Introduction

The Hibernate configuration files are the Database configuration files. The database information like database users, passwords, and jdbc URLs etc are specified in the hibernate configuration files. These files configuration access layer is used for database access and therefore requires configuration files for credentials. The access information such as accounts, passwords and JDBC URLs etc. are specified in Hibernate configuration files. Such files can be used at the time of installation or of JOC Cockpit and JobScheduler Master and they can be created later on for the using of the ManagedDatabaseJobJSAdapterClass job.The Hibernate configuration files used by the installation are:individual jobs, e.g. the for use with the Job JobSchedulerManagedDatabaseJobSOSHibernate.

Generally it is preferable not to use passwords to access a database but to use Integrated Security, Oracle Wallet etc. However, should there be a need to specify passwords then instead of using a plain text password in a configuration file you can add your password to a KeePass Credential Store and add a reference for the Credential Store to your Hibernate configuration file. 

• The following hibernate configuration files are available with JobScheduler Master and JOC Cockpit:
  • JobScheduler Master:
    • Run
    JobScheduler run
    • -time database: hibernate.cfg.xml
    for JobScheduler and jobscheduler
    • Reporting database: reporting.hibernate.cfg.xml 
  • for JOC Cockpit:
    • JobScheduler run-time database: jobscheduler.hibernate.cfg.xml

    • Reporting database: reporting.hibernate.cfg.xml 

• Database accounts, passwords, and URLs are specified as plain text with the above hibernate Hibernate configuration files when they are provided at the time of installation using the option <entry key="databaseConfigurationMethod" value="withoutHibernateFile"/>. To make the hibernate configuration file to use the database information from the access data from a Credential Store it is required to first create the hibernate configuration files file and then to use the <entry key="databaseConfigurationMethod" value="withHibernateFile"/> at the time of installation and to provide the path to the Hibernate configurations file.configuration file e.g. with a value like this: <entry key="reporting.hibernateConfFile" value="jobscheduler.hibernate.cfg.xml"/>.
• Support for use of a Credential Store with Hibernate configuration filesThe Hibernate configuration file also supports the Credential Store.

Syntax for Hibernate Configuration Files

The Hibernate

Parameter String to retrieve the data from Credential Store

The SOSKeePassDatabase the class uses a parameter string that holds a URI and a number of query parameters:

URI

cs://<entry_path>@<property_name> - required 

• The URI based syntax includes the protocol cs:// 
• followed by the <entry_path> that specifies the directory structure and entry name in the credentials store file.
• followed by the @ character

• followed by the <property_name> that should be retrieved:

  • frequently-used properties include credential store field names such as title, user, password, attachment Custom field names are supported. 

Query Parameters

• file - required 
  the path to the credential store database file. This file can be stored anywhere in the file system.

• password - optional 
  the password for the credential store database file. 
  It is recommended not to use this parameter and instead to use a key_file to access the credential store.

• key_file - optional, default: <credential_store_database_filename_without_extension>.key 

Refer to the Knowledgebase article Using a Credential Store for Jobs#Syntax for a detailed description.

The syntax for Hibernate Configuration files

The hibernate configuration file is introduced with different elements (property optionsproperties) which that can be used to retrieve the information from a Credential Store. It provides two types of syntax: 

Full Syntax

The Full syntax is used when the complete URI is to be used specified with each property element of the Hibernate configuration file. The following syntax can be used to retrieve the information from Credential Store: 

• <property name="hibernate.connection.username">cs://secret/database/<entry_path>@userreporting@user?file=<path to database kdbx file><./config/live/hibernate_example/secret.kdbx</property> 
• <property name="hibernate.connection.password">cs>cs://secret/database/<entry_path>@passwordreporting@password?file=<path to database kdbx file>./config/live/hibernate_example/secret.kdbx</property>

• <property name="hibernate.connection.url">cs>cs://secret/database/<entry_path>reporting@url?file=<path to database kdbx file>./config/live/hibernate_example/secret.kdbx</property>

Explanations:

• The secret/database/reporting value is an example for a path to an entry in the KeePass database that holds the credentials.
• The ./config/live/hibernate_example/secret.kdbx value is an example for a relative path to the KeePass database that holds the Credential Store.

Short Syntax

The Short syntax is used when the credential store items are to be used in the hibernate configuration to provide the details about the credential store:

• <property name="hibernate.sos.credential_store_file">some/path/database.kdbx<>./config/live/hibernate_example/secret.kdbx</property> → Stores stores the path to the credential store Credential Store file
• <property name="hibernate.sos.credential_store_key_file">some/path/database.key<>./config/live/hibernate_example/secret.key</property> → Stores stores the path of the key file to open the credential storefor the Credential Store
• <property name="hibernate.sos.credential_store_password">some password<>secret</property> → Stores stores the password of the credential store Credential Store file
• <property name="hibernate.sos.credential_store_entry_path">/somesecret/entrydatabase/path<reporting</property> → specifies the directory structure  → specifies the folder hierarchy and entry name in the credentials store Credentials Store file.

After adding the credential store items in the hibernate the Credential Store reference to the Hibernate configuration file as above the database information credentials can be retrieved from the credential store Credential Store by using the following property elementelements: 

• <property name="hibernate.connection.username">cs://@user</property> 
• <property name="hibernate.connection.password">cs://@password</property> 
• <property name="hibernate.connection.url">cs://@url</property>     

Example of a hibernate file that uses the KeePass database (kdbx) with Password to access database credentials.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.url"><![CDATA[cs://server/test/reporting/MySQL@url?file=config/cs/kdbx-p-f.kdbx&password=test]]></property>
<property name="hibernate.connection.username"><![CDATA[cs://server/prod/reporting/MySQL@username?file=config/cs/kdbx-p-f.kdbx&password=test]]></property>
<property name="hibernate.connection.password"><![CDATA[cs://server/test/reporting/MySQL@password?file=config/cs/kdbx-p-f.kdbx&password=test]]></property>
<property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property>

<property name="hibernate.show_sql">false</property>
<property name="hibernate.connection.autocommit">false</property>
<property name="hibernate.format_sql">true</property>
<property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
</session-factory>
</hibernate-configuration>

Explanations

• Hibernate file make use of KeePass database (kdbx) for accessing Database credentials
• cs://server/test/reporting/MySQL is the <entry_path> path where the MySQL database credential stores.
• file - File path of the KeePass database (kdbx).
• password- Password for accessing the KeePass database (kdbx)

Example

Hibernate Configuration File

Example of a Hibernate configuration file for MySQL that makes use of a KeePass database that is secured Example of a hibernate file that uses the KeePass database (kdbx) with a key file (same name as of the kdbx KeePass database but with extension .key) to access database credentials.:

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<hibernate-configuration> 
  <session-factory> factory>
    <property name="hibernate.connection.url"><![CDATA[cs://serversecret/testdatabase/reporting/MySQL@urlreporting@url?file=./config/cs/kdbx-p-flive/hibernate_example/secret.kdbx]]></property>
    <property name="hibernate.connection.username"><![CDATA[cs://serversecret/proddatabase/reporting/MySQL@usernamereporting@user?file=./config/cs/kdbx-p-flive/hibernate_example/secret.kdbx]]></property>
    <property name="hibernate.connection.password"><![CDATA[cs://serversecret/testdatabase/reporting/MySQL@passwordreporting@password?file=./config/cs/kdbx-p-flive/hibernate_example/secret.kdbx]]></property>
    <property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property> 
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> 
    <property name="hibernate.show_sql">false</property> 
    <property name="hibernate.connection.autocommit">false</property>  
    <property name="hibernate.format_sql">true</property> 
    <property name="hibernate.temp.use_jdbc_metadata_defaults">false</property> 
  </session-factory> 
</hibernate-configuration> 

Explanations

• The Hibernate file make makes use of the KeePass database (kdbx) secret.kdbx located in the ./config/live/hibernate_example folder of JobScheduler Master with Key File Authentication for accessing Database credentials.
• cs://serversecret/testdatabase/reporting/MySQL is the <entry_path> path where the MySQL database credential stores.
• file- File path where the KeePass database (kdbx)

...

• is the path to the entry in the KeePass database where the database credentials are stored.

Notes:

• If the base names of the KeePass database (secret.kdbx) and of the key file (secret.key) are the same and if the files are stored in the same location then it is not required to specify the key file as it will be automatically looked up.
• It is possible to secure a KeePass database with a password, however, this makes no sense in a context that avoids directly readable passwords. A key file can better be secured by OS permissions that rule access to the key file.

...

Download

• Download the attached archive hibernate_example.zip

...

Using the Example

• Unzip the archive to the ./config/live folder of JobScheduler installation Master. This will create a sub-folder hibernate_example.
• Add the database configuration according to your environment in to the KeePass file kdbx-p-f.kdbx. To access the KeePass file use kdbx-p-f.key as a key filedatabase secret.kdbx.. Access to the KeePass database is secured with the key file secret.key.
• Make the changes for the Database database access (URL, Usernameusername, Passwordpassword).
• The file The hibernate-cs.syntax.full.cfg.xml includes xml file includes the elements to access kdbxthe KeePass database.
• The Databasejob includes the command ( query_database job includes the database query ) to be executed: select count(*) as number_of_hits from SCHEDULER_HISTORY;
• The display_results job echos the value of the result parameter number_of_hits to the log..
• Run the order hibernate_order from the JOC Cockpit.
• The output of the command database query will be displayed with the log.
