Creating ODM Schemas & Repository for ODM 11g R2

Before you can start using the Oracle Data Miner features that are now available in SQL Developer 3, there are a few steps you need to perform. This post will walk you through these steps and I have put together a video which goes into more detail. The video is available on my YouTube channel.

I have also created a view of this blog post that contains more details of topics covered. So check out the video.

Creating ODM Schemas & Repository video – YouTube

I will be posting more How To type videos over the coming weeks and months. Each video will focus in one one particular feature within the new Oracle Data Mining tool.

So following steps are necessary before you can start using the ODM tool

Set up of Oracle Data Miner tabs

To get the ODM tabs to display in SQL Developer, you need to go to the View menu and select the following from the Data Miner submenu:

  • Data Miner Connections
  • Workflow Jobs
  • Property Inspector

Create an ODM Schema

There are two main ways to create a Schema. The first and simplest way is to use SQL Developer. To do this you need to create a connection to SYS. Right
click on the Other Users option and select Create User.

The second option is to use SQL*Plus to create the user. Using both methods you need to grant Connect & Resource privileges to the user.

Create the Repository

Before you can start using Oracle Data Mining, you need to create an Oracle Data Miner Repository in the database. Again there are two ways to do this. The
simplest is to use the inbuilt functionality in SQL Developer. In the Oracle Data Miner Connections tab, double click on the ODM schema you have just
created. SQL Developer will check the database to see if the ODM Repository exists in the database. If it will create the repository for you. But you will
need to provide the SYS password.

The other way to create the repository is to run the installodmr.sql script that in available in the ‘datamining’ directory.

@installodmr.sql <default tablespace> <temp tablespace>

example:   @installodmr.sql USER TEMP

 

Create another ODM Schema

It is typical that you would need to have more than one schema for your data mining work. After creating the default Oracle schema, the next step is to grant
the schema the privileges to use the Data Mining Repository. This script is called

usergrants.sql <DM Schema>

example:    @usergrants.sql DMUSER

Hint: The schema name needs to be in upper case.

IMPORTANT: The last grant statement in the script may give an error. If this occurs then it is due to an invalid hidden character on the line. If you do a
cut and paste of the grant statement and execute this statement, everything should run fine.

If you want to demo data to be created for this new ODM schema then you need to run

@instdemodata.sql <DM Schema>

example:    @instdemodata.sql DMUSER

All of these scripts can be found in SQL developer directories
