Question Laura Cavanaugh · Nov 3, 2017

Hello; We are managing several Ensemble instances on several servers.  One server has 4 instances, and two other servers have one instance each (those are production servers).  We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

What I'd like to know is what are the best practices for managing encryption keys for separate servers. 

The options are

Question CJ H · Nov 5, 2017

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

ClassMethod testInsert()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))
  hang 15
  &sql(ROLLBACK)
}

ClassMethod testRead()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED)
  &sql(select count(*) into :ans from Test.Table)
  &sql(COMMIT)
  w !,ans
}

Question Gerry Connolly · Oct 31, 2017

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live.  Or does this even matter?

I am trying to replace one of our SQL Integration Service jobs with Ensemble and I am running into an issue executing a query against a MS SQL database using JDBC drivers.

My SQL Outbound code looks like this.

Method SelectPaceartCharges(pRequest As osuwmc.Paceart.DataStructures.SelectPaceartBillingExtract, Output pResponse As EnsLib.SQL.Snapshot) As %Status [ ReturnResultsets ]{set query = "declare @currentYear int=datepart(year,getdate()) "set query =query_" declare @secondSundayOfMar datetime = CAST('3/8/' + CAST(@currentYear as varchar) as datetime)"set query =query_"

For an introduction : look  at article https://community.intersystems.com/post/advent-code-2016-day1-no-time-t…

In this challenge, you need to find a password using instructions to move on a keypad.
Instructions can be U(p), D(own), L(eft) and R(ight).

You start at button 5 on a keypad like

1 2 3
4 5 6
7 8 9

each line of instructions lead to one digit of the password.
Full description can be found at http://adventofcode.com/2016/day/2

For example : ULL leads to '1' (a move outside the keypad can

Question Larry Pinsky · Oct 27, 2017

I have a text file that is fixed width delimited and am using a BPL to process this file, ultimately performing a transform from the text file to an HL7 message. I created a DTL, mapping from the recordmap to the HL7. In my BPL, I am performing some loops and other logic (that all is working). My issue is what to do when I perform the Transform.

I thought I could just call the transform and pass in the string as the source and a HL7 Message as the target.

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

If the above does not sound familiar to you please start at the beginning with the following:

Question Jason Ip · Sep 20, 2016

So just this morning we started to get this error from all of our SQL-client based tools that connect to our Caché SQL via ODBC: 

[%msg: <Error instantiating cached query class in Prepare(): <METHOD DOES NOT EXIST>Prepare+41^%SYS.SQLSRV *%New,%sqlcq>] (State:S1000, Native Code: 190)]

No queries work... any help? stumped over here.

doing a SQL query via Class %SQL.Statement

##class(%SQL.Statement

in Caché command line works... so that's why I think it's an ODBC issue..

I can't seem to find a SQLSRV class in the %SYS documatic

Greetings to all! Faced with such a problem, I ask for help, someone with great practical skills I think has already implemented this.The task was not to delete any objects from the database, but somehow mark this data deleted by client, because of this, I added Property Deleted As% Boolean [InitialExpression = 0];in the class.And in the redefined method %OnDelete:

ClassMethod %OnDelete(oid As %ObjectIdentity) As %Status [ Private, ServerOnly = 1 ]
{
        s person = ..%Open(oid)
        s person.Deleted = 1
        d person.%Save()

Question Nicky Zhu · Oct 24, 2017

Hi guys,

I'm trying to immigrate some of my HealthInsight dashboards and pivot tables to another HS instance.

In some pivot tables, I defined them with a set of calculated dimensions defined in the analyzer, e.g as below:

Then when I exported the cubes and pivot tables in used to my new envirmonment. When I open my pivot tables again, the calculated dimensions are missing and hence my pivot tables no longer work:

Is there any way to export those calculated dimensions so that I can used them else where?

I want to limit the length of the value of a textarea in Zen. In HTML the textarea element has a 'maxlength' attribute, but the Zen component doesn't have an equivalent property. Is there any way to add a maximum length in Zen short of creating my own custom component?

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

  • Lot's of $c(10) control characters
  • Multiple whitespaces

Here's an example of the text extracted from HTML page:

set text = " "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_" Word1"_$c(10)_" "_$c(10)_" "_$c(10)_" "_$c(10)_"

Question Alexey Maslov · Oct 17, 2017

This small function is of great need sometimes. My solution is straightforward:

dupquote(str) ; duplicate quotes in str    quit $replace(str,$char(34),$char(34,34))

I'm just curious whether other solutions exist. Is there some "standard" and/or quicker approach which I've just overlooked?
