Introduction
The Hibernate access layer is used for database access and therefore requires configuration files. The access information such as accounts, passwords and JDBC URLs etc. are specified in hibernate configuration files. These files can be used at the time of installation of JOC Cockpit and JobScheduler Master or they can be created later on for individual jobs, e.g. the using of 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 Credential Store and add a reference to the credential store to your Hibernate configuration file.
- The following hibernate configuration files are available with JobScheduler Master and JOC Cockpit:
- JobScheduler Master:
- Run-time database: hibernate.cfg.xml
- Reporting database: reporting.hibernate.cfg.xml
- JOC Cockpit:
- JobScheduler run-time database: jobscheduler.hibernate.cfg.xml
Reporting database: reporting.hibernate.cfg.xml
- JobScheduler Master:
- Database accounts, passwords, and URLs are specified as plain text with the above 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 use the access data from the Credential Store it is required to first create the hibernate configuration file and then use the <entry key="databaseConfigurationMethod" value="withHibernateFile"/> at the time of installation and provide the path to the Hibernate configuration file.
- The Hibernate configuration file also supports the Credential Store.
FEATURE AVAILABILITY STARTING FROM RELEASE 1.13.3
FEATURE AVAILABILITY STARTING FROM RELEASE 1.12.12
Create a custom Hibernate file which accesses the Database accounts, password, and URL from the Credential Store.
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 Using a Credential Store for Jobs#Syntax article for a detailed description.
The syntax for Hibernate Configuration files
The Hibernate configuration file is introduced with different elements (properties) 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 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://<entry_path>@user?file=[path to *.kdbx file]</property>
<property name="hibernate.connection.password">cs://<entry_path>@password?file=[path to *.kdbx file]</property>
<property name="hibernate.connection.url">cs://<entry_path>@url?file=[path to *.kdbx file]</property>
The [path to *.kdbx file]
is a relative or absolute 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">[path to *.kdbx file]</property> → Stores the path to the credential store file
<property name="hibernate.sos.credential_store_key_file">[path to *.key file]</property> → Stores the path of the key file to open the credential store
<property name="hibernate.sos.credential_store_password">[some password]</property> → Stores the password of the credential store file
<property name="hibernate.sos.credential_store_entry_path">[/some/entry/path]</property> → specifies the directory structure and entry name in the credentials store file.
After adding the credential store reference to the Hibernate configuration file the database access data can be retrieved from the Credential Store by using the following property elements:
- <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 a password to access database credentials.
Explanations
- The Hibernate file makes use of a KeePass database (*.kdbx) for 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 of a hibernate file that uses the KeePass database (kdbx) with a key file (same name as of the kdbx but with extension .key) to access database credentials.
Explanations
- Hibernate file make use of KeePass database (kdbx) with Key File Authentication for accessing Database credentials
- cs://server/test/reporting/MySQL is the <entry_path> path where the MySQL database credential stores.
- file- File path where the KeePass database (kdbx)
Note: If the key file name and KeePass database (kdbx) file name are the same and are at the same location, for example, KeePass database name is kdbx-p-f.kdbx and the key file name is kdbx-p-f.key and both are on the same path i.e. config/cs then it will take the key default and it is not required to mention the path to the key file.
Downloads
- Download the attached archive hibernate_example.zip
Configuring attached example
- Unzip the archive to the live folder of JobScheduler installation
- Add the database configuration according to your environment in the KeePass file kdbx-p-f.kdbx.
- To access the KeePass file use kdbx-p-f.key as a key file.
- Make the changes for the Database (URL, Username, Password)
- The file hibernate-cs.syntax.full.cfg.xml includes the elements to access kdbx.
- The Databasejob includes the command (database query) to be executed
- Run the order hibernate_order from the JOC Cockpit
- The output of the command will be displayed
