Can you share a bit more details, how you embedded it to Ensemble ?

Wizard - is it Studio wizard ?

And have you configured .Net gateway ? You should have it anyway, and you can configure log file, which may be contain some errors.

In a development process, you can use any latest version of Caché, and export all code to source control system, in version which you use in production. It is not so difficult as may looks. Except only if you use so old system, like 2010.1 or earlier, because export qualificator /cacheversion supports version 2010.2 and later. In this case, you should have some building process, which will be at right version, which you need. I've used this way for years, and for our client we built two versions 2010.2 and 2012.2 from the same repository. You just should not use some new features, or use macroconditions by version, except JSON, you can't use anyway if lowest version doesn't support it yet.

No. Just because most of code of this portal used static links. To change it you should change lots of classes, and even recompile some csp files.

I haven't used SSD in production yet. I'm sure there lots of people who can say more about it. But anyway as I know, all modern SSD, and even which is special for servers, now has a very big count of rewrites. So, it means, that in most cases now you should care about it at all. And fragmentation could be a problem only when you have so many empty blocks, which should be cached, but you don't have some many RAM for it.

So let's suggest you have some object with such properties (Legs=4, Fur=True, Tail=True, Attitude=100). In a global it will looks something like this

^MyPets("Cat")=$lb(4,1,1,100)

And in this case, we should have any pointer block in anyway, and while we don't have so many data in our global, yet. Type for pointer block will be 70

Block Repair Function (Current Block 3): 44
Block # 44               Type: 70 TOP/BOTTOM POINTER
Link Block: 0            Offset: 40
Count of Nodes: 1        Collate: 5
 
--more--
 
#    Node                    POINTER
1    ^MyPets                 78

But we also have not so big value for our object, and data block can store subscripts in this block, as well as a value.

Block Repair Function (Current Block 44): 78
Block # 78               Type: 8 DATA
Link Block: 0            Offset: 60
Count of Nodes: 2        Collate: 5             Big String Nodes: 0
Pointer Length:6         Next Pointer Length:0   Diff Byte:Hex 0
Pointer Reference:      ^MyPets
Next Pointer Reference:
Next pointer stored? No
 
 
--more--
 
#    Node                    Data
1    ^MyPets
2    ^MyPets("Cat")          $lb(4,1,1,100)

Or our global could be looks a bit different

^MyPets("Cat","Attitude")=100
^MyPets("Cat","Fur")=1
^MyPets("Cat","Legs")=4
^MyPets("Cat","Tail")=1

But change nothing.

Block Repair Function (Current Block 44): 78
Block # 78               Type: 8 DATA
Link Block: 0            Offset: 108
Count of Nodes: 5        Collate: 5             Big String Nodes: 0
Pointer Length:6         Next Pointer Length:0   Diff Byte:Hex 0
Pointer Reference:      ^MyPets
Next Pointer Reference:
Next pointer stored? No
 
 
--more--
 
#    Node                    Data
1    ^MyPets
2    ^MyPets("Cat","Attitude") 100 *
3    ^MyPets("Cat","Fur")    1 *
4    ^MyPets("Cat","Legs")   4 *
5    ^MyPets("Cat","Tail")   1 *

So, we can see that yes, our subscripts now stores only in data block, yes it is, but they represent here as a nodes, and could be named as branches in a tree, we still have to store data in a data block, but we also need to store information about global, that's why we can see it here. And when will get more data than could be stored in one block, this block will be splitted, and in a parent block will see two nodes, for first nodes in a children blocks.

Yes, but in this code, for me is too mach, and also, postconditionals should be quite short, like sc, and should not be more or close to length of real statement

Just found board UP, it is a Raspberry Pi compatible board but on Intel Atom. Available mSATA SSD shield. 

Looks very good as an alternative to Raspberry, where I think would be possible to run Caché.

Just noticed, that some time, my HAPI-FHIR server which connected to Ensemble, responses too long on some queries. And found that on Ensemble side, too many lock, and looks looks some of them in a dead-lock, and not sure why is happens yet.

Dmitry Maslennikov · Oct 19, 2016 go to post

Thanks for sharing this. But some comments about code.

  • postconditionals is a very good part of our language, but here is too much, and quite difficult to read such code. In this case much better will be simple if else
  • return in try block is a bad idea, you should throw an error, which will be caught anyway
  • we can do new $namespace, but in your code, this method returns to wrong namespace, look at my previous point
  • instead of $replace(database,"/","\"), use ##class(%File).NormalizeDirectory(database), in this case you should not check on OS, even you forgot some of OS's, and in this case NormalizeDirectory/NormalizeFilename, a bit better.
  • verbose mode will be better to do with a macros, something like $$$DebugInfo("some message")
  • In your code I see so many checks on errors, and looks like, after such error we should exit, but you go further. You should look at some system macroses like $$$ThrowOnError() and so on, I think you should use it. And code will much more clear for readers
  • and at the end you have some call to method checkRW, I think you should remove it, or show this method, because it's not clear what it does

And, before publishing, please change tabs to spaces, because tabs here is too big. And width of lines should be a bit less, because read such long lines a bit difficult. 

I fixed tabs here, for more readability.

I'm just looked at another examples in other dialects. I'm not so good in Java yet, and even in Hibernate, and not sure that my way is correct.

XLS, files much more difficult that plain CSV. And depends on which version you want. XLS - it is a binary format, but XLSX already bunch of XML files but compressed in one file.

You can try to use ZEN reports, which supports XLS as one of output formats.

I think not so many people know about Ultiview and even how it could be connected with Caché. 

So, in this case, you should some more details in your topic, how it connected, and how this question depends on Caché.

Dmitry Maslennikov · Oct 17, 2016 go to post

There are lots of ways how to export data in CSV format in Caché. Add here your or code, or some more information. How you did it, and after that we may help.

Dmitry Maslennikov · Oct 15, 2016 go to post

Please add more details. What HTML report? And what the final goal, you have to achieve ?
Looks like you have to use %Net.HttpRequest, but I'm not sure, because of your description.

While it is possible to do with COS, there are so many different ways to achieve it.

Most easiest and preferable way, is to write some code on server side, and call it from batch script.

To work with users, you can use class Security.Users.

Also you can look at %Installer manifest, which has some functionality about security.

Terminal scripts, can help to automate some things. And how to run it.

And even you can read this article, about COS and Linux. It is quite simple, but as an example.

I'm just repeat my answer from google groups

This process names decompile, and it is quite difficult process, and may not be legal in some cases I think. 

I saw only one very old project, for version 5 or less.

And actually answer is yes, it is possible, but we don't have such tool now. To do it, you should know exactly how works compiler, and it's lots of work.

Dmitry Maslennikov · Oct 11, 2016 go to post

Yes, Studio, it is just a part of client components for the database. You can install only studio if you want, but you should use full installer.

But you can try to use Atelier, which standalone application, with own installer.

Your clarification does not help actually. But any way, deleting any object, leave just ID on a link, and again, everything here depends on your application. In most cases it could cause for some different issues, when application have not expected deleted object. And I would recommend to use some flag like "isDeleted", which can help to hide such objects in most of places, and still have an access to the content of this object, to show if it would be needed. Completely delete object recommended only in case when no any other objects has links to this one. 

Dmitry Maslennikov · Oct 11, 2016 go to post

It is completely depends on application which you use. Some developers create their own table for users independent from Caché users.

Or maybe you talking about  HealthShare or TrakCare?
