The Dropbox connector supports uploading to and downloading from the Dropbox cloud storage service.

Overview

Each Dropbox connector connects to a specified Dropbox storage account. Within the remote storage, you set a single folder as the upload target, and a list of folders as the download target.

Files that reach the Dropbox connector in the CData Arc flow are uploaded to the upload target folder, and files found in the download target folder are downloaded and entered into the Arc flow. The connector supports upload and download filters to send and receive only specific file names and/or file extensions.

Account authentication uses OAuth, so you must enter account credentials in an external site portal the first time the connector connects. The external portal generates an OAuth token that the connector uses to connect, then the connector handles token refresh automatically.

Connector Configuration

This section contains all of the configurable connector properties.

Settings Tab

Authorization

• Connector Id The static, unique identifier for the connector.
• Connector Type Displays the connector name and a description of what it does.
• Connector Description An optional field to provide a free-form description of the connector and its role in the flow.

Use the Connect button to authenticate the connector with the storage service the first time. You are redirected to a site login portal. After you provide the account credentials, an authentication token is returned to Arc and stored for repeat use.

Send

Settings related to uploading to the remote storage.

• Remote Folder Files processed by the connector are uploaded to this folder.
• Overwrite Whether to overwrite or skip existing files.

Receive

Settings related to downloading from the remote storage.

• Remote Folder The remote folder from which files are downloaded. Use a comma-delimited list to specify multiple paths.
• File Mask A glob pattern that determines which files within the Remote Path should be downloaded (for example, *.txt).
• Delete Check this to delete successfully downloaded files from the remote storage.

Caching

Settings related to caching and comparing files between multiple downloads.

• File Size Comparison Check this to keep a record of downloaded file names and sizes. Previously downloaded files are skipped unless the file size is different than the last download.
• Timestamp Comparison Check this to keep a record of downloaded file names and last-modified timestamps. Previously downloaded files are skipped unless the timestamp is different than the last download.

Note: When you enable caching, the file names are case-insensitive. For example, the connector cannot distinguish between TEST.TXT and test.txt.

Automation Tab

Automation Settings

Settings related to the automatic processing of files by the connector.

• Send Whether files arriving at the connector are automatically uploaded.
• Retry Interval The amount of time before a failed upload is retried.
• Max Attempts The maximum number of times the connector processes the input file. Success is measured based on a successful server acknowledgement. If you set this to 0, the connector retries the file indefinitely.
• Receive Whether the connector should automatically poll the remote download path for files to download.
• Receive Interval The interval between automatic download attempts.
• Minutes Past the Hour The minutes offset for an hourly schedule. Only applicable when the interval setting above is set to Hourly. For example, if this value is set to 5, the automation service downloads at 1:05, 2:05, 3:05, etc.
• Time The time of day that the attempt should occur. Only applicable when the interval setting above is set to Daily, Weekly, or Monthly.
• Day The day on which the attempt should occur. Only applicable when the interval setting above is set to Weekly or Monthly.
• Minutes The number of minutes to wait before attempting the download. Only applicable when the interval setting above is set to Minute.
• Cron Expression A five-position string representing a cron expression that determines when the attempt should occur. Only applicable when the interval setting above is set to Advanced.

Performance

Settings related to the allocation of resources to the connector.

• Max Workers The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Settings > Automation page.
• Max Files The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Settings > Automation page.

アラートタブ

アラートとサービスレベル（SLA）の設定に関連する設定.

コネクタのE メール設定

サービスレベル（SLA）を実行する前に、通知用のE メールアラートを設定する必要があります。アラートを設定をクリックすると、新しいブラウザウィンドウで設定ページが開き、システム全体のアラートを設定することができます。詳しくは、アラートを参照してください。

サービスレベル（SLA）の設定

サービスレベルでは、フロー内のコネクタが送受信すると予想される処理量を設定し、その量が満たされると予想される時間枠を設定できます。CData Arc は、サービスレベルが満たされていない場合にユーザーに警告するE メールを送信し、SLA を At Risk（危険） としてマークします。これは、サービスレベルがすぐに満たされない場合に Violated（違反） としてマークされることを意味します。これにより、ユーザーはサービスレベルが満たされていない理由を特定し、適切な措置を講じることができます。At Risk の期間内にサービスレベルが満たされなかった場合、SLA はViolated としてマークされ、ユーザーに再度通知されます。

サービスレベルを定義するには、予想処理量の条件を追加をクリックします。

• コネクタに個別の送信アクションと受信アクションがある場合は、ラジオボタンを使用してSLA に関連する方向を指定します。
• 検知基準（最小）を、処理が予想されるトランザクションの最小値（量）に設定し、毎フィールドを使用して期間を指定します。
• デフォルトでは、SLA は毎日有効です。これを変更するには、毎日のチェックをOFF にし、希望する曜日のチェックをON にします。
• 期間終了前にステータスを’At Risk’ に設定するタイミングを使用して、SLA がAt Risk としてマークされるようにします。
• デフォルトでは、通知はSLA が違反のステータスになるまで送信されません。これを変更するには、‘At Risk’ 通知を送信のチェックをON にします。

次の例は、月曜日から金曜日まで毎日1000ファイルを受信すると予想されるコネクタに対して構成されたSLA を示しています。1000ファイルが受信されていない場合、期間終了の1時間前にAt Risk 通知が送信されます。

Advanced Tab

Proxy Settings

These are a collection of settings that identify and authenticate to the proxy through which the Dropbox connection should be routed. By default, this section uses the global settings on the Settings Page. Clear the checkbox to supply settings specific to your connector.

• Proxy Type The protocol used by a proxy-based firewall.
• Proxy Host The name or IP address of a proxy-based firewall.
• Proxy Port The TCP port for a proxy-based firewall.
• Proxy User The user name to use to authenticate with a proxy-based firewall.
• Proxy Password A password used to authenticate to a proxy-based firewall.
• Authentication Scheme Leave the default None or choose from one of the following authentication schemes: Basic, Digest, Proprietary, or NTLM.

Advanced Settings

Settings not included in the previous categories.

• Recurse Whether to download files in subfolders of the target remote path.
• Processing Delay The amount of time (in seconds) by which the processing of files placed in the Input folder is delayed. This is a legacy setting. Best practice is to use a File connector to manage local file systems instead of this setting.
• Timeout The length of time (in seconds) the server waits for a connection response before throwing a timeout error.
• Receive Filter A glob pattern filter to determine which files should be downloaded from the remote storage (for example, *.txt). You can use negative patterns to indicate files that should not be downloaded (for example, -*.tmp). Use this setting when you need multiple File Mask patterns. Multiple patterns can be separated by commas, with later filters taking priority except when an exact match is found.

Message

• Save to Sent Folder Check this to copy files processed by the connector to the Sent folder for the connector.
• Sent Folder Scheme Instructs the connector to group messages in the Sent folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all messages for the week in that folder. The blank setting tells the connector to save all messages directly in the Sent folder. For connectors that process many messages, using subfolders helps keep messsages organized and improves performance.

Logging

• Log Level The verbosity of logs generated by the connector. When you request support, set this to Debug.
• Log Subfolder Scheme Instructs the connector to group files in the Logs folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all logs for the week in that folder. The blank setting tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance.
• Log Messages Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Input or Output tabs.

Miscellaneous

Miscellaneous settings are for specific use cases.

• Other Settings Enables you to configure hidden connector settings in a semicolon-separated list (for example, setting1=value1;setting2=value2). Normal connector use cases and functionality should not require the use of these settings.

Establishing a Connection

To establish a connection with the Dropbox connector, use the Connect button on the Settings tab to be directed to a login portal site. Enter your account credentials in this portal; it returns an authentication token to the connector. This process is only required the first time the connector connects to the storage service.

Uploading and Downloading

Upload

To upload files, set the Remote Folder in the Send portion of the Settings page to the folder where files should be uploaded. Each Dropbox connector uploads to a single folder location.

Use the Overwrite remote files option to indicate whether files that already exist in the container should be overwritten or skipped.

After configuration is complete, files placed in the connector Input tab are uploaded to the remote storage. If Send Automation is enabled, the upload happens automatically; otherwise, you can send individual files from the Input tab.

Download

To download files, set the Remote Folder in the Receive portion of the Settings page to the folder from where files should be downloaded. Use a comma-delimited list to specify multiple folders.

Use the File Mask to set a glob filter (for example *.txt) that limits the downloads to files matching the filter. To specify multiple filters, use the Receive Filter option on the Advanced tab.

Use Delete to specify whether successfully downloaded files should be removed from the remote storage.
