Solutions:
Degugging the root Cause of above Issue:
The error “Caused by: java.sql.SQLException: Io exception: Got minus one from a read call” clearly indicates the root cause of this issue. “We get the following error “Got minus one from a read call” if the Database goes under Maintenance…..or Database is in inconsistent State (Due to any reason like Database Maintenance or Database unmounting…etc ).
WLS is asking a JDBC driver for a connection and getting that exception, which means the DBMS or network dropped the socket during the driver-DBMS handshake.
The above error ensures that there is Nothing Wrong from WebLogic Side …we need to contact the Database Administrator only.
Step1). Open the Server Log and check the timestamp of the first occurance of that Error in the Server log.
Step2). Confirm with the Database Administrator…. What was the activity happening on the Database side at that time (90% cases u will find that the Database might be under Maintenance that time)
