Oracle Database Integration

Overview

The Oracle integration provides health and performance metrics for your Oracle database in near real-time. Visualize these metrics with the provided dashboard and create monitors to alert your team on Oracle database states.

Enable Database Monitoring (DBM) for enhanced insights into query performance and database health. In addition to the standard integration features, Datadog DBM provides query-level metrics, live and historical query snapshots, wait event analysis, database load, query explain plans, and blocking query insights.

Setup

Installation

Prerequisite

To use the Oracle integration you can either use the native client (no additional install steps required), or the Oracle Instant Client.

Oracle Instant Client

Skip this step if you are not using Instant Client.

Linux

Follow the Oracle Instant Client installation for Linux.
Verify that the Instant Client Basic package is installed. Find it on Oracle's download page.

After the Instant Client libraries are installed, ensure the runtime linker can find the libraries, for example:
```
# Put the library location in the /etc/datadog-agent/environment file.

echo "LD_LIBRARY_PATH=/u01/app/oracle/product/instantclient_19" \
>> /etc/datadog-agent/environment
```

Windows

Follow the Oracle Windows installation guide to configure your Oracle Instant Client.
Verify the following:
- The Microsoft Visual Studio 2017 Redistributable or the appropriate version is installed for the Oracle Instant Client.
- The Instant Client Basic package from Oracle's download page is installed, and is available to all users on the given machine (for example, C:\oracle\instantclient_19).
- The PATH environment variable contains the directory with the Instant Client (for example, C:\oracle\instantclient_19).

Datadog user creation

Multi-tenant

Create user

Create a read-only login to connect to your server and grant the required permissions:

CREATE USER c##datadog IDENTIFIED BY &password CONTAINER = ALL ;

ALTER USER c##datadog SET CONTAINER_DATA=ALL CONTAINER=CURRENT;

Grant permissions

Log on as sysdba, and grant the following permissions:

grant create session to c##datadog ;
grant select on v_$session to c##datadog ;
grant select on v_$database to c##datadog ;
grant select on v_$containers to c##datadog;
grant select on v_$sqlstats to c##datadog ;

grant select on v_$locked_object to c##datadog;
grant select on dba_objects to c##datadog;
grant select on cdb_data_files to c##datadog;
grant select on dba_data_files to c##datadog;

connect / as sysdba
alter session set container = your_pdb ;
grant set container to c##datadog ;

Configuration

To configure this check for an Agent running on a host:

Edit the oracle.d/conf.yaml file, in the conf.d/ folder at the root of your Agent's configuration directory. Update the server and port to set the masters to monitor. See the sample oracle.d/conf.yaml for all available configuration options.

init_config:

instances:
   ## @param server - string - required
   ## The IP address or hostname of the Oracle Database Server.
   #
   - server: localhost:1521

     ## @param service_name - string - required
     ## The Oracle Database service name. To view the services available on your server,
     ## run the following query: `SELECT value FROM v$parameter WHERE name='service_names'`
     #
     service_name: <SERVICE_NAME>

     ## @param username - string - required
     ## The username for the Datadog user account.
     #
     username: <USERNAME>

     ## @param password - string - required
     ## The password for the Datadog user account.
     #
     password: <PASSWORD>

Note: For the Agent releases between 7.50.1 (inclusive) and 7.53.0 (exclusive), the configuration subdirectory is oracle-dbm.d. For all other Agent releases, the configuration directory is oracle.d.

Note: Oracle Real Application Cluster (RAC) customers must configure the Agent for each RAC node, because the Agent collects information from every node separately by querying V$ views. The Agent doesn't query any GV$ views to avoid generating interconnect traffic.

Restart the Agent.

Connect to Oracle through TCPS

To connect to Oracle through TCPS (TCP with SSL), uncomment the protocol configuration option and select TCPS. Update the server option to set the TCPS server to monitor.

```yaml
init_config:

instances:
  ## @param server - string - required
  ## The IP address or hostname of the Oracle Database Server.
  #
  - server: localhost:1522

    ## @param service_name - string - required
    ## The Oracle Database service name. To view the services available on your server,
    ## run the following query:
    #
    service_name: "<SERVICE_NAME>"

    ## @param username - string - required
    ## The username for the user account.
    #
    username: <USER>

    ## @param password - string - required
    ## The password for the user account.
    #
    password: "<PASSWORD>"

    ## @param protocol - string - optional - default: TCP
    ## The protocol to connect to the Oracle Database Server. Valid protocols include TCP and TCPS.
    ##
    #
    protocol: TCPS
```

Validation

Run the Agent's status subcommand and look for oracle under the Checks section.

Custom query

Providing custom queries is also supported. Each query must have two parameters:

Parameter	Description
`query`	This is the SQL to execute. It can be a simple statement or a multi-line script. All rows of the result are evaluated.
`columns`	This is a list representing each column, ordered sequentially from left to right. There are two required pieces of data: a. `type` - This is the submission method (`gauge`, `count`, etc.). b. name - This is the suffix used to form the full metric name. If `type` is `tag`, this column is instead considered as a tag which is applied to every metric collected by this particular query.

Optionally use the tags parameter to apply a list of tags to each metric collected.

The following:

self.gauge('oracle.custom_query.metric1', value, tags=['tester:oracle', 'tag1:value'])
self.count('oracle.custom_query.metric2', value, tags=['tester:oracle', 'tag1:value'])

is what the following example configuration would become:

- query: | # Use the pipe if you require a multi-line script.
    SELECT columns
    FROM tester.test_table
    WHERE conditions
  columns:
    # Put this for any column you wish to skip:
    - {}
    - name: metric1
      type: gauge
    - name: tag1
      type: tag
    - name: metric2
      type: count
  tags:
    - tester:oracle

See the sample oracle.d/conf.yaml for all available configuration options.
