Oracle Create Database Parameters tips

Expert Oracle Database Tips by Donald BurlesonDecember 15, 2015

Question: :  What parameters are involved when creating a database?  Can create database parameters be changed?

Answer:  The create database parameters set up the whole database.  Follow the link for some important create database parameters.

Some immutable create database parameters like the character set and block size because the whole database must be changed and recreated.

Other create database parameters can be changed more easily, like here, how to change your maxdatafiles create database parameter.

Here is an example of create database parameters at creation time:

create database
    test logfile group 1 ('/path/to/redo1.log') size 100M,
             group 2 ('/path/to/redo2.log') size 100M,
             group 3 ('/path/to/redo3.log') size 100M
character set WE8ISO8859P1
national character set utf8
datafile '/path/to/system.dbf' size 500M autoextend on next 10M maxsize unlimited extent management local
sysaux datafile '/path/to/sysaux.dbf' size 100M autoextend on next 10M maxsize unlimited
undo tablespace undotbs1 datafile '/path/to/undotbs1.dbf' size 100M
default temporary tablespace temp tempfile '/path/to/temp01.dbf' size 100M;

 Follow the link for my notes on other create database parameters.
