hello. as described i want to create db link which will allow me to see mysql tables in oracle.
but i can't create it cause i can't make my listener listen to this mysql.
i have oracle version 11g r2 64 bit. and my linux is redhat 64 bit as well.
i think, i have installed odbc successfully on linux, cause when i use command: isql -v zenoss user pass (zennos is my dsn) it lets me connect from linux and retrieve data.
i have created initzenoss.ora (initDSN.ora) in $oracle_home/hs/admin and it's parameters are:
HS_FDS_CONNECT_INFO = zenoss
HS_FDS_TRACE_LEVEL = OFF
here is my tnsnames.ora file:
ZENOSS =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 123.34.213.12)(PORT = 3306)) //i've just changed ip for security purposes
)
(CONNECT_DATA =
(SERVICE_NAME = ZENOSS)
)
)
and here is my listener.ora file:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orcl.localdomain)(PORT = 1521)) // this listens to oracle database which is installed on linux for remote connections
)
)
LISTENER2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 123.34.213.12)(PORT = 3306)) //this should listen to mysql server but it doesn't...
)
)
SID_LIST_LISTENER2 =
(SID_LIST =
(SID_DESC =
(SID_NAME = zenoss)
(ORACLE_HOME = /opt/app/oracle/product/11.2.0/db_1)
(PROGRAM = dg4odbc)
)
)
ADR_BASE_LISTENER = /opt/app/oracle
ADR_BASE_LISTENER2 = /opt/app/oracle
so why i am getting this error when i try to lsnrctl start listener2?
Error listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=85.118.96.100)(PORT=3306)))
TNS-12545: Connect failed because target host or object does not exist
TNS-12560: TNS:protocol adapter error
TNS-00515: Connect failed because target host or object does not exist

thanks...
