InterSystems Caché is a multi-model DBMS and application server. See more details here.

We are retiring a hosted application for an electronic health care records (EHR) system which stored the data on Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.2.2 (Build 867_4_20245) Thu Oct 8 2020 16:58:40 EDT. The hosting company is providing me with a single CBK file. I need to install a database system to restore the database and provide occasional SQL access for reports when necessary. I'll need to maintain access to the data for an approximately 10 year retention period. Not sure how to approach restoring this old of a database and eventually upgrading it to a newer re

Hi,

We have a global with 65 million entries. All we are doing is just iterating through each entry to find out the total no of entries. It is currently taking 110 minutes. Is this something normal? What can we do to speed up this process? Below is the program for just iterating each entry in the global.

s sub=" ,count=0
f{
s sub=$o(^YYY(sub)) q:sub=""
s count= count +1
}
w!, "Total Count:"_ count

We have a service account that is running queries to pull some data. It has read only access to the tables, but, unfortunately, the tool is starting a transaction before it reads the database. The query takes more than 20 minutes (21 - 23 minutes), so we're getting the console message that the transaction is open longer than 20 mins. Is there a way to prevent a user/service account from being able to start a transaction since it only has read access to all of the tables in the database?

I need to develop a tool to help to get what data is being consumed by a certain process, in order to get all data used to build an automated test scenario.

For example, some user process will pull data from ^GLOBAL(1)="dataString", ^GLOBAL(2)="dataString2", ^GLOBAL1(1)="data1String", ^GLOBAL2(4)="data2String4". Amidst all other data on these Globals, I will ignore everything that was not used in the user process, and get the specific keys used on it.

Hide or make routines binary?

Sorry, somewhat of novice here, but how is a mac or a routine created into a binary or is there a way to hide your routines so that no other user can edit them? Like remove source code and have an executable?

I would like to do this MAC and CSP pages

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

After installing IRIS 2023.1 on a live copy of our production machine our REST Service now consumes a CSP Session with every request. The request is handled as expected, but uses one of the 5 CSP Session per license. So after 25 requests, the license is used up. The Grace time always shows 0 and the session stay for very long. (Maybe the 900 Seconds timeout).
On Caché 2018, we had the same settings for the Webapp and there, only a single Session was set for all requests. The Caché request didn't use any cookies.

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Hi,

An exception occurs randomly.
I expect the value of ^TEST to be 20, but it's not.
Did i miss something like closing, flush the stream or locking the global?

Cache Studio for Windows 11

Has anyone tried loading Cache 2017 on Windows 11?

I'm working with my corporate IT department to get a version published that will work on Windows 11 desktops but I have to prove that it can be loaded before they will give me the rights to install it.

It looks like Cache 2018 is supported but we're still supporting a bunch of 2017 installations until we can begin the move to IRIS.

Meanwhile the new laptops are all being issued with Windows 11 and the installers are all blocked by corporate.

Enabling telnet

Can %Service_telnet be enabled programmatically? I have the need to enable this feature so that I can automate a script I have for Cache, but unless the telnet service is on, the session cant connect.

This is for the veteran programmers out there (you know who you are; you started programming before date 60000).

I'm in the middle of updates for our system, and I've come across many $ZU() calls. Most of them are documented in the "Replacement List", but two are missing: $ZUtil(0) and $ZUtil(1).

I honestly don't remember what these are for (and I'm pretty sure I used them in code in a previous century), so if someone can tell me, great. If you can provide a link to a reference, better!

As always, I appreciate your help.

There is test folder inside my sftp server. I executed the below lines of code

s ssh = ##class(%Net.SSH.Session).%New()

d ssh.Connect("host")

d ssh.AuthenticateWithUsername(username,password)

d ssh.OpenSFTP(.sftp)

s remote="\test\sample1.txt"

s local="c:\orders\sample1.txt"

s status=sftp.Put(local,remote)

I get the below error

"MSSH Error [8010102B]: Unable to send FXP_OPEN* [8010102b] at SFTP.cpp:539,0Put,IM%e^zPut+2^%Net.SSH.SFTP.1^1e^^^0"

in Management Portal on Freespace screen there are links to compact and truncate a database.

Can these tasks be done programmatically? I have looked through documentation and dont see anything but I hope I just missed it.

Thanks,

I got a problem to resolve, to sum it up I need to extract a function body from a JS file with cos.
I already got the JS code in a string and the function name but I'm kinda stuck as to how to get my function body, I already tried a few things (regEx, counter bracket) but there are comment and strings that block them from functioning. Is there a javascript parser or a good way to do it except by creating a javascript parser?

Storage %SYSTEM.Event

Hello, How are you doing?

I'm currently developing a proyect in wich I want to use %SYSTEM.Event to process queues. I realized that if a queue has events pending to be sent to the listeners, when I restart the cube the queue with all its events are deleted.

Is there a way to store the queue with their messages in a Global?

I've checked the documentation but I can't find any option for this prupose.

Reviewing a client console log, I am finding the message:

Terminal disconnect: The specified network name is no longer available.

This message is repeated in the log dozens of times per day over the last month. The client has not raised a concern and our monitoring has not detected any issues with client ops. The client is not aware of any recent changes with their apps. I am not familiar with this message and whether this message is benign or whether there is any action required,

I'm working for an organisation that is running a very old version of InterSystems Cache (5.016) which runs on AIX . The last two times we have re-booted Cache, we have encountered rollbacks. I've been asked two questions. During the rollback it was "How long is it going to take?" and after the system returned, it was "So what caused it?". My answer to both was "I don't know".
