Currently the on-premises gateway opens more Oracle connections that we have license for.
I believe you can do this by modifying the gateway config file per this posting: https://powerbi.microsoft.com/sv-se/blog/on-premises-data-gateway-january-update-is-now-available/ Summary: Here are the steps to change this configuration: On the gateway machine, open the file: [Program Files]\On-premises data gateway\Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config Find the “MashupDefaultPoolContainerMaxCount” setting. Change its value to the desired value. Save and restart the gateway. Changing this property value to 1 means that all queries will run sequentially, which could be desired for specific data sources that don’t support or don’t perform well with concurrent requests.
