Interface Monitoring

Hi all,

I'm looking to set up monitoring for several interfaces. I understand that I can set an Inactivity Timeout. However, obviously there are messages coming through more frequently during certain hours than other hours.

Is there a way to set an Inactivity Timeout for each hour of the day instead of one value that is used all day long?

Best,

Erin

Hi,

I have a program that displays the current running processes to the screen. I need to have a program execute that display program and capture the results to a file. The display program does pause at the bottom of each page waiting for an 'enter' to go to the next page.

Note( the display program will not successfully compile on the current system but it does work)

Also - very, very new to Mumps.

Thanks,

Bob

Hello,

I'm trying to set Caché-Python Binding on Mac, but there is a problem.

I performed installation and configuration of Caché-Python binding module based on the manual (URL)
including setting of PATH and LD_LIBRARY_PATH in "bash_profile",
and they seems to be done successfully (there was no error in the process).

Hi guys!

As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).

1. Get it by as a property of an instance with "Object access":

ClassMethod GetPropertyForID(stId As %Integer) As %String

{

set obj=..%OpenId(stId)

return obj.StringData

}

2. Get it as a value of a column of the record with "SQL access":

Is there a way to have a context property be available across 2 or 3 different business processes? For example if I am setting a value in a context property within one business process and want to use the same context property in a second business process, is this possible? Is this something that can be done with the "Context Superclass"?

First time post, also a new Cache developer, hence the <Beginner> tag.

If our data has Predefined terms in a dictionary, and a user can add terms on their own, can the terms exist in different tables?

Lets call the tables "Terms" and the user data in "UserTerms".

If a third class definition has a property of "Term" can it not be either Terms or UserTerms?

I'm leaning towards using a Subclass strategy where the pseudo "Parent" (forgive me) is Dictionary.Term and the child is along the lines of Dictionary.Term.User

This is my first post, I have only been using Healthshare for a year.

We support multiple Healthshare test and development environments. We are trying to come up with the best solution for building an environment from scratch, as well as incremental updates. I am interested in hearing the pros and cons between using the Ensemble -> Export Production feature versus creating custom classes to do the install and setup.

I have one abstract class and several subclasses. All share one data/id global.

How can I get concrete class name from id (without opening the object)?

What I have so far:

write $p($lg(^DATAGLOBAL(<id>),1),"~",*-1)

It does the job, but is there a more official way?

Here's a simple indirection snippet. It fails with <UNDEFINED> error and I'm not sure why.

ClassMethod ind()
{
  kill info

  set active = 1
  set reactive = 2

  for i="active","reactive" {
    set info(i)= @i
  }

  zw info

  break
}

I'm getting this exception: <UNDEFINED>zind+5^test.Client.1 *active

I have a date in this format: "YYYY-MM-DD HH:MM:SS+HHMM" how can I convert it to UTC?

write $zdth("2018-02-01 00:00:00+0600",3,5)
>64680,0
write $zdt("64680,0",3,5)
>2018-02-01T00:00:00+03:00

As you see, timezone is lost. Docs for $zdth in timeopt (5) state: Specify time in the form "hh:mm:ss+/-hh:mm" (24-hour clock). The time is specified as local time. The following optional suffix may be supplied, but is ignored: a plus (+) or minus (–) suffix followed by the offset of local time from Coordinated Universal Time (UTC)

Today in docs I found this example using NULL:

 WRITE $LISTVALID($LB(NULL)),!

simplified

zzdump $LB(NULL)

and NULL can be case-insensitive:

zzdump $LB(null)

seems the same as just:

zzdump $LB()

But if null variable is defined then list would contain value from variable. Case sensitive in that situation.

Does anyone have any Idea what is this? Is NULL used anywhere besides as a list element?

I have an in-memory list of items and I want to check which items match my pattern string.

Pattern string is a comma-separated list of items and special symbols like '*' and maybe '?'.

There's something similar in $system.OBJ.Compile, it accepts patterns: "*.data.*,Sample.*" - and it would compile 'Sample' package and all 'data' packages.

For example:

set list=$lb("abc", "c", "aaa", "bbb")
set result = ..match(list, "a*,*b")
zw result
result=$lb("abc","aaa","bbb")

I have a persistent class.

I want to store one of the properties there as a stream or a string depending on a size.

99% of values would be strings (less than $$$MaxStringLength characters) so I don't want to store everything as streams.

What do you think of this approach?

What's the best architecture to implement in this situation?

There are situations where we want to provide immediate feed back to inbound Web Service that a particular business operation is not running (status <> "running"). We don't even want to queue up the message. We just want the webservice to respond with an error stating the business operation is down.

n00b questions

Hello,

I have some beginner questions as I am working through the InterSystems Cache learning path:

- Where I work, we us Cache, but we often learning about and train on MUMPS. No one really talks about or mentions MUMPS here, but my understanding is that ObjectScript is basically MUMPS plus whatever new things InterSystems put on top of it. Is that a fair assessment?
