Auto Debugger

Hi
I’m trying to use debug option with a procedure. But when I press execute, it shows this message “UNABLE TO FIND RAC CONNECTION INFORMATION FOR RACCELR (INST_ID=2)”
I found some information and it says that Oracle doesn’t support debugging accros RAC instances
We have a RAC instances and It works without any problem. What can I do to sort it out?
This is the tnsnames that i’m using

RACCELR.CLINICAROSARIO.COM.CO =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.102)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.105)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = raccelr)
)
)

Thank you so much por your help
