describe-endpoints

Description

Returns information about the endpoints for your account in the current region.

See also: AWS API Documentation

describe-endpoints 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: Endpoints

Options

--filters (list)

Filters applied to the endpoints.

Valid filter names: endpoint-arn | endpoint-type | endpoint-id | engine-name

(structure)

Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.

Name -> (string)

The name of the filter as specified for a Describe* or similar operation.

Values -> (list)

The filter value, which can specify one or more values used to narrow the returned results.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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 .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

• json
• text
• table
• yaml
• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on
• off
• auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64
• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

ExtraConnectionAttributes -> (string)

Additional connection attributes used to connect to the endpoint.

Status -> (string)

The status of the endpoint.

KmsKeyId -> (string)

An KMS key identifier that is used to encrypt the connection parameters for the endpoint.

If you don’t specify a value for the KmsKeyId parameter, then DMS uses your default encryption key.

KMS creates the default encryption key for your Amazon Web Services account. Your Amazon Web Services account has a different default encryption key for each Amazon Web Services Region.

EndpointArn -> (string)

The Amazon Resource Name (ARN) string that uniquely identifies the endpoint.

CertificateArn -> (string)

The Amazon Resource Name (ARN) used for SSL connection to the endpoint.

SslMode -> (string)

The SSL mode used to connect to the endpoint. The default value is none .

ServiceAccessRoleArn -> (string)

The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

ExternalTableDefinition -> (string)

The external table definition.

ExternalId -> (string)

Value returned by a call to CreateEndpoint that can be used for cross-account validation. Use it on a subsequent call to CreateEndpoint to create the endpoint with a cross-account.

DynamoDbSettings -> (structure)

The settings for the DynamoDB target endpoint. For more information, see the DynamoDBSettings structure.

ServiceAccessRoleArn -> (string)

The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action.

S3Settings -> (structure)

The settings for the S3 target endpoint. For more information, see the S3Settings structure.

ServiceAccessRoleArn -> (string)

The Amazon Resource Name (ARN) used by the service to access the IAM role. The role must allow the iam:PassRole action. It is a required parameter that enables DMS to write and read objects from an S3 bucket.

ExternalTableDefinition -> (string)

Specifies how tables are defined in the S3 source files only.

CsvRowDelimiter -> (string)

The delimiter used to separate rows in the .csv file for both source and target. The default is a carriage return (\n ).

CsvDelimiter -> (string)

The delimiter used to separate columns in the .csv file for both source and target. The default is a comma.

BucketFolder -> (string)

An optional parameter to set a folder name in the S3 bucket. If provided, tables are created in the path `` bucketFolder /schema_name /table_name /`` . If this parameter isn’t specified, then the path used is `` schema_name /table_name /`` .

BucketName -> (string)

The name of the S3 bucket.

CompressionType -> (string)

An optional parameter to use GZIP to compress the target files. Set to GZIP to compress the target files. Either set this parameter to NONE (the default) or don’t use it to leave the files uncompressed. This parameter applies to both .csv and .parquet file formats.

EncryptionMode -> (string)

The type of server-side encryption that you want to use for your data. This encryption type is part of the endpoint settings or the extra connections attributes for Amazon S3. You can choose either SSE_S3 (the default) or SSE_KMS .

Note

For the ModifyEndpoint operation, you can change the existing value of the EncryptionMode parameter from SSE_KMS to SSE_S3 . But you can’t change the existing value from SSE_S3 to SSE_KMS .

To use SSE_S3 , you need an Identity and Access Management (IAM) role with permission to allow "arn:aws:s3:::dms-*" to use the following actions:

• s3:CreateBucket
• s3:ListBucket
• s3:DeleteBucket
• s3:GetBucketLocation
• s3:GetObject
• s3:PutObject
• s3:DeleteObject
• s3:GetObjectVersion
• s3:GetBucketPolicy
• s3:PutBucketPolicy
• s3:DeleteBucketPolicy

ServerSideEncryptionKmsKeyId -> (string)

If you are using SSE_KMS for the EncryptionMode , provide the KMS key ID. The key that you use needs an attached policy that enables Identity and Access Management (IAM) user permissions and allows use of the key.

Here is a CLI example: ``aws dms create-endpoint –endpoint-identifier value –endpoint-type target –engine-name s3 –s3-settings ServiceAccessRoleArn=*value* ,BucketFolder=*value* ,BucketName=*value* ,EncryptionMode=SSE_KMS,ServerSideEncryptionKmsKeyId=*value* ``

DataFormat -> (string)

The format of the data that you want to use for output. You can choose one of the following:

• csv : This is a row-based file format with comma-separated values (.csv).
• parquet : Apache Parquet (.parquet) is a columnar storage file format that features efficient compression and provides faster query response.

EncodingType -> (string)

The type of encoding you are using:

• RLE_DICTIONARY uses a combination of bit-packing and run-length encoding to store repeated values more efficiently. This is the default.
• PLAIN doesn’t use encoding at all. Values are stored as they are.
• PLAIN_DICTIONARY builds a dictionary of the values encountered in a given column. The dictionary is stored in a dictionary page for each column chunk.

DictPageSizeLimit -> (integer)

The maximum size of an encoded dictionary page of a column. If the dictionary page exceeds this, this column is stored using an encoding type of PLAIN . This parameter defaults to 1024 * 1024 bytes (1 MiB), the maximum size of a dictionary page before it reverts to PLAIN encoding. This size is used for .parquet file format only.

RowGroupLength -> (integer)

The number of rows in a row group. A smaller row group size provides faster reads. But as the number of row groups grows, the slower writes become. This parameter defaults to 10,000 rows. This number is used for .parquet file format only.

If you choose a value larger than the maximum, RowGroupLength is set to the max row group length in bytes (64 * 1024 * 1024).

DataPageSize -> (integer)

The size of one data page in bytes. This parameter defaults to 1024 * 1024 bytes (1 MiB). This number is used for .parquet file format only.

ParquetVersion -> (string)

The version of the Apache Parquet format that you want to use: parquet_1_0 (the default) or parquet_2_0 .

EnableStatistics -> (boolean)

A value that enables statistics for Parquet pages and row groups. Choose true to enable statistics, false to disable. Statistics include NULL , DISTINCT , MAX , and MIN values. This parameter defaults to true . This value is used for .parquet file format only.

IncludeOpForFullLoad -> (boolean)

A value that enables a full load to write INSERT operations to the comma-separated value (.csv) or .parquet output files only to indicate how the rows were added to the source database.

Note

DMS supports the IncludeOpForFullLoad parameter in versions 3.1.4 and later.

DMS supports the use of the .parquet files with the IncludeOpForFullLoad parameter in versions 3.4.7 and later.

For full load, records can only be inserted. By default (the false setting), no information is recorded in these output files for a full load to indicate that the rows were inserted at the source database. If IncludeOpForFullLoad is set to true or y , the INSERT is recorded as an I annotation in the first field of the .csv file. This allows the format of your target records from a full load to be consistent with the target records from a CDC load.

Note

This setting works together with the CdcInsertsOnly and the CdcInsertsAndUpdates parameters for output to .csv files only. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

CdcInsertsOnly -> (boolean)

A value that enables a change data capture (CDC) load to write only INSERT operations to .csv or columnar storage (.parquet) output files. By default (the false setting), the first field in a .csv or .parquet record contains the letter I (INSERT), U (UPDATE), or D (DELETE). These values indicate whether the row was inserted, updated, or deleted at the source database for a CDC load to the target.

If CdcInsertsOnly is set to true or y , only INSERTs from the source database are migrated to the .csv or .parquet file. For .csv format only, how these INSERTs are recorded depends on the value of IncludeOpForFullLoad . If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to I to indicate the INSERT operation at the source. If IncludeOpForFullLoad is set to false , every CDC record is written without a first field to indicate the INSERT operation at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

Note

DMS supports the interaction described preceding between the CdcInsertsOnly and IncludeOpForFullLoad parameters in versions 3.1.4 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can’t both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

TimestampColumnName -> (string)

A value that when nonblank causes DMS to add a column with timestamp information to the endpoint data for an Amazon S3 target.

Note

DMS supports the TimestampColumnName parameter in versions 3.1.4 and later.

DMS includes an additional STRING column in the .csv or .parquet object files of your migrated data when you set TimestampColumnName to a nonblank value.

For a full load, each row of this timestamp column contains a timestamp for when the data was transferred from the source to the target by DMS.

For a change data capture (CDC) load, each row of the timestamp column contains the timestamp for the commit of that row in the source database.

The string format for this timestamp column value is yyyy-MM-dd HH:mm:ss.SSSSSS . By default, the precision of this value is in microseconds. For a CDC load, the rounding of the precision depends on the commit timestamp supported by DMS for the source database.

When the AddColumnName parameter is set to true , DMS also includes a name for the timestamp column that you set with TimestampColumnName .

ParquetTimestampInMillisecond -> (boolean)

A value that specifies the precision of any TIMESTAMP column values that are written to an Amazon S3 object file in .parquet format.

Note

DMS supports the ParquetTimestampInMillisecond parameter in versions 3.1.4 and later.

When ParquetTimestampInMillisecond is set to true or y , DMS writes all TIMESTAMP columns in a .parquet formatted file with millisecond precision. Otherwise, DMS writes them with microsecond precision.

Currently, Amazon Athena and Glue can handle only millisecond precision for TIMESTAMP values. Set this parameter to true for S3 endpoint object files that are .parquet formatted only if you plan to query or process the data with Athena or Glue.

Note

DMS writes any TIMESTAMP column values written to an S3 file in .csv format with microsecond precision.

Setting ParquetTimestampInMillisecond has no effect on the string format of the timestamp column value that is inserted by setting the TimestampColumnName parameter.

CdcInsertsAndUpdates -> (boolean)

A value that enables a change data capture (CDC) load to write INSERT and UPDATE operations to .csv or .parquet (columnar storage) output files. The default setting is false , but when CdcInsertsAndUpdates is set to true or y , only INSERTs and UPDATEs from the source database are migrated to the .csv or .parquet file.

Warning

DMS supports the use of the .parquet files in versions 3.4.7 and later.

How these INSERTs and UPDATEs are recorded depends on the value of the IncludeOpForFullLoad parameter. If IncludeOpForFullLoad is set to true , the first field of every CDC record is set to either I or U to indicate INSERT and UPDATE operations at the source. But if IncludeOpForFullLoad is set to false , CDC records are written without an indication of INSERT or UPDATE operations at the source. For more information about how these settings work together, see Indicating Source DB Operations in Migrated S3 Data in the Database Migration Service User Guide. .

Note

DMS supports the use of the CdcInsertsAndUpdates parameter in versions 3.3.1 and later.

CdcInsertsOnly and CdcInsertsAndUpdates can’t both be set to true for the same endpoint. Set either CdcInsertsOnly or CdcInsertsAndUpdates to true for the same endpoint, but not both.

DatePartitionEnabled -> (boolean)

When set to true , this parameter partitions S3 bucket folders based on transaction commit dates. The default value is false . For more information about date-based folder partitioning, see Using date-based folder partitioning .

DatePartitionSequence -> (string)

Identifies the sequence of the date format to use during folder partitioning. The default value is YYYYMMDD . Use this parameter when DatePartitionedEnabled is set to true .

DatePartitionDelimiter -> (string)

Specifies a date separating delimiter to use during folder partitioning. The default value is SLASH . Use this parameter when DatePartitionedEnabled is set to true .

UseCsvNoSupValue -> (boolean)

This setting applies if the S3 output files during a change data capture (CDC) load are written in .csv format. If set to true for columns not included in the supplemental log, DMS uses the value specified by ` CsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CsvNoSupValue`__ . If not set or set to false , DMS uses the null value for these columns.

Note

This setting is supported in DMS versions 3.4.1 and later.

CsvNoSupValue -> (string)

This setting only applies if your Amazon S3 output files during a change data capture (CDC) load are written in .csv format. If ` UseCsvNoSupValue https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-UseCsvNoSupValue`__ is set to true, specify a string value that you want DMS to use for all columns not included in the supplemental log. If you do not specify a string value, DMS uses the null value for these columns regardless of the UseCsvNoSupValue setting.

Note

This setting is supported in DMS versions 3.4.1 and later.

PreserveTransactions -> (boolean)

If set to true , DMS saves the transaction order for a change data capture (CDC) load on the Amazon S3 target specified by ` CdcPath https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-CdcPath`__ . For more information, see Capturing data changes (CDC) including transaction order on the S3 target .

Note

This setting is supported in DMS versions 3.4.2 and later.

CdcPath -> (string)

Specifies the folder path of CDC files. For an S3 source, this setting is required if a task captures change data; otherwise, it’s optional. If CdcPath is set, DMS reads CDC files from this path and replicates the data changes to the target endpoint. For an S3 target if you set ` PreserveTransactions https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-PreserveTransactions`__ to true , DMS verifies that you have set this parameter to a folder path on your S3 target where DMS can save the transaction order for the CDC load. DMS creates this CDC folder path in either your S3 target working directory or the S3 target location specified by ` BucketFolder https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketFolder`__ and ` BucketName https://docs.aws.amazon.com/dms/latest/APIReference/API_S3Settings.html#DMS-Type-S3Settings-BucketName`__ .

For example, if you specify CdcPath as MyChangedData , and you specify BucketName as MyTargetBucket but do not specify BucketFolder , DMS creates the CDC folder path following: MyTargetBucket/MyChangedData .

If you specify the same CdcPath , and you specify BucketName as MyTargetBucket and BucketFolder as MyTargetData , DMS creates the CDC folder path following: MyTargetBucket/MyTargetData/MyChangedData .

For more information on CDC including transaction order on an S3 target, see Capturing data changes (CDC) including transaction order on the S3 target .

Note

This setting is supported in DMS versions 3.4.2 and later.

UseTaskStartTimeForFullLoadTimestamp -> (boolean)

When set to true, this parameter uses the task start time as the timestamp column value instead of the time data is written to target. For full load, when useTaskStartTimeForFullLoadTimestamp is set to true , each row of the timestamp column contains the task start time. For CDC loads, each row of the timestamp column contains the transaction commit time.

When useTaskStartTimeForFullLoadTimestamp is set to false , the full load timestamp in the timestamp column increments with the time data arrives at the target.

CannedAclForObjects -> (string)

A value that enables DMS to specify a predefined (canned) access control list for objects created in an Amazon S3 bucket as .csv or .parquet files. For more information about Amazon S3 canned ACLs, see Canned ACL in the Amazon S3 Developer Guide.

The default value is NONE. Valid values include NONE, PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE, AUTHENTICATED_READ, AWS_EXEC_READ, BUCKET_OWNER_READ, and BUCKET_OWNER_FULL_CONTROL.

AddColumnName -> (boolean)

An optional parameter that, when set to true or y , you can use to add column name information to the .csv output file.

The default value is false . Valid values are true , false , y , and n .

CdcMaxBatchInterval -> (integer)

Maximum length of the interval, defined in seconds, after which to output a file to Amazon S3.

When CdcMaxBatchInterval and CdcMinFileSize are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

The default value is 60 seconds.

CdcMinFileSize -> (integer)

Minimum file size, defined in kilobytes, to reach for a file output to Amazon S3.

When CdcMinFileSize and CdcMaxBatchInterval are both specified, the file write is triggered by whichever parameter condition is met first within an DMS CloudFormation template.

The default value is 32 MB.

CsvNullValue -> (string)

An optional parameter that specifies how DMS treats null values. While handling the null value, you can use this parameter to pass a user-defined string as null when writing to the target. For example, when target columns are nullable, you can use this option to differentiate between the empty string value and the null value. So, if you set this parameter value to the empty string (”” or ‘’), DMS treats the empty string as the null value instead of NULL .

The default value is NULL . Valid values include any valid string.

IgnoreHeaderRows -> (integer)

When this value is set to 1, DMS ignores the first row header in a .csv file. A value of 1 turns on the feature; a value of 0 turns off the feature.

The default is 0.

MaxFileSize -> (integer)

A value that specifies the maximum size (in KB) of any .csv file to be created while migrating to an S3 target during full load.

The default value is 1,048,576 KB (1 GB). Valid values include 1 to 1,048,576.

Rfc4180 -> (boolean)

For an S3 source, when this value is set to true or y , each leading double quotation mark has to be followed by an ending double quotation mark. This formatting complies with RFC 4180. When this value is set to false or n , string literals are copied to the target as is. In this case, a delimiter (row or column) signals the end of the field. Thus, you can’t use a delimiter as part of the string, because it signals the end of the value.

For an S3 target, an optional parameter used to set behavior to comply with RFC 4180 for data migrated to Amazon S3 using .csv file format only. When this value is set to true or y using Amazon S3 as a target, if the data has quotation marks or newline characters in it, DMS encloses the entire column with an additional pair of double quotation marks (“). Every quotation mark within the data is repeated twice.

The default value is true . Valid values include true , false , y , and n .

DatePartitionTimezone -> (string)

When creating an S3 target endpoint, set DatePartitionTimezone to convert the current UTC time into a specified time zone. The conversion occurs when a date partition folder is created and a CDC filename is generated. The time zone format is Area/Location. Use this parameter when DatePartitionedEnabled is set to true , as shown in the following example.

s3-settings='{"DatePartitionEnabled": true, "DatePartitionSequence": "YYYYMMDDHH", "DatePartitionDelimiter": "SLASH", "DatePartitionTimezone":"*Asia/Seoul* ", "BucketName": "dms-nattarat-test"}'

AddTrailingPaddingCharacter -> (boolean)

Cleans and recreates table metadata information on the replication instance when a mismatch occurs. For example, in a situation where running an alter DDL on the table could result in different information about the table cached in the replication instance.

DatabaseName -> (string)

Database name for the endpoint. For a MySQL source or target endpoint, don’t explicitly specify the database using the DatabaseName request parameter on either the CreateEndpoint or ModifyEndpoint API call. Specifying DatabaseName when you create or modify a MySQL endpoint replicates all the task tables to this single database. For MySQL endpoints, you specify the database only when you specify the schema in the table-mapping rules of the DMS task.

If you use this option, you still need to enable database-level supplemental logging.

ArchivedLogDestId -> (integer)

Specifies the ID of the destination for the archived redo logs. This value should be the same as a number in the dest_id column of the v$archived_log view. If you work with an additional redo log destination, use the AdditionalArchivedLogDestId option to specify the additional destination ID. Doing this improves performance by ensuring that the correct logs are accessed from the outset.

AdditionalArchivedLogDestId -> (integer)

Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, DMS needs to know which destination to get archive redo logs from to read changes. This need arises because the previous primary instance is now a standby instance after switchover.

Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless necessary. For additional information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User’s Guide .

ExtraArchivedLogDestIds -> (list)

Specifies the IDs of one more destinations for one or more archived redo logs. These IDs are the values of the dest_id column in the v$archived_log view. Use this setting with the archivedLogDestId extra connection attribute in a primary-to-single setup or a primary-to-multiple-standby setup.

This setting is useful in a switchover when you use an Oracle Data Guard database as a source. In this case, DMS needs information about what destination to get archive redo logs from to read changes. DMS needs this because after the switchover the previous primary is a standby instance. For example, in a primary-to-single standby setup you might apply the following settings.

archivedLogDestId=1; ExtraArchivedLogDestIds=[2]

In a primary-to-multiple-standby setup, you might apply the following settings.

archivedLogDestId=1; ExtraArchivedLogDestIds=[2,3,4]

Although DMS supports the use of the Oracle RESETLOGS option to open the database, never use RESETLOGS unless it’s necessary. For more information about RESETLOGS , see RMAN Data Repair Concepts in the Oracle Database Backup and Recovery User’s Guide .

ReadBackupOnly -> (boolean)

When this attribute is set to Y , DMS only reads changes from transaction log backups and doesn’t read from the active transaction log file during ongoing replication. Setting this parameter to Y enables you to control active transaction log file growth during full load and ongoing replication tasks. However, it can add some source latency to ongoing replication.

SafeguardPolicy -> (string)

Use this attribute to minimize the need to access the backup log and enable DMS to prevent truncation using one of the following two methods.

Start transactions in the database: This is the default method. When this method is used, DMS prevents TLOG truncation by mimicking a transaction in the database. As long as such a transaction is open, changes that appear after the transaction started aren’t truncated. If you need Microsoft Replication to be enabled in your database, then you must choose this method.

Exclusively use sp_repldone within a single task : When this method is used, DMS reads the changes and then uses sp_repldone to mark the TLOG transactions as ready for truncation. Although this method doesn’t involve any transactional activities, it can only be used when Microsoft Replication isn’t running. Also, when using this method, only one DMS task can access the database at any given time. Therefore, if you need to run parallel DMS tasks against the same database, use the default method.
