Instance not accessible (ora-12514) and recovery..

Question

So, I was doing some changes on a network (from dhcp to fixed ip's), and after that I was not able to access my oracle (10.2.0) instance (win xp), and I don't know why.
Of course, listener starts (and I can tnsping it), but when I start instance, no memory is consumed, like it does not starts (thus I receive ora-12514 error). I didn't changed anything, no db_name, port, tnsnames.ora... anything..
so, now I guess if I do physical backup (datafiles, redo log files, control files, pwd file), and recreate instance (reinstall oracle) can I restore db at that way?

Answer 1

well, this is LISTENER.ORA
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\ora10)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = da1.lan)(PORT = 1522))
this is TNSNAMES.ORA
ORA10 =
(DESCRIPTION =
(ADDRESS =
(PROTOCOL = TCP)
(HOST = da1.lan)
(PORT = 1522)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10.da1)
in sp file and init.ora, db is named 'ora10'.
service name (win xp) is OracleServiceORA10
listener service name is: Oracleora10TNSListener
in oradim.log file there is:
Wed Jan 28 00:33:44 2009
D:\oracle\product\10.2.0\ora10\bin\oradim.exe -startup -sid ora10 -usrpwd * -log oradim.log -nocheck 0
Wed Jan 28 00:33:46 2009
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_ORA10'
