XTREMELY minimal manual Oracle database creation script

1. Set your ORACLE_SID

export ORACLE_SID=test

export ORACLE_HOME=/path/to/oracle/home

2. Create a minimal init.ora

# $ORACLE_HOME/dbs/init<sid>.ora control_files = (/path/to/control1.ctl,/path/to/control2.ctl,/path/to/control3.ctl)undo_management = AUTOundo_tablespace = UNDOTBS1db_name = testdb_block_size = 8192sga_max_size = 1073741824 #one gigsga_target = 1073741824 #one gig

3. Create a password file

$ORACLE_HOME/bin/orapwd file=$ORACLE_HOME/dbs/pwd<sid>.ora password=oracle entries=5

4. Start the instance

sqlplus / as sysdba

startup nomount

5. Create the database

create database testlogfile group 1 ('/path/to/redo1.log') size 100M, group 2 ('/path/to/redo2.log') size 100M, group 3 ('/path/to/redo3.log') size 100Mcharacter set WE8ISO8859P1national character set utf8datafile '/path/to/system.dbf' size 500M autoextend on next 10M maxsize unlimited extent management localsysaux datafile '/path/to/sysaux.dbf' size 100M autoextend on next 10M maxsize unlimitedundo tablespace undotbs1 datafile '/path/to/undotbs1.dbf' size 100Mdefault temporary tablespace temp tempfile '/path/to/temp01.dbf' size 100M;

Note: there's some other things you can do here, like "ARCHIVELOG" "SET TIME_ZONE =" and "USER SYS IDENTIFIED BY password" and "USER SYSTEM IDENTIFIED BY password"

6. Run catalog and catproc

@?/rdbms/admin/catalog.sql

@?/rdbms/admin/catproc.sql

7. Change passwords

alter user sys identified by whatever;

alter user system identified by whatever;OMF: minimal manual Oracle create database syntax

1. Set your ORACLE_SID

export ORACLE_SID=test

export ORACLE_HOME=/path/to/oracle/home

2. Create a minimal init.ora

# $ORACLE_HOME/dbs/init<sid>.ora control_files = (/path/to/control1.ctl,/path/to/control2.ctl,/path/to/control3.ctl)undo_management = AUTOdb_name = test

db_block_size = 8192

sga_max_size = 1073741824 #one gigsga_target = 1073741824 #one gigdb_create_file_dest = /path/to/datafile/location #OMFdb_create_online_log_dest_1 = /path/to/first/redo_and_control_file/location #OMF

db_create_online_log_dest_2 = /path/to/second/redo_and_control_file/location #OMFdb_recovery_file_dest = /path/to/flash/recovery/area #OMF#note it’s a good idea to also have background_dump_dest, user_dump_dest, and core_dump_dest here as well

3. Create a password file

$ORACLE_HOME/bin/orapwd file=$ORACLE_HOME/dbs/pwd<sid>.ora password=oracle entries=5

4. Start the instance

sqlplus / as sysdba

startup nomount

5. Create the database

create database testcharacter set WE8ISO8859P1national character set utf8undo tablespace undotbs1default temporary tablespace temp;

You can even do this and it will work, the ultimate in minimalism:

create database test;

Note: There's some other things you can do here, like "ARCHIVELOG" "SET TIME_ZONE =" and "USER SYS IDENTIFIED BY password" and "USER SYSTEM IDENTIFIED BY password"

Note 2: This is so minimal because you are using Oracle Managed Files as seen in #2

6. Run catalog and catproc

@?/rdbms/admin/catalog.sql

@?/rdbms/admin/catproc.sql

Standard create Oracle database syntax

After creating your init.ora file with the appropriate parameters you can use the "create database" command in SQL*Plus to create a database:

Make sure that your have your $ORACLE_HOME and $ORACLE_SID set properly and that you sign-on as SYSDBA:

startup nomount;

CREATE CONTROLFILE REUSE DATABASE "OLDLSQ" NORESETLOGSNOARCHIVELOGMAXLOGFILES 16MAXLOGMEMBERS 2MAXDATAFILES 240MAXINSTANCES 1MAXLOGHISTORY 113LOGFILEGROUP 1 ('/u03/oradata/oldlsq/log1a.dbf','/u03/oradata/olslsq/log1b.dbf') SIZE 30M,GROUP 2 ('/u04/oradata/oldlsq/log2a.dbf','/u04/oradata/oldlsq/log2b.dbf') SIZE 30MDATAFILE

'/u01/oradata/oldlsq/system01.dbf',

'/u01/oradata/oldlsq/mydatabase.dbf';
