#Caché

I use %SQL.Statement. The original column names are not contained in the metadata.

Sample query:

SELECT
 column1->name as name,
 column2 age
FROM sample.table

How to get:

•  column1->name
•  column2 

Hi

I've got a Service that get ACK Messages originated by another system. 

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.

Please excuse my ignorance. I am trying to identify what areas would be best to review in the System Dashboard (for Cache 2010.2) for performance issues with the database. It seems to be running slower than usual, but I am trying to find out the best way to go about identifying what the issue is.

The following are captures from the System Dashboard.

As always, thanks a lot for your help.

Hi,

Hi all, I'm running into an issue with the installation, it seems like almost everything is working alright but upon trying to actual access the Management Portal, the site cannot be reached. I've noticed that the terminal indicates that Sign-on is inhibited. 

To add some context, I've installed Cache following the Unix instructions for MacOS (El Capitan). I can share the log or any other info that may be helpful. Here is some of the terminal output from the installation if it would prove at all helpful.

DC readers running Caché etc on Windows, configuring the Telnet service to use SSL/TLS, and using the Caché Telnet client (CTerm.exe) to make the Telnet connections may like to know that there's a fault in 2017.1 and 2017.1.1 which prevents CTerm.exe from establishing the secure connection.

Workaround is to use a pre-2017.1 kit to install on your client machines (e.g. 2016.2.2), or to fetch the bin\cconnect.dll from an earlier version (I used 2016.2.2) and use it as a replacement for the 2017.1 / 2017.1.1 copy.

Hello -- Is there a way to load a JSON from a file.

I have a "JSON" file which has a sting 1035164 long with the following format: 

[
    {
        "id": "12345",
        "title": "John Smith",
        "image_uri": "https://<some URL>",
        "image_timestamp": "1496781334",
        "image_url":"https://<some URL>",
        "is_restricted_under_18_only": false,
        "is_restricted_adult_only": false
    },
.

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.

Example:

(for example globals: ^data1, ^data2, ^data3 are critical area)

Should I use somehow function $LOCK() or there is another way how this can be done?

An installation or upgrade of Caché, Ensemble, or HealthShare on Windows could fail with the titled error if a newer version of the Microsoft Visual C++ Redistributable 2013 (x86) or (x64) is installed instead of version 12.0.30501.

If you encounter this error during an installation, you can get around it by uninstalling those versions of the redistributables in the Control Panel, then manually installing both x86 and x64 older versions directly from this link This problem has been corrected in maintenance kits 2016.1.4 and 2016.2.2 and all released 2017 versions by devchange ALE2949.

How to we count no.of nodes in global.

There is method:

$System.OBJ.New( ClassName As  %String = "" )

If class with name ClassName exists - everything is OK.

But, when class does not exist, there is error - <CLASS DOES NOT EXIST>

How can I check before calling $System.OBJ.New() if class witn name ClassName exists?

Greetings!

I'm new to Zen reports and I'm wondering if what I'm trying to do is possible.  I have a classmethod  that accepts three parameters to generate an xml file from a global.    I've set up my Report Definition to call the ClassMethod that generates the .xml file; however, I'm trying to figure out how to pass the parameters to that ClassMethod from the Report Definition.  The example in the documentation shows parameter passing using SQL (which I'm not using), so I'm curious if this will work.  

Hi Guys,

We need to print html reports, in the server side, to a specific printer that is installed on the Cache Server , and using the Internet explorer that is installed on the Cache Server to do that .

Hi!

Hi,

I am new to Cache' MV but have extensive experience with other Pick flavors especially Unidata. 

I need to determine the impact of adding several indexes to a large file with over 51,000,000 records. 

On other systems, I could use FILE.STAT, ANALYZE.FILE and shell to the OS to determine how large the index file was. 

None of those seem to be available in Cache' MV. Shelling to the OS just tells me the size of CACHE.DAT.

What is the best way to determine what the disk impact would be if I added an index (CREATE-INDEX) to a file?

TIA,

Steve

Hello,

I have a DB server (ser-app-db) where cache is installed as server.

I have a Web server (ser-app-w) where cache is installed as web server and configured as CSP gateway.

I followed the configuration guide (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KE…) and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/csp/samples/docserver/request(GET): work and show the request

http://ser-app-w/csp/samples/docserver/request(GET): return a 404.

Hi

1. Is it possible do define an index like that :

create index UIX on MyTable (Column1) where Column1 is not null

2. What happens if we add an index on a property that is NOT required, meanning that not all records will be indexed because we do not allow null subscripts ?

Good day,

I need to find out if it is possible somehow to receive actual linux TIMESTAMP for example with $NOW() or other functions.
I was trying to recalculate it with $NOW() function, but without success. I would like to simulate Redis TIME command in COS.

My tryings:

USER > set time = $NOW()

USER > w (($PIECE(time,",",1)*86399) + $PIECE(time,",",2))
5573319043.403186

But in Redis it is:

> time
​1) 1502471158

On web page: http://try.redis.io/
type "time" + enter. And it will results as short documentation says: https://redis.io/commands/time

And this behavior I would like to implement in COS.

I have a list of %Library.ArrayOfObjects . Each of list elements has some properties. I have to sort list by one of its objects properties. Is there a predefined method to doing that? (quicksort maybe?)

I have a tablePane. TablePane can have one, or two, or three parameters. It depends on some conditions.

At first I add all three parameters to tablePane.

set p1 = ##class(%ZEN.Auxiliary.parameter).%New()
set p1 .id = ..id1
do table.parameters.Insert(p1 )
do %page.%AddComponent(p1 )

set p2 = ##class(%ZEN.Auxiliary.parameter).%New()
set p2 .id = ..id2
do table.parameters.Insert(p2 )
do %page.%AddComponent(p2 )

set p3 = ##class(%ZEN.Auxiliary.parameter).%New()
set p3 .id = ..id3
do table.parameters.Insert(p3 )
do %page.%AddComponent(p3 )

Then through javascript I set parameters values and query

I understand this is a rather broad topic (and at times involves religious sentiments) yet I would like to look at it from the Caché perspective:

• Do you use an issue tracking / collaboration system? If so which one. Any you would recommend or immediately dismiss based on personal experience?
• How do you keep track of large code bases? Thousdands of folders named backup1, backups2, ..., SVN, git?
• Do you have a development server to which you commit and test features there, or do you rather run a local copy of caché and implement features locally first, then push to the

Hi, I am trying to understand the transformational methods.

• LogicalToDisplay()
• LogicalToOdbc()
• OdbcToLogical()
• DisplayToDisplay()

I have created a small class with the only property of List as %List, see below.

Class LastName.Demo2 Extends %Persistent
{
Property List As %List;

}
Then I entered the following commands in the Terminal

Set Oref=##class(LastName.Demo2).%New()

FOR I=1:1:5 S $LI(List,I)="Value="_I

Set Oref.List=List

WRITE Oref.ListLogicalToDisplay(Oref.List)

^

<METHOD DOES NOT EXIST> *ListLogicalToDisplay,LastName.Demo2

zw Oref

Oref=<OBJECT REFERENCE>[2@LastName.

The data type %Char or %Library.Char

The description says it is a fixed length character field.

How do I set the fixed length?

Or by just setting %Char to something, does that automatically define its length?

Are the parameters MINLEN, MAXLEN involved? Or are these the way I set the fixed length?

Any help with this?

In a previous exercise, I was able to show the power of Caché.
A medium-designed set of interdependent tables with some GB of data.
URLs cross reference over some million pages resulting in ~3 billion records

Competition was between

• Caché
• PostgreSQL
• MySQL

Criteria were Speed + Storage consumption
I composed  a customized loader fed over a "raw" TCP connection
Mapping the "objects" into the final table by directly writing to Global Storage.

Hi,

I use cache 5.0 and access cache through OpenVMS.

The disk-space under a particular namespace has grown up in size due to cache.dat. How to recreate cache.dat to bring up more space back on disk?

Hi Everybody

Question , I need to define a user that will be limited to only to one namespace.

I defined the start up namespace in the user's definition , but it doesn't limit the user.

Any advice would be appreciated.

Thank you Simcha

Hi, folks!

There is an interesting discussion in the neighboring topic which raises a question for me: is there any reason to have %Status as a return value for COS method?

Hello All,

While extracting the huge amount of data in the cache through the Zen page, file extraction timing is greater than session time out. How to increase the session timing in Zen/CSP gateway or If any other solution would be appreciated.  Please advise.

Major difference between GOTO and do command?
