Manually create database 12c -NON CDB

We are going to see about manual database creation on oracle 12c nonCDB

When we get the request to create a database on a Linux server. The basic prerequisite we need to check

DBNAME
SGA and PGA parameters
controlfile and logfile multiplexing
How many logfiles (Groups and members)
Alter log destination
User datafiles  and its size. 
Archive log destination

Create a pfile in $ORACLE_HOME/dbs/initdemodb.ora( assuming dbname as demodb)

Generally i used to give the below parameters

*.audit_file_dest='/DATA/app/oracle/admin/demodb/adump'
*.compatible='12.2.0.0.0'
*.control_files='/DATA/app/oracle/oradata/demodb/control01.ctl','/orapsr12tr2/app/oracle/oradata/demodb/control02.ctl','/orapsr12tr3/app/oracle/oradata/demodb/control03.ctl'
*.db_block_size=16384
*.db_cache_size=2048M
*.db_domain='world'
*.db_file_multiblock_read_count=16
*.db_files=1000
*.db_name='demodb'
*.diagnostic_dest='/DATA/app/oracle'
*.filesystemio_options='SETALL'
*.LOG_ARCHIVE_DEST_1='LOCATION=/orapsr12tr3/app/oracle/admin/demodb/archive'
*.LOG_ARCHIVE_FORMAT='demodb_%t_%s_%r.arc'
*.open_cursors=1200
*.pga_aggregate_target=1024M
*.processes=3000
*.remote_login_passwordfile='EXCLUSIVE'
*.resumable_timeout=21600
*.sessions=3305
*.sga_max_size=21474836480
*.sga_target=21474836480
*.shared_pool_size=1024M
*.streams_pool_size=100M
*.undo_management='AUTO'
*.undo_retention=10800
*.undo_tablespace='UNDOTBS1'

 

Create appropriate directories and then

[oracle@sdbt1 dbs]$ vi initdemodb.ora
[oracle@sdbt1 dbs]$ export ORACLE_SID=demodb
[oracle@sdbt1 dbs]$ sqlplus

Then create the database using the below script.

CREATE DATABASE demodb 
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 1000
MAXINSTANCES 1
MAXLOGHISTORY 1168
EXTENT MANAGEMENT LOCAL
LOGFILE
GROUP 1 (
'/DATA/app/oracle/oradata/demodb/redo01_a.log',
'/DATA/app/oracle/oradata/demodb/redo01_b.log'
) SIZE 1000M BLOCKSIZE 512,
GROUP 2 (
'/DATA/app/oracle/oradata/demodb/redo02_a.log',
'/DATA/app/oracle/oradata/demodb/redo02_b.log'
) SIZE 1000M BLOCKSIZE 512,
GROUP 3 (
'/DATA/app/oracle/oradata/demodb/redo03_a.log',
'/DATA/app/oracle/oradata/demodb/redo03_b.log'
) SIZE 1000M BLOCKSIZE 512,
GROUP 4 (
'/DATA/app/oracle/oradata/demodb/redo04_a.log',
'/DATA/app/oracle/oradata/demodb/redo04_b.log'
) SIZE 1000M BLOCKSIZE 512,
GROUP 5 (
'/DATA/app/oracle/oradata/demodb/redo05_a.log',
'/DATA/app/oracle/oradata/demodb/redo05_b.log'
) SIZE 1000M BLOCKSIZE 512
DATAFILE

;

 

Then run the below scripts from SQL*Plus as sysdba

@?/rdbms/admin/catalog.sql

@?/rdbms/admin/catproc.sql

@?/rdbms/admin/utlrp.sql

 

Check if the above scripts ran fine

SQL> col compname format a30
SQL> col comp_name format a30
SQL> l
1 select
2 comp_name,
3 status,
4 version
5* from dba_registry
SQL> /

After this run the below script as system .

SQL> @?/sqlplus/admin/pupbld
