<AMAWSRDS ACTIVITY="delete_instance" INSTANCEID="text" SNAPSHOTID="text" SKIPSNAPSHOTID="yes/no" RESULTDATASET="text" ACCESSKEY="text" SECRETKEY="text (encrypted)" SERVICEURL="text" PROXYHOST="text" USERAGENT="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (encrypted)" MAXERRORRETRY="number" SIGNMETHOD="text" SIGNVERSION="number" />
Description
Deletes an existing RDS database instance and optionally populates a dataset with information about the deleted instance.
IMPORTANT: Automate Desktop's RDS activities
are performed using Amazon's Relational
Database Service engine, therefore, administering
Amazon RDS through Automate Desktop requires a valid Access Key ID and
Secret Access Key.
Practical usage
Used to delete a database instance that may no longer be needed or used.
NOTE: Once this activity
executes, the process cannot be stopped and the database instance will
no longer be accessible.
Parameters
Connection
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| Connection | --- | --- | --- | --- | Indicates
where Amazon Web Service user credentials and preferences should
originate from. This is a design mode parameter used only during
task construction and configuration, thus, comprises no markup.
The available options are:
|
Connection - Session
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| Session | Text | Yes, if Connection is set to Session | EC2Session1 | SESSION="RDSSession1" | The name of an existing session to attach this activity to. This parameter is active only if the Connection parameter is set to Session. The default session name is RDSSession1. |
Connection - Host > Credentials
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| Access key | Text | Yes, if Connection is set to Host | (Empty) | ACCESSKEY="022QF06E7MXBSH9DHM02" | A 20-character alphanumeric string that uniquely identifies the owner of the AWS service account, similar to a username. This key along with a corresponding secret access key forms a secure information set that AWS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
| Secret access key | Text | Yes, if Connection is set to Host | (Empty) | SECRETKEY="kWcrlUX5JEDGM/LtmEENI/aVmYvHNif5zB+d9+ct" | A 40-character string that serves the role as password to access the AWS service account. This along with an associated access key forms a secure information set that EC2 uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
Connection - Host > Advanced
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| User agent | Text | No | Automate | USERAGENT="Automate" | The name of the client or application initiating requests to AWS. The default value is Automate. |
| Maximum number of retries on error | Number | No | (Empty) | MAXERRORRETRY="4" | The total amount of times this activity should retry its request to the server before returning an error. Network components can generate errors anytime in the life of a request, thus, implementing retries can increase reliability. |
| Service URL | Text | No | (Empty) | SERVICEURL="https://rds.eu-west-1.amazonaws.com" | The URL that provides the service endpoint. To make the service call to a different region, you can pass the region-specific endpoint URL. For example, entering https://rds.us-west-1.amazonaws.com points to US West (Northern California) region. A complete list of EC2 regions, accompanying endpoints and valid protocols can be found below under Amazon RDS - Delete instance. |
| Proxy host | Text | No | (Empty) | PROXYHOST="proxy.host.com" | The hostname (for example, server.domain.com) or IP address (for example, xxx.xxx.xxx.xxx) of the proxy server to use when connecting to AWS. |
| Proxy port | Number | No | (Empty) | PROXYPORT="1028" | The port that should be used to connect to the proxy server. |
| Proxy username | Text | No | (Empty) | PROXYUSER="username" | The username that should be used to authenticate connection with the proxy server (if required). |
| Proxy password | Text | No | (Empty) | PROXYPWD="encrypted" | The password that should be used to authenticate connection with the proxy server (if required). |
| Signature method | Text | No | (Empty) | SIGNMETHOD="HmacSHA256" | The signature method to use for signing the request. This provides a valid hashing algorithm for signature calculation. Valid AWS signature methods are HmacSHA1 and HmacSHA256. |
| Signature version | Number | No | (Empty) | SIGNVERSION="2" | The signature version for signing the request. Valid AWS signature versions are 2 and 4. The difference with version 4 is that it allows you to sign your message using a key that is derived from your secret access key rather than using the secret access key itself. |
Instance
| Property | Type | Required | Default | Markup | Description |
|---|---|---|---|---|---|
| Instance identifier | Text | Yes | (Empty) | INSTANCEID="my-test-1" | The unique name/identifier of the RDS instance to delete. This identifier specifies a particular DB instance when interacting with the RDS API. |
| Final snapshot identifier (optional) | Text | No | (Empty) | SNAPSHOTID="mySnapshot" | The
name for the final DB Snapshot. A final DB snapshot is normally
created before it is deleted. This option is not permitted if the Skip Final Snapshot option is selected. |
| Skip final snapshot | Yes/No | No | No | SKIPSNAPSHOTID="yes" | If set to YES, specifies that no final DB snapshot should be made of the DB instance before it is deleted. Set to NO by default. |
| Create and populate dataset with instance information | Text | No | (Empty) | RESULTDATASET="myDataset" | The name of the dataset to create and populate with the RDS instance information. More information about the dataset fields that this activity creates can be found below under Datasets. |
