Hi @Eduard Lebedyuk , I was testing various options for configuring Apache (RHEL in my case), so I read the documentation (unbelievable, isn't it? 😂) and performed a number of tests, the I found this article  in the community and....I was kind of surprised because you suggest using CSP On/Off within a <VirtualHost> directive block.

I was surprised because the I excluded using <VirtualHost> directive block since the documentation suggests not using it (emphasis mine):

Note:

Although the Web Gateway supports the use of virtual host names in application access profiles, issuing Apache configuration directives to invoke the Web Gateway (that is, CSPFileTypes and CSP On/Off) within a <VirtualHost> directive block is not supported and will yield an error. In other words, you cannot enable the Web Gateway for the desired Virtual Hosts alone; you must enable the Web Gateway within the web server’s global configuration.

My my first thought was, well, this is a case where the documentation is wrong, sometimes it has happened.

At that point I was puzzled, so I tried using <VirtualHost> and, to my surprise, it worked!

Then I tried to validate my Apache config using "apachectl configtest" and:

[root@localhost conf]# apachectl configtest
[Sat Dec 21 17:22:39.632408 2024] [:warn] [pid 151005:tid 151005] Apache Configuration: CSP directive 'csp' detected in VirtualHost, only supported at default server level
[Sat Dec 21 17:22:39.632471 2024] [:warn] [pid 151005:tid 151005] Apache Configuration: CSP directive 'csp' detected in VirtualHost, only supported at default server level
[Sat Dec 21 17:22:39.632480 2024] [:warn] [pid 151005:tid 151005] Apache Configuration: CSP directive 'csp' detected in VirtualHost, only supported at default server level
Syntax OK

Not only is documented that using CSP On/Off within a <VirtualHost>, there is also some code implemented in CSPa24.so IRIS module to check for this and provide a warning message that says this is not supported.

Personally I'll avoid using CSP On/Off within a <VirtualHost> (at least) in production systems, unless some more info is found on this.

Out of curiosity, are these jobs listed form SQL using:

call Ens.Job_Enumerate()

and/or:

all Ens_Util.Statistics_EnumerateJobStatus('<YourBpNameHere>')

Is return supposed to return a boolean (0/1) or the non empty value of check1?

I'm asking because you write "will return false even for non-empty strings (due to conversion to integers for string prefixes)".

In general to check for not empty string (check1'="") is used.

If you need to return a boolean depending of empty/not empty, then you can use:

return (check1'="")

If/when you set KeepIntegrity to True, then ALL messages and message headers belonging to a session containing ANY message with status Created or Queued or Delivered or Suspended or Deferred are NOT deleted/purged, same goes for the headers (Ens.MessageHeader).

Since your is a test environment, it's (very?) likely having "messed" sessions that are not purged using KeepIntegrity  = True.
Sometimes even production systems do have sessions that are not purged using KeepIntegrity  = True.

While setting using KeepIntegrity  = True is "best practice" and prevent purging "uncompleted sessions", I suggest to run a purge with KeepIntegrity  = False with a (much?) longer DaysToKeep parameter, unless you do need/want to keep uncompleted sessions and messages for.....ever and ever.

For example, if you purge with KeepIntegrity  = True and DaysToKeep=30, you may run a second purge with KeepIntegrity  = false and DaysToKeep=90 (or longer) to purge really old messages belonging to "uncompleted" sessions.

When you purge that namespace with 30 day retention period, what value of "Purge only completed sessions" (was Keep Integrity in older versions) do you use?

Have you ever run the purge without including message bodies?

CONNECTION is a class parameter, to search all class parameters named CONNECTION with a specific value:

select parent from %Dictionary.CompiledParameter
where name = 'CONNECTION' and _Default='<your connection value to search>'

    Set objHttpResponse = objHttpRequest.HttpResponse
    If$IsObject(objHttpResponse.Data) {

        Set json = ""While ('objStream.AtEnd) {
            Set json = json _ objStream.ReadLine()
        }
    } Else {
        Set json = objHttpResponse.Data
    }
    Set httpStatus = objHttpResponse.StatusCode
    Write"Status: ", httpStatus, !
    Write"Response: ", json, !
}

I do not understand your question, can you please explain what you need to achieve?

%Net.HttpRequest class is used to create an HTTP request that is sent to the counterpart/endpoint and a response message is then received from the counterpart. How can you possibly generate a response that, by definition, has to be received from a remote system?

Clearly I'm missing something.

You may try with:

set tQuery="{ CALL dbo.SavePatientDetails (?) }"Set tParams=1Set tParams(1)=xmlContent
Set tParams(1,"SqlType")=$$$SqlVarchar; or 12 if macro does not resolveSet tSC = ..Adapter.ExecuteProcedureParmArray(.tResultSnapshots, .tOutputParms, tQuery,,.tParams)

For details see the SQL adapters documentation on Using Parameters.

Does it works if you use NVARCHAR(8000)?

My guess is that IRIS does not understand "MAX", if so...maybe there is a possible solution.

P.S.: what version of IRIS?

the ExecuteUpdate method expects the parameters to be passed in as an array

Actually, no, it expects  parameters as single/literal values.

The method ExecuteUpdateParmArray() expects parameters to be passed in as an array

I'm no expert on foreign tables, but maybe you can try:

select * from INFORMATION_SCHEMA.FOREIGN_TABLES

This should provide a list of defined foreign tables and the Foreign Server it uses.

I'm not sure how to get Foreign Server that have no tables defined.

Enrico Parisi · Dec 3, 2024 go to post

You can, this way:

Property Entry As list Of Entry(XMLPROJECTION = "ELEMENT");

Note that the tag is the name of the list property, not the list item.

What platform (Operating System) are you using for IRIS?

I think NTLM authentication is not available in IRIS for Linux.

To debug your issue I suggest to enable SOAP logging setting this two global node:

Set ^ISCSOAP("LogFile")="/path/to/yourlog/filename.log"
Set ^ISCSOAP("Log")="ios"

Values for ^ISCSOAP("Log") are:
"i" — Log inbound messages
"o" — Log outbound messages
"s" — Log security information.

Then call your SOAP service and check the log file for hints on the actual issue.

When finished debugging remember to turn it off with Set ^ISCSOAP("Log")="" or Kill ^ISCSOAP("Log")

In error handling code, when using SOAP and a <ZSOAP> error in triggered, the actual error status is contained in %objlasterror variable, so:

Set displayString = ex.DisplayString()
If displayString [ "<ZSOAP>" {
    Set displayString=$system.Status.GetErrorText(%objlasterror)
}

It's all documented, I cannot post documentation links because the documentation site it's not working for me at the moment.

According to the documentation, it's not possible exporting an object.

Edit: however, as pointed out by @Herman Slagman in the next post, it's indeed possible, I'm going to provide feedback to documentation team.

You can manually create the XML document using %XML.Writer, like:

set writer=##class(%XML.Writer).%New()
	set writer.Indent=1set writer.NoXMLDeclaration=1set status=writer.OutputToDevice()
	set status=writer.StartDocument()
	set status=writer.RootElement("XMLTest")
	set status=writer.Element("Id")	
	set status=writer.WriteAttribute("Attribute","D1949EE1-7D03-4666-9548-D1A949E10327")
	set status=writer.EndElement()
	set status=writer.EndRootElement()
	set status=writer.EndDocument()

The output of the above code is:

<XMLTest><IdAttribute="D1949EE1-7D03-4666-9548-D1A949E10327"/></XMLTest>

Having said that, what's your issue with the closing tag? Semantically there is no difference, any system should be able to handle both cases (with or without closing tag).

My guess is that your %var local variable array is in conflict with the code executed by the embedded sql.

As you may know % local variables have global scope, therefore should be used with caution, particularly when calling "other code", like embedded sql in your case.

If a global scope % variable is needed, is advisable to follow the documentation on Local Variable Naming Convention:

Variable names starting with the % character are known as “percent variables” and have different scoping rules. In your code, for a local percent variable, start the name with %Z or %z; other names are reserved for system use.

I suggest to change your variable to %zvar or similar, if you do not need global scoping, remove the leading %.

The time Veeam create a snapshot should be measured in seconds, not minutes!

If your server does not use/need any application guest processing (Oracle etc.), then in Veeam you can be disabled in "Application-Aware Processing Options" in the Backup Job configuration for your Suse IRIS server , "Disable application processing":

As @Timo Lindenschmid pointed out, you may consider backing up the secondary server.

In case you want to backup the primary, make sure to set mirror QoS appropriately.

Ciao Pietro,

difficult to tell without looking at the code.

Looking at the response my guess (bet?😉) is that your code  has some error processing and if "somewhere" an error status is returned, then the error processing is triggered and is returning the response you see, including headers etc.

Julian is correct, your code is inserting line breaks, remove the lines:

If 'pInput.AtEnd {
        Set tSC = tStream.Write($C(10))
        $$$TRACE("Adding terminator.")
    }

Since it's a vmware issue, not an InterSystems issue, I think you should ask vmware (now Broadcom).

What's the status returned by the Send() method of %Net.SMTP class?
I believe it should contain some info.
