Kerberos Authentication to Oracle from Teiid

In this article I will show step by step instructions on how to configure WildFly server running Teiid to participate in Kerberos login into Oracle database. This article also shows how the kerberos ticket is used for credential delegation to Oracle and also using Teiid OData Rest Web Service.

See https://developer.jboss.org/docs/DOC-55813 for full details.

Teiid 9.2 Alpha1 Released

Teiid 9.2 Alpha1 has been released.  Feature highlights so far:
In progress features:

  • Also using Teiid as a Postgres/Postgis source for qgis is nearly complete.
  • The build has been revamped to support our integration with WildFly Swarm.  Swarm provides a powerful new mechanism for embedding Teiid with the full power of the application server.  See an example/description at https://github.com/teiid/wildfly-swarm-teiid
  • It's not in this alpha, but a lot of work has been completed toward a more complete DDL metadata system.  Please follow this and other issues if you are interested in contributing.

We'll continue to shoot for a pre-release about every two weeks and still expect the final release in about 3 months.

Teiid 9.1.1 Released

Teiid 9.1.1 has been posted.  It addresses 7 issues:
  • [TEIID-3755] - Allow embedded to set the default authentication type
  • [TEIID-4499] - OData Kerberos cannot access VDB
  • [TEIID-4535] - Issues with EventDistributor
  • [TEIID-4541] - trustAllLocal works even for remote connections
  • [TEIID-4546] - On setting jboss-teiid cluster : throwing java.lang.IllegalArgumentException.
  • [TEIID-4547] - getQueryPlan fails in adminapi
  • [TEIID-4530] - Add semicolons to generated ddl
The most significant of which is a security issue - TEIID-4541.  If you are allowing remote JDBC connections, not using data roles, and have left trustAllLocal at the default setting, then remote connections that specify PassthroughAuthentication=true are also being allowed.  Please upgrade or alter your settings to prevent this.

The pace of fix releases for 9.0.x will now be much slower and end with the release of 9.2 Final.  The first alpha release of 9.2 should be available by the end of the week.

A fix release for 9.1 including TEIID-4541 will be available for 9.1 by Monday.  The first alpha release of 9.2 should be available by the end of next.

  • [TEIID-4360] - default token type needs to be "bearer" for OAuth2 access code negotiation
  • [TEIID-4405] - delete using in statement does not remove records from temporary table

  • [TEIID-4463] - No results with cross source outer join and offset only
  • [TEIID-4471] - Assertion error with temp table delete
Please upgrade to 9.x when possible, and please consult the release notes and the documentation to minimize potential issues.

Data Quality and Data Cleansing

We are very excited to announce that we have been working with Open Source Data Quality (OSDQ) community to bring Data Quality and Data Cleansing tools to Teiid. The OSDQ community released their latest Profiler UI tool 6.1.8 with built in first class support for Teiid, for which we sincerely grateful. This tool has many advanced Data Quality and Data Cleansing features, and we hope you give it try and give your feed back. Here are some videos to get you started with this tool.
If you have questions or suggestions on this tool, you can use Teiid forums to ask questions. The community leaders from OSDQ will also be monitoring Teiid forms.

What's Coming Up?

9.2 work is well underway - with a couple of BIG usability features. One of them is FULL DDL support - where Teiid will allow the creation of a VDB just using DDL in an ad-hoc manner just like any RDBMS. We are implementing much of the SQL-MED specification to accommodate the feature. We will also have support for WildFly Swarm.  Swarm can change forever the way you will build your Teiid applications in Microservices area or just as an another embedded application. There will be lot more talk and blogs about this in coming months on these topics. If you are interested please get INVOLVED!

Community, Community, Community

We are seeing steady increase in participants in all forms for which we are very grateful, we can't thank you enough. So, keep those questions rolling, express your opinions and STAY involved. Don't be shy with new ideas, we need to keep pace with market trends folks! and we can't do it without YOUR involvement.

Thank you.

Ramesh & Steve.
