title: Run the DB2 Connector Externally
slug: /connectors/database/db2/yaml

{% connectorDetailsHeader

In this section, we provide guides and references to use the DB2 connector.
Configure and schedule DB2 metadata and profiler workflows from the OpenMetadata UI:
- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)
- [Data Profiler](#data-profiler)
- [Data Quality](#data-quality)
- [dbt Integration](#dbt-integration)

## Requirements
To create a new Db2 user please follow the guidelines mentioned [here](https://www.ibm.com/docs/ko/samfess/8.2.0?topic=schema-creating-users-manually)
Db2 user must have the below permissions to ingest the metadata:
- `SELECT` privilege on `SYSCAT.SCHEMATA` to fetch the metadata of schemas.
```sql
-- Grant SELECT on tables for schema metadata
GRANT SELECT ON SYSCAT.SCHEMATA TO USER_NAME;
```
- `SELECT` privilege on `SYSCAT.TABLES` to fetch the metadata of tables.
```sql
-- Grant SELECT on tables for table metadata
GRANT SELECT ON SYSCAT.TABLES TO USER_NAME;
```
- `SELECT` privilege on `SYSCAT.VIEWS` to fetch the metadata of views.
```sql
-- Grant SELECT on tables for view metadata
GRANT SELECT ON SYSCAT.VIEWS TO USER_NAME;
```
### Profiler & Data Quality
Executing the profiler workflow or data quality tests, will require the user to have `SELECT` permission on the tables/schemas where the profiler/tests will be executed. More information on the profiler workflow setup can be found [here](/how-to-guides/data-quality-observability/profiler/workflow) and data quality tests [here](/how-to-guides/data-quality-observability/quality).

### Python Requirements
{% partial file="/v1.5/connectors/python-requirements.md" /%}
To run the DB2 ingestion, you will need to install:
```bash
pip3 install "openmetadata-ingestion[db2]"
```
## Metadata Ingestion
All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/db2Connection.json)
you can find the structure to create a connection to DB2.
In order to create and run a Metadata Ingestion workflow, we will follow
the steps to create a YAML configuration able to connect to the source,
process the Entities if needed, and reach the OpenMetadata server.
The workflow is modeled around the following
[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)
### 1. Define the YAML Config
This is a sample config for DB2:
{% codePreview %}
{% codeInfoContainer %}
#### Source Configuration - Service Connection
{% codeInfo srNumber=1 %}
**username**: Specify the User to connect to DB2. It should have enough privileges to read all the metadata.
{% /codeInfo %}
{% codeInfo srNumber=2 %}
**password**: Password to connect to DB2.
{% /codeInfo %}
{% codeInfo srNumber=3 %}
**hostPort**: Enter the fully qualified hostname and port number for your DB2 deployment in the Host and Port field.
{% /codeInfo %}
{% codeInfo srNumber=4 %}
**database**: Database of the data source.
{% /codeInfo %}
{% partial file="/v1.5/connectors/yaml/database/source-config-def.md" /%}
{% partial file="/v1.5/connectors/yaml/ingestion-sink-def.md" /%}
{% partial file="/v1.5/connectors/yaml/workflow-config-def.md" /%}
#### Advanced Configuration
{% codeInfo srNumber=5 %}
**Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to database during the connection. These details must be added as Key-Value pairs.
2024-06-18 15:53:06 +02:00
{% /codeInfo %}
{% codeInfo srNumber=6 %}
**Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to database during the connection. These details must be added as Key-Value pairs.
2024-06-18 15:53:06 +02:00
- In case you are using Single-Sign-On (SSO) for authentication, add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "sso_login_url"`
{% /codeInfo %}
{% /codeInfoContainer %}
{% codeBlock fileName="filename.yaml" %}
```yaml {% isCodeBlock=true %}
source:
type: db2
serviceName: local_db2
serviceConnection:
config:
type: Db2
```
```yaml {% srNumber=1 %}
username: openmetadata_user
```
```yaml {% srNumber=2 %}
password: openmetadata_password
```
```yaml {% srNumber=3 %}
hostPort: localhost:5432
```
```yaml {% srNumber=4 %}
# databaseSchema: schema
```
```yaml {% srNumber=5 %}
# connectionOptions:
# key: value
```
```yaml {% srNumber=6 %}
# connectionArguments:
# key: value
```
