Reading the documentation on PostgreSQL documentation here I read the following:
As well, connections requested for users other than the default configured user are not pooled.
I couldn't find any more information on this. Who is the default configured user? Is it
the user I logged in to the db with?
So in the following example:
Jdbc3PoolingDataSource source = new Jdbc3PoolingDataSource();
source.setDataSourceName("A Data Source");
source.setServerName("localhost");
source.setDatabaseName("test");
source.setUser("testuser");
the default configured user is testuser?
The default user is the one you set on the DataSource itself, however a DataSource has more than one method to obtain a connection:
getConnection()
getConnection(String username, String password)
The first method uses the (default) user configured on the DataSource. Based on the quoted documentation for the implementation you use, this method will provide a connection from the connection pool.
The second method takes a user name and password, and as indicated by the documentation you quoted that connection will not be pooled (except maybe if the username and password provided matches the default user of the DataSource).

I have been trying to connect to Teradata
Class.forName("com.teradata.jdbc.TeraDriver");
String connectionString = "jdbc:teradata://xxx.xxxxxx.com/database=xxxxxx, tmode=ANSI, charset=UTF8";
String user = "Rocket512";
String password = "aui8mn5";
Connection conn = DriverManager.getConnection(connectionString, user, password);
Got the following
Exception in thread "main" com.teradata.jdbc.jdbc_4.util.JDBCException: [Teradata Database]
[TeraJDBC 14.10.00.17] [Error 8017] [SQLState 28000] The UserId, Password or Account is invalid.
at com.teradata.jdbc.jdbc_4.util.ErrorFactory.makeDatabaseSQLException(ErrorFactory.java:300)
at com.teradata.jdbc.jdbc.GenericLogonController.run(GenericLogonController.java:666)
at com.teradata.jdbc.jdbc_4.TDSession.<init>(TDSession.java:216)
I know that the host is specified correctly since i did not get UnknownHost Exception.
Also I have double checked my userid and password are correct.
I ran query suggested by #beni23 (thank you)
select *
from dbc.logonoff
where logdate >= date '2013-10-31'
Here is the result that I got
What is Bad Password? I used SQL Assistant with this very password and it works great. Why cannot i connect with Java?
LDAP Authentication failures will not be captured in DBC.LogOnOff as a Bad Password event because the authentication doesn't take place on the database.
Typically the error message you are receiving, The UserId, Password or Account is invalid., is indicative of the user account being locked on the database.
SELECT U.UserName
, U.ProfileName
, U.DefaultAccount
, COALESCE(P.MAXLOGONATTEMPTS, S.MAXLOGONATTEMPTS) AS MaxLogonAttempts_
, U.LockedCount
, U.LockedDate
FROM dbc.UsersV U
LEFT JOIN
dbc.ProfileInfoV P
ON P.ProfileName = U.ProfileName
CROSS JOIN
dbc.SecurityDefaults S
WHERE UserName = 'Rocket512';
If LockedCount is not 0 than a failed logon attempt has occurred since the last successful logon to the database.
If LockedDate is not NULL it represents the date which the account was last locked.
MaxLogonAttempts_ will tell you how many times you can attempt to logon using database authentication (TD2) before the account is locked.
A couple of things I would suggest:
Remove whitespace between the parameters of connectString
Put the User and Password parameters in the connectString
Using original code above modify the connectString to add: ,ACCOUNT=$AMRWRW&DrT&r which should match what is returned by the query in my response above (I have added DefaultAccount).
EDIT: 11/12/13
May I suggest you download Teradata Studio Express and attempt to make a connection to the same Teradata system using JDBC much like you are here in your code. This may help shed light on the parameters you need to specify in your connection string in order to make the connection successful. You should be able to setup your connection parameters in Teradata Studio Express the same as you have here in your code and see if it works.
Using LDAP as the logon mechanism for a user that has not been granted the explicit right to logon with a NULL password has resulted in the error message `The UserId, Password or Account is invalid.'. I received this the other day using a privileged account without changing my logon mechanism from LDAP to TD2.
What does the following SQL return?
SELECT *
FROM DBC.LogonRulesV
WHERE UserName = 'Rocket512';
It may not return anything, which is okay. This simply means you ability to logon with that userid from any host on the system has not been explicitly granted or revoked.
EDIT: 05/22/18
The “Bad Password” event for an externally authenticated user may will appear in the event log when the provided password and the what is stored on the directory server do not match. In certain scenarios you can verify this by using ldapsearch from the PDN to submit an inquiry directly to the LDAP directory. You can find more details about using this command in the Security Administration manual. I’ve discovered this trying to triage a problem with a subset of user accounts that fail to authenticate to the directory. I felt it would be appropriate to update this answer with more details as my lead in statement at the top is not 100% accurate.
The following might not give you a solution, but might point you in the right direction. I think you'll want to check the dbc.logonoff table in teradata through a console to make sure that your user is not locked or get an idea whether your driver is hitting teradata.
select *
from dbc.logonoff
where logdate >= date '2013-10-31'
Reading this article Troubleshooting Security: The UserId, Password or Account is invalid. we can see the typical reason of this error.
Cause: LOGMECH=LDAP is specified, and the username/password credentials
are redundantly provided in the both LOGDATA and as separate
connection parameters.
Solution: Identify LDAP users via LOGDATA, or
via separate username/password parameters, but not both
simultaneously.
So, you should check this case. May be you can get connection without user/password
Perhaps you might have more luck with:
String driver = "com.teradata.jdbc.TeraDriver";
String conUrl="jdbc:teradata://xxx.xxxxxx.com/database=xxxxxx,USER=Rocket512,PASSWORD=aui8mn5,tmode=ANSI,charset=UTF8";
Class.forName(driver);
Connection dbConn = DriverManager.getConnection(conUrl);
If that doesn't work make sure to use the latest jdbc driver.
I had similar error and followed all the suggestions given in here. My account was not locked and I was able to connect to the DB with the same username and password, via SQL assistance editor.
The solution worked for me was adding following line in the connection string: LOGMECH=LDAP.
You need to know the logon mechanism for your Teradata, or you can reach out to your DBA team, as I did. So your connection string will look something like this:
String connurl="jdbc:teradata://xx/database=xx,USER=xx,PASSWORD=xx,tmode=ANSI,charset=UTF8,LOGMECH=LDAP";
I am trying to use a datasource to get connection to Oracle database.
I am setting the OracleConnectionCacheImpl object with properties like driverType, networkProtocol, user, password, databaseName, serverName, portNumber.
setUrl cannot be used.
What should I do to get a connection like in the case, if the following url is used ?
jdbc:oracle:thin:#(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service_name)))
I hope I made some sense in what I told.
For RAC, you need to set the URL.
In my experience, if you do not set the URL explicitly, it will not work in this case.
I am unable to comment, hence posting a new reply.
I have the following code:
Hashtable env1 = new Hashtable();
env1.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
log.info("Executed step 1");
env1.put(javax.naming.Context.PROVIDER_URL, "iiop://myhost.com:9301");
log.info("Executed step 2");
Context ctx = new InitialContext(env1);
DataSource ds = (DataSource)ctx.lookup("jdbc/mydatasource");
log.info("Excecuted lookup ="+ds);
conn = ds.getConnection();
I have the previous code in an standalone application that is connecting to WAS 6.1.0.3 in order to retrieve a connection from the datasource. The code is very straighforward, and I have seen the same code working in a different environment, but in this case when I call getConnection I get an exception. The datasource is WAS has the proper authentication alias set and when the connection is tested it works OK from the WAS side, but the previous code won't work.
If I change this line: conn = ds.getConnection();
to this: conn = ds.getConnection("username","password");
Then the code will work! But that's not what I want since the connections in the datasource should already have the credentials set. I was initially thinking this was a Sybase problem, but it's also happening with Oracle, so would rather say I have a problem with WAS.
If you are curious about the exceptions, for Sybase I get:
java.sql.SQLException: JZ004: User name property missing in DriverManager.getConnection(..., Properties).DSRA0010E: SQL State = JZ004, Error Code = 0

In both cases I won't the exception if I pass the credentials to the getConnection method
Thanks for your advice.
Short answer: external clients don't get to use the authentication alias data
Longer Answer:
From the WAS J2C connection factory documentation:
The alias that you configure for component-managed authentication does not apply to all clients that must access the secured resource. External Java clients with Java Naming and Directory Interface (JNDI) access can look up a Java 2 Connector (J2C) resource such as a data source or Java Message Service (JMS) queue. However, they are not permitted to take advantage of the component-managed authentication alias defined on the resource. This alias is the default value that is used when the getConnection() method does not specify any authentication data, like user and password, or a value for ConnectionSpec. If an external client needs to get a connection, it must assume responsibility for the authentication by passing it through arguments on the getConnection() call.
It's been a long time since I've done anything with WebSFEAR^H^H^H^Hphere, but it looks to me that you have a configuration problem. There was a special screen where you'd create credentials (user/pass) and later you'd apply those credentials to the created data source. It looks like that your configured data source hasn't got credentials applied.
Even after defining the user/password values as custom properties I found that the connections for Oracle weren't working. After many days, I just found that the development server is running an old WAS 6.1 version, the problem I'm having was fixed in WAS 6.1.0.5: PK32838: J2CA0046E WHEN USING USING CUSTOM PROP PASSWORD ON DATASOURECE
I tried my code in a different WAS server with an updated WAS fix pack level and... it worked without introducing a single change in the code or in the configuration. So the solution is to upgrade the WAS server.
Thanks.
I'm writing a desktop java app on that I want to connect to a MySQL database on a server. Here is the code to do that:
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
private static Connection getDBConnection() throws SQLException, InstantiationException, IllegalAccessException, ClassNotFoundException {
String username = "myUserName";
String password = "myPassWord";
String url = "jdbc:mysql://www.domainName.com:3306/databaseName";
Class.forName("com.mysql.jdbc.Driver");
System.out.println("Connecting to database...");
//hangs here
Connection conn = DriverManager.getConnection(url, username, password);
return conn;
}
When I run this, it hangs on the DriverManager.getConnection() call. Why does this happen? Is my URL malformed?
(I'm not getting any error messages, but the program doesn't respond as if in an infinite loop. I haven't waited longer than 90 seconds to see if the connection will ever be established.)
Also, what is the purpose of the Class.forName() call? How does it work?
I am almost entirely certain that the username and password are correct. (I just used userName and passWord as placeholders above.)
UPDATE: I fixed the port number, and now I get this error:
Cannot connect to database: java.sql.SQLException: Access denied
for user 'userName'#'r236059121.resnet.mySchool.edu' (using
password: YES)
Does this mean I need to configure settings on the database? Or does it mean that I've got the credentials wrong? (They work for PHP scripts deployed on the server that contains the database.)
SOLUTION: Added the host above to the Access Host list on cPanel.
Seems to me like your database is not reachable and you will probably get an error when the call runs into a timeout. Are you sure the hostname and port are right and reachable from your machine?
You don't need the newInstance() at the end of Class.forName(). Class.forName() triggers the classloader to load that class, which in turn triggers some internal registration code in the driver which makes the driver available.
I think the line should just be
Class.forName("com.mysql.jdbc.Driver");
(close the .newInstance() bit)
That causes the driver to register itself with the driver manager and allows the driver manager to pick a driver for the database url.
I think the hang is caused by a DNS problem, or some other reason why your db cannot be reached. By default, the MySQL JDBC driver does not time out for a connection. See http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html and look for connectTimeout.
In your code, you have
String url = "jdbc:mysql://www.domainName.com:portNumber/databaseName";
I take it that you used a real port there? By default, it should be 3306. You can test with the test database which is present in virtually all mysql instances:
String url = "jdbc:mysql://www.domainName.com:3306/test";
You also wrote:
String username = "myUserName";
String password = "myPassWord";
Obviously you should use real credentials here too. Ask your dba what they are. If you're the DBA then...well you should probably read up on MySQl administration :) Seriously when you installed MySQL you were probably promted for a password for the root user. Use those (in the obvious way)
In real code you should probably not hang when the db is not there. So I advise adding a connectTimeout option like so:
String url = "jdbc:mysql://www.domainName.com:3306/test?connectTimeout=3000";
(connectTimeout is in milliseconds, so this would time out after 3 seconds)
Rosarch - You are not able to connect to your DB since its unreachable.
It'll timeout after a while.
Try telnetting -
telnet <IP-OF-domainName.com> <PortNumber>
You'll mostly see that it shows timeout.
Solutions -
1.) If you are behind a firewall, you need to punch a hole to allow access
2.) If you are behind a proxy, need to configure it to allow access
When my application connects to an Oracle database I want to be able to see by looking at the active sessions in the database that it is connected. Currently it identifies itself as "JDBC Thin Client" because that's the driver that I'm using, but other Java based applications that I have are somehow able to set this value to something more meaningful, like "SQL Developer". I thought it was a property of the Connection or the OracleDataSource, but I've not managed to find one that does the trick. Is this possible? In case it matters, I'm using Java 1.5, with Oracle 10g and the 10g thin driver.
java.util.Properties props = new java.util.Properties();
props.setProperty("password","mypassword");
props.setProperty("user","myusername");
props.put("v$session.osuser", System.getProperty("user.name").toString());
props.put("v$session.machine", InetAddress.getLocalHost().getCanonicalHostName());
props.put("v$session.program", "My Program Name");
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
Connection conn=
DriverManager.getConnection("jdbc:oracle:thin:#myhostname:1521:mysid", props);
SQL>select username,osuser,program,machine
from v$session
where username = 'ROB';
USERNAME OSUSER PROGRAM MACHINE
--------- ----------- ------------------ -----------
ROB rmerkw My Program Name machine
At application level you can use the following methods to set client_info, module and action in v$session:
dbms_application_info.set_client_info
dbms_application_info.set_module
dbms_application_info.set_action
There is also an Oracle function:
dbms_application_info.set_client_info('Client Info');
which sets the ClientInfo column in v$session.
This might be useful if you only have access to the Connection rather than the underlying DataSource or DriverManager.
Since oracle jdbc 12.1 you can set some client-info values via jdbc api, i.e. you can do
connection.setClientInfo("OCSID.CLIENTID", "MyClientId");
for properties OCSID...
ACTION, CLIENTID, ECID, MODULE, SEQUENCE_NUMBER and DBOP
See https://docs.oracle.com/database/121/JJDBC/jdbcvers.htm#JJDBC29006
Setting PROGRAM doesn't work this way, you can do that as described in the accepted answer or somewhat easier by setting the System property "oracle.jdbc.v$session.program".
You need to define the connection property v$session.program in your data source, in such a way that that property will be added to each connection. How you do that depends on your data source implementation. The value you set the property to will appear in oracle's active session table.
Starting with 12.1 the setEndToEndMetrics is deprecated, you may use setClientInfo
see the documentation for 12.2 here
Here a snippet of the usage
// "conn" is an instance of java.sql.Connection:
conn.setClientInfo("OCSID.CLIENTID", "clientID");
conn.setClientInfo("OCSID.MODULE", "myModule");
conn.setClientInfo("OCSID.ACTION", "myAction");
You may see the setting in V$SESSION with this query of the relevant session
select MODULE, ACTION, CLIENT_IDENTIFIER from v$session where ...
but only after a next statement is executed with this connection. The call of setClientInfo triggers no extra roundtrip this information is passed whit the next call.
Note also that you must use the Oracle (unwrapped) conenction - Check this for reference.
