I have migrated SSIS project from SQL server 2017 to SQL Server 2019. In this project connection strings are loaded dynamically from database - there are always 8 databases through which it iterates. After migration to SQL 2019 I periodically receive this error message - "Format of the initialization string does not conform the the OLE DB specification". Does anyone have experienced something similar? Please take into account that it periodically works and periodically fails regardless of which connection string it is. I am able to run everything withpout errors and sometimes it stops with this error. All connection strings are in the following format:
Data Source=XXXXXDB01;User ID=username;Password=psw;Initial Catalog=db;Application Name=MyApp;Provider=SQLNCLI11.1;
There is already question about the same issue however there is no clear solution. https://learn.microsoft.com/en-us/answers/questions/662740/ssis-project-connection-manager-connection-string.html?childToView=1102134#comment-1102134
