YOu installed a new oracle database of name HTGORA.
Then Automatically oracle must have created an instance of the name HTGORA.
YOu have all the controlfiles,datafiles of the previous database.
JUst shutdown the new database.Overwrite all the existing files to the previous datafiles.
Recreate password file.
startup

Sir, i dismouted the database and i copied every file of old database into new database.
orasrv(old instance) & HTGORA (NEW INSTANCE)
copy d:\oracle\admin\ORASRV d:\oracle\admin\HTGORA
copy d:\oracle\oradata\orasrv\*.* d:\oracle\oradata\htgora\*.*
and i write the password too.
but after a restart, i found
first "TNS LISTER COULD NOT RESOLVE THE SERVICE NAME"
and after a two or 3 tries, i m getting this,
"ORA-01033 oracle initialization or shutdown in progress"
SIR, i need the data, pls guide me to solve this problem sir;

BRIAN SIR, thanks for your reply,
i tryed with oradim
ORADIM -startup -sid orasrv -usrpwd manager -starttype SRVC,INST -pfile D:\ORACLE\ADMIN\ORASRV\PFILE\INIT.ORA
DIM-00011: The service does not exists
O/S-Error: (OS 1060)The specified service does not exists as an installed service.
Sir,since the OS was corrupted, i repaired the OS and REGISTRY.
everything working fine except oracle.I went into services.msc to start the oracle services;
i found no services named in oracle.
i searched through registry for oracle.exe; i found no entries;
so i reinstalled the ORACLE,and i take backup of d:\oracle\oradata\*.* and
d:\oracle\admin\*.*
And i installed new instance HTGORA in the same OS.
THE old oracle instance, not working was, ORASRV.
pls instruct me, how to solve this problem;
I want the data from ORASRV instance;
i have all the control files and spfile
sir, dont mistake me, pls do the favour in time , Thank u sir,
Bala

Query for help by specifying the following parameters: -? | -h | -help
Use -NEW to create a new service/instance.
| Quote: | And i installed new instance HTGORA in the same OS.
THE old oracle instance, not working was, ORASRV.
|
The db_name parameter in ora.init must be the same the db name in files, that the old name.

Michel
