OracleSettings

Provides information that defines an Oracle endpoint.

Contents

AccessAlternateDirectly

Set this attribute to false in order to use the Binary Reader to capture change data for an Amazon RDS for Oracle as the source. This tells the DMS instance to not access redo logs through any specified path prefix replacement using direct file access.

Type: Boolean

Required: No

AdditionalArchivedLogDestId

Set this attribute with ArchivedLogDestId in a primary/ standby setup. This attribute is useful in the case of a switchover. In this case, Amazon 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 Amazon 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.

Type: Integer

Required: No

AddSupplementalLogging

Set this attribute to set up table-level supplemental logging for the Oracle database. This attribute enables PRIMARY KEY supplemental logging on all tables selected for a migration task.

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

Type: Boolean

Required: No

AllowSelectNestedTables

Set this attribute to true to enable replication of Oracle tables containing columns that are nested tables or defined types.

Type: Boolean

Required: No

ArchivedLogDestId

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.

Type: Integer

Required: No

ArchivedLogsOnly

When this field is set to Y, Amazon DMS only accesses the archived redo logs. If the archived redo logs are stored on Oracle ASM only, the Amazon DMS user account needs to be granted ASM privileges.

Type: Boolean

Required: No

AsmPassword

For an Oracle source endpoint, your Oracle Automatic Storage Management (ASM) password. You can set this value from the asm_user_password value. You set this value as part of the comma-separated value that you set to the Password request parameter when you create the endpoint to access transaction logs using Binary Reader. For more information, see Configuration for change data capture (CDC) on an Oracle source database.

Type: String

Required: No

AsmServer

For an Oracle source endpoint, your ASM server address. You can set this value from the asm_server value. You set asm_server as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database.

Type: String

Required: No

AsmUser

For an Oracle source endpoint, your ASM user name. You can set this value from the asm_user value. You set asm_user as part of the extra connection attribute string to access an Oracle server with Binary Reader that uses ASM. For more information, see Configuration for change data capture (CDC) on an Oracle source database.

Type: String

Required: No

CharLengthSemantics

Specifies whether the length of a character column is in bytes or in characters. To indicate that the character column length is in characters, set this attribute to CHAR. Otherwise, the character column length is in bytes.

Example: charLengthSemantics=CHAR;

Type: String

Valid Values: default | char | byte

Required: No

DatabaseName

Database name for the endpoint.

Type: String

Required: No

DirectPathNoLog

When set to true, this attribute helps to increase the commit rate on the Oracle target database by writing directly to tables and not writing a trail to database logs.

Type: Boolean

Required: No

DirectPathParallelLoad

When set to true, this attribute specifies a parallel load when useDirectPathFullLoad is set to Y. This attribute also only applies when you use the Amazon DMS parallel load feature. Note that the target table cannot have any constraints or indexes.

Type: Boolean

Required: No

EnableHomogenousTablespace

Set this attribute to enable homogenous tablespace replication and create existing tables or indexes under the same tablespace on the target.

Type: Boolean

Required: No

ExtraArchivedLogDestIds

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, Amazon DMS needs information about what destination to get archive redo logs from to read changes. Amazon 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 Amazon 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.

Type: Array of integers

Required: No

FailTasksOnLobTruncation

When set to true, this attribute causes a task to fail if the actual size of an LOB column is greater than the specified LobMaxSize.

If a task is set to limited LOB mode and this option is set to true, the task fails instead of truncating the LOB data.

Type: Boolean

Required: No

NumberDatatypeScale

Specifies the number scale. You can select a scale up to 38, or you can select FLOAT. By default, the NUMBER data type is converted to precision 38, scale 10.

Example: numberDataTypeScale=12

Type: Integer

Required: No
