Changing the Oracle logo in OBIEE 12c

Most customers want to change the Oracle logo located in the top-left corner of the OBIEE website to their own company’s logo.

obiee12c_oracle_logo

After upgrading from OBIEE 11g to OBIEE 12c, your previous change for this logo will not carry forward, or of course, if you did a new install, you will need to make a change to replace the Oracle logo with your own.  This post explains the simplest way to change the Oracle logo in OBIEE 12c.

Perform a search (recursive search) on file system of your OBIEE 12c server, in all OBIEE directories, for files with “oracle_logo” or “oracle_logo.png”.
Your search will return many directories containing this file.  You will need to change the file in a subset of these directories.

Since you will be likely using the “s_Alta” style in OBIEE 12c, pick out the directories with “s_Alta” in their path.  There should be about 9 directories and they will look like the directories listed below.  If you are not using “s_Alta”, then pick the directories with the appropriate style.

Get your company logo and make it a similar size to the Oracle Logo image.  Rename your company logo file to the name oracle_logo.png.

Go into each of the directories you identified in the above steps, and rename the oracle_logo.png file to oracle_logo.bkup or oracle_logo.orig.
Then, copy your company logo (that is now renamed to oracle_logo.png) into all the directories.

The directory paths may look something like these shown below, but will be different.  If you not using BI Mobile App Designer (bimad) or BI Publisher (bipublisher), you can ignore the bottom 6 directories, and just update the 3 analytics directories.

Good luck with your change.  Thanks for reading!

Issues identified after upgrading from OBIEE 11g to OBIEE 12c

After upgrading our Development environment from OBIEE 11g to OBIEE 12c, we encountered some issues.  This post describes some of the issues we have identified so far and how we resolved them.

  1. Images are missing.
    • This was fixed by moving all images to the new OBIEE 12c images directories.
  2. Dashboards with hidden pages are broken.
    • This was initially resolved by moving the hidden pages to the end of the dashboards list in the dashboard properties dialog.
    • We later discovered that there is an Oracle patch for this, and applying it resolved the issue.
  3. Colors on graphs are different.
    • This will need to be resolved by configuring reports with specific colors.
  4. Some of the graphs scales are changed
    • This was resolved by setting the appropriate graph scale properties.
  5. The order of the items in the legend on some graphs changed
    • This was left as is. It seems there is no “resolution” for this (no way to make it exactly as it was before), but it seems to be ok as is.
  6. Prompts shifted
    • This was resolved by setting the dashboard column objects’ (that contain the prompts) width properties
  7. Dashboard Pages missing after upgrade
    • This was resolved by changing and resaving the dashboard pages in 11g and re-migrating the catalog to 12c.
  8. In some cases, the Subject Areas do not show (missing) in Manage Privileges.
    • A restart of the services resolved this.

 

I will keep adding to this list as new issues are encountered and resolved.

Good luck with your upgrade!

 

Dashboards with hidden pages behave strangely after upgrade to OBIEE 12c

After upgrading from OBIEE 11g to OBIEE 12c, some dashboards behaved strangely.  Things that were wrong include:

  • unable to edit the dashboard from the dashboard page
  • unable to see some of the dashboard pages / tabs
  • click on one tab and it takes you to another tab

It turns out that all the dashboards affected by this behavior were dashboards with hidden pages / tabs.

There is a workaround for this.  The workaround is – move all the hidden pages / tabs to be at the end of the list of dashboards pages in the dashboard properties view.  After doing this, the dashboard will work as expected.

There is also an Oracle patch for this bug.  It is Patch # 23511448.  As of the time of this post, it was still an interim patch and not yet a production patch.  From our perspective, the patch seems to have resolved the issue without causing any new issues.  However, since it’s still an interim patch, apply at your own risk.

Thanks for reading.

Upgrading OBIEE 11g to OBIEE 12c – First thing to ensure

Our team is currently in the process of upgrading our OBIEE 11g environments to OBIEE 12c. I have been gathering information about the process and will be sharing information on our experience as we progress.

I wanted to point of the first thing you want to ensure before planning/starting the upgrade from 11g to 12c – this may save you a little time. Or if you have already started, and encountered an error relating to … catalog version is not supported … then this post might be helpful.

You can upgrade the OBIEE catalog from OBIEE 11.1.1.7.x or OBIEE 11.1.1.9.x to OBIEE 12c. This should upgrade without any major issues.
But you may unexpectedly run into the above problem if you had upgraded the OBIEE 11g catalog using patch sets and had not run the full catalog upgrade. This results in the catalog being used as an 11.1.1.7 or 11.1.1.9 environment, but the version stored in the catalog is still older (such as 11.1.1.3 or 11.1.1.5).
Then when you try to upgrade from OBIEE 11g to OBIEE 12c, you get the error because the catalog is still technically not yet on an approved version for upgrade.

To resolve this, you need to run a full catalog upgrade on the OBIEE 11g catalog. This involves modifying the instanceconfig.xml file as follows:

Change the value of the UpgradeAndExit parameter from “false” to “true” as shown in the example below.

upgradecatalog

Restart the presentation services.
After this is complete, edit the files again and change “true” back to “false“, and restart the presentation services again.

You should now be able to upgrade your catalog to an OBIEE 12c version.

I hope this helps. Thanks for reading.
