#Caché

30

  

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

Documentation.

Let's say I have a global named ^a and I need to export its nodes 1, 2, 3, 5 only.

Currently I write something like this:

Write $SYSTEM.OBJ.Export("a(1).gbl,a(2).gbl,a(3).gbl,a(5).gbl", "C:\Users\eduard\Desktop\a.xml")

Is there a way to write it shorter? I want to write global node once and list all the subscripts I need.

Creating a Dummy SOAP Web Service

A “Dummy” SOAP Web Service

When dealing with SOAP in Caché, it is sometimes necessary to debug errors by directly accessing (and sometimes editing) the XML which is sent, i.e. the SOAP request and subsequent SOAP response. If you’re debugging a Caché web service, it is often useful to use a tool such as SoapUI (https://www.soapui.org/) to manually create and control the SOAP request, so that the effect of adjustments can easily be seen on the Caché web service.

Hi all,

Do anyone know how to force to close the CSP connection used before redirecting to a different page so a new connection ( and therefore a new session id) is generated?

The idea is to generate new CSP session once we log off our application so the session identifiers are different.

Best Regards

I know %CSP.Daemon is supposed to clean up old CSP sessions (?). In my management portal, under System/ License Usage, I see 33 "Units" used (and there are 33 licenses in use), but usernames from old IP address and that are not being used. Their active times are often in the millions of seconds. They are not "on" the system right now.

At most, only 3 users are on the system right now.

Are these supposed to be cleaned up? Can I clean them up programmactially, and how would I know if they're not active?

Thanks,

Laura

Caché on new hardware

A question from Benjamin Linden:

We are looking to upgrade the hardware for our server.

Do we need to buy a new Caché license? Or can we keep using the one we have?

Dear Colleagues,

Recently I am working on a Cache project should enable the customer, to update our Cache application independently from us. Our idea is a client (preferred .net) application that will copy all the necessary Cache stuff (classes, routines) into a cache database. For this, we are looking for the appropriate technology – in old times this would be a CacheDirect.

If a user simply closes a tab (running a web application), is there any good way to ensure that the license is released AND the login cookie is destroyed?

I found that if the tab is simply closed without first logging out of the application, then 1) the license hangs around forever, and 2) if the user then opens a tab, he is already logged in.
