12560 Tns: protocol adapter error

2. i found the oracle service is not started it is auto when i start oracleservicedawn in the service and throws error: 1067 unable to start the oracleservicedawn the process terminated unexpectedly.

3. as per forum message i' ve again set Oracle_sid=dawn
and connected in sqlplus> conn system/manager@dawn it prompts
12154:TNS:Could not resolved service name given in the connect descriptor.

my listener and tnsname ora files have the servicename correct.
any one suggest can i delete my oracleservicedawn through oradim
and create a new one in order to secure my precious database
pls suggest how to start my oracleservice to connect to my database. seeking assistance

Is your database mounted and open?
Try this:
1. set Oracle_sid=dawn
2. sqlplus "sys/syspasswordwhateveritisyougave as sysdba"
   if you are logged in as same your you installed oracle
   sqlplus /nolog
   connect /as sysdba
3. Startup

If none of these work, edit your sqlnet.ora , comment all entries
and try again.

12154:TNS:Could not resolved service name given in the connect descriptor

After try "Mahesh" suggestion if problem is persists then check "tnsnames.ora" file "service" clause is some ur oracle_sid if not then correct.

hope this helps.
