Cause:

Memory Target  error come due to lack of tmp space on server .



[oracle@rac1 ~]$ df -h
Filesystem                   Size  Used Avail Use% Mounted on
/dev/mapper/vg_rac1-lv_root   26G   20G  5.0G  80% /
tmpfs                        1.5G  442M  1.1G  31% /dev/shm
/dev/sda1                    477M   55M  397M  13% /boot

Solution :

Need to increase temp space on server

# umount tmpfs
# mount -t tmpfs shmfs -o size=4048m /dev/shm

Make entry in fstab file on /etc/fstab

How to Restore database using Cold Backup in Noarchivelog Mode Without Online Redo Logs

Restoring a Cold Backup in Noarchivelog Mode Without Online Redo Logs
====================================================================

1. Shut down the instance.
2. Copy the control files and data files back from the backup.
3. Start up the database in mount mode.
4. Open the database with the OPEN RESETLOGS clause.



Step 1. Shut Down the Instance
--------------------------------------------------------------------------------------


$ sqlplus / as sysdba
SQL> shutdown abort;


Step 2. Copy the Files Back(datafiles and controlfiles) from the Backup without redo logfiles backup
----------------------------------------------------------------------------------------------------

$ cp <backup directory>/*.* < database file directory>


Step 3. Start Up the Database in Mount Mode
----------------------------------------------------------------------------------------------------

$ sqlplus / as sysdba
SQL> startup mount



Step 4. Open the Database with the OPEN RESETLOGS Clause
--------------------------------------------------------------------------------------------------

SQL> alter database open resetlogs;

you will get error


ORA-01139: RESETLOGS option only valid after an incomplete database recovery


{SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery}


SQL>


SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-00264: no recovery required


SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open
