Oracle Management Agent for Enterprise Manager Cloud Control
Oracle Enterprise Manager (OEM) Management Agent is a software component that monitors targets running on hosts and communicates that information to the middle-tier Oracle Management Service (OMS). For more information, see Overview of Oracle Enterprise Manager cloud control 12c and Overview of Oracle Enterprise Manager cloud control 13c in the Oracle documentation.
Amazon RDS supports Management Agent through the use of the OEM_AGENT option. Management Agent requires an Amazon RDS DB instance running any of the following releases:
Oracle Database 19c (19.0.0.0) using the non-CDB architecture
Oracle Database 12c Release 2 (12.2.0.1)
Oracle Database 12c Release 1 (12.1.0.2)
Amazon RDS supports Management Agent for the following versions of OEM:
Oracle Enterprise Manager Cloud Control for 13c
Oracle Enterprise Manager Cloud Control for 12c
Prerequisites for Management Agent
Limitations for management agent, option settings for management agent, adding the management agent option, using the management agent, modifying management agent settings, performing database tasks with the management agent, removing the management agent option.
To use Management Agent, ensure that you meet the following prerequisites.
General prerequisites
Following are general prerequisites for using Management Agent:
You need an Oracle Management Service (OMS) that is configured to connect to your Amazon RDS DB instance.
In most cases, you must configure your VPC to allow connections from OMS to your DB instance. If you aren't familiar with Amazon Virtual Private Cloud (Amazon VPC), we recommend that you complete the steps in Tutorial: Create a VPC for use with a DB instance (IPv4 only) before continuing.
Management Agent version 13.5.0.0.v1 requires OMS version 13.5.0.0 or later.
Management Agent version 13.4.0.9.v1 requires OMS version 13.4.0.9 or later and patch 32198287.
Ensure that you have sufficient storage space for your OEM release:
At least 8.5 GiB for OEM 13c Release 5
At least 8.5 GiB for OEM 13c Release 4
At least 8.5 GiB for OEM 13c Release 3
At least 5.5 GiB for OEM 13c Release 2
At least 4.5 GiB OEM 13c Release 1
At least 2.5 GiB for OEM 12c
If you are using Management Agent versions OEM_AGENT 13.2.0.0.v3 and 13.3.0.0.v2 , and if you want to use TCPS connectivity, follow the instructions in Configuring third party CA certificates for communication with target databases in the Oracle documentation. Also, update the JDK on your OMS by following the instructions in the Oracle document with the Oracle Doc ID 2241358.1. This step ensures that OMS supports all the cipher suites that the database supports.
TCPS connectivity between the Management Agent and the DB instance is supported for Management Agent OEM_AGENT 13.2.0.0.v3 , 13.3.0.0.v2 , 13.4.0.9.v1 , and higher versions.
Oracle Database release prerequisites
Following are the supported Oracle Database versions for each Management Agent version.
Following are prerequisites for different database versions:
For an Amazon RDS DB instance running Oracle Database 19c (19.0.0.0), the minimum AGENT_VERSION is 13.1.0.0.v1.
For an Amazon RDS DB instance running Oracle Database Release 2 (12.2.0.1) or lower, meet the following requirements:
For OMS 13c Release 2 with Oracle patch 25163555 applied, use OEM Agent 13.2.0.0.v2 or later.
Use OMSPatcher to apply the patch.
For unpatched OMS 13c Release 2, use OEM Agent 13.2.0.0.v1.
Use OMSPatcher to apply patches.
OMS host communication prerequisites
Make sure that your OMS host and your Amazon RDS DB instance can communicate. Do the following:
To connect from the Management Agent to your OMS, if your OMS is behind a firewall, add the IP addresses of your DB instances to your OMS.
Make sure the firewall for the OMS allows traffic from both the DB listener port (default 1521) and the OEM Agent port (default 3872), originating from the IP address of the DB instance.
To connect from your OMS to the Management Agent, if your OMS has a publicly resolvable host name, add the OMS address to a security group. Your security group must have inbound rules that allow access to the DB listener port and the Management Agent port. For an example of creating a security and adding inbound rules, see Tutorial: Create a VPC for use with a DB instance (IPv4 only) .
To connect from your OMS to the Management Agent, if your OMS doesn't have a publicly resolvable host name, use one of the following:
If your OMS is hosted on an Amazon Elastic Compute Cloud (Amazon EC2) instance in a private VPC, you can set up VPC peering to connect from OMS to Management Agent. For more information, see A DB instance in a VPC accessed by an EC2 instance in a different VPC .
If your OMS is hosted on-premises, you can set up a VPN connection to allow access from OMS to Management Agent. For more information, see A DB instance in a VPC accessed by a client application through the internet or VPN connections .
Following are some limitations to using Management Agent:
Administrative tasks such as job execution and database patching, that require host credentials, aren't supported.
Host metrics and the process list aren't guaranteed to reflect the actual system state. Thus, you shouldn't use OEM to monitor the root file system or mount point file system. For more information about monitoring the operating system, see Monitoring OS metrics with Enhanced Monitoring .
Autodiscovery isn't supported. You must manually add database targets.
OMS module availability depends on your database edition. For example, the database performance diagnosis and tuning module is only available for Oracle Database Enterprise Edition.
Management Agent consumes additional memory and computing resources. If you experience performance problems after enabling the OEM_AGENT option, we recommend that you scale up to a larger DB instance class. For more information, see DB instance classes and Modifying an Amazon RDS DB instance .
The user running the OEM_AGENT on the Amazon RDS host doesn't have operating system access to the alert log. Thus, you can't collect metrics for DB Alert Log and DB Alert Log Error Status in OEM.
Amazon RDS supports the following settings for the Management Agent option.
The following table lists the TLS cipher suites that the Management Agent option supports.
The general process for adding the Management Agent option to a DB instance is the following:
Create a new option group, or copy or modify an existing option group.
Add the option to the option group.
Associate the option group with the DB instance.
If you encounter errors, check My Oracle Support documents for information about resolving specific problems.
After you add the Management Agent option, you don't need to restart your DB instance. As soon as the option group is active, the OEM Agent is active.
If your OMS host is using an untrusted third-party certificate, Amazon RDS returns the following error.
If this error is returned, the Management Agent option isn't enabled until the problem is corrected. For information about correcting the problem, see the My Oracle Support document 2202569.1 .
To add the Management Agent option to a DB instance
Determine the option group you want to use. You can create a new option group or use an existing option group. If you want to use an existing option group, skip to the next step. Otherwise, create a custom DB option group with the following settings:
For Engine choose the oracle edition for your DB instance.
For Major engine version choose the version of your DB instance.
For more information, see Creating an option group .
Add the OEM_AGENT option to the option group, and configure the option settings. For more information about adding options, see Adding an option to an option group . For more information about each setting, see Option settings for Management Agent .
Apply the option group to a new or existing DB instance:
For a new DB instance, you apply the option group when you launch the instance. For more information, see Creating an Amazon RDS DB instance .
For an existing DB instance, you apply the option group by modifying the instance and attaching the new option group. For more information, see Modifying an Amazon RDS DB instance .
The following example uses the AWS CLI add-option-to-option-group command to add the OEM_AGENT option to an option group called myoptiongroup .
For Linux, macOS, or Unix:
For Windows:
After you enable the Management Agent option, take the following steps to begin using it.
To use the Management Agent
Unlock and reset the DBSNMP account credential. Do this by running the following code on your target database on your DB instance and using your master user account.
Add your targets to the OMS console manually:
In your OMS console, choose Setup , Add Target , Add Targets Manually .
Choose Add Targets Declaratively by Specifying Target Monitoring Properties .
For Target Type , choose Database Instance .
For Monitoring Agent , choose the agent with the identifier that is the same as your RDS DB instance identifier.
Choose Add Manually .
Enter the endpoint for the Amazon RDS DB instance, or choose it from the host name list. Make sure that the specified host name matches the endpoint of the Amazon RDS DB instance.
For information about finding the endpoint for your Amazon RDS DB instance, see Finding the endpoint of your Oracle DB instance .
Specify the following database properties:
For Target name , enter a name.
For Database system name , enter a name.
For Monitor username , enter dbsnmp .
For Monitor password , enter the password from step 1.
For Role , enter normal .
For Oracle home path , enter /oracle .
For Listener Machine name , the agent identifier already appears.
For Port , enter the database port. The RDS default port is 1521.
For Database name , enter the name of your database.
Choose Test Connection .
Choose Next . The target database appears in your list of monitored resources.
After you enable the Management Agent, you can modify settings for the option. For more information about how to modify option settings, see Modifying an option setting . For more information about each setting, see Option settings for Management Agent .
You can use Amazon RDS procedures to run certain EMCTL commands on the Management Agent. By running these procedures, you can do the tasks listed following.
Tasks are executed asynchronously.
Getting the status of the Management Agent
Restarting the management agent, listing the targets monitored by the management agent, listing the collection threads monitored by the management agent, clearing the management agent state, making the management agent upload its oms, pinging the oms, viewing the status of an ongoing task.
To get the status of the Management Agent, run the Amazon RDS procedure rdsadmin.rdsadmin_oem_agent_tasks.get_status_oem_agent . This procedure is equivalent to the emctl status agent command.

Amazon S3 integration
You can transfer files between your RDS for Oracle DB instance and an Amazon S3 bucket. You can use Amazon S3 integration with Oracle Database features such as Oracle Data Pump. For example, you can download Data Pump files from Amazon S3 to your RDS for Oracle DB instance. For more information, see Importing data into Oracle on Amazon RDS .
Note Your DB instance and your Amazon S3 bucket must be in the same AWS Region.
Configuring IAM permissions for RDS for Oracle integration with Amazon S3
Adding the amazon s3 integration option, transferring files between amazon rds for oracle and an amazon s3 bucket, removing the amazon s3 integration option.
For RDS for Oracle to integrate with Amazon S3, your DB instance must have access to an Amazon S3 bucket. The Amazon VPC used by your DB instance doesn't need to provide access to the Amazon S3 endpoints.
RDS for Oracle supports uploading files from a DB instance in one account to an Amazon S3 bucket in a different account. Where additional steps are required, they are noted in the following sections.
Step 1: Create an IAM policy for your Amazon RDS role
Step 2: (optional) create an iam policy for your amazon s3 bucket, step 3: create an iam role for your db instance and attach your policy, step 4: associate your iam role with your rds for oracle db instance.
In this step, you create an AWS Identity and Access Management (IAM) policy with the permissions required to transfer files from your Amazon S3 bucket to your RDS DB instance.
To create the policy, make sure you have the following:
- The Amazon Resource Name (ARN) for your bucket
- The ARN for your AWS KMS key, if your bucket uses SSE-KMS or SSE-S3 encryption Note An Oracle DB instance can't access Amazon S3 buckets encrypted with SSE-C.
For more information, see Protecting data using server-side encryption in the Amazon Simple Storage Service User Guide .
To create an IAM policy to allow Amazon RDS access to an Amazon S3 bucket
Open the IAM Management Console .
Under Access management , choose Policies .
Choose Create Policy .
On the Visual editor tab, choose Choose a service , and then choose S3 .
For Actions , choose Expand all , and then choose the bucket permissions and object permissions required to transfer files from an Amazon S3 bucket to Amazon RDS. For example, do the following:
- Expand List , and then select ListBucket .
- Expand Read , and then select GetObject .
- Expand Write , and then select PutObject and DeleteObject .
- Expand Permissions management , and then select PutObjectAcl . This permission is necessary if you plan to upload files to a bucket owned by a different account, and this account needs full control of the bucket contents.
Object permissions are permissions for object operations in Amazon S3. You must grant them for objects in a bucket, not the bucket itself. For more information, see Permissions for object operations .
Choose Resources , and choose Add ARN for bucket .
In the Add ARN(s) dialog box, provide the details about your resource, and choose Add .
Specify the Amazon S3 bucket to allow access to. For instance, to allow Amazon RDS to access the Amazon S3 bucket named example-bucket , set the ARN value to arn:aws:s3:::example-bucket .
If the object resource is listed, choose Add ARN for object .
In the Add ARN(s) dialog box, provide the details about your resource.
For the Amazon S3 bucket, specify the Amazon S3 bucket to allow access to. For the object, you can choose Any to grant permissions to any object in the bucket. Note You can set Amazon Resource Name (ARN) to a more specific ARN value to allow Amazon RDS to access only specific files or folders in an Amazon S3 bucket. For more information about how to define an access policy for Amazon S3, see Managing access permissions to your Amazon S3 resources .
(Optional) Choose Add additional permissions to add resources to the policy. For example, do the following:
- If your bucket is encrypted with a custom KMS key, select KMS for the service. Select Encrypt , ReEncrypt , Decrypt , DescribeKey , and GenerateDataKey for actions. Enter the ARN of your custom key as the resource. For more information, see Protecting Data Using Server-Side Encryption with KMS keys Stored in AWS Key Management Service (SSE-KMS) in the Amazon Simple Storage Service User Guide .
- If you want Amazon RDS to access to access other buckets, add the ARNs for these buckets. Optionally, you can also grant access to all buckets and objects in Amazon S3.
Choose Next: Tags and then Next: Review .
For Name , enter a name for your IAM policy, for example rds-s3-integration-policy . You use this name when you create an IAM role to associate with your DB instance. You can also add an optional Description value.
Choose Create policy .
Create an AWS Identity and Access Management (IAM) policy that grants Amazon RDS access to an Amazon S3 bucket. After you create the policy, note the ARN of the policy. You need the ARN for a subsequent step.
Include the appropriate actions in the policy based on the type of access required:
- GetObject – Required to transfer files from an Amazon S3 bucket to Amazon RDS.
- ListBucket – Required to transfer files from an Amazon S3 bucket to Amazon RDS.
- PutObject – Required to transfer files from Amazon RDS to an Amazon S3 bucket.
The following AWS CLI command creates an IAM policy named rds-s3-integration-policy with these options. It grants access to a bucket named your-s3-bucket-arn .
Example For Linux, macOS, or Unix:
The following example includes permissions for custom KMS keys.
For Windows:
This step is necessary only in the following conditions:
- You plan to upload files to an Amazon S3 bucket from one account (account A) and access them from a different account (account B).
- Account B owns the bucket.
- Account B needs full control of objects loaded into the bucket.
If the preceding conditions don't apply to you, skip to Step 3: Create an IAM role for your DB instance and attach your policy .
To create your bucket policy, make sure you have the following:
- The account ID for account A
- The user name for account A
- The ARN value for the Amazon S3 bucket in account B
To create or edit a bucket policy
Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/ .
In the Buckets list, choose the name of the bucket that you want to create a bucket policy for or whose bucket policy you want to edit.
Choose Permissions .
Under Bucket policy , choose Edit . This opens the Edit bucket policy page.
On the **Edit bucket policy **page, explore Policy examples in the Amazon S3 User Guide , choose Policy generator to generate a policy automatically, or edit the JSON in the Policy section.
If you choose Policy generator , the AWS Policy Generator opens in a new window:
On the AWS Policy Generator page, in Select Type of Policy , choose S3 Bucket Policy .
Add a statement by entering the information in the provided fields, and then choose Add Statement . Repeat for as many statements as you would like to add. For more information about these fields, see the IAM JSON policy elements reference in the IAM User Guide . Note For convenience, the Edit bucket policy page displays the **Bucket ARN **(Amazon Resource Name) of the current bucket above the Policy text field. You can copy this ARN for use in the statements on the AWS Policy Generator page.
After you finish adding statements, choose Generate Policy .
Copy the generated policy text, choose Close , and return to the Edit bucket policy page in the Amazon S3 console.
In the Policy box, edit the existing policy or paste the bucket policy from the Policy generator. Make sure to resolve security warnings, errors, general warnings, and suggestions before you save your policy.
Choose Save changes , which returns you to the Bucket Permissions page.
This step assumes that you have created the IAM policy in Step 1: Create an IAM policy for your Amazon RDS role . In this step, you create a role for your RDS for Oracle DB instance and then attach your policy to the role.
To create an IAM role to allow Amazon RDS access to an Amazon S3 bucket
In the navigation pane, choose Roles .
Choose Create role .
For AWS service , choose RDS .
For Select your use case , choose RDS – Add Role to Database .
Choose Next .
For Search under Permissions policies , enter the name of the IAM policy you created, and choose the policy when it appears in the list.
Set Role name to a name for your IAM role, for example rds-s3-integration-role . You can also add an optional Description value.
To create a role and attach your policy to it
Create an IAM role that Amazon RDS can assume on your behalf to access your Amazon S3 buckets.
We recommend using the https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourcearn and https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html#condition-keys-sourceaccount global condition context keys in resource-based trust relationships to limit the service's permissions to a specific resource. This is the most effective way to protect against the confused deputy problem .
You might use both global condition context keys and have the aws:SourceArn value contain the account ID. In this case, the aws:SourceAccount value and the account in the aws:SourceArn value must use the same account ID when used in the same statement.
- Use aws:SourceArn if you want cross-service access for a single resource.
- Use aws:SourceAccount if you want to allow any resource in that account to be associated with the cross-service use.
In the trust relationship, make sure to use the aws:SourceArn global condition context key with the full Amazon Resource Name (ARN) of the resources accessing the role.
The following AWS CLI command creates the role named rds-s3-integration-role for this purpose. Example
For Linux, macOS, or Unix:
For more information, see Creating a role to delegate permissions to an IAM user in the IAM User Guide .
After the role is created, note the ARN of the role. You need the ARN for a subsequent step.
Attach the policy you created to the role you created.
The following AWS CLI command attaches the policy to the role named rds-s3-integration-role . Example
Replace your-policy-arn with the policy ARN that you noted in a previous step.
The last step in configuring permissions for Amazon S3 integration is associating your IAM role with your DB instance. Note the following requirements:
- You must have access to an IAM role with the required Amazon S3 permissions policy attached to it.
- You can only associate one IAM role with your RDS for Oracle DB instance at a time.
- The status of your instance must be available .
To associate your IAM role with your RDS for Oracle DB instance
Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/ .
Choose Databases from the navigation pane.
If your database instance is unavailable, choose Actions and then Start . When the instance status shows Started , go to the next step.
Choose the Oracle DB instance name to display its details.
On the Connectivity & security tab, scroll down to the Manage IAM roles section at the bottom of the page.
Choose the role to add in the Add IAM roles to this instance section.
Choose Add role .
The following AWS CLI command adds the role to an Oracle DB instance named mydbinstance .
Replace your-role-arn with the role ARN that you noted in a previous step. S3_INTEGRATION must be specified for the --feature-name option.
To use Amazon RDS for Oracle Integration with Amazon S3, your Amazon RDS for Oracle DB instance must be associated with an option group that includes the S3_INTEGRATION option.
To configure an option group for Amazon S3 integration
Create a new option group or identify an existing option group to which you can add the S3_INTEGRATION option.
For information about creating an option group, see Creating an option group .
Add the S3_INTEGRATION option to the option group.
For information about adding an option to an option group, see Adding an option to an option group .
Create a new Oracle DB instance and associate the option group with it, or modify an Oracle DB instance to associate the option group with it.
For information about creating a DB instance, see Creating an Amazon RDS DB instance .
For information about modifying an Oracle DB instance, see Modifying an Amazon RDS DB instance .
For example, the following AWS CLI command adds the S3_INTEGRATION option to an option group named myoptiongroup . Example
To transfer files between an Oracle DB instance and an Amazon S3 bucket, you can use the Amazon RDS package rdsadmin_s3_tasks . You can compress files with GZIP when uploading them, and decompress them when downloading.
Note The procedures in rdsadmin_s3_tasks upload or download the files in a single directory. You can't include subdirectories in these operations.
Uploading files from your RDS for Oracle DB instance to an Amazon S3 bucket
Downloading files from an amazon s3 bucket to an oracle db instance, monitoring the status of a file transfer.
To upload files from your DB instance to an Amazon S3 bucket, use the procedure rdsadmin.rdsadmin_s3_tasks.upload_to_s3 . For example, you can upload Oracle Recovery Manager (RMAN) backup files or Oracle Data Pump files. The maximum object size in an Amazon S3 bucket is 5 TB. For more information about working with objects, see Amazon Simple Storage Service User Guide . For more information about performing RMAN backups, see Performing common RMAN tasks for Oracle DB instances .
The rdsadmin.rdsadmin_s3_tasks.upload_to_s3 procedure has the following parameters.
The return value for the rdsadmin.rdsadmin_s3_tasks.upload_to_s3 procedure is a task ID.
The following example uploads all of the files in the DATA_PUMP_DIR directory to the Amazon S3 bucket named mys3bucket . The files aren't compressed.
The following example uploads all of the files with the prefix db in the DATA_PUMP_DIR directory to the Amazon S3 bucket named mys3bucket . Amazon RDS applies the highest level of GZIP compression to the files.
The following example uploads all of the files in the DATA_PUMP_DIR directory to the Amazon S3 bucket named mys3bucket . The files are uploaded to a dbfiles folder. In this example, the GZIP compression level is 1 , which is the fastest level of compression.
The following example uploads all of the files in the DATA_PUMP_DIR directory to the Amazon S3 bucket named mys3bucket . The files are uploaded to a dbfiles folder and ora is added to the beginning of each file name. No compression is applied.
The following example assumes that the command is run in account A, but account B requires full control of the bucket contents. The command rdsadmin_s3_tasks.upload_to_s3 transfers all files in the DATA_PUMP_DIR directory to the bucket named s3bucketOwnedByAccountB . Access control is set to FULL_CONTROL so that account B can access the files in the bucket. The GZIP compression level is 6 , which balances speed and file size.
In each example, the SELECT statement returns the ID of the task in a VARCHAR2 data type.
You can view the result by displaying the task's output file.
Replace task-id with the task ID returned by the procedure.
Note Tasks are executed asynchronously.
To download files from an Amazon S3 bucket to an RDS for Oracle instance, use the Amazon RDS procedure rdsadmin.rdsadmin_s3_tasks.download_from_s3 .
When you download files using the procedure download_from_s3 , consider the following:
- The download limit is 2000 files per procedure call. If you need to download more than 2000 files from Amazon S3, split your download into separate actions, with no more than 2000 files per procedure call.
- If a file exists in your download folder, and you attempt to download a file with the same name, download_from_s3 skips the download. To remove a file from the download directory, use UTL_FILE.FREMOVE , found on the Oracle website.
The download_from_s3 procedure has the following parameters.
The return value for the rdsadmin.rdsadmin_s3_tasks.download_from_s3 procedure is a task ID.
The following example downloads all files in the Amazon S3 bucket named mys3bucket to the DATA_PUMP_DIR directory. The files aren't compressed, so no decompression is applied.
The following example downloads all of the files with the prefix db in the Amazon S3 bucket named mys3bucket to the DATA_PUMP_DIR directory. The files are compressed with GZIP, so decompression is applied. The parameter p_error_on_zero_downloads turns on prefix error checking, so if the prefix doesn't match any files in the bucket, the task raises and exception and fails.
The following example downloads all of the files in the folder myfolder/ in the Amazon S3 bucket named mys3bucket to the DATA_PUMP_DIR directory. Use the p_s3_prefix parameter to specify the Amazon S3 folder. The uploaded files are compressed with GZIP, but aren't decompressed during the download.
The following example downloads the file mydumpfile.dmp in the Amazon S3 bucket named mys3bucket to the DATA_PUMP_DIR directory. No decompression is applied.
Note Tasks are executed asynchronously. You can use the UTL_FILE.FREMOVE Oracle procedure to remove files from a directory. For more information, see FREMOVE procedure in the Oracle documentation.
File transfer tasks publish Amazon RDS events when they start and when they complete. For information about viewing events, see Viewing Amazon RDS events .
You can view the status of an ongoing task in a bdump file. The bdump files are located in the /rdsdbdata/log/trace directory. Each bdump file name is in the following format.
Replace task-id with the ID of the task that you want to monitor.
You can use the rdsadmin.rds_file_util.read_text_file stored procedure to view the contents of bdump files. For example, the following query returns the contents of the dbtask-1546988886389-2444.log bdump file.
You can remove Amazon S3 integration option from a DB instance.
To remove the Amazon S3 integration option from a DB instance, do one of the following:
To remove the Amazon S3 integration option from multiple DB instances, remove the S3_INTEGRATION option from the option group to which the DB instances belong. This change affects all DB instances that use the option group. For more information, see Removing an option from an option group .
To remove the Amazon S3 integration option from a single DB instance, modify the instance and specify a different option group that doesn't include the S3_INTEGRATION option. You can specify the default (empty) option group or a different custom option group. For more information, see Modifying an Amazon RDS DB instance .
