## prerequisite

To use the Oracle module do the following:

1.  Install `cx_Oracle` package ([link](https://cx-oracle.readthedocs.io/en/latest/installation.html#install-cx-oracle)).

2.  Install Oracle Client libraries ([link](https://cx-oracle.readthedocs.io/en/latest/installation.html#install-oracle-client)).

3.  Create a read-only `netdata` user with proper access to your Oracle Database Server.

Connect to your Oracle database with an administrative user and execute:

```
ALTER SESSION SET "_ORACLE_SCRIPT"=true;

CREATE USER netdata IDENTIFIED BY <PASSWORD>;

GRANT CONNECT TO netdata;
GRANT SELECT_CATALOG_ROLE TO netdata;
```

### configuration

```yaml
local:
  user: 'netdata'
  password: 'secret'
  server: 'localhost:1521'
  service: 'XE'

remote:
  user: 'netdata'
  password: 'secret'
  server: '10.0.0.1:1521'
  service: 'XE'
```

All parameters are required. Without them module will fail to start.
