Preventing the “No more data to read from socket” error

If you use Oracle as the Application Security database, you might see an exception of the type “No more data to read from socket.”

One possible solution to this exception is to do the following:

1. Go to the $ORACLE_HOME/network/admin/ directory.
2. Open the tnsnames.ora file in a text editor.
3. Set the value of SERVER to DEDICATE.
4. To apply the change, restart the active listener associated with the database.
