Data Engine Proxy Services

The Data Engine Proxy Services support intercommunication from a Data Engine and the Data Engine OMAS. Where a Data Engine is unable to handle this communication directly, a proxy can be written for the Data Engine that runs server-side in OMAG Server Platform and brokers calls to the Data Engine itself into calls back to the Data Engine OMAS. This set of proxy services configures such a proxy to run server-side within the OMAG Server Platform.

OMAG Server Platform configuration

1. Start an OMAG Server Platform

2. Configure the Data Engine Proxy:

   POST following JSON object (following shows an example for IBM DataStage)

   {
       "class": "DataEngineProxyConfig",
       "accessServiceRootURL": "http://localhost:8080",
       "accessServiceServerName": "omas",
       "dataEngineConnection": {
           "class": "Connection",
           "connectorType": {
               "class": "ConnectorType",
               "connectorProviderClassName": "org.odpi.egeria.connectors.ibm.datastage.dataengineconnector.DataStageConnectorProvider"
           },
           "endpoint": {
               "class": "Endpoint",
               "address": "myhost.somewhere.com:9445",
               "protocol": "https"
           },
           "userId": "igcuser",
           "clearPassword": "igcpassword"
       },
       "pollIntervalInSeconds": 60
   }

   to the following address

   http://localhost:8080/open-metadata/admin-services/users/{{user-name}}/servers/{{server-name}}/data-engine-proxy-service/configuration
   

   The object dataEngineConfig is the information required to implement the specific proxy connector to the data engine. The keys should be modified based on the information needed by the connector.

3. Start the instance of the OMAG Server Platform

   POST to the following address

   http://localhost:8080/open-metadata/admin-services/users/{{user-name}}/servers/{{server-name}}/instance
