I'm using $ZF(-1) in a class method which will be invoked from a csp page.

What determines the environment of the spawned process?  If I use $ZF(-1,"echo hello world > output.txt"), the resulting file is owned by cacheusr:cacheusr.  However, when I use $ZF(-1,"printenv > output.txt"), the environment is from my personal unix account, no matter which Cache username I'm logged in under when running the web application.

objects in javascript :

var oM = new Object;

var mMode=["down","up","click"] ;
var key,val ;
    for (key in mMode)

       val = mMode[key] ;
        oM[val]={} ;
        oM[val].id   ="" ;
        oM[val].type ="" ;



so I can access the .type directly as :




what is the syntax in CACHE or IRIS, to achieve such approach via class/key/property...?

acctually: class/object/key/property anlaogue to ^GLOBAL(key,"property")=val

$preprocess failure

There is an undocumented command, $preprocess, that can be called as below. In this case it takes the class name and converts its code into a text array. That includes comments as well. Two questions about it if you know:

Hello everyone,

I don't want to believe that Intersystems didn't add a method/process/rule to sort alphabetically a list of names (in array, $ LB or whatever)

I haven't found any documentation about this. I've even tried comparing two strings but have not found a solution.

My cry for help is...

Does exists any command to compare two strings and check if one of them is lower or upper according to aphabet?

Please, give me a light in this dark

Best regards.

I need to show the absence of data, so I have to join the list of predefined values with a result of a select statement.
However, it seems like Table Value Constructors in JOIN are either not supported, or I do not understand the syntax.
Basically, I am going for something like this:

Select v.valueId, m.name 
 From (values (1), (2), (3), (4), (5)) v(valueId)
     left Join otherTable m
        on m.id = v.valueId

Is it supported in Cache SQL or not?

Cache code conversion tool


I have a requirement to convert few screens having character based interface built in Cache to a web based interface in Java while still keeping Cache as the backend which means database will remain the same. Wanted to know if we have any tool in the market which can help doing that keeping in consideration that these screens in cache are using mumps code. 

If we don't have any tool, would appreciate if someone shares their experience in the manual conversion as well.

I have a quick question regarding TSTART, however not certain if there is an answer.

If I am inside the transaction and I loose connection - I always assumed that transaction would TROLLBACK, however it does not.

Is there anything special I need to set up with my TSTART, in order for this transaction to safely rollback?


As example: Let's say I am inside the TSTART and setting up / altering some data and my VPN connection got disconnected.  I kind of expect all the data to be rolled back.  

Thank you,

Hi everyone,

I'm currently developing a TCP inbound Service to read some XML sent from a TCP Operation that uses EnsLib.TCP.CountedOutboundAdapter.

1) I have tried EnsLib.TCP.Inbound adapter but that gives this error:

ERROR <Ens>ErrException: <METHOD DOES NOT EXIST>zinitConfig+7 ^Ens.Host.1 *%New,EnsLib.TCP.InboundAdapter -- logged as '-'
number - @'
Set ..Adapter = $classmethod(..#ADAPTER,"%New")'

Due to this, the adapter is unable to start listening for incoming connections.

I checked out a Git-Branch and want to Import all Objectscript-Objects to my localhost.

While using Import without Compilation I receive a lot of errors.

Is there a setting, that I have to key in?

Log (Journal) shipping

I am new to Cache, we are trying to move a 4 TB database over the internet, but this will be take too long to copy the single backup file. In Oracle and MS-SQL Server there is an option of doing log shipping. Is there such an option in Cache?

I want to copy the initial backup file one weekend, then keep sending the Journals (logs) the new location.

Thank you,

Hello everyone,

First, thanks in advance for your help :-)

I noticed that a query called directly in a method of a class of a business operation does not return the same result as if I apply the same query in the same Caché database from Squirrel !!! 

I don't understand why ??? 

Here is the query :

Hi Team,

I have a requirement to delete the Ensemble interfaces , as per User request. I would like to write a routine for that and once I execute, it should remove the interface components through code.
Could you please provide code samples for the following actions ?

  • Deleting an individual rule from a rule class
  • Deleting a class from Ensemble
  • Deleting a Host (Service/Operation/Process) from the Production.

Appreciate the help.

Let's say I have a persistent class Sales.
I need to create a report that shows the amount of sales for each branch.
By simply using the class Sales for the source of the cube, I can show what I want with one little exception - the branches that did not have any sales are not shown.
Is there a way around that that does not involve creating a whole new table just for this cube or using a Data connector (they have horrible documentation and I am unable to figure out how to use them properly)?

I'm trying to add a DR async member to a mirror but when I add this member I get this messages in the mirror monitor (on the DR member):

The message im talking about is the "missing Mirrored Databases report".

The only step I did was the " System Administration -> Configuration -> Mirror Settings -> Join as Async" an fill the blanks. Maybe Im skipping a step?

The boss (reasonable intelligent ;-) wants to connect to the cache database through Excel, but unless I explain what he's looking for (field names DB names etc) then I can see him continually coming back for "what's the link here and how do I get the delivery company name etc etc"


is there a SAFE way I can give him access to our database using an intelligent visual user interface.

I had thought about the SQL Query Builder within the management portal, but the thought of giving him access to all of the other functionality of the management portal.

We are seeing more and more customers being lured with latest infrastructure technologies, particularly Composable Infrastructure. Coming with all sorts of data center consolidations and costs savings.

Question is: are there any concerns for HealthShare/TrakCare being run on these platforms or things to look out for? Anyone out there, already on these platforms?


To be more specific this is HPe Synergy with 480 Compute blades booting as bare metal.
