# Importing transported tablespaces to your DB instance
Importing transported tablespaces

Use the procedure `rdsadmin.rdsadmin_transport_util.import_xtts_tablespaces` to restore tablespaces that you have previously exported from a source DB instance. In the transport phase, you back up your read-only tablespaces, export Data Pump metadata, transfer these files to your target DB instance, and then import the tablespaces. For more information, see [Phase 4: Transport the tablespaces](oracle-migrating-tts.md#oracle-migrating-tts.final-br-phase). 

## Syntax
Syntax

```
FUNCTION import_xtts_tablespaces(
    p_tablespace_list IN CLOB,
    p_directory_name  IN VARCHAR2,
    p_platform_id     IN NUMBER DEFAULT 13,
    p_parallel        IN INTEGER DEFAULT 0) RETURN VARCHAR2;
```

## Parameters
Parameters


****  

| Parameter name | Data type | Default | Required | Description | 
| --- | --- | --- | --- | --- | 
|  `p_tablespace_list`  |  `CLOB`  |  —  |  Yes  |  The list of tablespaces to import.  | 
|  `p_directory_name`  |  `VARCHAR2`  |  —  |  Yes  | The directory that contains the tablespace backups. | 
|  `p_platform_id`  |  `NUMBER`  |  `13`  |  No  |  Provide a platform ID that matches the one specified during the backup phase. To find a list of platforms, query `V$TRANSPORTABLE_PLATFORM`. The default platform is Linux x86 64-bit, which is little endian.  | 
|  `p_parallel`  |  `INTEGER`  |  `0`  |  No  |  The degree of parallelism. By default, parallelism is disabled.  | 

## Examples
Examples

The following example imports the tablespaces *TBS1*, *TBS2*, and *TBS3* from the directory *DATA\$1PUMP\$1DIR*. The source platform is AIX-Based Systems (64-bit), which has the platform ID of `6`. You can find the platform IDs by querying `V$TRANSPORTABLE_PLATFORM`.

```
VAR task_id CLOB

BEGIN
  :task_id:=rdsadmin.rdsadmin_transport_util.import_xtts_tablespaces(
        'TBS1,TBS2,TBS3',
        'DATA_PUMP_DIR',
        p_platform_id => 6);
END;
/

PRINT task_id
