To create a dashboard based on an SQL query in InterSystems Analytics, you can follow these general steps:

1. Create a Namespace if Needed:
   Set up a separate namespace where you can compile messages or report outputs. This includes configuring databases for globals and routines for the namespace [1].

2. Import and Prepare Code:
   Develop classes in Studio to fetch and calculate metrics, and compile them for use in your dashboard. Store the processed metrics in persistent classes that can later be used in an analytics cube [1].

3. Global and Package Mapping:
   Configure global and package mappings for the namespaces involved in your analytics. These settings allow data to be retrieved from specified sources when building the dashboard [1].

4. Build Analytics Cube:
   Use the Analytics Architect to create a cube based on the class that stores the metrics. Define dimensions, measures, and time roll-up elements as needed. Compile the cube and verify its structure [1].

5. Create Pivot Tables:
   Access the Analyzer to generate pivot tables based on the cube. Drag dimensions and measures onto rows and columns as appropriate. Save these tables after organizing the data display according to your requirement [1][2].

6. Design and Add Pivot Tables to Dashboard:

   • Open Analytics > User Portal and create a new dashboard.
   • Add widgets (e.g., tables) to the dashboard by selecting the pivot tables created earlier.
   • Arrange and resize widgets for better visibility and presentation [3][2].

7. Add Filters and Controls:
   Configure filter controls directly on widgets in the dashboard editor. Filters allow users to interact and narrow down the data (e.g., by ZIP code or other dimensions). Default values for these controls can also be added to streamline dashboard use [2].

8. Save and Test Dashboard:
   Store the dashboard configuration, test interactions, and verify the appearance and functionality. By default, analytics dashboards auto-save upon modification [2].

By completing the steps above, you can effectively transform your SQL query into an operational analytics dashboard, enabling efficient visualization and filtering for users. [1][3][2]

No, a pre-existing <Signature> element is not required in the XML document before signing it using %XML.Security.Signature. The signing process builds and inserts the <Signature> element during the SignDocument() call, provided the signature object is properly initialized and associated with the document.

The error "Canonicalize error: Signature not found" occurs when the signature's structure does not match the expected format or is not correlated correctly with the document. The %XML.Security.Signature requires the setup of references and methods, and all associated objects must be correct and linked before executing the SignDocument() method.

To resolve the situation:
1. Ensure the SignedInfo section is properly configured using the required signature and digest methods.
2. Associate the Reference instance with the signature object using AddReference().
3. Confirm the document object is correctly serialized before calling the SignDocument() method. This ensures adequate linkage between the XML structure and the signature object [1][2].

You can increase the timeout for CSP Gateway calls, specifically for individual pages or requests, without changing the default configuration of the CSP Gateway.

In the CSP code, use the Timeout property to specify the timeout for the page. This property changes the server response timeout for a specific CSP page only, allowing you to execute long-running operations like expensive SQL queries without impacting the default CSP Gateway timeout settings. For example:

Property Timeout As %Integer;

You can set this property in the OnPreHTTP() method of the page as follows:

ClassMethod OnPreHTTP() As %Boolean
{
    S %response.Timeout = 120 // Set timeout to 2 minutes
    Q 1
}

This ensures the CSP Gateway waits for a longer duration before reporting a timeout for the response. Ensure to reset this setting if not required for subsequent requests, as the default timeout incentivizes efficient server-side code [1].

To optimize the performance of a production system using Pool Size > 1, consider the following suggestions:

1. Parallel Processing using Pool Size:
   Setting a pool size greater than 1 enables multiple concurrent jobs to process messages. This approach is useful if the ordering of messages does not matter. When pool size is increased, each additional pool job adds an OS-level process, which incurs memory and CPU usage based on the work being done. Start with small pool size increments (e.g., 2 or 4) and monitor the impact on queues and system performance before increasing further [1][2].

2. Message Ordering Concerns:
   If message order is important, asynchronous calls with larger pool sizes can lead to inconsistencies. To address this:

   • Use an intermediate process configured with Pool Size = 1 to ensure first-in-first-out (FIFO) processing [3].
   • Alternatively, apply a mechanism such as message routing rules by metadata (e.g., splitting queues by certain keys like patient IDs) to maintain order for related messages across threads [3].

3. Concurrent Updates (e.g., ProcessedCount):
   Concurrent processing can cause record updates to fail or become inconsistent. If synchronization issues arise:

   • Avoid direct SQL updates using %NOLOCK when multiple threads are involved. Locks are necessary to ensure the atomicity of operations but may reduce concurrency.
   • Implement robust mechanisms for updating shared counters, such as lock-based synchronization or queuing updates within dedicated threads to avoid SQL collisions [1][3].

4. Dynamic Pool Size Adjustments:
   Dynamically scaling the pool size based on production load can enhance performance further. This can be achieved through scripts or services that periodically review workload metrics (queue length, CPU, memory) to adjust pool sizes. However, excessive resizing can introduce overhead [4].

5. Asynchronous Call Improvements:
   Ensure asynchronous calls are properly implemented to maximize throughput while avoiding bottlenecks in subsequent stages (e.g., business processes or operations). Consider whether dependent components also require pooling adjustments [1].

6. Performance Monitoring:
   Regularly monitor the queues and system resources. Long or stuck queues can indicate performance issues, potentially highlighting when to scale pool size or address bottlenecks (e.g., external system delays) [5].

Try testing these ideas and adjusting settings incrementally for better insight into the optimal configuration for your workload requirements [1][2][3][5].

The issue you are encountering arises because the HealthShare FHIR Gateway is designed to be primarily read-only for interacting with a FHIR client. This means operations such as creating a new resource (e.g., Patient) using an HTTP POST request are not supported. Instead, data in the FHIR Gateway is loaded from the HealthShare Information Exchange (HIE) and can only be queried after being scoped to a specific patient session.

If you require write capabilities, you would typically operate on a standard FHIR namespace (not FHIR Gateway) or look into a workflow that involves converting FHIR data into the internal SDA (Source Data Architecture) used by HealthShare. This requires implementing a custom solution for handling FHIR data through the Edge Gateway production [1].

To have a Business Service (BS) that retrieves and saves an authorization token for use by a Business Operation (BO), here are the steps:

1. Create your BS to retrieve the token and store it securely, such as in a global or a data structure. For example:

   • Use ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient to retrieve the token.
   • Save the retrieved token in a globally accessible location (e.g., a global or a persistent data structure).

2. In the BO, make use of the token when firing off requests. You can use the AddAccessToken method of %SYS.OAuth2.AccessToken to attach the token directly to HTTP requests made by the BO [1][2].

3. For implementation:

   • In the BS, schedule a process to fetch a new token periodically and refresh it if expired.
   • In the BO, retrieve the stored token from your chosen location and include it in outgoing HTTP requests.

Here’s a simple BO implementation snippet for using the stored token:

Method MakeRequest() As %Status {
    Set httpRequest = ##class(%Net.HttpRequest).%New()
    set token = <retrieve the stored token>
    $$$THROWONERROR(httpRequest.SetHeader("Authorization", "Bearer "_token))
    $$$THROWONERROR(httpRequest.Post(<Your API Endpoint>, .response))
    Quit $$$OK
}

Ensure that your logic for saving and retrieving the token handles expiration and regeneration correctly for continuity.

To address the issue of failing to fetch the namespace list from the server in VS Code using the InterSystems Language Server extension, you can try the following steps:

1. Ensure you have correctly configured the server settings in your settings.json file, which should include the server name, namespace, and credentials. Below is a sample configuration for reference:

   {
      "objectscript.conn": {
          "server": "your_server_name",
          "ns": "USER",
          "active": true
      },
      "intersystems.servers": {
          "your_server_name": {
              "webServer": {
                  "scheme": "http", // or "https" depending on your server
                  "host": "your_host_address",
                  "port": your_port_number
              },
              "username": "your_username",
              "password": "your_password"
          }
      }
   }
   

   Replace your_server_name, your_host_address, your_port_number, your_username, and your_password with your actual connection details. Ensure that the namespace you are trying to connect to is available on the server and accessible with your credentials [1][2].

2. Verify that the namespace exists on the server. If the namespace you set in the configuration has been deleted or does not exist, VS Code may fail to fetch the list or connect. You can recreate the namespace temporarily on the server, which may help resolve the issue and allow you to switch namespaces via the UI [3].

3. Confirm that the web application api/atelier is correctly enabled on the server. If it is not properly configured, the connection might fail.

4. If the issue persists, try using the "Choose Server and Namespace" functionality in the ObjectScript Explorer view to manually select or update the namespace [4].

If none of these steps resolve the issue, seeking guidance in the InterSystems Developer Community might be necessary.

The issue you're encountering with <INVALID OREF> suggests that the identifier.value or target.MRN is not a valid ObjectScript reference (OREF) during the operation. This happens if the identifier is not properly initialized as an object. To address this issue, verify that identifier contains a valid OREF before trying to access its property value. You can do this using $ISOBJECT.

Here’s an example adjustment to your code:

while mrnIter.%GetNext(,.identifier) {
  if $ISOBJECT(identifier) && (identifier.system = "urn:oid:1.2.840.114350.1.13.172.2.7.5.737384.100") {
    set target.MRN = identifier.value
  } else {
    $$$LOGINFO("Invalid OREF for identifier or system mismatch")
  }
}

This ensures the loop only processes identifier objects that are valid and avoids errors when working with null or invalid OREFs [1][2][3].

To adjust a datetime by subtracting five hours or 18,000 seconds (5 hours * 60 minutes * 60 seconds) in an HL7 Data Transformation, you can use ObjectScript utilities designed for time manipulation.

1. Using ConvertDateTime function: InterSystems provides the ConvertDateTime() utility in Ens.Util.Time. Example:

   Set NewDate = ##class(Ens.Util.Time).ConvertDateTime("20201224161922", "%Y%m%d%H%M%S", "YYYYMMDDHHMISS")
   

   This function allows you to manipulate date formats and apply operations on datetime values [1].

2. Time zone library: There's also a specialized library for converting and handling time zones with both HL7 formatted times and adjustments. An example of subtracting a specific duration (5 hours in your case):

   Set datetime = "20201224161922"
   Set newDatetime = ##class(Ens.Util.Time).SubtractSeconds(datetime, 18000) ; Subtracting 18,000 seconds (5 hours)
   

   This will yield 20201224111922 [2].

These approaches can be used directly in your transformation logic for accurate date-time operations. If using time zones or further functionalities, refer to the utilities within InterSystems' interoperability tools or libraries [1][2].

To make the Ens.ScheduleHandler alert on error, you need to configure your Ensemble production appropriately. Ens.ScheduleHandler interacts with Ens.Alarm and other components to manage scheduled start and stop times for production items.

To enable alerts, you might employ the Ens.Alert or similar mechanisms already available in InterSystems IRIS/Ensemble systems. You could configure the components linked to Ens.ScheduleHandler and trigger alerts based on specific error scenarios.

Messages between Ens.ScheduleHandler and Ens.Alarm ensure that components are started/stopped according to schedules. Errors or disruptions during this process could be monitored and alerts set up by designing rules in your systems for such sessions. This process uses the ensemble messaging system, which may require setting the proper parameters to retain scheduling-related messages and avoid purging them preemptively [1].

If you intend to integrate more robust error handling, consider subclassing relevant components and adding mechanisms to send alerts upon encountering specific exceptions, which might require adjustment to adapter settings or creating custom notification rules [2][1].

The error arises because OpenID Connect is only supported by InterSystems IRIS OAuth2 for the authorization code and implicit grant types. According to the system's design, OpenID Connect scopes (like "openid" required by your FHIR server) are not intended to be used with client credentials or password grant types.

This check is implemented to ensure that features specific to OpenID Connect, such as ID tokens, are excluded when using grant types that don't fit its typical use cases. OpenID Connect is primarily used to authenticate users via user interaction, which is not the scenario with client credentials or password grant types. These grant types are designed for machine-to-machine communications where user authentication is not involved [1][2].

Currently, you may need to consult the third-party FHIR and Keycloak server configurations to find a workaround. For information on supported scenarios, please refer to the OAuth 2.0 and OpenID Connect documentation [1][2].

To import date-formatted columns from an Excel file using ObjectScript with Python, you can utilize the Python openpyxl library for handling Excel files. When working with date values from Excel, here are key considerations:

Handling Dates

1. When reading cells in Python using openpyxl, the library retains the Python datetime objects for date-formatted cells. You may need to convert these to an appropriate format in ObjectScript.

2. Example of accessing a date cell:

   Set pyCell = pySheet.cell(row, column)
   If pyCell."is_date"() {
      Set dateValue = pyCell."value"
      // Example conversion using ObjectScript: Format the dateValue appropriately
      Set formattedDate = $ZDATE(dateValue, 3)  // Depending on desired display format
   }
   

3. Check the "is_date" property to identify whether the cell contains a date value.

4. Formatting dates in ObjectScript can be done using $ZDATE or $ZDATEH functions, which allow you to control the format and convert dates from internal date formats to display formats. $ZDATE supports multiple formats listed in the documentation, such as YYYY-MM-DD (format 3) or DD/MM/YYYY (format 4) [1][2].

Example Workflow

• Load the workbook and access the active sheet using load_workbook.
• Iterate through rows and columns, check the cell type, and convert date values using the ObjectScript $ZDATE function.

This should address the issue of correctly processing and importing date-formatted cells from Excel files into your ObjectScript environment [3][4][1].

The scenarios mentioned for orphaned HL7 messages such as purging without selecting "Bodies Too," code creating or saving a message and not sending it, and BPL errors, are significant contributors. However, additional causes include:

1. Negative ACKs in Operations with specific Reply Action Codes: If an operation receives a negative acknowledgment (ACK) and its Reply Action Codes are configured to process as "Completed," the ACK is stored but does not create a Message Header or entry in the IOLog. This can cause orphaned messages without a clear straightforward solution, as Reply Action Codes in the Business Operation might be creating these orphans intentionally under the "Completed" status for specific operations [1].

2. Mismatch with Schema: When external systems send an ACK that does not match the expected schema, the ACK is stored but fails to create a Message Header or IOLog entry. Correcting the schema for the ACK resolves this [1].

For identifying orphaned messages, use SQL queries such as the following:

SELECT HL7.ID,HL7.DocType,HL7.Envelope,HL7.Identifier,HL7.MessageTypeCategory,HL7.Name,HL7.OriginalDocId,HL7.ParentId, HL7.TimeCreated
FROM EnsLib_HL7.Message HL7
LEFT JOIN Ens.MessageHeader hdr
ON HL7.Id=hdr.MessageBodyId
LEFT JOIN Ens_Util.IOLogObj ack
ON HL7.Id = ack.InObjectId
WHERE hdr.MessageBodyId IS NULL AND ack.InObjectId IS NULL

This lists messages missing from Ens.MessageHeader or unreferenced in Ens_Util.IOLogObj [2].

To avoid orphans:
- Always forward created message bodies and use APIs like SendRequestSync or SendRequestAsync which save the message automatically before sending.
- For purging orphan messages programmatically, tools like CleanupSet in the ENSDEMO database can help perform a deep purge [2].

For issue 1 specifically, revisiting the operations' Reply Action Codes settings or coding practices to ensure headers and IOLog entries are created correctly may offer insights into resolution. This approach requires careful testing to match the required configurations and handle exceptions without creating orphans [1][2].

The $PRINCIPAL system variable contains the ID of the principal device for the current process and operates like $IO. The WebTerminal sessions seem to behave differently because $PRINCIPAL in WebTerminal defaults to a device /./nul, which is a non-terminal device, unable to access terminal-specific features like ^%SYS.PMODE. This contrasts with Management Portal direct terminal sessions where $PRINCIPAL is |TRM||$J, mapping to the terminal feature [1].

The discrepancy arises because WebTerminal emulates a basic I/O environment where $PRINCIPAL is set to redirect I/O operations in a generic way, which limits compatibility with certain programmer-mode features. Unfortunately, this setup affects terminal functionalities reliant on $PRINCIPAL. Addressing it might involve either altering WebTerminal's configuration to simulate terminal I/O or finding alternative approaches for terminal-dependent tasks.

The $PRINCIPAL issue can also interact with how input/output devices are handled through $SYSTEM.Process.ReDirectIO() and similar parameters in WebTerminal [2].

Yes, filename capture during a Business Process (BPL) process and setting it to MSH-6 in an HL7 message can be performed as described below:

1. Access the Original Filename: To access the original filename in BPL, you can use the property request.OriginalFilename if the message contains the Ens.StreamContainer object, which holds metadata like the original filename [1].

2. Modify the HL7 Message: Using a DTL transformation within the BPL, you can set the value of MSH-6 in the HL7 message to the retrieved filename:

   • Create a Data Transformation (DTL) that modifies the HL7 message.
   • Use the context variable or the filename in the source (e.g., context.Filename) and assign it to the corresponding field target.{MSH:6} in the target HL7 structure [2][3].

3. Sequence of Actions:

   • Retrieve the filename from the incoming data and store it in a context variable within the BPL.
   • Pass the HL7 message and the context variable to the DTL.
   • The DTL should include logic to map the context variable (e.g., context.Filename) to target.{MSH:6}.

This approach ensures the filename is correctly embedded in the MSH-6 segment of the HL7 message [1][3].

If further customization or examples are required, please share more details.

Sources:

You can implement the functionality to extract the first six characters from the filename and insert them into MSH-6 in multiple HL7 messages within HealthConnect. A custom solution using InterSystems HealthConnect tools would be necessary for this specific task. Below are some resources to consider:

1. Custom File Adapter Approach: You can create a custom adapter extending EnsLib.File.OutboundAdapter, allowing dynamic file path and filename manipulation based on HL7 message content or input filename. For your case, you can pull the filename and extract its first six characters which can then be stored or manipulated:

   • Use object methods available for stream handling and ensure you integrate proper lookup or extraction logic for filenames from stream objects [1].

2. State Machine Handling: You can design a method to walk through file streams. Implement a state machine approach to process segments, extracting the desired filename's prefix (first six characters) and inserting them into MSH-6 of each HL7 message. This can be achieved while iterating through HL7 messages in the input file stream [2].

3. Dynamic Parsing within a Custom Service:

   • Modify or create a custom service derived from EnsLib.HL7.Service.FileService. This service can preprocess filenames from the incoming file before parsing HL7 messages. From the extracted prefix of the filename, you can dynamically update the content of MSH-6 using message manipulation APIs [2][3].

4. Use DTL to Transform Messages: You can use Data Transform Language (DTL) within HealthConnect:

   • In your DTL transformation logic, access the filename prefix and set it for MSH-6 dynamically. This requires implementing a preprocessing stage to extract the filename prefix into a variable and then map or assign it within the transformation logic when processing each HL7 MSH segment [4].

5. For handling multiple HL7 messages with multiple MSH segments:

   • Parse the file stream to count or iterate over multiple messages and ensure data insertion at precise positions (such as MSH-6). Looping constructs within custom classes or using EnsLib HL7 utilities and function sets help in processing multiple records [3].

Reference the provided examples for functional customization in classes and follow the guidelines to achieve desired results [2][3][4][1].
