# Admin Client

`AdminClient` provides database management operations. It uses the same database connection mode as `Client`, but only supports database management-related operations.

## Connect to an embedded seekdb instance

Connect to a local embedded seekdb instance by using `AdminClient`.

```python
import pyseekdb

# Embedded mode - Database management
admin = pyseekdb.AdminClient(path="./seekdb")
```

Parameter description:

| Parameter | Value Type | Required | Description | Example Value |
| --- | --- | --- | --- | --- |
| `path` | string | Optional | The path of the seekdb data directory. seekdb stores database files in this directory and loads them when it starts. | `./seekdb` |

## Connect to a remote server

Connect to a remote server by using `AdminClient`. This way, you can connect to a seekdb instance or an OceanBase Database instance.

:::tip

Before you connect to a remote server, make sure that you have deployed a server mode seekdb instance or an OceanBase Database instance.<br/>For information about how to deploy a server mode seekdb instance, see [Overview](../../../400.guides/400.deploy/50.deploy-overview.md).<br/>For information about how to deploy an OceanBase Database instance, see [Overview](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000003976427).

Example: Connect to a server mode seekdb instance

```python
import pyseekdb

# Remote server mode - Database management
admin = pyseekdb.AdminClient(
    host="127.0.0.1",
    port=2881,
    user="root",
    password=""  # Can be retrieved from SEEKDB_PASSWORD environment variable
)
```

Parameter description:

| Parameter | Value Type | Required | Description | Example Value |
| --- | --- | --- | --- | --- |
| `host` | string | Yes | The IP address of the server where the instance resides. | `127.0.0.1` |
| `prot` | string | Yes | The port of the instance. The default value is 2881. | `2881` |
| `user` | string | Yes | The username. The default value is root. | `root` |
| `password` | string | Yes | The password corresponding to the username. If you do not specify `password` or specify an empty string, the system retrieves the password from the `SEEKDB_PASSWORD` environment variable. | |

Example: Connect to an OceanBase Database instance

```python
import pyseekdb

# Remote server mode - Database management
admin = pyseekdb.AdminClient(
    host="127.0.0.1",
    port=2881,
    tenant="test"
    user="root",
    password=""  # Can be retrieved from SEEKDB_PASSWORD environment variable
)
```

Parameter description:

| Parameter | Value Type | Required | Description | Example Value |
| --- | --- | --- | --- | --- |
| `host` | string | Yes | The IP address of the server where the database resides. | `127.0.0.1` |
| `prot` | string | Yes | The port of the OceanBase Database instance. The default value is 2881. | `2881` |
| `tenant` | string | No | The name of the tenant. This parameter is not required for a server mode seekdb instance, but is required for an OceanBase Database instance. The default value is sys. | `test` |
| `user` | string | Yes | The username corresponding to the tenant. The default value is root. | `root` |
| `password` | string | Yes | The password corresponding to the username. If you do not specify `password` or specify an empty string, the system retrieves the password from the `SEEKDB_PASSWORD` environment variable. | |
