Oracle DB 12c can't start tns service - oracle

Question

Yesterday I restarted my machine and now my DB is unavailable.
I had already some difficulties to run it the first time because there were two different installations of Oracle DB.
The windows services that I suppose they should run:
OracleJobSchedulerFOOBAR
OracleOraDB12Home3MTSRecoveryService
OracleOraDB12Home3TNSListener : OracleOraDB12Home3TNSListener service on your local computer start and stopped. Some service stop automatically if they are not in use by other services or programs.
OracleServiceFOOBAR
OracleVssWriterFOOBAR
So as you can see : I can not start the OracleOraDB12Home3TNSListener service.
I changed the file tnsnames.ora :
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
FOOBAR=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = myurl.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = FOOBAR)
)
)
And my listener.ora is
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\OracleDB\product\12.1.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\OracleDB\product\12.1.0\dbhome_1\bin\oraclr12.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = myurl.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
I already try a lot of things like :
sqlplus / as sysdba and startup but I got
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_FOOBAR'
alter system set local_listener='FOOBAR'; scope=spflile; but I got
*
ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 0
Session ID: 0 Serial number: 0
When I check I the Oracle Administration Assistance for the OracleDB12Home3 :
ORACLE_SDI = FOOBAR
ORACLE_HOME = C:\OracleDB\product\12.1.0\dbhome_1
Does someone has any idea on how to help me?

After long investigations, thanks the help of a colleague, it's working.
To sum up how we did to solve it :
So to fix my first issue 'OracleOraDB12Home3TNSListener can not start' was due to that I had a new IP. So I changed it in my config (...\NETWORK\ADMIN
): https://community.oracle.com/thread/855326
when I was trying to connect with sql developer (after the restart of my computer). I had the error: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist. That was meaning that my DB was not started (http://www.dba-oracle.com/sf_ora_01034_oracle_not_available.htm).
So I try start the db manually sqlplus / as sysdba and startup but I had always this output :
SQL> startup
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'LISTENER_FOOBAR'
To fix I tried to work on the LISTENER.ORA and TNSNAMES.ORA files :
LISTENER.ORA
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\OracleDB\product\12.1.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\OracleDB\product\12.1.0\dbhome_1\bin\oraclr12.dll")
)
(SID_DESC =
(GLOBAL_DBNAME=FOOBAR)
(ORACLE_HOME = C:\OracleDB\product\12.1.0\dbhome_1)
(SID_NAME = FOOBAR)
)
)
LISTENER_FOOBAR =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
TNSNAMES.ORA
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
FOOBAR =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = FOOBAR)
)
)
I try to restart the right windows service several times : OracleServiceFOOBAR but nothing was changing. I had always the same issue. I remember that I did pfile configuration.
So I decided to change the pfile configuration with something like alter system set LOCAL_LISTENER='(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))' scope=both;. Right but I can't apply any command line because the database don't start...
so i created a pfile called init.ora with *.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))' trick from ORA-00119: invalid specification ORA-00132: syntax error. And I started the DB wit this file in parameter SQL> startup pfile=c:\oracledb\admin\XXX\pfile\init.ora
And then it was working.
