report builder not open (minimized in taskbar)

Unable to Open Reports Builder 11g (ICON Appears Minimized in Taskbar)

-->

This  is a known issue where if you try to launch Reports Builder 11g in Windows 7 , the Reports Builder will not launch. However, the icon for it appears in the Windows taskbar. 

To fix the problem, follow these steps:

1.  Go to D:\oracle\devsuitehome_1\

2.  Make a backup of cauprefs.ora

3.  Look for these entries:

Reports.root_x = “#####”

Reports.root_y = “#####”

4.  Replace the numbers (represented by #####) with 0 so that they look like this:

Reports.root_x = 0

Reports.root_y = 0

5.  Save and close the file

6.  Launch Reports Builder. Reports Builder should work successfully.

NOTE: If you open up Reports Builder at a later date and the problem reoccurs, open up cauprefs.ora and modify the same parameters again with the following:

Reports.root_x = 80
Reports.root_y = 30
Reports.root_y = 76

After applying the settings above, Reports Builder should open successfully(1478627.1)
