TNS: connection closed ORA-12537

[Romancu]

Hello, 

my Semantic model is using multiple data sources. One of those is Oracle ODBC.

If i refresh data using PBI Desktop everything is working. 

But my published version in Service is giving me this error after trying to refresh data :

Data source error{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details":[{"code":"DM_ErrorDetailNameCode_UnderlyingErrorCode","detail":{"type":1,"value":"-2147467259"}},{"code":"DM_ErrorDetailNameCode_UnderlyingErrorMessage","detail":{"type":1,"value":"ODBC: ERROR [HY000] [Oracle][ODBC][Ora]ORA-12537: TNS: connection closed\n\r\nERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed\r\nERROR [HY000] [Oracle][ODBC][Ora]ORA-12537: TNS: connection closed\n"}},{"code":"DM_ErrorDetailNameCode_UnderlyingHResult","detail":{"type":1,"value":"-2147467259"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourceKind","detail":{"type":1,"value":"Odbc"}},{"code":"Microsoft.Data.Mashup.ValueError.DataSourcePath","detail":{"type":1,"value":"dsn=SPINSK64"}},{"code":"Microsoft.Data.Mashup.ValueError.OdbcErrors","detail":{"type":1,"value":"#table({\"SQLState\", \"NativeError\", \"Message\"}, {})"}},{"code":"Microsoft.Data.Mashup.ValueError.Reason","detail":{"type":1,"value":"DataSource.Error"}}],"exceptionCulprit":1}}} Table: XYZ 

Every time i tried to refresh this error came up but with different Table name  ( XYZ, ABC, ...)

But when i try to refresh it 4th 5th time the refresh will take place in order with no error.  This problem is causing me complications because of Schedule refresh.

Has anyone encountered a similar problem?

Thanks

Hi @Romancu ,

TNS: connection closed error you're encountering with your Oracle ODBC data source in Power BI Service. This error typically indicates a problem with the network connection between the Power BI service and your Oracle database, or a configuration issue on the Oracle server side.

• Ensure that the on-premises data gateway is properly configured and running. The gateway facilitates the connection between Power BI Service and your on-premises data sources.Manage your data source - Oracle - Power BI | Microsoft Learn
• The ORA-12537 error can sometimes be caused by the Oracle listener not running or being misconfigured. Verify that the Oracle listener is running and properly configured to accept connections from the Power BI service.TNS-12537 - Database Error Messages (oracle.com)
