Optimize OpenMRS for Memory Usage on OpenSRP/OpenMRS Instances

[morrismukiri]

• 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
