        -----
        
        ## 1. Installation
        
        Install this library in a [virtualenv][1] using pip. [virtualenv][1] is a tool to
        create isolated Python environments. The basic problem it addresses is one of
        dependencies and versions, and indirectly permissions.
        
        With [virtualenv][1], it's possible to install this library without needing system
        install permissions, and without clashing with the installed system
        dependencies. Make sure you use Python 3.6+.
        
        
        ### 1.1. Mac/Linux
        
        ```bash
        pip3 install virtualenv
        virtualenv --python python3.6 <your-env>
        source <your-env>/bin/activate
        <your-env>/bin/pip install google-datacatalog-oracle-connector
        ```
        
        ### 1.2. Windows
        
        ```bash
        pip3 install virtualenv
        virtualenv --python python3.6 <your-env>
        <your-env>\Scripts\activate
        <your-env>\Scripts\pip.exe install google-datacatalog-oracle-connector
        ```
        
        ### 1.3. Install from source
        
        #### 1.3.1. Get the code
        
        ````bash
        git clone https://github.com/GoogleCloudPlatform/datacatalog-connectors-rdbms/
        cd datacatalog-connectors-rdbms/google-datacatalog-oracle-connector
        ````
        
        #### 1.3.2. Create and activate a *virtualenv*
        
        ```bash
        pip3 install virtualenv
        virtualenv --python python3.6 <your-env>
        source <your-env>/bin/activate
        ```
        
        #### 1.3.3. Install the library
        
        ```bash
        pip install .
        ```
        
        ## 2. Environment setup
        
        ### 2.1. Auth credentials
        
        #### 2.1.1. Create a service account and grant it below roles
        
        - Data Catalog Admin
        
        #### 2.1.2. Download a JSON key and save it as
        - `<YOUR-CREDENTIALS_FILES_FOLDER>/oracle2dc-datacatalog-credentials.json`
        
        > Please notice this folder and file will be required in next steps.
        
        ### 2.2 Set up Oracle Driver  (Optional)
        This is step is needed when you are running the connector on a machine that does not have the Oracle installation.
        
        #### 2.2.1 Set Oracle client for Linux (Cloud Shell)
        Download the zip file:
        https://oracle.github.io/odpi/doc/installation.html#linux
        
        ```bash
        # Unzip it
        unzip instantclient-basic-linux.x64-19.5.0.0.0dbru.zip
        # Set Oracle library ENV Var on the unzip dir
        export LD_LIBRARY_PATH=/oracle2datacatalog/bin/instantclient_19_5
        ```
        
        #### 2.2.2  Set Oracle client for Mac
        Download the zip file:
        https://oracle.github.io/odpi/doc/installation.html#macos
        
        ```bash
        # Unzip it
        unzip instantclient-basic-macos.x64-19.3.0.0.0dbru.zip
        # Set Oracle library ENV Var on the unzip dir
        export LD_LIBRARY_PATH=/oracle2datacatalog/bin/instantclient_19_3
        ```
        
        ### 2.3. Set environment variables
        
        Replace below values according to your environment:
        
        ```bash
        export GOOGLE_APPLICATION_CREDENTIALS=data_catalog_credentials_file
        
        export ORACLE2DC_DATACATALOG_PROJECT_ID=google_cloud_project_id
        export ORACLE2DC_DATACATALOG_LOCATION_ID=google_cloud_location_id
        export ORACLE2DC_ORACLE_SERVER=oracle_server
        export ORACLE2DC_ORACLE_SERVER_PORT=oracle_server_port
        export ORACLE2DC_ORACLE_USERNAME=oracle_username
        export ORACLE2DC_ORACLE_PASSWORD=oracle_password
        export ORACLE2DC_ORACLE_DATABASE_SERVICE=oracle_db_service
        export ORACLE2DC_RAW_METADATA_CSV=oracle_raw_csv (If supplied ignores the Oracle server credentials)

        ## 7. Troubleshooting
        
        In the case a connector execution hits Data Catalog quota limit, an error will be raised and logged with the following detailement, depending on the performed operation READ/WRITE/SEARCH: 
        ```
        status = StatusCode.RESOURCE_EXHAUSTED
        details = "Quota exceeded for quota metric 'Read requests' and limit 'Read requests per minute' of service 'datacatalog.googleapis.com' for consumer 'project_number:1111111111111'."
        debug_error_string = 
        "{"created":"@1587396969.506556000", "description":"Error received from peer ipv4:172.217.29.42:443","file":"src/core/lib/surface/call.cc","file_line":1056,"grpc_message":"Quota exceeded for quota metric 'Read requests' and limit 'Read requests per minute' of service 'datacatalog.googleapis.com' for consumer 'project_number:1111111111111'.","grpc_status":8}"
        ```
