12c CDB with PDB as simple as possible



Following on in a pointless series on how to create things as simply as possible here are the steps to create a cdb (and the included initial seed pdb) as simply as possible.

This is the abridged version as there are some issues with the oracle provided scripts that I'll do a long version of the post to describe.

So first up we create as small an init file as possible - this is slightly bigger than my previous example for an old style database (i.e. no cdb or pdb just a 'db').

This is to enable the cdb parameter, make use of db_create_file_dest (to avoid having to specify file names for temp files), and setting a java pool size as the default script for cdb creation installs every possible option.

So we end up with a pfile containing this

db_name='DEMO'
shared_pool_size=1G
enable_pluggable_database=true
java_pool_size=256M
db_create_file_dest='/oracle/DEMO/oradata'


We now just need to set our ORACLE_SID to DEMO (I'm assuming here ORACLE_HOME etc is set)

#export ORACLE_SID=DEMO
#sqlplus / as sysdba

SQL> create database enable pluggable database default temporary tablespace temp;

Now we have the raw cdb (and pdb) created but we need to run catalog/catproc etc against them both - this would be pretty painful but oracle provide a perl wrapper script to simplify this which will run the scripts against all CDB/PDB's in the whole DB.

For the initial creation from scratch there is a master script that calls everything. We are prompted for 3 things but then it just goes away and does its stuff.

So lets run that:

SQL> @catcdb
Enter new password for SYS:
Enter new password for SYSTEM:
Enter temporary tablespace name: temp
