Why we using double dot in cache?what is the use of it?

The code I'm researching loosely follows this flow:

1. My first callback
2. Black box
3. My second callback

I can modify 1 and 3 no problem but modifying 2 is difficult.

However I think that step 2 has some optimization problems, namely:

• instantiates lots of objects
• throws/catches lots of exceptions (not logged)

Is there a way to count these two metrics?

Hi ,

I am new to cache and I want to check with the experts to see if using the ctrl-c option while checking the list of databases is valid one or will it cause any issues. Below is my scenario

I use the below command to check the list of database

%SYS>do ^MSU

Greetings,

How do I organize a wildcard search with respect to a database search?

Example of what I am trying to do: s x=$o(^G("ABC","A*",x))

Trying to navigate through the ^G global for all occurrences of "ABC", and "A*" ("A"+wildcard) but I am new to M and don't know positively how to do this. Perhaps I don't use an "*" at all, rather; another convention altogether.

Please advise.

Thanks in advance for everyone's assistance.

Currently to check if the class is mapped I call:

ClassMethod IsClassMapped(class) As %Boolean

{
  set sc = $system.OBJ.GetClassList(.classes,"/system=0 /percent=0 /mapped=0")
  quit $data(classes(class))
}

And it works, but I'm interested if there is a simpler approach out there?

I need to know the current rss memory consumption. On earlier Cache versions I used this method:

set sc = ##class(%Net.Remote.Utility).RunCommandViaZF("smem -u cacheusr | grep cacheusr | awk '{print $6}'",,.rss)

It doesn't work because we use $zf(-100) on IRIS 2019.1.

New version:

I have a list

set list=$lb(1,$c(0),2)

How do I replace $c(0) with an empty element?

My list should look like this:

set list=$lb(1,,2)

I tried using $list but it either replaces the element with an empty string:

set $list(list,2)=""
zw list

Resulting in:

list=$lb(1,"",2)

Or removes the element altogether:

set $list(list,2,2)=""
zw list

Resulting in:

list=$lb(1,2)

Is there any Test Driven Development tool for Cache for the web development. If so can any one help me on this.

Thanks in advance.

I have a routing rule that processes messages from multiple customers. I would like to create some sort of flag or setting that I can toggle to indicate if a given customer is allowed to pass messages through the router. Should I use a registry entry, lookup table or something else? Which can be accessed from a routing rule and how?

Hi,

I'm new with writing Caché Objectscript so I need some assistance. I have XML which contains information like this:

   <cabinet>demo</cabinet>
   <eventType>IN</eventType>

</session>

I have a class representing this object as follows:

I am trying to apply a temporary time-limited key for our organization to a Cache Server that I built out a few weeks ago for testing purposes. When I navigate in the portal to activate a new license key, I get this "ERROR #8610: License keys are not accepted on a Single User (SU) platform."
