The JDBCStorageService is a database-level compatible replacement for the JPAStorageService and provides a Storage Service StorageService on top of an RDBMS.  It communicates directly with the database rather than using Hibernate ORM which has issues with reliability and the lack of provenance of its software artifacts.

It is possible to swap between the JPA and JDBC storage service (if running an older version of our software), and indeed to have different versions running on different nodes.

For a detailed guide on how to install plugins, see here. In summary, use the plugin command that ships with the IdP to install the plugin from either a local file pre-downloaded, from a URL, or by pluginId ^4.2

Installation

C:>\opt\shibboleth-idp\bin\plugin.bat -I net.shibboleth.plugin.storage.jdbc

or

$ /opt/shibboleth-idp/bin/plugin.sh -i http://shibboleth.net/downloads/identity-provider/plugins/pluginName/version/URL

Switching from JPAStorageService

If you are currently running with the JPAStorageService you can reconfigure to use the JDBCStorageService relatively easily

• Locate the configuration (search for the class name org.opensaml.storage.impl.JPAStorageService

• Remove the EntityManagerFactory bean, taking note of the dataSource property.

• Remove also the VendorAdapter bean if present.

• Change the StorageService bean

  • Replace class="org.opensaml.storage.impl.JPAStorageService" with parent="shibboleth.JDBCStorageService"

  • Remove the constructor parameter and instead add a pointer to the dataSource you noted above p:dataSource-ref="...."

At this stage you should be able to test the configuration.

Once it works you can change bean names appropriately and add any extra configuration as detailed below.

Database Preparation

If you are (preferred) by plugin ID.

Database Preparation

If not upgrading from a JPAStorageService configuration, then you need to:

• Create the database table for the plugin to use.

• Download the appropriate JDBC driver.

• (Optionally, but recommended) Download Select a Connection Pooling implementation. DBCP2, included with the IdP software, is suggested as it requires no additional software.

(If you are moving migrating from the JPAStorageService you do not need to make any changes to your database and you can use the same configuration for the DataSource as you did for the JPAStorageService. See more below.)

Creating the Database

Example Schemas are shown below.

Configuring and Using JDBC DataSources

Using JDBC requires defining a Spring bean representing the DataSource instance the IdP will create and inject into, among other places, this plugin’s StorageService definition. Note that a JDBC driver class is not the same as a DataSource. Generally a database driver will provide one or more DataSource implementation classes to choose from and this is the class you will need to create via a Spring bean to inject into other objects.

A data source will typically look like this (with most of the settings depending on the particular driver:

<bean id="my.DataSource" class="..."
  p:url="jdbc:database:connectionprops" />

JDBC Driver

You need to locate, download and verify the JDBC driver for your database and place it in edit-webapp/WEB-INF/lib.After populating edit-webapp/WEB-INF/lib you should execute bin/build.sh or bin/build.bat as appropriate for your environment.

Connection Pooling

We recommend For higher loads, we generally assume the use of a DataSource that provides connection pooling. The Commons DBCP 2 library is included with the IdP and recommended can be used for this purpose without downloading additional libraries.

...

• Commons DBCP 2

• HikariCP

• BoneCP - Repository Marked Archived on Jun 3, 2024

Having located, downloaded and verified the connection pooling jar you should place it in As with the driver above, if you choose to use a third party pooling library not supplied with the software, you will need to add its jar(s) to edit-webapp/WEB-INF/lib.After populating edit-webapp/WEB-INF/lib you should execute bin/build.sh or bin/build.bat as appropriate for your environment

Configuration

You and rebuild the warfile.

Storage Service Configuration

Once a DataSource bean is in place, you need to add the definition of a bean derived inheriting from shibboleth.JDBCStorageService into an appropriate configuration file (usually global.xml). The options you can provide to the bear bean are detailed below.

...

In the example below use of Commons DBCP is demonstrated (class="org.apache.commons.dbcp.BasicDataSource", p:url="..." in the DataSource bean). When using other Connection Pool implementations change the class and properties appropriately , (e.g.:

...

Tomcat DBCP2: class="org.apache.tomcat.dbcp.dbcp2.BasicDataSource", p:url="..."

...

,

...

HikariCP: class="com.zaxxer.hikari.HikariDataSource"

...

p:jdbcUrl="...")

    <bean id="my.dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close" lazy-init="true"
       p:driverClassName="......"
       p:url="jdbc:hsqldb:mem:StorageService"
       p:username="shibboleth"
       p:retryableErrors="4001, 4002"
       p:password="%{JDBCPassword}" />

    <bean id="JDBCStorageService" parent="shibboleth.JDBCStorageService"
          p:dataSource-ref="dataSource"
          p:transactionIsolation="4"
          p:retryableErrors="40001"
     />
