#Caché

Hi,

The command "##Class(Backup.General).ExternalFreeze()" switches journal files as can be seen in the following log message:

"Journaling switched to: /cache/mgr/journal/20170331.003

Backup.General.ExternalFreeze: Start a journal restore for this backup with journal file: /cache/mgr/journal/
20170331.003"

Here is a screenshot from my 2016.2 FT instance of Studio and Ensemble:

I don't recall having seen the highlighted "+" suffix on document names previously. Who can tell me what it denotes?

I originally posted this in the Field Tests group but it turned out to be a 2016.1 feature that I hadn't previously noticed. So I subsequently moved the post to the Cache group.

Hi,

After restoring all the Cache related files on a machine, I am performing journal recovery using the command "^JRNRESTO". It works as described in the document and the recovery succeeds. However, the command is interactive. Is there a way I can run it in a programmatic way? I don't want to just supply a text file containing answers to all the prompts. I am wondering if there is way I can pass all the information upfront to the command.

Thanks,

Raghu

Is there a way to generate or create a WADL or some form of service definition for a class containing REST services or on a specific URL?

here is my $ZV string "Cache for Windows (x86-64) 2016.2.1 (Build 803) Wed Oct 26 2016 12:43:35 EDT"

2. How do i convert an y Register object to JSON string ?

3. Do i need to extend from any adaptor class for 1 & 2 ?

Hello everyone. I have some problem with selecting my own globals from namespace. My task is select only globals created by me.  Follow my code, I get all globals from given namespace. 

SET NAME="" F  SET NAME=$ORDER(^$GLOBAL(NAME)) QUIT:NAME=""  DO

Please help me with excluding system globals. I need work only with my own globals.

During startup a Caché/Ensemble/HealthShare instance must consult a parameter file to get some information it needs at the early stages of startup. By default it uses the file called cache.cpf, but by adding an extra argument to the ccontrol start command you can make it use an alternative file.

how to exclude weekend(Friday) in sql statement i trade use select datediff(WK,date1,date2) but not working even i chose (Dialect mssQL)

Thank You

I've got an issue trying to write a code which should add some global mapping to already existing namespace. Here is its skeleton: 

We are planning to use Caché users on a SOAP web-service, so the WS-security tokens will be used.
It will be username and password only for now.
The passwords should expire on a regular basis and this will be configured in the system-wide security settings.
The consumer of the web-service should be able to change their password on-demand or when it has expired, via a web-service call.

For the on-demand change, I can create a service method which can be called by the consumer to change the password.

I'm moving *D globals from DatabaseA to DatabalseB.

After importing globals I need to rebuild indices for all the imported persistent classes.

Colleagues, maybe you know one command which does it for all the classes in Namespace?

Hello, we have a few hundreds of triggers to port from Oracle to Cachè for a migration project, and many of them have to change (for example, normalize a value, null it, etc) the value which is being inserted.

The documentation says "You cannot set {fieldname*N} in trigger code." , so we're unlucky.

Is there a good workaround for this ?

SqlComputeOnChange doesn't seem the best way, but I'm not totally sure: for example normalization and validation could have a better place somewhere else than a trigger.

What are the differences between a process private global and a percent variable?  Basically I have some code running in an Ensemble operation that processes requests, and it needs access to pieces of data that are scattered throughout XData blocks in various classes.  Rather than opening the XData object and deserializing the XML on each request, I opted to cache this data in a percent variable, something like:

set %MyVar(sub1,sub2) = myValue

I was wondering if anyone has combined ZEN Web Development with frameworks such as W3Schools W3.CSS Framework or the popular Bootstrap Framework? 

We are currently using Caché 2013.1.6 so we do not have ZEN Mojo installed which ships in Caché 2014.2 or later.

What would be the recommended approach if looking to integrate one of these frameworks?

I look forward to hearing your suggestions!

Hi, Community!

Is there an option to get an archived file of globals in one command. Say for:

Do $System.OBJ.Export("Class1*D.GBL,Class2*D.GBL","data_gbl.xml")

get something like:

Do $System.OBJ.Export("Data*D.GBL","data_gbl.gz","gzip")

And also to have the convenient one click way to  import it to the namespace via terminal or Control Panel?

If anyone already has this module, share please?

It would be very convenient for import/export/continuous integration purposes cause globals can be really heavy.

Due to a new project I'm getting involved inside %Installer stuff deeper than ever I'd be happy to. Most of it was pretty easy to get, thanks to documentation, articles and SAMPLES example, while I can't dig good solution for one problem. I'm trying to import and compile some classes, willing to ignore two types of errors: 5202 (NothingToCompile) and 5373 (PredecessorClassDoesNotExist - a normal case when SNMP sampling class is compiled for the 1st time, before it was registered). 

I've tried the following: 

would like to know how to execute deployments through cache terminal..Are are there any function or scripts available for deploying ? Is there any direct cache command similar to GUI-deploy that will deploy ?

Please let knoe

I have multiple namespaces in a Cache environment say NS1 & NS2. I want to add some restriction so that  a routine running in the NS1 should not access any resource(global/routine) belongs to namespace NS2.

The above restriction need for few of the clients only, so we do not want to write any custom logic in code. 

We are looking for some solution provided by Cache where we can restrict the namespace access.

Can somebody please help me on this.

Hi,

I am placing Cache instance in backup mode by using the command:

    csession <INST> -U%SYS "##Class(Backup.General).ExternalFreeze()"

and I see in the console log a message similar to follows:

"Journaling switched to: /cache/mgr/journal/20170330.002"

Now, is there a way to programmatically find out this journal file name? In fact, I am interested to find out the journal file that is switched. For example, in the above case, that would be "20170330.001".

Thanks,

Raghu

Hello,  Thanks in advance for all replies.  I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks.  I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues.  Now I am setting it up in lockdown mode with encryption and this one is testing me.  I have everything setup but my async dr member cannot connect to the primary.

Kindle Edition of Caché and MUMPS – Part II is released

All data is present and readable, albeit with some minor formatting issues.

Thank you for your patience in waiting for the kindle edition.

Hello,

We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS.  One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.

In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

Hi,

I am exploring a simple restore procedure for a Cache instance and would really appreciate any help.

Basically, I have a CentOS machine with a Cache instance and let us say I backed up all the mount points where Cache data is located (install dir, DAT files, journals, WIJ etc). On another identical machine (without Cache installed), I mounted all these file systems exactly using the same mount points so all the data is back with the same paths.

    In the previous article, I had just started working with Arduino, and got a meteorological station to show as a result. In this article, let's go further: we will set  up authentication via RFID cards and Arduino against the InterSystems Caché  application.

Does there exist a User Defined Language pack for Caché ObjectScript for use in Notepad++? I'm hoping some friendly developer somewhere may have created one . http://docs.notepad-plus-plus.org/index.php/User_Defined_Language_Files

Hi everyone,

I've created an Identicon Generator inspired on Fabio GonçalvesCaptcha Validator.

This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)

Examples:

First one:

Will generate this:

And this:

Will generate this:
