  2. Contents • Overview of the Grouper API • Versioning • Download • Databases • Grouper Loader • DDL • Quickstart data

  3. Grouper components as of v2.0

  4. Overview of the Grouper API • The Grouper registry is the database tables where the Grouper data lives • The Grouper API is • the grouper.jar (and dependent jars) and • configfiles that query and manipulate the Grouper registry • The Grouper API is a dependent component to the UI, WS, Grouper Loader (daemons), and LDAPPC-NG

  5. Overview of the Grouper API (continued) • The Grouper API can run in multiple places for the same registry • The Grouper Java API (from grouper.jar) is also referred to as the Grouper API

  6. Versioning • Grouper API versioning is a three number system • Example: Grouper 2.0.3 • 2 is the major version number • 0 is the minor version • 3 is the build number

  7. Versioning (continued) • Only bug fixes and small impact enhancements will be put in next build number of a major/minor release • Generally a substantial release (new major or minor number) is done yearly

  8. Versioning (continued) • All components of Grouper are released at the same time with the same version number • Note: the Provisioning Service Provider is not on the same release schedule as other Grouper components • If you are upgrading Grouper, it is generally a good idea to upgrade all Grouper components together • For each major/minor release, refer to the • Upgrade instructions • List of environment changes

  9. Versioning for Web Services • Grouper WS are versioned • Each request sends the protocol version that is expected to be returned • Grouper WS are backwards compatible • Clients do not need to be upgraded when the server is

  10. Download • Grouper packages of all official versions are hosted on the Grouper web server linked from: • http://www.internet2.edu/grouper/software.html • If you download the Grouper Installer, it can download most other packages for you • Some Grouper packages are hosted on Maven's central repository

  11. Databases • Grouper uses the open source Hibernate library for Java / SQL persistence • Generally Grouper supports all the databases that Hibernate supports, as long as it supports: • Transactions • Large indexes • Complex SQL queries

  12. Databases (continued) • It is best if you use Oracle, MySQL, or Postgres • Grouper is also tested with SQL server, though its indexes can be problematic • It is unsupported to use another database except HQL in development

  13. Grouper Loader • The Grouper Loader can keep groups in sync with SQL databases or LDAP • The Grouper Loader is compatible with any SQL database that you have a Java driver for (it does not have to be the Grouper registry database) • The Grouper Loader uses simple SQL and not hibernate • Generally it is a good idea to keep your Loader query in a database view

  14. grouper.hibernate.properties config file

  15. Database DDL • DDL is Data Definition Language • This is the SQL that creates the database objects (tables, views, indexes, etc.) used by Grouper • DDL is not standard across database vendors • Hibernate does not give fine-grained control of DDL

  16. Database DDL (continued) • Grouper uses Jakarta DDLUtils to generate DDL for each database vendor • You can run a GSH command to initialize or upgrade the DDL in your database • Grouper will analyze the database to upgrade it • Follow the Grouper upgrade instructions carefully

  17. Database DDL (continued) • Grouper GSH can either: • Init/upgrade the registry for you-or- • Generate a script that you can review • The Grouper GSH DDL command can also run SQL to affect the data in the database on upgrades

  18. Database DDL continued

  19. Database DDL (continued)

  20. Quickstart data • There are quickstart users for a SQL datasource • There is an export of a quickstart project that you can import into your registry to have sample groups, etc. • The Grouper Installer or GSH can install the quickstart users and data for you • The quickstart users need to be resolvable before the quickstart data can be loaded

  21. Quickstart data (continued)
