Issue encountered when Login as sysdba role using Thin Oracle JDBC Driver

Question

Hello all,
we are now considering to use Thin oracle JDBC driver to create database in our project, but we met one issue when we tried to connect to oracle as sysdba role using Thin driver, and it throws java.sql.SQLException: Io Exception: SO Exception was generated, I have found some tips on oracle jdbc website and it says :
How do I connect as SYSDBA or SYSOPER?
The only way to do this is to use the Properties object when connecting, rather than specifying the username and password as strings. Put the username into the "user" property, and the password into the "password" property. Then, put the mode into the "internal_logon" property. Something like the following:
Properties props = new Properties();
props.put("user", "scott");
props.put("password", "tiger");
props.put("internal_logon", "sysoper");
Connection conn = DriverManager.getConnection (url, props);
When connecting as SYSDBA or SYSOPER using the Thin driver, the RDBMS must be configured to use a password file. See "Creating and Maintaining a Password File" in the "Oracle Database Administrator's Guide".
So, i did execute orapwd command to create a password file and also set remote_login_passwordfile=execlusive in my initxxx.ora initial parameter file, however, when i tried to connect, it failed.
private static void createEmsdbDatabase(){
String url = "jdbc:oracle:thin:@localhost:1521:";
StringBuffer sqlStatement = new StringBuffer();
sqlStatement.append("create database xxx");
sqlStatement.append("maxdatafiles 254 ");
sqlStatement.append("maxinstances 8 ");
sqlStatement.append("maxlogfiles 32 ");
sqlStatement.append("character set UTF8 ");
sqlStatement.append("national character set UTF8 ");
sqlStatement.append("DATAFILE 'c:\\oracle\\xxx\\system01.dbf' SIZE 18M REUSE ");
sqlStatement.append("logfile 'c:\\oracle\\xxx\\redo01.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo02.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo03.log' SIZE 2M REUSE ");
try {
DriverManager.registerDriver(new OracleDriver());
Properties props = new Properties();
props.put("user", "sys");
props.put("password", "password");
props.put("database","xxx");
props.put("internal_logon", "sysdba");
Connection conn = DriverManager.getConnection(url, props);
Statement statement = conn.createStatement();
statement.executeUpdate(sqlStatement.toString());
statement.close();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
But what made me puzzled a lot is if i use OCI driver, it did work great, why??? guys, anybody knows, please give me some tips, thanks in advance.

Answer 1

clarify my question in detail:
Step 1 : create password file using orapwd command
Step 2 : create database instance using oradim command
Step 3 : login using sys as sysdba to startup database, e.g startup nomount pfile='...\initxxx.ora'
Step 4 : create database.
java code showing below:
private static void createEmsdbDatabase(){
String url = "jdbc:oracle:thin:@localhost:1521:";
StringBuffer sqlStatement = new StringBuffer();
sqlStatement.append("create database xxx ");
sqlStatement.append("maxdatafiles 254 ");
sqlStatement.append("maxinstances 8 ");
sqlStatement.append("maxlogfiles 32 ");
sqlStatement.append("character set UTF8 ");
sqlStatement.append("national character set UTF8 ");
sqlStatement.append("DATAFILE 'c:\\oracle\\xxx\\system01.dbf' SIZE 18M REUSE ");
sqlStatement.append("logfile 'c:\\oracle\\xxx\\redo01.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo02.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo03.log' SIZE 2M REUSE ");
try {
DriverManager.registerDriver(new OracleDriver());
Properties props = new Properties();
props.put("user", "sys");
props.put("password", "password");
props.put("database","xxx");
props.put("internal_logon", "sysdba");
Connection conn = DriverManager.getConnection(url, props);
Statement statement = conn.createStatement();
statement.executeUpdate(sqlStatement.toString());
statement.close();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
issue was met here, when i tried to login as sysdba using sys, and in my java code, i use Thin driver, it then thrus exception, but when OCI driver is used, it works great, i don't know why.
that is, when i use "jdbc:oracle:oci8:@" as database URL and then properties.put("database","xxx"), it works great. but, when i use "jdbc:oracle:thin:@localhost:1521:" as database URL and then properties.put("database","xxx"), it failed. hopefully, i have clarified my question clearly. thanks.
