UI Module
    • UI Library Module
  • Decrease logging for OpenMRS services and OpenMRS tomcat instance: OpenMRS logs most of the services which increases resource usage configuring log levels to high values helps to reduce what is being logged by OpenMRS
  • Patient Identifier Type Management: By default OpenMRS comes with OpenMRS ID required while creating a patient, OpenSRP does not provide for this, while setting up OpenMRS this needs to be disabled or marked as not required
  • Search Index: rebuild the search index
