Build Python bind

I'm testing with an application I'm writing in python.
But I noticed that the pythonbind3 library will only work on the same machine where the cache is running. Is there really such a dependency?

I'm trying to run the examples that are in the / dev / python / samples3 folder, but they only work if I set "LD_LIBRARY_PATH" with the path to the cache installation folder.

But... I have this error when LD_LIBRARY_PATH is empty:

I have java language experence. If I need parse a binary tcp packet . like following format

encoded string and send it to peer by tcp

1byte msg type + 4 byte(unsigned int) + raw byte(body)

To parse this package , Some Java code like this:

byte[] data = new byte[1024];

Bytebuf buf = new ByteBuf(data)

byte type = buf.read()

int len = buf.ReadInt()

It's well-known among Studio users that besides few predefined code fragments (for ObjectScript, Basic, MV Basic) it's possible to add user-defined code fragments. I found it rather convenient to use them as patterns that help to follow some conventions (internal standards) of writing, say, methods descriptions.

But I didn't find a way how to share these patterns, except dumb copy-pasting. Did somebody succeed with this task? Any help would be appreciated.

Hi,

I exported selected globals from a Cache 2017 database into a single 4 Gb gof file. Now I tried to import from this file via Management Portal on a different machine . Only about half of the globals was imported and my attempts to select additional globals led to nothing, no new globals have been imported. Well, obviously I am mildly curious what's going on and how can I see the corresponding error which did not appear in the Import window but I can also shrug it off and consider what should I do next.

Dear community

I'm using HealthShare on Cache 2017.2. I'm trying to find out how I can get a list of all the custom classes, routines and globals in %SYS namespace (if it's even possible).

We're about to perform an upgrade, and in the docs it mentions needing to check for anything custom in %SYS to avoid important stuff being overwritten. Some of our solutions have been developed by an external consultancy and we want to make sure that none of their code or data will be affected by the upgrade.

Hi Community,

I am looking some kind of logic or trigger some events when cache process ends.

For example, if I set some X global when i logged into terminal and when I closed the terminal or process ends by its own, global to be removed.

Thanks in advance!!!.

IRIS SQL Linked Table

Hi everyone

Anyone knows how can we add a column to an existing linked table in Cache to reflect the external SQL table?

I've tried different queries. It does not fail but does not add the column either...

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:

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

Hello,

We would need help.

We have used the following commands:

set fecha = "2021-08-18T07:44:14.180+0000"

set nuevaFecha = ##class(Ens.Util.Time).ConvertDateTime(fecha,"%Y-%m-%d%T%H:%M:%S","%d/%m/%Y")

And when we write it to the terminal:

w nuevaFecha

It outputs nothing

Could you help us?

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.

Hello everyone smiley

We are facing what seems to be a network problem while transferring HL7 messages from Ensemble/Healthshare to a distant target through TCP/IP.

Here is the version of the system in any case it could be useful: Cache for Windows (x86-64) 2017.2.1 (Build 801U) Wed Dec 6 2017 09:07:51 EST [HealthShare Modules:Core:14.02.2415 + Linkage Engine:15.03.9901]

dotnet core

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

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 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

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:

My questions are below.

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

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
