When set jar run on scheduled time, jar failed to connect Oracle,
or when program start running, and when I returned to my PC, sometime will drop connection and this error message come out.
but it is success when run jar manually.
Is it this is due to Oracle setting issue?
connection: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource.
java.sql.SQLException: The Network Adapter could not establish the connection
