Description
Modifies a DB 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 alter a DB instance, such as when upgrading to a larger DB instance class. Note that once this activity starts, the process cannot be stopped, and the DB instance is unavailable until a reboot is completed.
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 RDS endpoints and regions . |
| 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
user-supplied unique name for the RDS instance to modify. This
is the unique key that identifies a DB Instance. Note that the
DB instance identifier must be unique for that customer in an
AWS region. If the name is not in lowercase characters, it will
be converted (for example, my-test-1). Certain constraints are as follows:
|
| Instance type | Text (Options) | Yes | (Empty) |
|
The
type of RDS Instance to modify. The available DB instance classes
are:
|
| Master password | Text | Yes | (Empty) | MASTERPWD="AM1sTPOFuKG75M=aME" | The master password for the instance. Mainly the password used to log into MySQL. |
| Port | Number | Yes | 3306 | Port="2400" | The RDS Instance's endpoint port. If this field is left blank (recommended), the default port for MySQL (3306) will be used. |
| Size (GBs) | Number | Yes | 5 | Size="6" | The size of the RDS Instance in GB that's allocated for storage. Valid Range: 5-1024 GB. |
| Security group | Text | No | (Empty) | SECURITYGROUP="myGroup" | The
name of the Amazon RDS security group. NOTE:
If unspecified, the default security group will be specified.
If it does not exist, it will be created for you. You can also
select multiple security groups. |
| Parameter group name | Text | No | (Empty) | PARAMGROUP="myParamGroup" | The
parameter group name. This is the customer-specified description
for this DB parameter group. NOTE:
If unspecified, the 'default.mysql5.1' parameter group will be
used. If it does not exist, it will be created for you. You
can only specify one RDS parameter group. |
| Backup retention period | Number | No | (Empty) | BACKUPPERIOD="2" | Specifies
the desired length of your retention period in number of days. AWS performs regular backups of the RDS Instance. For typical workloads, you should be able to restore your database to any point in time within your retention period, up to the last five minutes. |
| Preferred backup window | Date | No | (Empty) | BACKUPWINDOW="01:00-03:00" | Specifies a 2-hour window (GMT time-zone) for backups (HH:MM-HH:MM). If this field is left blank, the default window will be used (03:00-05:00). AWS will automatically perform a daily backup of your database during your predefined backup window. |
| Preferred maintenance window | Date | No | (Empty) | MAINTENANCEWINDOW="Sun:5:00-Sun:9:00" | Specifies a 4-hour window (GMT time-zone) during non peak time that's ideal for maintenance purposes (Example: Day:HH:Mmddyyyy:MM) If this field is left blank, the default window will be used (Sun:05:00-Sun:09:00). |
| Apply immediately | Yes/No | No | No | APPLYFAST="yes" | If set to YES, changes will take place immediately. Default value is set to NO. |
| Create and populate dataset with RDS instance information | Text | No | (Empty) | RESULTDATASET="myDataset" | The name of the dataset to create and populate with information regarding the RDS instance that was modified. More information regarding the individual fields this dataset creates can be found below under Datasets. |
