I am using Hibernate + Java + Jersey + MYSql and it's working fine on local machine. However I am unable to create a connection to MySql on Google Cloud.
I think MYSql configuration and instance creation is fine on Google Cloud, but I am unable to pass all configuration through hibernate properties. See here what Google's sample code:
// The configuration object specifies behaviors for the connection pool.
HikariConfig config = new HikariConfig();
// Configure which instance and what database user to connect with.
config.setJdbcUrl(String.format("jdbc:mysql:///%s", DB_NAME));
config.setUsername(DB_USER); // e.g. "root", "postgres"
config.setPassword(DB_PASS); // e.g. "my-password"
// For Java users, the Cloud SQL JDBC Socket Factory can provide authenticated connections.
// See https://github.com/GoogleCloudPlatform/cloud-sql-jdbc-socket-factory for details.
config.addDataSourceProperty("socketFactory", "com.google.cloud.sql.mysql.SocketFactory");
config.addDataSourceProperty("cloudSqlInstance", CLOUD_SQL_CONNECTION_NAME);
config.addDataSourceProperty("useSSL", "false");
// ... Specify additional connection properties here.
// ...
// Initialize the connection pool using the configuration object.
DataSource pool = new HikariDataSource(config);
Now I dont know how to pass cloudSqlInstance and socketFactory in Hibernate. Here what I tried to pass these parameters but it's not working:
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hibernate.connection.url = jdbc:mysql://google/pashumandi_db?cloudSqlInstance=pashuserver:asia-south1:mysql-instance&socketFactory=com.google.cloud.sql.mysql.SocketFactory
hibernate.connection.username = abc_user
hibernate.connection.password = 12345678
hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
Could you please let me know what is correct hibernate configuration to connect with MySql on Google Cloud? Thanks.
For Google Cloud you can select your DB instance and then under “CONNECTIONS” you can select to allow connections from Public IP addresses and then add your machine’s IP address to the list of addresses authorizes to make a connection. From there all you need to do is use the public IP address of your DB instance in the URL.
Find the INSTANCE_CONNECTION_NAME for the instance on the Instance details page on Google Cloud Console. It uses the format PROJECT_ID:REGION:INSTANCE_ID, and is used to identify the Cloud SQL instance you are connecting to.
To enable a local TCP port, add the following to your project's app.yaml file:
runtime: java
env: flex
beta_settings:
cloud_sql_instances: <INSTANCE_CONNECTION_NAME>=tcp:<PORT>
Then here is my hibernate.properties file:
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hibernate.connection.url = jdbc:mysql://172.17.0.1:PORT_NUMBER_IN_YAML_FILE
hibernate.connection.username = DB_USERNAME
hibernate.connection.password = DB_PASSWORD
hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
hibernate.default_schema = DATABASE_NAME
hibernate.show_sql=true
hibernate.hbm2ddl.auto=create

What authorities are required to create a connection by AS400JDBCDriver.connect() without supplying username/password.
Trying to create a JDBC connection by using jt400 APIs without supplying the username/password as:
AS400 system = new AS400();
AS400JDBCDriver driver = new AS400JDBCDriver();
Properties prop = new Properties();
prop.setProperty("translate binary", "true");
prop.setProperty("prompt", "false");
prop.setProperty("naming", "sql");
String schema = "MySchema";
connection = driver.connect(system, prop, xref);
Details: If running on IBM i, the target is the local system. This has the same effect as using localhost for the system name, *CURRENT for the user ID, and *CURRENT for the password.
com.ibm.as400.access.AS400
I am getting the exception:
java.sql.SQLException: The application server rejected the connection. (User ID is disabled
So my question is:
What authorities are required to create a connection by
AS400JDBCDriver.connect() without supplying username/password??
I've got an Azure SQL Server database that I'm connecting to via JDBC, but want to connect instead to my SQL Server "localhost". In SSMS, I connect to localhost without needing a password. So, do I still need to enter a password in Java?
I have a code like this :
String connectionUrl =
"jdbc:sqlserver://etcetc.database.windows.net:1433;"
+ "database=med;"
+ "user=windersan#salemimed;"
+ "password=********;"
+ "encrypt=true;"
+ "trustServerCertificate=false;"
// + "hostNameInCertificate=*.database.windows.net;"
+ "loginTimeout=30;";
How do I change this to connect instead to localhost?
Just replace the etcetc.database.windows.net by localhost and replace the port number 1433 by the number that you are using.
I have used SQLServerDataSource class to make the work easier. You can also create a string URL and set it in the DriverManger.getConnection().
Try with this code :
SQLServerDataSource dataSource = new SQLServerDataSource();
dataSource.setUser("windersan#salemimed");
dataSource.setPassword("********");
dataSource.setServerName("localhost");
// set the port number of your system below.
dataSource.setPortNumber(1433);
dataSource.setDatabaseName("med");
dataSource.setEncrypt(true);
dataSource.setHostNameInCertificate("*.database.windows.net");
dataSource.setTrustServerCertificate(false);
Connection connection = dataSource.getConnection();
Please refer to this links down below for more info.
Microsoft Docs - ISQLServerDataSource Interface - This contains the list of methods that you can use to set the various properties in the datasource.
Microsoft Docs - How to work with the connection - This contains examples of the possible ways to connect to a SQL Server database.
the first line of your concatenated string contains the url etcetc.database.windows.net:1433 this is the location of the database server, and the bit you should change.
Also, it might be worth doing a google search on connecting to SqlServer with JDBC to see if there are any examples out there.
I am facing an issue regarding MongoDB multi-tenancy. I have two different mongoDB databases (db1 and db2). These both have different credentials.
db1 credentials:
userName: admin
password: passwd
db2 credentials:
userName: admin1
password: passwd1
I need to switch from one database to other at run-time. I have autowired mongoTemplate with db1 credentials, but now I am unable to update the template with db2 credentials. Is this possible? If yes, how? If not, please tell me any other way to switch the databases at run-time with different credentials.
Note that, I am aware of "SimpleMongoDbFactory". One can extend "SimpleMongoDbFactory" and can override "getDb" method and pass the required dbName in super.getDb("dbName") for multitenancy. But, this does not work with two databases with different credentials.
What if you create a MongoCredential for each DB and pass them to a MongoClient that you pass to your SimpleMongoDbFactory
MongoCredential credential1 = MongoCredential.createCredential("admin", db1, "password");
MongoCredential credential2 = MongoCredential.createCredential("admin1", db2, "password1");
MongoClient mongoClient = new MongoClient(new ServerAddress(), Arrays.asList(credential1, credential2));
Create independent MongoTemplate instances each one with it's own credentials and select the appropriate in runtime.
Every connection is established using the credentials so if you change them on an existing connection you are essentially destroying the connection and creating a new one and would not be taking advantage of pooling.
I have an application that needs to use connection pool when connection to the database. Problem is, the application is designed to configure and change the connection settings on the fly. I have written the following code that will allow me to dynamically create the data source and then use that to open the connections to the database. However, this code was written for the DataDirect driver and I have used it to connect to Oracle and MS SQL. Unfortunately, the DataDirect Mysql driver will only connect to the commercial version of mysql, not the free version. So now I am attempting to accomplish the same task with connect/j from mysql. I cannot find how to set the connection properties found in a external (static) datasource definition via method calls like for the DD driver. Any help would be appreciated.
BaseDataSource bds = (BaseDataSource)ds;
// Populate the DataSource
bds.setDescription("Driver Data Source");
bds.setServerName(connectUrl);
bds.setUser(userName);
bds.setPassword(password);
if ( spyAttr.length() > 0 ) bds.setSpyAttributes(spyAttr);
// Create the PooledConnection DataSource. Pass the data source created above
// to the PooledConnection DataSource
pds = new PooledConnectionDataSource();
pds.setDescription("Pooled Data Source");
pds.setDataSourceName("myDataSource", bds);
pds.setPoolName("myPool");
pds.setInitialPoolSize(nPoolSize);
pds.setMinPoolSize(minPoolSize);
pds.setMaxPoolSize(maxPoolSize);
pds.setPropertyCycle(propCycle);
pds.setMaxIdleTime(maxIdleTime);
pds.setTracing(tracing);
// Get connection
pds.getConnection();
Apparently the MySQL Connector/J driver doesn't allow those parameters to be passed in with method calls so you will have to pass them in as parameters in the URL (jdbc:mysql://localhost/test?user=foo&password=bar).
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.
