Manage multiple servers



You can perform batch operations on multiple ColdFusion Server instances from Server Manager.

When you drag and drop any setting, if that setting exists on the server where the settings are being dropped, the settings get overridden with the new settings. For example, if data source named XXX is being dropped on a server and if that data source already exists on the other server, then the data source gets overridden with the new setting, without any warning.

In a batch operation, you can perform the following tasks:

    Apply configuration settings on multiple servers

    The left-pane of Server Manager lists the settings that you can configure for one or more ColdFusion servers. To apply configuration settings on multiple ColdFusion servers:

    1. Configure the settings for one ColdFusion server using the settings available in the left-pane of the Server Manager.

    2. Select the other ColdFusion servers to which the settings have to be applied.

    3. Right-click a setting and select the Apply to Selected Servers option. Alternatively, you can drag-and-drop the setting to the selected servers in the right-pane of the Server Manager.

      At the bottom of the Server Manager window, a progress bar displays the status of the setting being applied. Once the task is completed, a message is displayed to confirm if the task was successful.

    4. On the right-side of the progress bar, there are two icons, Remove and Save Snapshot. To save a batch operation log, click the Save Snapshot icon and save the log file.

    Apart from applying settings to multiple ColdFusion servers, you can use the Server Manager to perform the following actions:

    Settings

    Actions

    Datasources

    • Add a datasource by right-clicking the Datasources setting in the left pane.

    • Edit an existing datasource by right-clicking the datasource in the left pane.

    • Remove an existing datasource by right-clicking the datasource in the left pane.

    • Verify an existing datasource by right-clicking the datasource in the left pane. If the verification is successful, a green icon appears beside the data source node. Otherwise, an error message is displayed along with a red icon beside the data source.

    • Verify all data sources by right-clicking the Data Sources node in the left pane.

    Mappings

    • Add a mapping by right-clicking the Mappings setting.

    • Edit an existing mapping by right-clicking the mapping in the left pane.

    • Remove an existing datasource by right-clicking the mapping in the left pane.

    Request Tuning

    Edit and refresh the request tuning configuration by right-clicking the setting in the left pane.

    Logging

    Edit and refresh the log settings by right-clicking the setting in the left pane.
    Note: To edit any settings, first refresh them to fetch the latest setting and then edit them. The options for editing the configuration settings are the same as in ColdFusion Administrator.

    Clear template cache

    Using Server Manager you can clear the template cache for multiple servers simultaneously. To clear the template cache:

    1. Select the servers by selecting the Apply server task and settings check box.

    2. Click the Server Tasks option from the upper-right corner.

    3. Click Clear Template Cache.

      A progress bar at the bottom displays the cache clearing status.

      After the task is completed, you can save the cache log by clicking the Save Snapshot icon or remove it by clicking Remove.

    Apply hot fix

    You can update multiple ColdFusion Server instances, once they are registered with Server Manager.

    Note: After applying a hotfix, restart the server for the hotfix to take effect.

    To apply a hot fix to multiple servers:

    1. Select the servers instances that need to be updated by selecting the Apply server task and settings check box.

    2. From the upper-right menu bar, click Server Tasks > Apply Hot Fix.

    3. Click Yes to confirm.

    4. Navigate to the location of the JAR file to be used as a hot fix.

    5. Click Open to apply the hot fix to the server instances.

    Once you apply a hot fix (.jar) to a server instance, that JAR file appears in the <ColdFusion_home>/lib/updates directory.

    Note: This is useful only if the hotfix is a JAR file. Place this JAR file under <CF_Home/lib/updates> directory. If you place a hotfix file to any other location, then you have to implement it manually.

    Set Server Manager preferences

    To set the Server Manager preferences, click Settings > Preferences. You can set the following preferences in Server Manager:

    • Polling Interval: Use this option to set the interval (in seconds) for Server Manager to check for any alerts and warnings on ColdFusion server. In addition, if the status of your server instance on Server Manager is “Unreachable”, then Server Manager tries to reconnect to the server after the specified polling interval.

    • Stop batch operations on error: This check box is selected by default. If you deselect this check box, Server Manager continues to perform the batch operations even if an error occurs. Batch operations include tasks such as applying hot fix, clearing template cache, fetching settings from server, or applying settings from one server to multiple servers.

    • Alert window position: Use this drop-down list to select the position where the notifications and alerts would be displayed in Server Manager.

    • Close the dialog box after receiving a server acknowledgment: Select this option to close any edited server configuration dialog box only after receiving the acknowledgment.

    • Show batch progress: This option is selected by default. If you do not want to see the progress of the batch operations at the bottom of the Server Manager window, then deselect this option.

    • Use inbuilt browser: By selecting this check box, you can open any server URL in the internal browser or the default browser in system.
