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

Documentation.

Hello,

I have a question about how to set the value of a radioSet. Yes, I know -- the documentation says that setValue can be used "client side", but gives no example. Plus, I'm trying to set the value of a radioSet in %onAfterCreatePage, which is a Zen method? Server side method? I'm not sure.

In my Zen page I create a radioSet like this:

NewBie's Corner Session 17 New command

NewBie's Corner Session 17 New command

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

New command

The New command limits a variable's scope or range of use. In theory the New command is simple, in reality the New command is powerful and needs to be respected and understood. In Caché ObjectScript and MUMPS an entire chapter is devoted to it.

There are three variations of the New command:

Hi all,

We're creating a series of RESTful APIs that output data from a Cache database (made up of global storage that we've mapped to classes). I'm running into some problems with object-to-JSON conversions when relationships are involved. Eg:

ParentClass has children relationship to ChildClass

ChildClass has parent relationship to ParentClass

I experience this constantly with Cache SQL. Especially when querying the ATNA log.

SELECT TOP 400000 * FROM HS_IHE_ATNA_Repository.Aggregation ORDER BY ID DESC

That took 12 seconds. I then upped the number to 500,000 and it took 185 seconds.

Shouldn't the execution time scale proportionately?

If I run the 500,00 query again it takes 2.4 seconds.

Does anybody else have problems installing the Caché 2017.1 FT for Win_x64?

I'm getting an error "Unable to execute the required file: The following system error has occurred: The system cannot find the file specified. (2)"

This is happening with the very latest version (build 726) and the previous one ( build 720), whereas the builds before were fine.

I've uninstalled Caché to see whether it was an upgrade vs clean install problem but it makes no difference.

Deciphering Error Messages

When deciphering an error message (<MAXSTRING>main+45^LBZNSJHCACUPLB), my understanding is the error offset is 45 lines from "main". If there are "go sub" entries within this 45 lines, do you count the lines in the "go sub" section or do you do a straight count of lines ignoring the "go sub" section?

I have a web application with html, css, js files (no ZEN/CSP).

Problem: after I update them on a server, Caché still servers old and cached version (browser Cache is disabled).

There is a manual cache purge in Gateway Settings, of course, but is there an automatic solution?

I'll be okay with disabling cache server-wide, but an application-wide solution would be better.

I don't want to host web app on a separate web server.

Here's my web app config:

Hi,

We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.

We are ready to re-write the code in Zen also if it supports that feature.

Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.

Thanks

Hi,

I'm unable to locate a set of instructions that would allow me to encrypt the traffic to/from the Cache' Management Portal (that is - run it over HTTPS)

I am referring to the Management portal as hosted by the private Apache Web server instance installed with Cache. (I know how to do this for regular web sites hosted on, for example, IIS).

I would imagine the steps would involve, (a) enable SSL on that apache instance and (b) deploy certificates into the Apache web server.

Does anyone have a step-by-step guide on how this is accomplished ?
