#Caché

40

  

InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

Sounds odd - but I encountered it - twice now. Cache was restarted. in that period the primary journal directory was full and it was writing to the secondary journal directory. So upon start-up, it was quite obvious that it was not going to write to the primary. Cache reported this but was able to continue with the start-up but writing to the secondary. All of a sudden it doesn't recognize the 'primary' config any more and started saying 'Alternate and primary journal directories are the same'.

Hi,

The following sql statement is working through the SMP but couldn't make it work through the code.

The table is a linked table to oracle db.

Tried to change the date property in the linked table class from %Date to %String and also tried using %SQL.Statement and %Library.ResultSet

this work through SMP:

INSERT INTO PACKAGE.SOME_TABLE_NAME

(EFFECTIVE_START_DATE,MORE,DATA,HERE)

VALUES (to_date ('2018-04-01','yyyy-mm-dd'),123,456,789)

In the code i'm using '?' in the statement for the parameters.

Hi all,

Do you know if there is a way to create a Lock that is related to an existing transaction, in the sense that if transaction is finished (commit or rollback) Lock is removed. I ask this because in the following example Lock is there until process is killed.

Example :

TSTART

Lock +^MyLock

TROLLBACK

I know, that, Caché itself is locking internally a table register when doing an OpenId with exclusive flag during the transaction life. For example :

TSTART

Cache Studio 2017.2

Hi all,

I hope this is the right forum to ask this type of question, but I'm running out of ideas.

For reasons beyond my control, we run a version of Intersystems Caché (2013.1) that is not supported by Atelier. As such, I use Caché Studio to do my development.
The issue I have is, I don't run Windows or MAC, but Linux (Ubuntu 18.04 in my case). I've successfully managed to get Studio working using Wine and pretty much everything is usable.

I have a CACHE.DAT file that is working under CACHE version 2015.1.0.429.0

I have a second machine with CACHE version 2017.2.0.741.0

When I attempt to add/use the CACHE.DAT in the new version of CACHE, it will not mount.

How do I upgrade/convert the DAT file to make it work under the new CACHE version?

Thx. Larry...

Is Cache the preferred database source for extracting data elements for use in Health Share Patient Index or is there a significant benefit in sourcing data from a warehouse, data mart, or MV? I realize that could be a loaded question with 100 other questions that may follow, however, if there is a known advantage to extracting data from a particular data storage type, the answer may highlight that point.

404 Not Found

{
"error": {
 "errors": [
  {
   "domain": "global",
   "reason": "notFound",
   "message": "Not Found"
  }
 ],
 "code": 404,
 "message": "Not Found"
 }
}

I want to do something like the above sample from a Google Storage JSON API. I have a call to Write obj.%ToJSON() followed by return ..ReportHttpStatusCode(..#HTTP404NOTFOUND) however the HTTP Status code is always 200. If I remove the Write obj.%ToJSON() statement it returns a 404 status with no body. How do I return both?

ID vs %ID in tables

What is the difference between %ID and ID in a database table? Both seem to reference the same column labelled ID.

For context, I am trying to create a viewer class for an existing persistent class.

Let us call the persistent class A, with SqlTableName = OldA.

The viewer class will be B with SqlTableName = A and ViewQuery = {select %ID, <other fields> from <some other class with the same fields as A>}

I need to write a script to answer a couple of fairly simple questions:

1) What is the current routine DB (name and location) for this namespace?

2) What is the current data DB (name and location) for this namespace?

3) Is global ^ABC mapped to a different location than the default data DB?

Can anyone point me to some system APIs that would allow me to answer these questions?

Thanks!

BPL - Foreach IF statement

As part of a BPL I am building I need to foreach over a some repeating elements and look for a certain value, if said value is present I need to forward the message to another operation.

I can't seem to get the if statement inside the foreach loop to work and I think I am doing something wrong?

The error message I am getting:

ERROR <Ens>ErrException: <UNDEFINED>zS2+2^GWH.Messages.Eobs.AKISegmentCheck.Thread1.1 *k1 -- logged as '-' number - @' Set k1=request.GetNextIndex("PIDgrpgrp("_(1)_").ORCgrp()",k1,.tSCTrans)'

Can anyone explain that error to me?

I have a simple callout library:

#define ZF_DLL
#include

#undef ERROR

int GetRandom(double* random) {
   // Py_Initialize();
   // Py_Finalize();
   *random = 1.0;
   return ZF_SUCCESS;
}

int main(int argc, char **argv)

}

ZFBEGIN

I compile this code as a shared library and it works fine with:

Hi All,

Can someone help me getting the security features & standards which InterSystmes Cache adheres to ISO 27001 & other security & privacy standards.

Also if you can tell me the algorithm used for database encryption & key strength by default.

This is required for a security audit.

Thanks in advance.

Parent/Child Vs One/Many

Hi

Just curious to know about the pros and cons of Parent/Child Vs One/Many.

We do use a bit of both.
One big reason we use Parent child is we feel if we delete one global, it gets rid of all child data too and all parent child data is stored in one global. Much easier to manage.
