问题 I'm using UCanAccess to connect my JavaFX app with the database on the shared drive. The first time I open the app and run some query the initial connection to the database takes around 25 seconds. I put some timestamps and found that the root cause is the below method, specifically the first try catch block takes 25 seconds to execute. After that, every other time I call this method everything runs within a split of second. Any suggestions on how could this be resolved? public void openDB(){

问题 Because the jdbc odbc bridge is no longer available (see this question/answer), I tried UCanAccess, which works great reading the database, but on Windows 10, throws an error on a write attempt: ( [CONCURRENT_PROCESS_ACCESS] - File marked as read only.

I am currently unable to tinker since I don't have a Windows 10
