Hi,

We are using CACHE 2017.2.1, I would like to retrieve data from Journal for killed global. Let say we have global name ^ EMP(123) with data and also have some child nodes and it has been killed by using cache kill command for some reason and we don't know who has executed this and when. My questions are below.

1) Can we get back the data of killed global from journal files,Is it possible or not ?

Hi Developers

Is there any way that we can pass the values to the read prompts via cache routine.

For example, we have a couple of reports/routine in our system which accepts some inputs and after taking the inputs it generates some data. Right now it has proper UI and where User enters the value and in routines we have Read statements which accepts those inputs for further processing.

Validate signature from string

Hello,

We would need to handle the following use case:

A system replies to our GET with a list of codes and a signature.

Each code has been signed with the SHA512withECDSA algorithm

We would need to:

1 Concatenate all codes in a string

2 Decode the string which is in Base 64

3 Validate the string using the signature which we get in the reply

We have read for step 2:

Base64Decode

Hi,

I'd like to compare classes in two namespaces, whether the corresponding .cls code exist in both namespaces or not, and if it does exist in both namespaces, whether the CLS code is identical. If there is such a routine out there the better, I'd like to see it. If not, I know how to get a list of classes in each namespace and I can check currClss.TimeChanged. What I cannot find is the following:

Hi:

I have an sql outbound adapter. Sometimes we have trouble connecting to the database.

The timeout in develpment is set to 15 seconds in live it is 150 seconds as it is an always connected Buisness operation.

I thought adding E=S or/and X=S would suspend the message. Why does it not?

Is the only way around then adding something to the buisness operation itself/ creating a customised SQL buisness operation rather than EnsLib.SQL.OutboundAdapter?

Thanks

Mark

And when we write it to the terminal:

It outputs nothing

Could you help us?

Hi,

Can anyone please explain me how to remove trailing squares from the text field (String). Trailing squares is a white space ?

I tried different things like Ltrim, Trim from sql query side and also from object scripting side something below.

If Address1 set Address1 = $ZSTRIP(Address1,"<>P,<>C,<>W")
If Address1 set Address1 = $ZSTRIP(Address1,"$C(9), $C(32), $C(160)")
If Address1 set Address1 = $ZSTRIP(Address1,"*W,*C")

Nothing works for me

Can anyone please help me to solve this

Thanks

Hi,

I am brand new to Cache and have been tasked with extracting data from the dB. I see that there are a bunch of tools that can be used to extract via SQL Server statements. DataGrip and DBeaver to name 2. I've gone through some documentation and it doesn't look as if SSMS can connect directly. Is there a preferred extraction tool that anyone can recommend. Does the Cache dB have anything built in where I can access the data while seeing a visual of the tables/schema?

Thanks for any advice,

Hello Intersystems-Community,

I build an API and there I use $order to get the Data from my Globals.
When I first time use that API it's get an error (504 Gateway-Timout > 60 Sec.).

After 2 reloads it works with a loading time of 2 Sec.! Sounds for me like the $order is cached and it works faster. Is it true $order will be cached?

When it works, I only get the error at the next day. So it's very hard to reproduce that error. Is it possible to delete the cache for $order?

Example:

Is there any way to change the sql Shell interface to output a <TAB> between the fields instead of outputting one or more spaces between columns

I needed to run an sql ( that took a while to run) and then cut and paste the generated output into excel, trouble was the paste into excel was not very good for columns when there's spaces used between the columns

Explicit FTPS in Cache

We use the %Net.FtpSession class to perform FTPS file transfers. This has worked fine with Implcit FTPS servers but crashes when trying to connect to an Explicit FTPS server. Explicit FTPS has a slightly diffferent negotiation in the intitial connection and different ports.

Has anyone gotten Explicit FTPS working with the Cache classes?

Abstract Classes and Methods

I have been looking into using abstract classes and methods. In other languages, if a superclass is defined as abstract, subclasses inheriting from the superclass will not compile until all abstract methods have been implemented in the subclass.
I have created the following classes to try this in Cache:
Class User.Music.AbstractClass [ Abstract ]

Until this week, my customer had Ensemble writing HL7 messages to my TCP listener, working fine on ageing physical servers (Windows Server 2003, Caché 2009). They had four app servers (app1, app2, app3 and app4) with an overarching DNS simply called "app". Ensemble was connecting to "app:port", and it somehow found whichever of the four app servers my background listener was running on, and the interface worked fine for 10+ years.

Server-less incoming Web-hooks

Hi,

Recently I have encountered a new issue, more and more 3rd party applications move to the cloud.

Web-hooks incoming from their sites can no longer be identified using a known and fixed IP address, so our customer's security department blocks them.

In past similar cases we use to grant access in the customer's Fire-Wall to the specified IP address - this is no longer applicable.

Has anyone else encountered this problem ? do you have any ideas ?

Thanks
