Step 3: Test Connectivity to the Oracle DB Instance and Create the Sample Schema

After the CloudFormation stack has been created, test the connection to the Oracle DB instance by using SQL Workbench/J and then create the HR sample schema.

To test the connection to your Oracle DB instance using SQL Workbench/J and create the sample schema

  1. In SQL Workbench/J, choose File, then choose Connect window. Create a new connection profile using the following information.

    For This Parameter Do This

    New profile name

    Type RDSOracleConnection.

    Driver

    Choose Oracle (oracle.jdbc.OracleDriver).

    URL

    Use the OracleJDBCConnectionString value you recorded when you examined the output details of the DMSdemo stack in a previous step.

    Username

    Type oraadmin.

    Password

    Type oraadmin123.

  2. Test the connection by choosing Test. Choose OK to close the dialog box, then choose OK to create the connection profile.

    Note

    If your connection is unsuccessful, ensure that the IP address you assigned when creating the CloudFormation template is the one you are attempting to connect from. This issue is the most common one when trying to connect to an instance.

  3. Create the SH schema you will use for migration using a custom script. The SQL script provided by AWS is located https://dms-sbs.s3.amazonaws.com/Oraclesalesstarschema.sql.

    1. Open the provided SQL script in a text editor. Copy the entire script.

    2. In SQL Workbench/J, paste the SQL script in the Default.wksp window showing Statement 1.

    3. Choose SQL, then choose Execute All.

  4. Verify the object types and count in SH Schema were created successfully by running the following SQL query.

    Copy
    Select OBJECT_TYPE, COUNT(*) from dba_OBJECTS where owner='SH' GROUP BY OBJECT_TYPE;

    The results of this query should be similar to the following.

    Copy
    OBJECT_TYPE | COUNT(*) ----------------+--------- INDEX PARTITION | 40 TABLE PARTITION | 8 TABLE | 5 INDEX | 15
  5. Verify the total number of tables and number of rows for each table by running the following SQL query.

    Copy
    Select table_name, num_rows from dba_tables where owner='SH' order by 1;

    The results of this query should be similar to the following.

    Copy
    TABLE_NAME | NUM_ROWS -----------+--------- CHANNELS | 5 CUSTOMERS | 8 PRODUCTS | 66 PROMOTIONS | 503 SALES | 553
  6. Verify the integrity in tables. Check the number of sales made in different channels by running the following SQL query.

    Copy
    Select b.channel_desc,count(*) from SH.SALES a,SH.CHANNELS b where a.channel_id=b.channel_id group by b.channel_desc order by 1;

    The results of this query should be similar to the following.

    Copy
    CHANNEL_DESC | COUNT(*) -------------+--------- Direct Sales | 710 Internet | 52 Partners | 344

Note

The preceding examples are representative of validation queries. When you perform actual migrations, you should develop similar queries to validate the schema and the data integrity.
