Hello Community,

we want to use a specific index on our sql-class.

The index we want to use is called "iFilter".
Currently we use the following technique of ignoring all other indices because the automatically chosen index is always too slow.

I am trying to get a list of databases using the DatabaseByServer method but I am only getting an empty string. I have not found any useful examples of the proper usage of this class/method.

I have tried 2 formats. First

set dbList=""

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList)

I also tried:

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList,"/cachesys/")

In each case dbList is empty string. I can not figure out what I am missing.

Hello everyone,

I am new to cache. I want to know is there any direct command to know how to find maximum number of subscripts in global A through direct command.

I mean the answer is 9 but how to check it using a direct command on terminal.

Thanks in advance!!

^A(1)="A"

^A(1,2)="B"

^A(2,1)="CVB"

^A(3,2,7)="'DFGH"

^A(4,1,8,9)="ASDASD"

^A(5,1,2,4,5,6,7,8,9)="ASDASDASD"

Hello everyone

I am new to cache. In an interview i was asked how to optimize a sql query.

I just said I will create index on conditions which are present in where clause. But as per interviewer I should check How query plan is getting executed. This will help in optimizing Sql queries.

I want to know what will be the answer for how to optimize SQL query in cache.

Thanks in advance!!

I wanted to write it as a comment to article of @Evgeny Shvarov . But it happens to be so long, so, decided to post it separately.

I would like to add a bit of clarification about how docker uses disk space and how to clean it. I use macOS, so, everything below, is mostly for macOS, but docker commands suit any platform.

Could you help me please. I am a VistA Application Administrator for the State of Tennessee and I have been using your web site: https://www.bmirwin.com/vnode/dictionary/index.php to write reports for the Health Departments in my state and I see it was shut down on 9/1/21.

I have a client running cache on an AIX platform. I put together a objectscript to allow for the viewing the processes running against the database using a select from SYS.Process. One of the values I want in the view of the processes information is Jobtype but I want to convert it from the numeric value to a string value. In the Intersystems documentation there is a reference to an include file $syPidTab.inc that should include macros that make this translation. I have not been able to track down this include file.

In Caché, it's possible to iterate a local array using $QUERY() :

set a("foo") = 50
set a("bar") = 30

set key = "a"
for
{
     set key = $QUERY(@key)
     quit:key="" 
     write key_" = "_@key
}

This code works perfectly, unless it's called in a job (eg: a routine called by the JOB command).

Hi

We have an application that is logged using AWS SSO.
We are passing username and password from the AWS SSO to our application for validating the user.
But what we need is, we need to login to application without using the password.
Is there any possible way available for this?

Thanks,

After linking in Oracle Table with Field Column's Data Types of NUMBER, my updates into these table fields are resulting in data that is being rounded to 2 decimal places. I insert a record with 1234.1234 and 1234.12 is stored.

It appears Cache xDBC might be manipulating my values prior to sending to Oracle. Is there a setting or system parameter that is controlling this? If so, is there a way to relax this from occurring so the values I send are being stored in Oracle with the same values?

Hello,

We need to upgrade our cache instance from 2016.2 to the latest version.

I find the documentation about the "Upgrade Path" but I cant find where I can get the files to upgrade in the documentation.

Also I cant find how to make this upgrade, they talk about strategies but dont talk how to perform the task to upgrade.

Is there any documentation of how to make and upgrade and where I can get the files?

Hi developers!

Do you know a CRM that is built with InterSystems IRIS or Caché or Ensemble on a backend?
