Question: What do
I do to manually create a cdb from the command line? I
know that Oracle recommends using DBCA to create a cdb, but
I need to do a manual create of a cdb. What are the
steps to manually create a cdb from the SQL*Plus command
prompt?
Answer: To manually create a cdb
you need to perform these steps.
1 - Parameter: Set the init.ora
parameter enable_pluggable_database=true.
2 - Create the database: You can
run the following create statement for a cdb, making sure to
include the "enable pluggable database" syntax:
CREATE DATABASE ZWC
MAXLOGFILES 16
MAXLOGMEMBERS 4
MAXDATAFILES
1024
MAXINSTANCES 1
MAXLOGHISTORY
680
CHARACTER SET ZHS16GBK
NATIONAL
CHARACTER SET AL16UTF16
DATAFILE
'/12cfile/ZWC/system01.dbf' SIZE 500M
EXTENT MANAGEMENT LOCAL
UNDO TABLESPACE undotbs1 DATAFILE
'/12cfile/ZWC/undotbs01.dbf' SIZE
800M
SYSAUX DATAFILE
'/12cfile/ZWC/sysaux01.dbf' SIZE
500M
DEFAULT TEMPORARY TABLESPACE TEMP
TEMPFILE
'/12cfile/ZWC/temp01.dbf' SIZE
500M
DEFAULT TABLESPACE USERS DATAFILE
'/12cfile/ZWC/users01.dbf' SIZE
50M
LOGFILE GROUP 1
('/12cfile/oraredo/ZWC/redo01a.rdo')
SIZE 50M,
GROUP 2
('/12cfile/oraredo/ZWC/redo02a.rdo')
SIZE 50M
USER sys IDENTIFIED BY oracle
USER system IDENTIFIED BY oracle
USER_DATA TABLESPACE userstbs
DATAFILE
'/12cfile/ZWC/userstbsp01.dbf'
SIZE 500M
ENABLE PLUGGABLE DATABASE
SEED FILE_NAME_CONVERT =
('/12cfile/ZWC','/12cfile/ZWC/pdbseed');
3 - Catalog: Run the catalog
script (catcdb.sql) after the create database statement. The Oracle
docs note:
"When you use the CREATE DATABASE
statement to create a CDB, you must complete additional
actions before you have an operational CDB.
These actions include building views
on the data dictionary tables and installing standard PL/SQL
packages in the root.
You perform these actions by running
the supplied "catcdb.sql" script."
Important Note: You must have have
the perl binaries in your path when you run catcdb.sql. Else
you will get the
ORA-01917 error.
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/perl/bin/:$PATH
After doing this PATH change, you run catcdb.sql and then
you will be able to create the pluggable database
successfully.
