DBMS_CLOUD_NOTIFICATION

The DBMS_CLOUD_NOTIFICATION package allows you to send messages or the output of a SQL query to a provider.

DBMS_CLOUD_NOTIFICATION Overview

This scenario describes setup and use of the DBMS_CLOUD_NOTIFICATION package.

The supported providers are: Email, Microsoft Teams, and Slack.

Installing DBMS_CLOUD Packages

The DBMS_CLOUD family of packages is not pre-installed or configured with Oracle database. You need to manually install the DBMS_CLOUD packages and also configure users or roles to use this package.

For information on installation and configuration with Oracle Database 19c, Release 19.30 and above, see Using the DBMS_CLOUD Family of Packages.

For installing the DBMS_CLOUD packages and configuring users or roles for Oracle Database 19c, Releases prior to 19.30, see the MOS-NOTE with Doc ID 2748362.1. Note that earlier releases provide limited DBMS_CLOUD functionality only.

Summary of DBMS_CLOUD_NOTIFICATION Subprograms

This table summarizes the subprograms included in the package.

Subprogram	Description
SEND_DATA Procedure	Send SQL query output to a provider.
SEND_MESSAGE Procedure	Send a text message to a provider.

SEND_DATA Procedure

The SEND_DATA procedure sends the results of the specified query to a provider.

Syntax

DBMS_CLOUD_NOTIFICATION.SEND_DATA(
       provider           IN  VARCHAR2,
       credential_name    IN  VARCHAR2,
       query              IN  CLOB,
       params             IN  CLOB
 );

Parameters

Parameter	Description
`provider`	Specifies the provider. Valid values are: '`email`', '`msteams`', and '`slack`' This parameter is mandatory.
`credential_name`	The name of the credential object to access the provider. For the email provider, the credential is the name of the credential of the SMTP approved sender that contains its username and password. For the msteams provider, the credential is the name of the credential. For the Slack provider, the credential's username must be `"SLACK_TOKEN"` and the `password` is the Slack Bot Token. This parameter is mandatory.
`query`	Specifies the SQL query to run. Results are sent to the provider. This parameter is mandatory.
`params`	Specifies specific parameters for the `provider` in JSON format. For the provider type `email`, the valid parameters are: `sender`. This specifies the Email ID of the approved sender in a `String` value. `smtp_host`. This specifies the SMTP host name in a `String` value. `subject`. This specifies the subject of the email in a `String` value The maximum size is 100 characters. `recipient`. This specifies the email IDs of recipients in a `String` value. Use a comma between email IDs when there are multiple recipients. `to_cc`. This specifies the email IDs that are receiving a CC of the email. It is a `String` value. Use a comma between email IDs when there are multiple CC recipients. `to_bcc`. This specifies the email IDs that are receiving a BCC of the email. It is a `String` value. Use a comma between email IDs when there are multiple BCC recipients. `message`. This specifies the message text in a `String` value. `type`. This specifies the output format in a `String` value as either CSV or JSON. `title`. This specifies the title of the attachment of SQL output in a `String` value. The title should only contain letters, digits, underscores, hyphens, or dots as characters in its value due to it being used to generate a file name. For the provider type `msteams`, the valid parameters are: `tenant`. This specifies the tenant ID in a `String` format. `team`. This specifies the team ID in a `String` format. `channel`. This specifies the channel ID in a `String` format. `title`. This specifies the title of the file in a `String` format. The maximum size is 50 characters. `type`. This specifies the output format in a `String` value. Valid values are CSV or JSON. For the provider type `slack`, the valid parameters are: `channel`. This specifies the Channel ID in a `String` value. The Channel ID is a unique ID for a channel and is different from the channel name. In Slack, when you view channel details you can find the Channel ID on the "About" tab. `type`. This specifies the output format in a `String` value. Valid values are CSV or JSON. This parameter is mandatory.

Usage Notes

Use the procedure DBMS_CLOUD.CREATE_CREDENTIAL(credential_name, username, password) to create the credential object.

See CREATE_CREDENTIAL Procedure for more information.
For the email provider, note the following:
- The user requires an SMTP connection endpoint for the Email Delivery server to obtain smtp_host. The user also requires an SMTP approved sender and its credentials to authenticate with the Email Delivery server to obtain the credential_name. The SMTP connection must be configured and the SMTP credentials must be generated and approved.
- The maximum message size supported when using DBMS_CLOUD_NOTIFICATION.SEND_DATA with the email provider is 32k bytes.
For the msteams provider, the user requires the Microsoft Teams App and a bot configured in it. The app needs to be published to the org and installed after obtaining approval from the admin from the admin center. The user also requires access for Files.ReadWrite.All and ChannelSettings.Read.All permission for Graph API from their Azure Portal. To generate the required token, the user requires bot_id in the username and bot_secret in the password.

The maximum file size supported when using DBMS_CLOUD_NOTIFICATION.SEND_DATA for Microsoft Teams is 4MB.
For the slack provider, the username value can be any valid string and the password is the Slack bot token.
