STEPS TO CREATE DATABASE MANUALLY ON LINUX
Step 1:
First create all the necessary directories. Followings are my directories:
| testdb1]$ ls |
| admin backup archive |
| admin]$ ls |
| adump bdump cdump udump |
Step 2:
Next prepare the database creation script. Following is my script “testdb1.sql”
| CREATE DATABASE “testdb1” |
| MAXLOGFILES 5 |
| MAXLOGMEMBERS 5 |
| MAXDATAFILES 100 |
| MAXINSTANCES 1 |
| MAXLOGHISTORY 292 |
| LOGFILE |
| GROUP 1 ‘/d02/monish/testdb1/redo1.log’ SIZE 10M, |
| GROUP 2 ‘/d02/monish/testdb1/redo2.log’ SIZE 10M, |
| GROUP 3 ‘/d02/monish/testdb1/redo3.log’ SIZE 10M |
| DATAFILE |
| ‘/d02/monish/testdb1/system.dbf’ size 100m, |
| ‘/d02/monish/testdb1/usr04.dbf’ size 10m |
| sysaux datafile ‘/d02/monish/testdb1/sysaux.dbf’ size 100m |
| undo tablespace undotbs |
| datafile ‘/d02/monish/testdb1/undo.dbf’ size 50m |
| CHARACTER SET US7ASCII |
| ; |
Step 3:
Prepare the init file. Like this one [inittestdb1.ora]
| *.audit_file_dest=’/d02/monish/testdb1/admin/adump’ |
| *.background_dump_dest=’/d02/monish/testdb1/admin/bdump’ |
| *.compatible=’10.2.0.3.0′ |
|
*.control_files=’/d02/monish/testdb1/control01.ctl’, ‘/d02/monish/testdb1/control02.ctl’,’/d02/monish/testdb1/control03.ctl’ |
| *.core_dump_dest=’/d02/monish/testdb1/admin/cdump’ |
| *.db_block_size=8192 |
| *.db_domain=” |
| *.db_file_multiblock_read_count=16 |
| *.db_name=’testdb1′ |
| *.dispatchers='(PROTOCOL=TCP) (SERVICE=indiaXDB)’ |
| *.job_queue_processes=10 |
| *.log_archive_dest_1=’LOCATION=/d02/monish/testdb1/archive’ |
| *.log_archive_format=’%t_%s_%r.dbf’ |
| *.open_cursors=300 |
| *.pga_aggregate_target=200278016 |
| *.processes=150 |
| *.remote_login_passwordfile=’EXCLUSIVE’ |
| *.sga_target=601882624 |
| *.undo_management=’AUTO’ |
| *.undo_tablespace=’UNDOTBS’ |
| *.user_dump_dest=’/d02/monish/testdb1/admin/udump’ |
| *.db_recovery_file_dest=’/d02/monish/testdb1/backup’ |
| *.db_recovery_file_dest_size=2147483648 |
Step 4:
Now perform the following steps:
| $ export ORACLE_SID=testdb1 |
| $ sqlplus / as sysdba |
| SQL*Plus: Release 10.2.0.3.0 – Production on Thu May 22 17:35:28 2008 |
| Copyright (c) 1982, 2006, Oracle. All Rights Reserved. |
| Connected to an idle instance. |
| SQL> startup pfile=/u01/app/oracle/product/10.2.0/db_1/dbs/inittestdb1.ora nomount |
| ORACLE instance started. |
| Total System Global Area 603979776 bytes |
| Fixed Size 1263176 bytes |
| Variable Size 167774648 bytes |
| Database Buffers 427819008 bytes |
| Redo Buffers 7122944 bytes |
| SQL> @testdb1.sql |
| Database created. |
Step 5:
So your database is create. Now just run the catalog.sql and catproc.sql scripts.
You will find the in $ cd $ORACLE_HOME/rdbms/admin
| SQL> @/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catalog.sql |
| SQL> @/u01/app/oracle/product/10.2.0/db_1/rdbms/admin/catproc.sql |
| SQL> select name from v$database; |
| NAME |
| ——— |
| TESTDB1 |
Okay, now your database is ready to use…
