Hi Joe,
Oracle Server 10.2.0.3, with *11.1.0.6* drivers (I didn't have the older ones handy)
Unless I am misunderstanding, I couldn't even duplicate your test case using JDBC drivers. I didn't use terminal input with waits, I just embedded a sleep call that gave me time (two minutes) to run the second insert in SQL*PLUS...
import java.sql.*;
public class testForJoe {
public static void main(String args[]) {
try {
Class.forName("oracle.jdbc.driver.OracleDriver"); Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@xxx", "xxx", "xxx"); System.out.println(conn.getMetaData().getDriverVersion()); Statement stm = conn.createStatement(); stm.execute("truncate table test"); System.out.println("Executed first truncate..."); Thread.sleep(120000); stm.execute("truncate table test"); System.out.println("Executed second truncate...");}
catch(Exception e) {
e.printStackTrace();
}
}
}
...with the output below...
C:\java>java testForJoe
11.1.0.6.0-Production
Executed first truncate...
Executed second truncate...

...and the SQL*PLUS session, with steps taken in the order you
requested...
