oerr ora 4031
04031, 00000, "unable to allocate %s bytes of shared memory (\"%s\",\"%s\",\"%s\",\"%s\")"
// *Cause:  More shared memory is needed than was allocated in the shared
//          pool.
// *Action: If the shared pool is out of memory, either use the
//          DBMS_SHARED_POOL package to pin large packages,
//          reduce your use of shared memory, or increase the amount of
//          available shared memory by increasing the value of the
//          initialization parameters SHARED_POOL_RESERVED_SIZE and 
//          SHARED_POOL_SIZE.
//          If the large pool is out of memory, increase the initialization
//          parameter LARGE_POOL_SIZE.  

1.	Decide the name of New database 
2.	ORACLE_SID=ORA10G...  (set into Env variable )
3.	Go to "F:\oracle\product\10.2.0\admin" create new folder (ORA10G)
4.	In ORA10G create new all folders  adump , bdump, cdump, dpdump, pfile, udump
5.	In pfile take a copy of existing init.ora from previous database
6.	You can find this init.ora file into this location  "F:\oracle\product\10.2.0\db_1\database"
7.	Change this init.ora
8.	Change parameters
9.	db_name , instance_name ,control_files ,background_dump
a.	dest,user_dump_dest, 
10.	save this file as "init.ora"
11.	Create new folder in Oradata --- "ORA10G"
12.	To create service--- Go to command prompt ------Oradim
13.	Oradim NEW SID ORA10G SYSPWD ORACLE STARTMODE AUTO SPFILE
14.	Check that service is started or not in Control panel  administrative tools 
-- sevices--OracleserviceORA10g---started
15.	Shut down previously started database
16.	Connect to SQL prompt  as sysdba
17.	create spfile from pfile='F:\oracle\product\10.2.0\admin\ORA10G\pfile\init.ora';
18.	Startup Nomount
19.	Select * from v$instance;
20.	Show parameter instance_name, db_name
