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

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?

Exception

Hi all,
Does anyone have experience with obtaining logs from Caché databases and parsing them now? Please leave me a message.

I ask because my project involves some hospitals that used Caché when creating databases over 10 years ago. Currently, we cannot replace the database, but we need to check and parse the database logs from the Caché.

Thanks.

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.

Hello everybody. I have a problem a little bit strange. The thing is that there is a Task on Cache that by default is executed everyday at 4:00:00 that, with my settings, will delete all the Audit logs with more than 70 days of existence. The problem is that everyday this task is executed without an error message (status "Success" after the task is finished) but no data is cleaned, the same if I executed this particular task on the "Task Schedule" screen. I'll put here a screenshot of the message after executing the task on the "Task Schedule":

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.

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 have some databases in my cache instance that were created from an online backup file (.cbk). I would like to see the information for these databases in the Databases and SQL sections of Management Portal, but they only appear in the Classes section. I can navigate to the files in my cache instance terminal and see the CACHE.DAT files, and a check in the terminal shows that they are mounted.

This is what I see in the terminal for each database when I check to see if the databases are mounted:

%SYS>set db="/path/for/mydatabase"

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.

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

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?

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.

I'm having trouble adjusting the protocol used for any CSP Requests. Currently all request to the system are sent over HTTP 1.1

When loading 40+ images on a page, the browser starts stalling request. According to google HTTP 1.1 only allows 6 parallel TCP Connections before suspending the remaining.

I have looked through the Web Gateway Settings, %Net.HttpRequest.HTTPVersion and SSL Configuration but haven't found anything.

Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.
