Hi Kishore,
When you ran brconnect earlier (for the password), it was in /usr/sap/W22/SYS/exe/run (which is normally a symbolic link), so it must exist somewhere. Can you run following commands:
ls -l /usr/sap/W22/SYS/exe
find /sapmnt/W22 -name brconnect
If necessary we can always patch control.xml to adapt the brconnect path, but obviously we first need to know where it is exactly.
Regards,
Mark
