I now use CdataSync to transfer ActianZen database data to Bigquery through Btrieve Connector.
1. Even after the data transfer is completed, if you view it in ActianZen's Monitor, it still exists in ActiveFile, that is to say, the resources have not been released.
2. The open mode of the file whose resources have not been released is not the readonly mode, but the normal mode.
Because of the above problems, table lock occurs on the system operation page using the ActianZen database.
If you know how to solve it, or how I should try to solve it, please tell me, thank you very much.
