I would recommend seeing what's stored in the database, for this, you can use %GSIZE and count all the globals,
and you may find which global(s) so big.
And you can stop the server, delete CACHE.DAT, and start it again, and in this case, it should be recreated anyway
Try these two variants
write $extract($random(10000) _ "0000", 1, 4)
write $random(10)_$random(10)_$random(10)_$random(10)You should know that even in such a database with switched-off journalling, data will still appear in journals if data changed in transactions.
My question was, just exactly about that data stored for Ensemble, should I keep it in a mirror, or, may omit it?
Could you share your connection settings? It should use super port 1972

What the component did you use for connection?
There are a few technologies that was deprecated with IRIS, or under an additional license option.
Did you see these examples? I'm not an expert in .Net, but as I understood the documentation correctly, you must pass stream as is to .Net method with byte[] as is, and the Gateway should map it, for you.
For performance reasons, it's possible to define an Index in a way, that some of the columns will be as part of the index itself, just for search, and some data could be in the data part of that index, which will be used to display in the result if requested. So, if your index is somehow corrupted, the SQL engine will expect the values there, and will look for it, so, it will not go to the place where the data originally seat. And as a result, you may not see some of the data in the output rows.
Sure, it’s possible to do so. React application is just a frontend side, and IRIS itself can be as a backend server. Or you can write backend server on some other language, e.g. NodeJS, Python, Java or .Net. Which will connect to IRIS as a database.
you can look at my Realworld project, in particular realization of backend server. The project itself offers, the wide variety of frontends and backends on different languages, and with using different databases. So, you find React frontend which will work with backend on IRIS.
and look at my article about this project
In any way, in such cases the first thing is would be to try to rebuild indexes. It should not take to much time, or even if you are able to do it, purge indexes first, then rebuild from scratch.
if it’s still shows differently. In this unexpected case, I would likely to see the your table definition.
It looks the issue with indexing. Did you add some new indexes while you already had some data?
IRIS requires to manually rebuild index after adding or changes.
look at the documentation
If you currently have running instance with all the namespaces together, for some time, you may look at ^GLOBUFF, to see how your global buffers used by now, and decide how to split that buffer for each instance.
Switch to Docker will have much more pluses in your case.
It’s a binary file and it’s contest for the current context not so important, what’s important is an ownership of the file. So
ls -la /usr/local/etc/irissys/iris.regCheck the ownership of the file iris.reg, which should be in /usr/local/etc/irissys
The owner of this file is supposed to be used to control IRIS
You would need to copy %JSON package from the latest IRIS version, but not sure if it will work.
Depends on what are you trying to achieve.
Import as is, with an iterator
Class User.Test Extends (%RegisteredObject, %JSON.Adaptor)
{
Property name As %String;
ClassMethod Import()
{
Set data = [{
"name": "test1"
},
{
"name": "test2"
}]
Set iter = data.%GetIterator()
While iter.%GetNext(.key, .value) {
Set obj = ..%New()
Set tSC = obj.%JSONImport(.value)
Write !,obj.name
}
}
}Import with a wrapper object
Class User.TestList Extends (%RegisteredObject, %JSON.Adaptor)
{
Property items As list Of User.Test;
ClassMethod Import()
{
Set data = [{
"name": "test1"
},
{
"name": "test2"
}]
#; wrap to object
Set data = {
"items": (data)
}
Set list = ..%New()
Set tSC = list.%JSONImport(.data)
For {
set obj = list.items.GetNext(.key)
Quit:key=""
Write !,obj.name
}
}
}jsonProvider was invented before native JSON support was added. And there is no reasons to use it already. If you need a JSON representation for an object, look at %JSON.Adaptor
Could you try to open URL in any Browser.
http://192.168.245.118:57789/api/atelier/
It should offer to enter login and password, in a modal dialog, and after that should some JSON.
In your case, looks like it responses with some HTML, probably with some error, like not found 404.
Some info about blocks, in this article and others in cycle.
Jeffrey, thanks. But if I would have only 16KB blocks buffer configured and with a mix of databases 8KB (mostly system or CACHETEMP/IRISTEMP) and some of my application data stored in 16KB blocks. 8KB databases in any way will get buffered in 16KB Buffer, and they will be stored one to one, 8KB data in 16KB buffer. That's correct?
So, If I would need to separate global buffers for streams, I'll just need the separate from any other data block size and a significantly small amount of global buffer for this size of the block and it will be enough for more efficient usage of global buffer? At least for non-stream data, with a higher priority?
This is only for external access to this label, without it, you would not be able to call this from terminal or from another routine or class.
Curly braces makes it private by stack.
Having multiple different global buffers for different block sizes, does not make sense. IRIS will use bigger size of block for lower size blocks inefficiently. The only way to separate is, to use a separate server, right for streams.
I suppose, the issue in your settings.json, which I see you have opened. Could you check if it's really a JSON, and correct? If possible, could you attach the screenshot with it as well?
Could you attach screenshots? It's not clear when you get the error.
I've mentioned above a system with a significant amount of streams stored in the database. And just checked how global buffers used there. And streams are just around 6%. The system is very active, including files. Tons of objects created every minute, attached files, changes in files (yeah, our users can change MS Word files online on the fly, and we keep all the versions).
So, I still see no reasons to change it. And still, see tons of benefits, of keeping it as is.
Fragmentations issues, with SSD disks not an issue anymore.
But in any way, I agree with storing files in the database. I have a system in production, where we have about 100TB of data, while more than half is just for files, stored in the database. Some of our .dat files by mapping used exclusively for streams, and we take care of them, periodically by cutting them at some point, to continue with an empty database. Mirroring, helps us do not to worry too much about backups. But If would have to store such amount of files as files on the filesystem, we would lose our mind, caring about backups and integrity.

In most cases, it’s enough to just create empty certificate with just default values.
how do you use it?
