Forgive my lack of understanding, but I am working on a vendor created Cache database and the indexes specified in the classes for ODBC connections are not working. A few of them are created, but of the 50+ classes we have, only a handful of them are created when the class is compiled, yet no errors occur.
I have classes A and B, B derived from A, A has method Abc.
From INT of class B I see that compiler copies implementation of Abc to class B, so that Abc exists both in A and B.
As result, when B invokes Abs, B.Abs() is executed instead of A.Abs(). In result debuger is not able to step into Abs and breakpoints in A.Abs never hit.
Why this happens and how can I avoid this?
Update:
OK, now I know the reason: compiler makes the copy if Abc has this line:
I need some advice about JSON conversions and the outputs. I am being sent a JSON response from an API call and I am struggling to produce an output that I can use from it.
I have used the %FromJSON() method call to take the JSON stream source (pData) and convert it to a Dynamic object (object) but I am a little unsure as to how I can read the dynamic object and use it to extract the values from this and set the values as a property in another class.
When you export the Caché ObjectScript code to VCS (Git, SVN, Perforce, etc) do you export the Storage schema for persistent classes? If so, what are the Pro/Contra?
I'm looking at adding multilingual support to a couple of open source projects I'm working on. The solutions are already developed in CSP so I am not looking for alternative approaches.
I'm wondering what would be the best approach for CSP and separate JavaScript files.
Initially I was wondering if I should bake the default system language text at compile time, or provide the end user with a language selection option at run time.
Last weekend we held the Final of InterSystems Contest on Caché, DeepSee and iKnow under the aegis of IT Planet Student Championship in Ekaterinburg. BTW, this year we had more than 1,400 participants in InterSystems Contest.
I am trying to create a method to count the number of entries in a global, including all subscripts. I am having a bit of trouble getting the code to make it to the second subscript. When I get to the position where my key is "Canada" and I add a comma and empty quotes to it, it returns USA as the new key when I do the order function. Is the $Order or the global not able to use a single string to represent multiple subscripts?
Hello, I'm currently working on a custom version control implementation. I'd like to show differences between a copy of a previously saved routine as a merge of the ^ROUTINE Global and the current version of that same routine.
I've found legacy Documentation for %RCMP which does the trick in the terminal but I'd like a similar result stored inside a variable. I also want to show differences, not only see if they are the same or not.
The management portal has that exact feature, so maybe someone can direct me to the function that is being used there.
I am wondering if there is a way I can change the GUID of an instance. The use case is that I am restoring from a backup on an alternate host and start the instance there. However, the restored instance ends up with same GUID as that of source. Is there a way I can tell this newly restored instance to use a different GUID?
I created a few classes and one class called jitPod.Api.toServer.additionalConsignments and realised even before I did any work,, that the word "Api" (note capital A) needed to be "api" (all lowercase)
it would not allow copying the class to the lowercase name because the directory already exists (i understand that)
so I exported the class to an XML, edited the xml to become lowercase "api" , deleted all the classes (and directory name) and re-imported the class.
We have a global with 65 million entries. All we are doing is just iterating through each entry to find out the total no of entries. It is currently taking 110 minutes. Is this something normal? What can we do to speed up this process? Below is the program for just iterating each entry in the global.
s sub=" ,count=0 f{ s sub=$o(^YYY(sub)) q:sub="" s count= count +1 } w!, "Total Count:"_ count
As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).
1. Get it by as a property of an instance with "Object access":
ClassMethod GetPropertyForID(stId As %Integer) As %String
{
set obj=..%OpenId(stId)
return obj.StringData
}
2. Get it as a value of a column of the record with "SQL access":
Some may think it's a strange / daft idea, but just today the Raspberry Pi folks have announced that they've now sold more than 10 million of them..and counting. That's a huge potential marketplace, and a great platform for getting people to hear about Cache and try it out. Given its focus on the education sector, another great way of getting heard about.
All responses are appreciated. I am new to both scripting and CACHE so please bear with me. I am setting up a nightly backup script for freezing cache then backing it up and then thawing it back out. Currently when I enter the freeze command I am getting a response of access denied even though my id has %all access. I've tried passing the userid/password as a parameter in the externalfreeze command and passing it from a file. I've used my id and lastly I used the _system id in the file. What ID should I use for this or am I passing it wrong?
I want to consume external websocket api, URL looks like this:
wss://site.com/ws/v2/?&token=<token>
Checked with external tool (Simple WebSocket Client) that websocket works and I can consume the data.
In Cache the relevant functionality is offered by %IO.Socket class.
set sock = ##class(%IO.Socket).%New()
set sock.SSLConfig = "MyEmptySSLConfig"
set sock.TranslationTable="UTF8"
do sock.Open("site.com/ws/v2/?&token=<token>","443", 10,.sc)
I would like to examine the contents of my OBX-5 field and not route the message if it contains alphabetic characters. I've tried various combinations of the Match and Contains functions, with no luck. Should I be using the COS ? operator or plaini regular expressions?
Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.
We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:
I'm trying to understand $ZF function, but only documentation isn't enought in this way. So my question is is there any possibility to get enviroment variable by this function into ensemble?
I've tried this as example from ducumentation, but there is an error and I don't know why...
