After making a clean installation of eZ Publish 4.6, with Oracle, and upgrading to eZ Publish 4.7 rc1 I get the following in the Database Consistency Check:

The database is not consistent with the distribution database.

To synchronize your database with the distribution setup, run the following SQL commands:

ALTER TABLE ezcontentclass_attribute MODIFY (data_float1 DOUBLE PRECISION);
ALTER TABLE ezcontentclass_attribute MODIFY (data_float2 DOUBLE PRECISION);
ALTER TABLE ezcontentclass_attribute MODIFY (data_float3 DOUBLE PRECISION);
ALTER TABLE ezcontentclass_attribute MODIFY (data_float4 DOUBLE PRECISION);
ALTER TABLE ezcontentobject_attribute MODIFY (data_float DOUBLE PRECISION);
ALTER TABLE ezpending_actions ADD id INTEGER NOT NULL;
ALTER TABLE ezpending_actions ADD PRIMARY KEY ( id );
ALTER TABLE ezx_ezpnet_module_branch ADD branch_id INTEGER DEFAULT 0 NOT NULL;

CREATE TABLE ezstarrating (
contentobject_attribute_id INTEGER DEFAULT 0 NOT NULL,
contentobject_id INTEGER DEFAULT 0 NOT NULL,
rating_average FLOAT DEFAULT 0 NOT NULL,
rating_count INTEGER DEFAULT 0 NOT NULL,

);

CREATE SEQUENCE s_starrating_data;

CREATE TABLE ezstarrating_data (

contentobject_id INTEGER DEFAULT 0 NOT NULL,
created_at INTEGER DEFAULT 0 NOT NULL,
id INTEGER NOT NULL,
rating FLOAT DEFAULT 0 NOT NULL,
session_key VARCHAR2(32) NOT NULL,
user_id INTEGER DEFAULT 0 NOT NULL,
PRIMARY KEY ( id )
);

CREATE OR REPLACE TRIGGER ezstarrating_data_id_tr
BEFORE INSERT ON ezstarrating_data FOR EACH ROW WHEN (new.id IS NULL)
BEGIN
SELECT s_starrating_data.nextval INTO :new.id FROM dual;
END;
/

CREATE INDEX contentobject_id_co_attr_id ON ezstarrating_data ( contentobject_id, contentobject_attribute_id );

CREATE INDEX user_id_session_key ON ezstarrating_data ( user_id, session_key );

CREATE TABLE ezgmaplocation (
address VARCHAR2(150),
contentobject_attribute_id INTEGER DEFAULT 0 NOT NULL,
contentobject_version INTEGER DEFAULT 0 NOT NULL,
latitude FLOAT DEFAULT 0 NOT NULL,
longitude FLOAT DEFAULT 0 NOT NULL,
PRIMARY KEY ( contentobject_attribute_id, contentobject_version )
);

CREATE INDEX latitude_longitude_key ON ezgmaplocation ( latitude, longitude );

CREATE TABLE ezm_block (
block_type VARCHAR2(255),
fetch_params CLOB,
id CHAR(32) NOT NULL,
is_removed INTEGER DEFAULT 0,
last_update INTEGER DEFAULT 0,
name VARCHAR2(255),
node_id INTEGER DEFAULT 0 NOT NULL,
overflow_id CHAR(32),

);

CREATE INDEX ezm_block__is_removed ON ezm_block ( is_removed );

CREATE INDEX ezm_block__node_id ON ezm_block ( node_id );

CREATE TABLE ezm_pool (
block_id CHAR(32) NOT NULL,

node_id INTEGER DEFAULT 0 NOT NULL,
object_id INTEGER DEFAULT 0 NOT NULL,
priority INTEGER DEFAULT 0,
rotation_until INTEGER DEFAULT 0,
ts_hidden INTEGER DEFAULT 0,
ts_publication INTEGER DEFAULT 0,
ts_visible INTEGER DEFAULT 0,
PRIMARY KEY ( block_id, object_id )
);

CREATE INDEX ezm_pool_block_id_ts_hidden ON ezm_pool ( block_id, ts_hidden );

CREATE INDEX ezm_pool_block_id_ts_visible ON ezm_pool ( block_id, ts_visible );

CREATE INDEX ezm_pool_block_id_ts_publ_prio ON ezm_pool ( block_id, ts_publication, priority );

Steps to reproduce

1. Make a clean installation of Ez Publish 4.6
2. Activate the EzOracle extension, by adding ActiveExtensions[]=ezoracle in site.ini.append.php
3. Run ./extension/ezoracle/bin/shell/ora-initialize.sh
4. Add to site.ini.append.php
