Try to run code that connects do Informix database but also shows full exception info and create trace files. One trace file is for JDBC, one is for Informix. Change URL to database, username and password, and run it. You will probably see the problem on screen or in trace file:
import java.io.FileWriter;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
class informix_trace
{
public static void main(String[] args)
{
try
{
Class.forName("com.informix.jdbc.IfxDriver");
FileWriter fwTrace = new FileWriter("c:\\JDBCTrace.log");
PrintWriter pwTrace = new PrintWriter(fwTrace);
DriverManager.setLogWriter(pwTrace);
String debug_url = "SQLIDEBUG=C:\\sqlidebug.trace";
String url = "jdbc:informix-sqli://1.2.3.4:9088/test_db:informixserver=ol_testifx;DB_LOCALE=pl_PL.CP1250;CLIENT_LOCALE=pl_PL.CP1250;charSet=CP1250;" + debug_url
Connection connection = DriverManager.getConnection(url, "user", "passwd");
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT FIRST 1 DBINFO('version','full') FROM systables;");
while (resultSet.next())
System.out.println(resultSet.getObject(1));
}
catch (Exception e)
{
e.printStackTrace();
}
}
} // class informix_trace
Informix trace file will be with some postfix (timestamp or similar info) and in my case it was something like sqlidebug.trace1391758523500.0
. It is binary but you can analyze it using sqliprt
utility.
Example of my session with wrong database name:
c:\>sqliprt sqlidebug.trace1391758523500.0
SQLIDBG Version 1
...
S->C (12)
SQ_ERR
SQL error..........: -329
ISAM/RSAM error....: -111
Offset in statement: 0
Error message......: "" [0]
SQ_EOT
In JDBCTrace.log
I can found more interesting info (I see it also on my screen):
SQLState(IX000) vendor code(-111)
java.sql.SQLException: ISAM error: no record found.

(I have translated it from Polish so it can be little different)
