Hi we are migrating to Linux from OpenVMS. which includes a new server and SAN. after reading a prior post about the differences with ESX and a VSAN I would think that the a SAN with Virtual disks all SSD type would be similar. which after reading it makes me think that using thick provisioning is the way to go. the 3rd party vendor is arguing this point with me. is it the same premise? is non-dedupe the way to go with thick provisioning. we are currently on 2015.2 of Cache with the plans to go to 2018 until the app vendor is able to certify their product on the latest versin.

New to Python. Attempting to use pypyodbc to select data from a table in one Cache database, and inserting into a similarly configured table in another. Process works fine except for tables containing Date types. NULL values in date columns are handled without issue, but when data is present, insert fails with:

An error occurred: argument 7: TypeError: 'NoneType' object cannot be interpreted as an integer.

Hi,

I have a archive backup of a Cache database. I was able to restore the database but having trouble navigating through the globals, classes, namespaces .??? I am not a Cache user and/or developer so I am a bit lost. I am used to relational database such Microsoft SQL but not Cache which to my understand is a different breed of database. If you are looking for some extra money to help me extract some of the data I need i would be greatly appreciated.

I have installed three plugins on VS Code: Intersystems Language Server: v2.3.6, Intersystems ObjectScript: v2.10.5, and Intersystems Server Manager: v3.6.2. I connected to the Caché database and connected a workspace to the InterSystems server. Then I edited the code locally on my client machine.

Hi everyone,
I am trying to create a listen server in Cache 2016 that can capture data from a specific port. Can someone guide me on how to set this up, including handling incoming connections and reading data from the port? Any advice or example code would be much appreciated!

Thanks in advance!

Hello,

I'm trying to add another segment to an HL7 MDM message. More specifically OBXgrp(1).OBX. The addition itself works,. When I look at the message in the trace, the segment with the content can be seen. However, it is not displayed as an OBX segment.

Build Map Status = 'ERROR <EnsEDI>ErrMapRequired: Missing required OBXgrp(1) element at segment 6'
'ERROR <EnsEDI>ErrMapSegUnrecog: Unrecognized Segment 6:'' found after segment 5 (TXA)'

I am attempting to follow the tutorial at Publishing Web Services Using Caché | Caché Web Services QuickStart Tutorial | Caché & Ensemble 2018.1.4 – 2018.1.11 to build a toy SOAP web-service using Cache but am running into what I suspect are permissions issues, or perhaps setting up the "plumbing" to get an incoming request to call the web-service methods.

Ok, I am attempting to clarify the required use of the RESIZE command, when you have a UNIVERSE or a UNIDATA DB attached to Cache. Traditional UNIVERSE / UNIDATA databases 'require' that hashed files be re-sized according to historic use, to prevent file overflow (aka. performance issues). It is not clear if that requirement is fully eliminated by attaching one of these databases to Cache. It is clear that, if you do not allocate 'enough' space on Cache for the database 'as a whole', that is a problem.

SYSTEM OBJ Export

I have a DOS batch file that calls *.scr script to back up an existing routine and upload the newly updated one.

I have a backup folder setup in C:\Users\[username]\Backup\ on each server, some with more recent versions of cache. The *.scr script calls on the command: $SYSTEM.OBJ.Export(routine,path) .

Generate JWT token in Cache 2018

Hi,

I try to generate JWT tokens in Cache (not in IRIS).

In IRIS I managed to generate tokens using ##class(%OAuth2.JWKS).AddOct("HS256",secret,.jwks).

But In Cache there is no such routine.

Could you provide me a place to find an example how to use JWT, please ? I am interested to generate a token in Cache, send it to javascript client, and read a token provided by the client and check it is valid.

Kind regards,

Alin Soare.

Hello,
In short, I am trying to get the Content-Length of my response,

We have a CSP application, when we get a new request we begin to process it, throughout the app we WRITE to the response in different places,
now when the response is about to be sent back to the client - we would like to know its Content-Length (in the RESPONSE HEADERS).
So it comes down to two questions:
1. How can we access the Content-Length of our response?

Hello, we are currently using the Cache Database released in January 2018.

There are no specific classes or SQL mappings in the namespaces where data is stored.

Only a few routines(.mac) and stored data are in the global area.

In this case, when accessing the Cache DB through Java, is it essential to write SQL mappings or wrapper classes? The reason I ask is that our team doesn't have advanced developers who specialize in Cache.

Alternatively, is it possible to directly call pre-existing routines from Java?
