An Interesting Problem with ODI: Unable to retrieve user GUID

One of my customers had a problem about logging in to Oracle Data Integrator (ODI) Studio. Their ODI implementation is configured to use external authentication (Microsoft Active Directory). The configuration was done years ago. No one modified it since it’s done, in fact most people even do not remember how it’s configured. Everything was fine until they started to get “ODI-10192: Unable to retrieve user GUID” error.

Oracle Cloud Day Istanbul

Yesterday, I spoke at the Oracle Cloud Day Istanbul. It was an amazing event. The venue (Swissotel the Bosphorus) was great, the conference rooms were comfortable, the presentations were attractive and well-balanced (DB, Middleware, Development), and the audience was great. This year, the event was much more crowded than previous years.

As usual, Oracle Turkey set a separate track for TROUG (Turkish Oracle User Group) presentations, and I was one of the speakers of TROUG. As TROUG, we appreciate Oracle Turkey’s support to us. Personally, I would like to thank them for this successful organisation. As I said, everything was great.

Oracle Database on the Docker Store

You probably know that there’s an official github repository storing Dockerfiles and samples to build Docker images for Oracle products and Open Source projects. Now Oracle takes one more step to support Docker. Oracle Brings Oracle’s Flagship Databases and Developer Tools to the Docker Store (you can read the official announcement). Oracle Linux was already on the Docker Store. Oracle Database Enterprise Edition, Oracle client tools, Oracle Weblogic, Oracle Coherence, Java 8 SE are also released on the Docker Store. Now you don’t need to build the image, you can download and use the image from the Docker Store.

Using EMCLI for Mass Update a Property Value

Here’s a quick and simple script which can help you to update a target property value of all targets running on a specific host. The script will expect you to enter 3 parameters: host name, property name and property value. Then it will search for the targets running on the given host name, and set the property to the given value:

It’s better to enter the property name in double quotes, because property names can contain spaces (for example “Line of Business”).

The script first checks the number of parameters, then login to OMS (enter your credentials – if you enter username but do not enter password, EMCLI will ask you to enter password when you run the script), gets the targets running on the given host (using EMCLI list command), and then executes set_target_property_value for each target. You may notice I give a non-default separator because some target names can contain colon (:) sign.

How Enterprise Manager Detects the Version of Oracle Databases

You know that patch numbering has been changed since November 2015, and the new format replaces the numeric 5th digit of the bundle version with a release date in the form “YYMMDD”. Let’s say you applied PSU 160719 to your database, the exact version of your database becomes We also know that PSUs do not change the Oracle release version information that can be queried from v$version (Doc ID 861152.1), so when you query your database, you still see

On the other hand, when you list your database targets on Oracle Enterprise Manager, it shows the exact version of Oracle Database.
