Code Example:
try{
String driverName = "com.timesten.jdbc.TimesTenClientDriver"; // "sun.jdbc.odbc.JdbcOdbcDriver"
String Url = "jdbc:timesten:client:dsn=timestendb_1122"; //"jdbc:odbc:timestendb_1122";
if(args.length >= 2){
driverName = args[0];
Url = args[1];
}
System.out.println("driverName=" + driverName);
System.out.println("Url=" + Url);
System.out.println("classPath=" + System.getProperty("java.library.path"));
Class.forName(driverName).newInstance();
// Open a connection to TimesTen
Connection conn = DriverManager.getConnection(Url);
if(conn != null){
System.out.println("okay");
}
else{
System.out.println("fail");
}
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
odbc.ini config:

Resolve:
Check if exists:
$ldd /opt/TimesTen/tt1122/lib/libttJdbcCS.so

Check directory timesten client: $ ll /opt/TimesTen/tt1122/lib/libttclient.so
Go to to file to add share lib : sudo vi /etc/ld.so.conf.d/extension.conf -> Add: /opt/TimesTen/tt1122/lib
Check Again
java -Djava.library.path=/opt/TimesTen/tt1122/lib -jar test1.jar
Code Print:

Resolve:
export ODBCINI=/etc/odbc.ini (if you used odbc driver)
