Fixed – ORA-00844: Parameter not taking MEMORY_TARGET into account
When you start your database and it throws following error:
ORA-01078: failure in processing system parameters
ORA-00844: Parameter not taking MEMORY_TARGET into account
ORA-00851: SGA_MAX_SIZE 9445460234 cannot be set to more than MEMORY_TARGET 4547687648.
Cause: The SGA_MAX_SIZE parameter is larger than MEMORY_TARGET parameter.
May be you forgot to set the MEMORY_TARGET in the spfile after setting SGA_MAX_SIZE parameter or already set the MEMORY_TARGET parameter but forgot to set SGA_MAX_SIZE to 0.
Now to start your database, you need to remove the SGA_MAX_SIZE parameter from pfile and spfile.
If you are running a spfile, you must need to create a pfile from spfile. First connect with sys user using following command:
C:\>sqlplus /nologSQL*Plus: Release 184.108.40.206.0 Production on Sat Nov 16 11:17:53 2013Copyright (c) 1982, 2010, Oracle. All rights reserved.SQL> conn sys/sys@xe as sysdbaConnected.SQL>
If you are still unable to connect with SYS user, follow below steps:
C:\>set oracle_sid=xeC:\>sqlplus /nologSQL*Plus: Release 220.127.116.11.0 Production on Sat Nov 16 11:19:37 2013Copyright (c) 1982, 2010, Oracle. All rights reserved.SQL> conn sys/sys as sysdbaConnected.SQL>
Once you are connected with database, create pfile from spfile:
SQL> create pfile from spfile;File created.OrSQL> create pfile = 'D:\oraclexe\app\oracle\product\11.2.0\server\dbs\init.ora' from spfile='D:\oraclexe\app\oracle\product\11.2.0\server\dbs\SPFILEXE.ORA';File created.SQL> exitDisconnected
Now, open the dbs directory which contain the newly created pfile and remove following lines from pfile (example based on Oracle 11g express):
Now recreate spfile from pfile:
SQL> create spfile from pfile;File created.
Now startup the database will be successful:
