get-relational-database-parameters

Description

Returns all of the runtime parameters offered by the underlying database software, or engine, for a specific database in Amazon Lightsail.

In addition to the parameter names and values, this operation returns other information about each parameter. This information includes whether changes require a reboot, whether the parameter is modifiable, the allowed values, and the data types.

See 'aws help' for descriptions of global parameters.

get-relational-database-parameters is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: parameters

Synopsis

  get-relational-database-parameters
--relational-database-name <value>
[--cli-input-json <value>]
[--starting-token <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--relational-database-name (string)

The name of your database for which to get parameters.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To get parameters for a relational database

The following get-relational-database-parameters example returns information about all of the available parameters for the specified relational database.

aws lightsail get-relational-database-parameters \
    --relational-database-name Database-1

(structure)

Describes the parameters of a database.

allowedValues -> (string)

Specifies the valid range of values for the parameter.

applyMethod -> (string)

Indicates when parameter updates are applied.

Can be immediate or pending-reboot .

applyType -> (string)

Specifies the engine-specific parameter type.

dataType -> (string)

Specifies the valid data type for the parameter.

description -> (string)

Provides a description of the parameter.

isModifiable -> (boolean)

A Boolean value indicating whether the parameter can be modified.

parameterName -> (string)

Specifies the name of the parameter.

parameterValue -> (string)

Specifies the value of the parameter.

nextPageToken -> (string)

The token to advance to the next page of resutls from your request.

A next page token is not returned if there are no more results to display.

To get the next page of results, perform another GetRelationalDatabaseParameters request and specify the next page token using the pageToken parameter.
