The purpose of these files is to correct an IBM Rational licensing problem at the FLEXlm level. It is important to note that this problem proved to be specific to certain third party VPN or firewall products. IBM Rational successfully reproduced the issue with Qbik Wingate and Aventail products and has verified that the fix corrects the problem in a test environment. Considering the nature of the problem, IBM Rational does not guarantee the files will work in all environments. If after applying the patch you are still experiencing the issue, Please try one of the other resolutions provided above. If the problem then persists please contact IBM Rational customer support.

Note: Also note that upgrading to Aventail 5.0 also resolves the issue.

Note: Before installing these files it is important to make sure you can first reproduce the "FLEXlm -12" error.

1. On a client machine, run the Rational product using a floating license key and verify that the product fails with the "FLEXlm -12" error.
2. If the product runs, it may be able to run due to a local temporary license key.
3. The temporary license keys are written to the following file:
   <rational>\common\rational_temp.dat
4. Rename that file to rational_temp_orig.dat if you have temporary Nodelocked keys.

Hot Fix installation Instructions:

1. Open Windows Explorer and navigate to the following directory:
   <install dir>\Rational\common
2. In the "common" folder, locate the files below and rename them something other than their original names (example licadmin.old). The purpose of this is to allow you to change your machine back to its original state if needed.
   
   licadmin.exe
   lmgrd.exe
   rational.exe
   license.dll
   licensing.dll
   rscommonui.dll
   suite objects.dll
3. Download the attached text file:
   119315603_Rational-FLEXlm70h.zip_1-14RT7W_1-U2WN.txt
   Rename the file to:
   119315603_Rational-FLEXlm70h.zip
4. Extract the files in this zip file to the following directory:
   <install dir>\Rational\common
5. Launch the License Key Administrator (Start > Run type licadmin.exe). You should now see the gray "served by" lines, and launch your IBM Rational products using floating licenses.
