# Dropping tempfiles on a read replica
<a name="Appendix.Oracle.CommonDBATasks.dropping-tempfiles-replica"></a>

You can't drop an existing temporary tablespace on a read replica. You can change the tempfile storage on a read replica from Amazon EBS to the instance store, or from the instance store to Amazon EBS. To achieve these goals, do the following:

1. Drop the current tempfiles in the temporary tablespace on the read replica.

1. Create new tempfiles on different storage.

To drop the tempfiles, use the Amazon RDS procedure `rdsadmin.rdsadmin_util. drop_replica_tempfiles`. You can use this procedure only on read replicas. The `drop_replica_tempfiles` procedure has the following parameters.


****  

| Parameter name | Data type | Default | Required | Description | 
| --- | --- | --- | --- | --- | 
|  `p_tablespace_name`  |  varchar  |  —  |  Yes  |  The name of the temporary tablespace on your read replica.  | 

Assume that a temporary tablespace named *temp01* resides in the instance store on your read replica. Drop all tempfiles in this tablespace by running the following command.

```
EXEC rdsadmin.rdsadmin_util.drop_replica_tempfiles(p_tablespace_name => 'temp01');
```
