Access database in Openshift

I deployed a project on OpenShift, I used a Cartridge to create a bank Mysql soon after the creation of the bank appear this information:

Mysql 5.5 database Added. Please make note of These credentials:

Root User: adminhtK8LZq Root Password: shKekKGKhHEH Database Name: Obolt

Connection URL: mysql://$OPENSHIFT_MYSQL_DB_HOST:$OPENSHIFT_MYSQL_DB_PORT/

You can Manage your new Mysql database by also embedding phpmyadmin. The phpmyadmin username and password will be the same as the Mysql credentials above.

But when I set up mine hibernate.cfg with this data the database is not created in the OpenShift.

Hibernate.cfg:

<!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://$OPENSHIFT_MYSQL_DB_HOST:$OPENSHIFT_MYSQL_DB_PORT/oraculo </property>
        <property name="connection.username">adminhtK8LZq</property>
        <property name="connection.password">shKekKGKhHEH</property>
        ...

I have to pass some value in place of this URL, I tried to pass the ip that appears in phpMyAdmin but it didn’t work.

Any reason for the pass given by Openshift and the pass on Hibernate.cfg to be different?

And why would Hibernate create the bank? It is only able to create or update the tables in one existing bank. To do so, use <property name="hibernate.hbm2dll.auto">create</property>, or update in place of create.

You can access your Cartridge via ssh and see if you can connect using these credentials?

I tried yes, but it’s still the same. I’m going to do one more test.

I just tried again and nothing, when access to URL that would query the database is not created. URL: http://sistemaoraculo-projetounimed.rhcloud.com/usuario/usuarios/consultar

I work with Openshift. I’ll explain to you what happens and how I usually work on this kind of thing.

Openshift has some variables to make your life easier. $OPENSHIFT_MYSQL_DB_HOST, $OPENSHIFT_MYSQL_DB_PORT and others are set there in openshift.

Below is an example of how I recover variables and connect using JDBC:

this.openShiftDbHost = System.getenv("OPENSHIFT_MYSQL_DB_HOST");
this.openShiftDbPort = System.getenv("OPENSHIFT_MYSQL_DB_PORT");
this.openShiftDbUser = System.getenv("OPENSHIFT_MYSQL_DB_USERNAME");
this.openShiftDbPassword = System.getenv("OPENSHIFT_MYSQL_DB_PASSWORD");
conexao =  DriverManager.getConnection("jdbc:mysql://"+this.openShiftDbHost+":"+this.openShiftDbPort+"/mydb?user="+this.openShiftDbUser+"&password="+this.openShiftDbPassword);

In the case of Hibernate I do the following coniguration:

<property name="url" value="jdbc:mysql://${OPENSHIFT_MYSQL_DB_HOST}:${OPENSHIFT_MYSQL_DB_PORT}/${OPENSHIFT_APP_NAME}" />
<property name="username" value="${OPENSHIFT_MYSQL_DB_USERNAME}" />
<property name="password" value="${OPENSHIFT_MYSQL_DB_PASSWORD}" />
