When there's a performance issue, whether for all users on the system or a single process, the shortest path to understanding the root cause is usually to understand what the processes in question are spending their time doing. Are they mostly using CPU to dutifully march through their algorithm (for better or worse); or are they mostly reading database blocks from disk; or mostly waiting for something else, like LOCKs, ECP or database block collisions?

I am trying get the Unix time stamp in milliseconds

set epochSecond= $ZDATETIME($ZTIMESTAMP,-2)*1000

but the result is not accurate as $ZDATETIME ignoring /truncating the fraction of the seconds and the milliseconds calculation is not accurate with fraction seconds

for example

set epochSecond= $ZDATETIME($ZTIMESTAMP,-2)

1675830682

when its converts to the milliseconds

it became 1675830682000. not the accurate fractional seconds.

My target system looking for the milliseconds time stamp to authenticate.

IRISTEMP - IRIS.DAT took up all the available disk space of almost 2 TB that leads to Production instance down.

After RCA the suspected cause was some SQL query but not confirmed as query result was received within a minute.

Currently we are monitoring the IRIS.DAT and it is continuously increasing and currently we set the MAX size for this DB, but not sure what will happen once it hit the MAX SIZE ?

Any clue why the IRISTEMP DB is not flushing the data from IRIS.DAT as i believe it is being mostly used for system processes and is in increasing trend at ~ 1GB/day?

HTTP request with open stream

Hi Guys,

This link (https://github.com/CassiaNetworks/CassiaSDKGuide/blob/master/node_exampl...) uses Javascript request to open a a steam and collect data in an array (screenshot below) and I'm trying to replicate this with Cache script with HTTP request which is connecting Ok but don't know how can I collect data because the code is hanging at Set tSc=Httprequest.Get(HttpURL) and cannot execute S BLEConnect=Httprequest.HttpResponse.StatusLine or any line after it.

Hi Guys,

I'm using the below to export a query result to excel file and the only file type is .csv (100) but the resulting has two problems,

first the row header is including the field type and second the resulting file is a tab delimited so columns aren't properly separated (see attached below)

set st = ##class(%SQL.Statement).%New(2,"Sample")
set sql = "select ID, name from MyClass"
do st.%Prepare(.sql)
set type="csv"
set rs = st.%Execute()
do rs.%DisplayFormatted(type,"C:\Temp\report")

Introduction

Despite the fact that InterSystems has long recommended using external backup tools, many users have opted to use the internal Online Backup facility, which is included in all distributions of InterSystems products (IRIS Data Platform, Caché, etc.). The reasons why are quite obvious:

Well my last post got cut off for some reason. I am trying the new beta and wondering about the following functionality from Studio that I don't find in Atelier:

F12 = Open the routine and jump to the tag of the current call the cursor is on in a routine

F2 / <Ctrl> F2 = jumping to a bookmark / toggling a bookmark

<Ctrl> G = Jump to a tag in the code

When might these things be in Atelier? I use them a lot in Studio and the absence of these really slows me down.

Atelier and Inspector

Hi,

Cache Studio's inspector window can show me a Cache class's properties,methods parameters, XDATA blocks, Triggers, Foreign Keys, Queries and more, in a table in the Inspector window. Additionally, for properties, where the property accepts parameters, these parameters are listed together with possible value choices.

Hello,

I need to run some clean up routine in the background so loss of my terminal session won't stop the process.

I found the JOB command in the documentation.
JOB | ObjectScript Reference | InterSystems IRIS Data Platform 2022.1

When I try it, it doesn't seem to be doing much. I also expected this to become visible in the Background Tasks but that doesn't happen either.

Probably I am missing something.
