Hi,

We have a global with 65 million entries. All we are doing is just iterating through each entry to find out the total no of entries. It is currently taking 110 minutes. Is this something normal? What can we do to speed up this process? Below is the program for just iterating each entry in the global.

s sub=" ,count=0
f{
s sub=$o(^YYY(sub)) q:sub=""
s count= count +1
}
w!, "Total Count:"_ count

we are looking at replacing our VMS system with Linux :-( yes a sad day!

now the question has become should we go with Intel or AMD. personally I think Intel is the way to go for several reasons.

has anyone seen or heard of an AMD being slower or there is a definite performance of one over the other.

thanks for your feedback.

first our current environment which will be copied over to the new platform

Our application has a ZEN report that accepts a sorting parameter and a fundraiser parameter. Sorting tells us which order the pages are to be in and the fundraiser limits the data shown (e.g. which user has requested the report)

$zu(96,9) Not working

Suppose you have routine ^A loaded in your partition in programmer mode and you call routine ^B. Routine ^B finds the value of $ZU(96,9) which should be the calling routine.

But $ZU(96,9) now returns null, as does $SYSTEM.Process.CallingRoutine()

Works on 2018.1.7 but not 2018.1.8

$ROLES= %All on both systems

More precisely I have line label ZZPP in ^%ZLANGC00 which needs to identify the original routine in the partition and do some work on it. When I type ZZPP I get nothing on the later version. Here's the line of code:

I am trying to execute a program from within cache using a $zf call

S X=$ZF(-1,"C:\""Program Files (x86)""\Car-Part\Messaging\iCPM.exe")

For the sake of this post I changed it to open notepad

S X=$ZF(-1,"C:\Windows\notepad.exe")

If I call it directly from terminal notepad opens and all is happy.

If I add it to a program we use to run certain tasks once an hour or even every 10 minutes it will fire off notepad but it will be in the background.

I need to develop a tool to help to get what data is being consumed by a certain process, in order to get all data used to build an automated test scenario.

For example, some user process will pull data from ^GLOBAL(1)="dataString", ^GLOBAL(2)="dataString2", ^GLOBAL1(1)="data1String", ^GLOBAL2(4)="data2String4". Amidst all other data on these Globals, I will ignore everything that was not used in the user process, and get the specific keys used on it.

Hi,

I am using embeded python to utilize some pythonic library but i got a problem on my hand.

One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

Hide or make routines binary?

Sorry, somewhat of novice here, but how is a mac or a routine created into a binary or is there a way to hide your routines so that no other user can edit them? Like remove source code and have an executable?

I would like to do this MAC and CSP pages

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,
Richard

in Management Portal on Freespace screen there are links to compact and truncate a database.

Can these tasks be done programmatically? I have looked through documentation and dont see anything but I hope I just missed it.

Thanks,

This is for the veteran programmers out there (you know who you are; you started programming before date 60000).

I'm in the middle of updates for our system, and I've come across many $ZU() calls. Most of them are documented in the "Replacement List", but two are missing: $ZUtil(0) and $ZUtil(1).

I honestly don't remember what these are for (and I'm pretty sure I used them in code in a previous century), so if someone can tell me, great. If you can provide a link to a reference, better!

As always, I appreciate your help.

I have a question about how to modify a XData Block programmatically . Assume i have a impl.cls and there is a XData Block (like XData OpenAPI [ MimeType = application/json ]) in the impl.cls. In other class, can i write a fucntion to modify the context in the XData Block?

Ps: The document already show how to read the XData blcok, if i want to insert something into the block and save it back, how can i do this programmatically (eg write a method and read the block from other class, write something into the block and save it ) ??

Thanks

Hello community members!

I am trying to connect to Caché database from Azure data factory using ODBC connection. The aim is to read data from Caché and write it in Azure blob storage using copy activity. The ODBC connection is successful and i can see the Caché tables, but i'm facing an error while reading the table contents.

I'm getting the below error :

Hi all,
Does anyone have experience with obtaining logs from Caché databases and parsing them now? Please leave me a message.

I ask because my project involves some hospitals that used Caché when creating databases over 10 years ago. Currently, we cannot replace the database, but we need to check and parse the database logs from the Caché.

Thanks.

Our 3M Computer Assisted Coding system goes down on a regular basis for updates, the Applications folks like us to Disable the Business Operations when this happens and start them back up when they page the on-call person. The Business Operations have to be started in a sequence to guarantee that all the ADT being sent it processed before we start sending everything else.

Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.

We've implemented SAML authentication for our application where we are the service provider and various other entities are the identity providers. We've done successful connections with several identity providers including Okta, Duo Mobile, Ping Identity, and Azure. Validating the SAML response with signed assertions has been working great. Now, I am trying implement support for the SAML assertions in the response being encrypted for a new identity provider and struggling to understand procedurally how to go about this.

SELECT command within CSP

The program below works perfectly when I call it directly from the Terminal, however when I call it from within a CSP it does not work (It does not do the SELECT).

In the USER namespace, the program works both in the Terminal and on the CSP , but in another namespace it only works when called directly in the Terminal.

Debugging a SOAP web-client

Pointers please for debugging a SOAP web-client.

We have several clients in different productions all accessing a web-service. We are trying to add another client in a new production, and its not working. The messages between the relevant Process and the SOAP web-client Operation are the same in the working and the non-working productions. But the web-service is reporting an XML parsing error to the non-working production. Here's the error as reported in the SOAP web-client Operation...

Hello Guys,

Our cache application uses REST web services and handles single API request perfectly with response (response status and related data). But sometimes user sends multiple requests to the same API simultaneously ( ie, without waiting for the first to respond ), where one request will succeed (not necessarily the first) and the others will fail.

So, I need to handle the requests one by one after completing and sending the response for first request in the queue then process the next request and so on.

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:
