The issue arises because Python's print statements and IRIS's ObjectScript write statements operate on different devices, causing your custom Buffer class in ObjectScript to not capture these outputs. To address this, you can redirect Python's output to a stream more integrated with ObjectScript. Here are some possible solutions and approaches:

1. Using TCP Device for Output Redirection:
   Set up a TCP listener to capture the output from Python and use the write command for ObjectScript to send data. This approach ensures Python's output is redirected to a specific listener that can be handled by your Buffer.

   Example:

   • On the ObjectScript side, configure the TCP device:
     objectscript
open "|TCP|4":("127.0.0.1":4200::$CHAR(3,4)):10
use "|TCP|4"

• From Python, write to the same device:
  python
import socket
TCP_IP = '127.0.0.1'
TCP_PORT = 4200
BUFFER_SIZE = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
s.send(b"Python print statement redirected!")
s.close()

  This setup will unify Python and ObjectScript outputs for capturing [1].

2. Custom Python Output Stream:
   Implement a custom output stream in Python to intercept the sys.stdout and redirect everything to an ObjectScript-compatible format:

   import sys
   class CustomStdout:
      def write(self, text):
          # Implement logic to capture and redirect text to ObjectScript
          print("Redirected:", text)
   
      def flush(self):
          pass
   
   sys.stdout = CustomStdout()
   

   You can use CustomStdout to marshal Python's print output to your Buffer [1].

3. Combining Both Approaches with the iris object:
   Utilize the IRIS Python SDK to directly invoke ObjectScript's methods that align well with your Buffer functionality:

   import iris
   iris.pyrun('write("Captured directly into Buffer")')
   

   This ensures a direct capture of Python's outputs into ObjectScript-compatible streams [1].

These configurations will help you unify Python and ObjectScript outputs, enabling your Buffer class to successfully capture statements irrespective of their source.

Creating a %Installer.Manifest file from the current state of an InterSystems IRIS instance and managing its changes is theoretically possible using InterSystems tools, but no specific documentation references a generator or exporter tool for this purpose. Here are insights and possible steps:

1. Using an Installation Manifest:
   A manifest class in InterSystems IRIS allows you to define and configure specific configurations declaratively. You can create a custom class with an <XData> block specifying the attributes and methods necessary to set up namespaces, CSP applications, roles, and databases. For example, <Namespace> and <Database> tags may be used to set up namespaces and databases corresponding to your current environment. The setup class method typically uses %Installer.Manifest for execution [1][1].

2. Tags and Variables in Manifest:
   You can dynamically generate configuration setups using variables embedded in tags like <Manifest>, <Namespace>, and <Database>. These tags provide flexibility to replicate environment setups declaratively. ObjectScript expressions can also expand values during execution [1].

3. Manual Definition of Components:
   Specific details of your IRIS instance, such as namespace settings, security roles, and CSP applications, must be extracted manually or programmatically. Consider using commands such as MERGE or leveraging other APIs documented for IRIS to extract and replicate elements [3][4][5].

4. Management of Logs and Messages During Deployment:
   The setup method of %Installer allows directing messages and logs for deployment tracking. These can be stored externally for audit trails or debugging during environment replication [1].

5. Export and Automation Possibilities:
   Although building a fully automated generator is not described in the current documentation, the modular nature of manifest definitions, provided examples, and utilities for setting up elements can guide constructing your “auto-export tool” using ObjectScript or related automation.

For partial tools or scripts:
- Referencing %Installer.Manifest and using its methods for defining databases, namespaces, and roles programmatically can be an initial approach.
- Engaging with the Developer Community could provide tailored solutions or open-source implementations shared by other developers [1][5].

If you need guidance on creating specific components within %Installer.Manifest, feel free to ask!

To calculate the difference in hours (with decimals) between two %TimeStamp values in ObjectScript, you can use the $ZDATETIMEH function to convert the timestamps into $HOROLOG format, and then calculate the difference using appropriate arithmetic. Here is an example approach:

Code Implementation

ClassMethod CalculateHourDifference(startTime As %TimeStamp, endTime As %TimeStamp) As %Float
{
    // Convert start and end times to $HOROLOG format
    Set startTimeH = $ZDATETIMEH(startTime, 3)
    Set endTimeH = $ZDATETIMEH(endTime, 3)

    // Calculate the difference in days and seconds
    Set dayDiff = $PIECE(endTimeH, ",", 1) - $PIECE(startTimeH, ",", 1)
    Set timeDiff = $PIECE(endTimeH, ",", 2) - $PIECE(startTimeH, ",", 2)

    // Combine the difference into hours
    Set totalHours = dayDiff * 24 + (timeDiff / 3600)

    Return totalHours
}

Explanation

1. $ZDATETIMEH(timestamp, precision) converts a %TimeStamp into $HOROLOG format with the precision value 3 for best compatibility [1][2].
2. $HOROLOG format consists of two parts: the number of days since 31 Dec 1840 and the number of seconds since midnight of the current day.
3. By calculating day and second differences separately, you can then convert the total time difference into hours.

Example

Using your provided timestamps:

Set startTime = "2024-07-12 08:30:00"
Set endTime = "2024-07-12 15:15:00"
Write ##class(YourClass).CalculateHourDifference(startTime, endTime)
// Output: 6.75

This approach ensures precision and clarity while working with timestamps in ObjectScript. [1][2]

Sources:

a) The <EXTERNAL INTERRUPT> error might occur due to an operation that has been interrupted by the system, typically caused by a timeout, or a forced user action or process interruption. This happens when the code execution is halted by an external signal like a system-level command. For more complex handling, implement proper timeout handling or consider logging additional details to diagnose such occurrences further [1][2][3].

b) To view the .INT or .MAC code associated with .OBJ, you can utilize debugging commands or tools within the Cache platform. Using the ObjectScript terminal, invoking debugging frameworks like %SYS.Debug could help. However, ensure that debugging permissions are appropriately assigned. Consider methods or tools that provide insights into such .OBJ routines or consult specific debugging best practices documentation applicable to your Cache release version. Without exact tools defined, specific steps can sometimes be ecosystem-managed system [3][4][5].

Further challenges in processing may arise from mismatches of commands - swizzle directions, context pointer handling errors-hands values. Advised debugging tools , e.g invoke"""

There is no direct documentation or feature in InterSystems Package Manager (IPM) that specifically addresses handling System Default Settings for CI/CD pipelines. However, here are potential approaches based on available information:

1. System Default Settings: These settings simplify management of environment-specific configurations, such as file paths, port numbers, etc., and can be exported/imported using methods like %Export and %Import. It is advisable to integrate these methods into your pipeline processes to automate these tasks [1][2].

2. Custom Automation: While not directly tied to IPM, you can use tools or scripts, such as the GetSettingsFromProduction method, to gather and setup System Default Settings efficiently during the deployment process. This method allows filtering specific settings and automating their migration to the system defaults table [3][4].

3. Source Control: System Default Settings can be exported and tracked in version control. Each branch or CI/CD environment can include specific setting files, which can then be applied programmatically during deployment [2].

If Invoke scripts are acceptable for your case or specific automation needs, they could wrap around these export/import or automation methods to ensure smooth integration without extending IPM itself. For completely eliminating custom solutions, consider submitting a feature enhancement request on InterSystems Developer Community.

1. To list a user and their properties, including roles, you can use ObjectScript commands with the Security.Users class in the %SYS namespace. An example of listing the properties of a user is:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    ZWRITE properties
}

This retrieves the user's properties into a reference variable and displays them [1][2].

2. To add a user and set their properties, including roles, you can use the Create method of the Security.Users class. For example:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET properties("FullName") = "New User"
SET properties("Password") = "securepassword"
SET properties("UserRoles") = "%Developer,%Operator"
SET status = ##class(Security.Users).Create("NewUser", .properties)
IF $$$ISOK(status) {
    WRITE "User created successfully."
}

This creates a user with specified roles and other details [1][2].

3. To set a user's password, you can use the Modify method to update the relevant property, as in:

NEW $NAMESPACE
SET $NAMESPACE="%SYS"
SET status = ##class(Security.Users).Get("Username", .properties)
IF $$$ISOK(status) {
    SET properties("Password") = "newpassword"
    SET status = ##class(Security.Users).Modify("Username", .properties)
    IF $$$ISOK(status) {
        WRITE "Password updated successfully."
    }
}

This updates the user's password [1][2].

The use of a separate license server in an HA mirroring environment, such as hosting it on the arbiter machine, might alleviate licensing issues during failovers. Below are key considerations regarding licensing and communication between mirrored servers and users:

1. Role of ISCAgent and Arbiter: The ISCAgent on arbiter machines assists the failover process by ensuring communication reliability between mirror members, even during failovers [1][2]. It does not directly manage user sessions but enables seamless failover between mirrored servers.

2. Licensing Impact on User Sessions: The documentation does not explicitly mention whether adding a license server to the arbiter would prevent users from logging back in after failovers. However, setting up proper failover mechanisms and ensuring that the ISCAgent process is correctly configured on all mirror members can help maintain application continuity during failover [1][2][3].

3. Configuring ISCAgent for Communication: The agent can be configured using /etc/iscagent/iscagent.conf to define the server port and interface. Proper configuration of this communication layer can strengthen connections between mirrored members [3].

Without further specific documentation on the license server itself, you might need to test or consult with support to understand potential benefits or issues before adopting such a setup.

CSP pages in InterSystems IRIS do include mechanisms to interact with JavaScript asynchronously using features like "HyperEventHead()" and "HyperEventCall()". These functionalities allow the execution of server methods triggered by client-side JavaScript, making it possible to update the UI without refreshing the page. However, it appears that the dynamic invocation of server-side code is managed through mechanisms such as cspHttpServerMethod, which relies on specific server support rather than JavaScript's native Promise or async/await functionalities [1].

If you need fully asynchronous JavaScript futures support, it might require an alternative to CSP, such as modern JavaScript frameworks (e.g., Vue.js, React) communicating via REST APIs, as suggested in discussions about the evolving practices for frontend-backend integrations with IRIS [2][3].

Sources:

The "ErrST+6^%ETN" error message you encountered within %ETN suggests that the application encountered an error during the execution of the error trap utility %ETN. The utility is designed to save information about an error, including the execution stack, job state, and variable values, to the application error log. However, since the error occurred within %ETN itself, detailed error logging was not possible in this instance [1][2][3].

To address errors encountered during the use of %ETN:
1. You can view the application error logs using either the Management Portal or the ^%ERN utility to examine other related logs. This may provide additional clues about the failure [1][4].
2. Consider setting up the $ZTRAP variable to handle or analyze the error before invoking %ETN. For instance:
ObjectScript
SET $ZTRAP="^%ETN"
This ensures that any errors occurring are captured and logged by %ETN [1][5].

Lastly, while dealing with unusual date entries (e.g., "01/06/1841"):
- Review and filter error logs using the Management Portal or ^%ERN, specifically searching by date or error substrings [4][6].
- Check if any system or user inputs inadvertently set such dates during logging or processing activities, as they may be erroneous.

Sources:

To log an exception to the Application Error Log in InterSystems IRIS, you should use the %Exception.AbstractException.Log() method. Typically, this is done within the CATCH block of a TRY-CATCH construct. Here is an example in ObjectScript demonstrating this approach:

TRY {
    // Code that might throw an exception
} 
CATCH ex {
    // Log the caught exception to the Application Error Log
    DO ex.Log()
}

This method ensures that the details of the exception, including its type and properties, are recorded in the namespace-specific Application Error Log [1].

Sources:

The error "Attempt to access a protected database" occurs due to a lack of necessary access privileges. In the context of mirrored databases like the ROUTER database on your T2 server, this error typically indicates that the user or process trying to access the database does not hold permissions required for operations on that database.

To resolve this:
1. Ensure that the user or process attempting to mount or access the database on T2 has the appropriate privileges assigned to the database resource. For the database, the relevant permissions are controlled by the associated database resource, such as %DB_. Users must have "Read" permissions to access data and "Write" permissions for modifications [1].

2. If the database has no explicitly defined database resource, it defaults to the %DB_%DEFAULT resource. Ensure that the roles or users interacting with the database have the necessary privileges associated with the %DB_%DEFAULT resource [1].

3. You can verify user privileges by using methods such as $SYSTEM.Security.Check(resourceName, privilegeName). For example:

   WRITE $SYSTEM.Security.Check("%DB_ROUTER", "READ")
   

   This will return 1 if the process has Read permissions on the %DB_ROUTER resource or 0 otherwise [1].

In summary, the error is a result of privilege misconfigurations, and you need to audit and adjust user or process privileges for the concerned database or resource.

To address the behavior of the EnsLib.TCP.TextLineOutboundAdapter, where it expects a terminator and times out if none is provided, you have a few options:

1. Explicitly Set a Terminator:
   You can set the Terminator property of your adapter to a character or sequence of characters that you might expect (though you already attempted $c(10) or $c(13) without success). According to the documentation, this property supports multi-character strings [1].

   Example of code customization:

   Class Custom.TCPAdapter Extends EnsLib.TCP.TextLineOutboundAdapter
   {
      Property Terminators As %String [ InitialExpression = "" ];  // Clear terminators if none should apply
   }
   

2. Custom Adapter or Manual Reading Logic:
   If the responses truly do not include terminators and cannot be adjusted on the third-party side, you might need to implement your own logic for receiving data. This involves overriding the necessary methods in the adapter to change how responses are interpreted — possibly using a timeout or a custom data parse handler to disconnect terminator reliance.

   Example of using a manual read logic:

   Method ReadWithoutTerminator()
   {
      // Example of binary mode read without terminators
      set device = "|TCP|Host:Port"
      open device:("R")
      use device
      read x:Timeout
      quit x
   }
   

3. Binary Stream Mode:
   You could configure the adapter to operate in binary mode (/IOT="RAW"). Manually process the data reading and assembly based on expected response patterns or sizes [2][3].

   Example:

   set device="|TCP|7000"
   open device:(host:port:"M")
   use device:(/IOT="RAW")
   read response:Timeout
   

You should consider adapting the built-in EnsLib.TCP.TextLineOutboundAdapter or creating a subclass of it for better control over edge-case behaviors. [4][2][3]

The code you used (set DOB=$zd(paper.PAPERDob,15)) most likely returns a two-digit year by default because $ZDATE defaults to using two-digit years for certain ranges unless a different option is explicitly set. For years like 1995 or 1999, $ZDATE shows the last two digits as 95 or 99. To display the full year, use the YearOpt parameter.

You can modify the code to explicitly specify four-digit years. Use the YearOpt argument in $ZDATE. The following example forces four-digit years:

set DOB=$ZDATE(paper.PAPERDob,15,,,4)

• $ZDATE(hdate,dformat,monthlist,YearOpt) allows you to specify YearOpt, where:
  • 4 ensures the year is displayed as four digits.
• Format code 15 corresponds to DD/MM/YYYY [1].

If your issue persists, ensure your locale settings align correctly with four-digit years expected in the display [1].

The issue you're encountering with $ZF(-100) and the <NOTOPEN> error likely stems from the use of the "/SHELL" flag. For $ZF(-100) to execute commands with this flag, it may encounter file access issues or problems with setup for standard input/output redirection. Specifically, the <NOTOPEN> error can occur if:

1. A file specified for input/output redirection cannot be created or opened.
2. The command cannot be started as requested.

Ensure the following:
- Verify that there are no issues with permissions or availability for any file or resource specified with /STDIN, /STDOUT, or /STDERR flags. These flags control input/output redirection [1].
- When invoking the shell with /SHELL, ensure that the OS command's path is accessible, and there are no syntax errors in the options [1][2].
- Avoid mixing syntax such as redirection operators >> with /STDOUT flags as they might create conflicts [3].

You can resolve this error by ensuring:
1. Necessary permissions are granted to create or open files for redirection.
2. The command and its arguments are validated properly without conflicting flags or operators.
3. Avoid redundant configurations like using /STDOUT flags along with output redirection operators in the command.

For example, to execute a common Windows directory listing command with redirection, use:

set status = $ZF(-100, "/SHELL", "dir", "")
w !,"Status: ", status

Ensure you do not accidentally specify both /STDOUT redirection and shell redirection (>> inside the command). Adjust based on the exact use case and configuration [1][3].

It seems that you're encountering an issue with mapping the FHIR response inside FHIRModel.R4.Patient. Based on provided references, here are some relevant approaches to address this:

1. When working with FHIR responses, it's essential to use the appropriate method to map and handle the response. Utilize the HS.FHIR.DTL.vR4.Model.Resource.Bundle.FromJSON method for parsing the JSON stream of your FHIR response. This method converts the JSON stream into a class object that you can navigate programmatically:

   Set BundleObject = ##class(HS.FHIR.DTL.vR4.Model.Resource.Bundle).FromJSON(pHttpResponse.Data, "vR4")
   

   After converting to a Bundle, you can explore its entry elements to locate and manipulate the Patient resource [1].

2. If you're considering transforming FHIR responses into SDA (Summary Document Architecture), you can use HS.FHIR.DTL.Util.API.Transform.FHIRToSDA3 for converting FHIR messages to the SDA structure. However, note that this specific transformation expects certain configurations and may involve handling additional fields that might not directly belong to a FHIR request [2][3].

3. If the Patient resource isn't being fully populated, validate the FHIR payload against the expected schema. Ensure all mandatory fields and structures align with the FHIRModel.R4.Patient class requirements. In certain cases, mapping issues occur due to missing fields or format mismatches.

4. Lastly, the Quick Stream ID might also be relevant for identifying and processing the incoming FHIR response correctly. Ensure you're interacting with the response appropriately:

   Set quickStreamIn = ##class(HS.SDA3.QuickStream).%OpenId(tResponse.QuickStreamId)
   Set responseObject = ##class(%DynamicObject).%FromJSON(quickStreamIn)
   

These approaches can help debug and refine your handling of the FHIR Patient resource. If further clarification on specific methods is needed, let me know! [4][5][1].

When setting up a web application using Delegated Authentication via InterSystems IPM and ZAUTHENTICATE, you need to address the issue of automatically enabling Delegated Authentication because it doesn't appear to work directly through module.xml. Here's how you can resolve this systematically and implement this authentication mechanism:

1. ZAUTHENTICATE Routine Setup:

   • Create a custom ZAUTHENTICATE routine in the %SYS namespace. This serves as the main entry point for implementing your authentication logic. Example:
     objectscript
ZAUTHENTICATE(ServiceName, Namespace, Username, Password, Credentials, Properties) PUBLIC
{
set tRes=$SYSTEM.Status.OK()
try {
set Properties("FullName")="OAuth account "_Username
set Properties("Username")=Username
set Properties("Roles")=Password
} catch (ex) {
set tRes=$SYSTEM.Status.Error($$$AccessDenied)
}
quit tRes
}
     The routine verifies the passed credentials and sets user properties like Roles and FullName as required [1][2].

2. Enable Delegated Authentication Globally:

   • Navigate to System Administration > Security > System Security > Authentication/Web Session Options.
   • Select the "Allow Delegated Authentication" checkbox and save the configuration. This step ensures delegated authentication is enabled for the entire instance [1][2].

3. Enable Delegated Authentication for Specific Applications:

   • In your Web Application (module.xml), include the AutheEnabled field to configure delegated authentication:
     xml
<WebApplication
Name="/${namespaceLower}/api"
NameSpace="${namespace}"
DispatchClass="pkg.isc.genai.rest.Handler"
MatchRoles=":%All"
AutheEnabled="#{$$$AutheDelegated}"
Recurse="1"
CookiePath="/${namespaceLower}/"
/>
     This marks the authentication type for the app as "delegated" [1][2].

4. Manually Adjust Authentication Options (as a workaround):

   • If you still find that the Delegated checkbox is not appearing or operating via the SMP, manually ensure that the Web Session Options page has the necessary Delegated option enabled [1].

5. Automate Delegated Authentication through ClassMethod:

   • To automate enabling Delegated Authentication, write an ObjectScript ClassMethod that sets the required configuration programmatically. For example:
     objectscript
ClassMethod EnableDelegatedAuth(applicationName As %String) As %Status
{
set tApp = ##class(Security.Applications).%OpenId(applicationName)
if tApp '= "" {
set tApp.Delegated = $$$YES
quit tApp.%Save()
}
quit $SYSTEM.Status.Error($$$GeneralError, "Invalid application name.")
}
     Call this method in your setup process to apply the delegated setting directly [1].

6. Testing and Debugging:

   • Verify if ZAUTHENTICATE is being called during login attempts.
   • Use the audit log for %System/%Login/LoginFailure events to diagnose any authentication issues [1].

By establishing the proper backend with ZAUTHENTICATE and leveraging programmatic controls for system configurations, you can circumvent limitations in module.xml to enable Delegated Authentication seamlessly. [1][2]

To assign temporary variables within a foreach loop in ObjectScript, you may consider alternatives that enhance readability and maintainability:

1. Using Macros for foreach Iteration:
   You can define and use macros for looping over arrays and performing actions on each element. A macro can abstract the repetitive code required for array traversal. For example:

   ##; Macro definitions
   #define foreach(%key,%arr,%do) set %key="" for  set %key=$o(%arr(%key)) q:%key=""  do %do
   

   Example usage:

   #include ZFOREACHMACRO
   test $$$foreach(key,^rcc,show)
      quit
   show zwrite @$zr,!
      quit
   

   This approach simplifies the loop logic and makes it more modular [1][2].

2. Extended Command:
   Another option is creating an extended command ZZFOREACH for iteration. This allows deployment across namespaces and provides flexibility such as starting at a specific subscript or reversing the direction. Example command definition:

   ZZFOREACH(%par) public {
      set %par=$lfs(%par,";")
      new %array,%do,%fwd,%key,%val
      set %array=$lg(%par,1),%do=$lg(%par,2),%fwd=$lg(%par,3),%key=$lg(%par,4)
      if '%fwd set %fwd=1
      if %key]"" set %key=$o(@%array@(%key),$s(%fwd<1:-1,1:1))
      for  set %key=$o(@%array@(%key),%fwd,%val) quit:%key=""  do @%do
      quit 1
   }
   

   Example usage:

   DEMO>zzforeach "^rcc;show^dump(%array,%key,%val)"
   ^rcc(1) = 1
   ^rcc(2) = 2
   ^rcc(3) = 3
   ^rcc(4) = 4
   ^rcc(5) = 5
   

   This method condenses the loop logic and embeds control features [1][2].

3. Using the ObjectScript foreach Library:
   ObjectScript libraries such as the one in Foreach's GitHub repository enable modular iteration. The library supports dynamic arrays, objects, and other constructs. The syntax for using this is as follows:

   USER>set YOUR_VARIABLE = ["sample","data"]
   USER>do ##class(Iteration.Loop).Foreach(YOUR_VARIABLE,"METHODNAME")
   

   Inside the method (METHODNAME), actions for each element can be defined:

   ClassMethod METHODNAME(pMes) As %Status {
      write pMes, !
      return $$$OK
   }
   

   This library provides flexibility for defining custom methods for element handling [3].

These solutions provide alternatives to for-each loops in ObjectScript that improve code readability and may allow variable assignments during iterations, adhering to your goal [1][3][2].
