Startup Oracle DB with different version of excutable..!?
I've an Oracle DB in version 7.2.0 but lost the oracle executables.....
is it possible to use other verison of oracle executable to open and mount the DB?
The oldest oracle i can found is 7.2.3!
if not, any suggestion to startup the DB??
THX,
Warren

Re: Startup Oracle DB with different version of excutable..!?
I it will work if you have the init.ora file.
But I would take a backup of all datafiles before trying this action

Re: Startup Oracle DB with different version of excutable..!?
actually, the $ORACLE_HOME was lost and also the init.ora and the listener configure.
Can i use the default parameters to startup the DB? of course i need to point to the correct control files in the init.ora
THX,
Warren

Re: Startup Oracle DB with different version of excutable..!?
before you try anything, please do a full backup.
if you have a copy of the database controlfile, maybe you can get back to operations quite easily...
is your database still up?
kind regards

Re: Startup Oracle DB with different version of excutable..!?
your version is not to far off.
first you can go to nomount state to debug
your new init.ora file.
Once you have achieved that you can
check the control file(s) by going
to mount state.
You may need to run the catproc again !!
(it doesn't do any harm anyway if you do)
from there you can open with a
open resetlogs.
Good luck

Yes it should work with the default parameters in init.ora. As you mentioned change the parameter file to point to the correct location of the control files, and also check the number and the names of the rollback segments defined are the same as defined in the database.
And as Yogeeraj mentioned, it is good to take a full backup of the DB.

I need to make sure the procedure and it will work
MANY THX!!

Re: Startup Oracle DB with different version of excutable..!?
If I don't know the name of the RBS, could I startup the DB in nomount and re-create a new group of RBS?
THX.

If you do not know the rollback segment names and the number of them, then you can comment this line in the init.ora file before starting the database.
