代码示例：

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 配置：

[ODBC Data Sources]
timestendb_11221=TimesTen 11.2.2 Driver

[timestendb_1122]
TTC_SERVER=(Host || IP)
UID=Username
PWD=Password
TTC_SERVER_DSN=Cachedb01

错误：java.sql.SQLException：加载本机库/缺少方法时出现问题：/opt/TimesTen/tt1122/lib/libttJdbcCS.so：libttclient.so：无法打开共享对象文件：没有这样的文件或目录

解决：

检查是否存在：

$ldd /opt/TimesTen/tt1122/lib/libttJdbcCS.so

屏幕：

linux-vdso.so.1 =>  (0x00007fff039b4000)
    libttclient.so => not found
    libttco.so => not found
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f57d642e000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f57d6218000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f57d5e58000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f57d5c53000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f57d6876000)

检查目录时间客户端：$ ll /opt/TimesTen/tt1122/lib/libttclient.so

转到文件以添加共享库：sudo vi /etc/ld.so.conf.d/extension.conf -> 添加： /opt/TimesTen/tt1122/lib

再检查一遍

java -Djava.library.path=/opt/TimesTen/tt1122/lib -jar test1.jar

代码打印：

driverName=com.timesten.jdbc.TimesTenClientDriver
Url=jdbc:timesten:client:dsn=timestendb_1122
classPath=/opt/TimesTen/tt1122/lib
java.sql.SQLException: [TimesTen][TimesTen 11.2.2.5.0 CLIENT]Cannot find the requested DSN (timestendb_1122) in ODBCINI, Unable to open /var/TimesTen/tt1122/sys.odbc.ini. Permission denied

解决：

  1. export ODBCINI=/etc/odbc.ini（如果您使用 odbc 驱动程序）
  2. export ODBCINI=/var/TimesTen/tt1122/sys.odbc.ini（如果使用 Timesten 驱动程序）

可以为用户添加 bash 文件：

nano /home/nhatvd/.bashrc 
export ODBCINI=/etc/odbc.ini

$ ldd /opt/TimesTen/tt1122/lib/libttJdbcCS.so

    linux-vdso.so.1 =>  (0x00007fff429fe000)
    libttclient.so => /opt/TimesTen/tt1122/lib/libttclient.so (0x00007fd7977ee000)
    libttco.so => /opt/TimesTen/tt1122/lib/libttco.so (0x00007fd797520000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fd797223000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007fd79700d000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd796c4d000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fd796a48000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007fd796748000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fd79652b000)
    libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007fd796310000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fd797b12000)

结果：

$ java -Djava.library.path=/opt/TimesTen/tt1122/lib -jar test1.jar

代码打印：

driverName=com.timesten.jdbc.TimesTenClientDriver
Url=jdbc:timesten:client:dsn=timestendb_1122
classPath=/opt/TimesTen/tt1122/lib

好的

完毕。
