Oracle Database Discussions

Every time when I refresh the db with production db and try to convert to cluster db using rconfig I get this error.
Verified xml file and every thing is correct in it.

rconfig convertTOrac.xml

Converting Database LABDB. to Cluster Database. Target Oracle Home : /u01/app/oracle/product/10.2.0.4/db_1.

I know its a problem with TNS but still i could not figure out where I am going wrong. Here is the TNS.

Parameter:

*.local_listener=LISTENERS_LABDB
*.remote_listener=''

TNS: Same has been updated in all the 3 nodes but still no luck.

LABDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab2-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab3-vip)(PORT = 1521))
(ENABLE = BROKEN)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = LABDB_APPSVR)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
)
)
)


LISTENERS_LABDB =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab2-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = melrhrac2lab3-vip)(PORT = 1521))
)
