Hi
Thanks for reaching out to Microsoft Q&A.
From the error it seems the ADF is unable to fetch connection to the oracle database since there are multiple other processes already running (Resource busy/timeout). You cannot get the SID/ProcessID details from the ADF error.
Can you check if you are using the correct & existing database and table names? I trying to see why there it waits and times out instead of connecting instantly which should be the case unless there is truly resource contention from the oracle database.
One way is to try with him to filter out by the loginname(that you are using to connect oracle), I know this might not work all the time because there might not be a unique login for ADF in most cases.
