Importing from Oracle using Zoho Databridge

If you have data in a local/hosted Oracle database, then you can easily import your data into Zoho Analytics using the Zoho Databridge. Zoho Analytics also allows you to connect data live from the Oracle database.

The Zoho Databridge bridges your local Oracle database and Zoho Analytics server to fetch data from your local /hosted  Oracle database. With this, you can also automate the import process to synchronize the data from your local /hosted Oracle database into Zoho Analytics at a periodic interval.

You can either import the data into Zoho Analytics or connect directly with the Oracle database server.

• Data Import: Data in the Oracle database will be imported and stored in Zoho Analytics. You can setup periodic schedules to fetch the latest data automatically from your Oracle database. Report loading time will be faster as the data is stored in Zoho Analytics.
• Live Connect: In this mode, data will not be fetched from the Oracle database and stored in Zoho Analytics. Instead for the reports that you create, Zoho Analytics will generate appropriate queries that will connect the required data live from the Oracle database to Zoho Analytics and show you the report. In this case, the loading time will directly depend on the performance of the Oracle database. The Live Connect option is exclusively available for paid plans and trials only.

This may happen due to various factors such as connectivity issues or privileges to access the protected data source. Refer to our Zoho Databridge Troubleshooting tip section to solve the specific issue you are facing. 

Live Connect [Beta]

1. How do I install Zoho Databridge?

You can easily install Zoho Databridge from the Zoho Analytics interface. Refer here to learn how.

2. How do I connect live with the Oracle database?

3. How can I edit the live connect setup?

5. How long does it take for me to visualize my data in Zoho Analytics?

As there is no data import process involved, the loading time depends upon the amount of data stored in your Oracle database and also the response time of your Oracle database.

6. Will the reports/dashboards query hit my database server every time I open it or can it be cached in Zoho Analytics?
(or) Can I store a cache of my data points in Zoho Analytics to get quick access to my views?

Zoho Analytics allows you to create a cache for the reports in your live connect database to reduce the query fetching time.

To enable cache for your live connect workspace, please follow the below steps:

1. From your Workspace Explorer, click Settings from the side menubar.
   
2. In the General - Workspace Settings page that opens, choose Yes for Enable Cache for this Workspace.
3. Provide Cache Refresh Interval in Minutes.
4. Click Save & Close.

A cache for the reports will be created for the Workspace.

7. Can I connect Views created in the Oracle database (apart from Tables) to Zoho Analytics?

Yes, you can connect with both Views and Tables created in the Oracle database to Zoho Analytics.

8. Will foreign keys defined between my tables in the Oracle database be linked in Zoho Analytics as well?

Yes. In case you have linked two or more tables in your Oracle database using foreign keys, they will be linked automatically using a Look-up column in Zoho Analytics as well.

9. I got an alert message "This view cannot be accessed due to some changes made in the table" while accessing my tables/reports in Zoho Analytics. What should I do?

This alert message will be displayed when Zoho Analytics is not able to access the information from the Oracle database. This could be because the tables/columns that you are trying to access in Zoho Analytics is deleted or renamed in Oracle database.

In this case, it is recommended that you remap the table/column. Refer to this presentation to know how to remap a table.

10. What is a Mismatch?

When you have created reports in Zoho Analytics over the tables or columns which no longer have a direct mapping in the Oracle database, it will be listed as a mismatch. 

So, ensure that the tables/columns in Zoho Analytics workspace and Oracle database match. The tables/columns that do not match will be listed in the Mismatch tab of the Local Database​ Connection Settings page. Refer the next question to know more about mismatch.

11. When do Mismatches occur and how to resolve them?

12. Can I connect new columns added in my Oracle database to Zoho Analytics?

Yes, you can connect the new columns that are added in your Oracle database to Zoho Analytics from the Local Database Connection Settings page. Refer to this presentation to know more.

13. Can I change the data type of the columns in Zoho Analytics?

No, you cannot change the data type of the columns in Zoho Analytics.

14. Can I import data from other data sources into the same workspace that I have used to connect with the Oracle database?

No, you cannot import data from other data sources into the same workspace that you have used to connect with the Oracle database.

15. Can I create Query Tables over the Oracle data?

No, you will not be able to create Query Tables if you have setup the workspace using the Oracle Live Connect option. This is because this option does not fetch and store the data locally in Zoho Analytics. If you wish to create Query Tables, you can create the required query as a view in the data source and connect the same with Zoho Analytics.

16. What happens when I delete or rename the database in the Oracle database?

When you delete or rename a database in the Oracle database, Zoho Analytics loses its connectivity with Oracle database. Thereafter, a warning message, as shown below, would be displayed. This error message will also be displayed if there are any connectivity issues or if your Oracle database credentials have expired.

For more information regarding the same, refer to the Edit Connection presentation.

17. How do I remove the Setup?

You have to delete the workspace in Zoho Analytics to remove the connection setup. 

To delete the workspace,

1. Log in to Zoho Analytics
2. Click the More Actions icon that appears on the mouse hover adjacent to the workspace name that you want to delete
3. Click the Delete Workspace option

18. What are the limitations of using the Oracle database Live Connect?

Given below are a few shortcomings that one might face while using the Oracle database​ Live Connect option.

• Data from your Oracle database will NOT be locally stored in Zoho Analytics. Zoho Analytics will generate appropriate queries to fetch the required data live from Oracle database and show you the report. Hence, the loading time will directly depend on the performance of the Oracle database server.
• Any changes such as column addition/deletion/renaming will not be mapped automatically. The user must manually map the updates made.
• Users cannot combine data from other data sources into the same workspace in which you have connected the Oracle database. 
• Users cannot create query tables.
• Users cannot change the data type of the columns in Zoho Analytics.
