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!
