ADRCI - Batch Mode

Dear Friends, 

   I am trying to write a Bastch script to purge the trace files from my Diag using ADRCI. I am following the commands as mentioned in the Doc

  http://docs.oracle.com/cd/B28359_01/server.111/b28319/adrci.htm#BGBGCJDC : 

Using ADRCI in Batch Mode

My database version in 11.2.0.2 and I am working on Windows. 

   I have a problem setting the HOMEPATH as I have more that 2 Oracle_homes in this server. The below is the script that I am trying, however struggling to set the HOMEPATH using the below one and stuck proceeding further. 

C:\Oracle\product\11.2.0\dbhome_1\bin\ADRCI SET HOMEPATH diag\rdbms\b27d1112\b27d1112
