Introduction

The Applications panel enables you to manage the Applications in CAST Imaging:

Add Application (import new / refresh existing)

To add a new Application, or add an Application that already exists (known as a refresh), you must already have actioned an export of the application into a ZIP file created using the exporter.exe tool - see Export the CSV data. When the ZIP is ready, you can add it using panel 2:

Import new Application data

Upload the ZIP file containing the Application data (see Export the CSV data for information about generating this ZIP). You can either:

• drag and drop the ZIP file into the square in the middle of the screen
• or you can use the Import button to browse for the ZIP you require

If the ZIP file is accepted (a check will be done to ensure the ZIP contains the correct data files), the Applications contained in the ZIP (a ZIP can contain more than one Application) will be imported:

On completion, a summary is shown, with an option to view the import logs:

If you would like to view the imported Application, click CAST Imaging in the top left corner of the screen then select the Application in the following screen:

Import multiple application data simultaneously

By default, CAST Imaging is configured to handle the upload of one application at a time, any additional applications that are uploaded while an upload action is ongoing are queued. This behaviour can be modified to allow CAST Imaging to accept multiple application uploads simultaneously. This configuration is handled by the WORKER_POOL_SIZE parameter located in the following files depending on your environment:

Microsoft Windows traditional installer ≥ 2.17
%APPDATA%\CAST\ImagingSystem\imagingservice\imagingetl.json

Microsoft Windows traditional installer ≤ 2.16
%APPDATA%\CAST\ImagingSystem\imagingservice\imagingetl.bat
 
Docker Installer extension (located in the deployed extension location): 
etl/app.config

By default, WORKER_POOL_SIZE parameter is set to 1 (one upload at a time) but it is not present in the config files. If you need to update the WORKER_POOL_SIZE value, then you must add the parameter manually to the file. For example, to set the value to 3 (allowing the upload of 3 applications simultaneously), add a new line at the end of the file containing the following:

...
	"HTTP_ENDPOINT": "http://server:8084",
	"WORKER_POOL_SIZE": 3
}

...
	-AUDIT_TRAIL=true ^
	-WORKER_POOL_SIZE=3
if errorlevel 1 exit /b 1
exit /b 0

	"HTTP_ENDPOINT": "http://127.0.0.1:8084",
	"WORKER_POOL_SIZE": 3
}

Save the file and restart the CAST Imaging "etl" Windows Service or Docker container to ensure that the changes are taken into account.

Example

In the below example, the value is set to "3" which lets you import "3" applications simultaneously. 

The process of importing the apps runs simultaneously (without waiting in queue). This is represented with a loading animation icon in 'Import Logs' column.:

If the WORKER_POOL_SIZE parameter is set to 3 and if you import 5 applications then the first three selected applications are simultaneously imported and the other two will be in queue (waiting). When the import (job) of an application in simultaneous mode is completed, then the fourth application (which is in queue) automatically moves to simultaneous mode:

If multiple applications are imported following message is displayed 'Importing Applications'. 

Refresh existing Application data

You can refresh data for Applications that have already been imported - a refresh will cause data in the new ZIP to be merged with existing data already imported into CAST Imaging - so new objects may be visible and existing objects may be removed or updated. Upload the ZIP in exactly the same way as for importing new Application data.

Remove Application data

Removing an Application will cause all associated data to be purged from CAST Imaging. This action cannot be reversed. Select the Applications you wish to remove by placing a tick in the check box, then click Remove to start the removal process:

You will be prompted to confirm that you do want to remove the Application (with the application name/s) - this action cannot be reversed:

The removal process will then proceed, following message is displayed "Removing applications" with an option to view the removal logs:

On completion, following confirmation message "Applications removed successfully" is displayed.
