DBDriver failed to load, dbd_db2cli.dll (The specified module could not be found)

You may face the following error when you try to setup the repository connection for the performance manager:

DBDriver failed to load : C:\Program Files\Business Objects\BusinessObjects Enterprise 11.5\win32_x86\dataAccess\connectionServer\dbd_db2cli.dll (The specified module could not be found.)

The default path for the DB2 client on the server is at the end of the windows "Path" variable. This is because the 256 character limitation for the "Path" variable.

I solved this problem by editing the "Path" Variable, and put the following directories: D:\IBM\SQLLIB\BIN;D:\IBM\SQLLIB\FUNCTION;D:\IBM\SQLLIB\SAMPLES\REPL
in the at the start of the "Variable Value" ( they were at the last) and restarted the computer and it worked well.
