Hi Ganesh

For some reason Oracle cannot read or locate these two files that is why it is not able to start up.

ORA-00312: online log 1 thread 1: '/oracle/QAS/origlogA/log_g11m1.dbf'

ORA-00312: online log 1 thread 1: '/oracle/QAS/mirrlogA/log_g11m2.dbf'

Check that while installation you have provided the same drives for Origlog and Mirrlog.

i already see this problem for resolved i have to do this:

"ALTER DATABASE RECOVER database until cancel;

alter database open resetlogs

alter database backup controlfile to trace

alter database clear logfile '/oracle/SID/origlogA/log_g11m1.dbf'"

Dear Ganesh,

What the error shows that the redologfiles r multiplexed and for some reason the oracle cant read the redo log files in Group 1.

ALTER DATABASE ADD LOGFILE GROUP 6

('....ORACLE\QAS\ORILOGA\LOG_G11M6.ORA','...ORACLE\QAS\ORILOGA\LOG_G11M7.ORA') SIZE 1M;

NOW SHUTDOWN ORACLE & RESTARTIT.

EXECUTE:

ALTER DATABASE DROP LOGFILE GROUP 1;

IT MAY SHOW AN ERROR THAT

LOG 1 IS CURRENT LOG FOR THREAD 1 CANNOT DROP.

IF THIS ERROR SHOWS EXECUTE

ALTER SYSTEM SWITCH LOGFILE;

THIS MAY SHOW AN ERROR DATABASE NOT OPEN

IF SO EXECUTE

ALTER DATABASE OPEN;

WHEN THE DATABASE IS OPEN

EXECUTE

ALTER SYSTEM SWITCH LOGFILE;

IF IT IS SWITCHED

DROP THE LOGFILE GROUP1 BY EXECUTING:

ALTER DATABASE DROP LOGFILE GROUP 1;

IF THE DATABASE ALTERED MSG COMES SHUTDOWN AND RESTART.

WE ADDED A LOGFILE GROUP COZ ATLEAST 2 LOGFILE GROUPS ARE REQUIRED THEN WE DROPPED THE GROUP1.

This has to help and pl dont forget to award a point.

Ganesh,

See what you have at present

select group#, member from v$logfile;Check physically all files are present in the location.

Check How many groups u have select group#, member from v$logfile;

If u have more than 2 groups and the missing ones are from non active group u can drop th esame.let me know

i hope u have more than 2 groups and write perm to '/oracle/QAS/origlogA/'

u r missing members from group1 check physically

To switch u can issue alter system switch logfile;

Let me know if u need more help reg the same

Regards
