++ Update: August 1, 2018

The use of the InterSystems Virtual IP (VIP) address built-in to Caché database mirroring has certain limitations. In particular, it can only be used when mirror members reside the same network subnet. When multiple data centers are used, network subnets are not often “stretched” beyond the physical data center due to added network complexity (more detailed discussion here). For similar reasons, Virtual IP is often not usable when the database is hosted in the cloud.

Network traffic management appliances such as load balancers (physical or virtual) can be used to achieve the same level of transparency, presenting a single address to the client applications or devices. The network traffic manager automatically redirects clients to the current mirror primary’s real IP address. The automation is intended to meet the needs of both HA failover and DR promotion following a disaster.

Time after time on CSP Session page of our Cache 2017.2.1 installation I see that all licenses are consumed by CSP sessions of /csp/sys, /csp/sys/op/and /csp/sys/mgr applications which I assume are sessions of Management Portal. The problem is that there are only few of us accessing the Portal and as we test by browsing Portal, we can't reproduce the problem.

Is there any way to see client IP of CSP session? Any other way to approach the problem?

The problem looks very similar to the Forefox-related one but we don't use Forefox.

Hi Everyone,

I am trying to built a SSIS package thru BIDS Visual Studio 2013. My Datasource is a InterSystems Cache Database, I wanted to Import Tables records from the Datasource to MS SQL Server 2014.

As a Sanity check. I only created one Package to import one Table to MSSQL Server to try out. The connection to the InterSystems Cache Database was successful. The DSN for the InterSystems Cache Database is created in the System for 32 and 64 Bit.

Caché service does not start

Help, after a day of coding, I wanted to backup my files. I found out that alle of my 3 instances of caché refuse to start.

the error says: cstart-exe-fout (112 Service for Caché instance did not start).

Is there a way to solve this? (off course the management portal does not work either.)

I think there has been a power interruption as the battery from my laptop does not work, and the power went off before

shutdown.

Thanks in advance!

I have a cache client with a list of several servers.

One of the server is working with an IIS server that is not the Cache DB server.

The connection to the IIS server is only through https (SSL)

I tried to define the Web Server IP Address to https://some.server.name but it didn't let me to specify the https

So I tried to define Web Server Port to 443 but when I chose the SMP it's trying to open http://some.server.name:443/csp/sys/UtilHome.csp

Without installing Kerberos has anyone Authenticated a SQL JDBC connection? Currently we are using local SQL Accounts to sign onto External SQL Databases, but we are being told that we need to switch to Service accounts that live on a Active Directory Domain.

I wrote with a little help a ZAUTHENICATE to do the Authentication for Ensemble, can I use something like that to connect to an External SQL Database using a Service Account on a Active Directory Domain?

Thanks

Scott

Hi, guys,

One of my clients was required by the hospital to name their webservice operation as Action_Subject, ie. Get_PatientInfo

When I define the web method as "Get_PatientInfo" as below,

/// MyApp.MyService
Class MyApp.MyService Extends %SOAP.WebService [ ProcedureBlock ]
{

/// Name of the WebService.
Parameter SERVICENAME = "MyService";

/// TODO: change this to actual SOAP namespace.
/// SOAP Namespace for the WebService
Parameter NAMESPACE = "http://tempuri.org";

Hi - has anyone successfully used the python binding on a mac. I carried out the install instructions per InterSystems documentation and it fails completely. 204 warnings and 9 errors. Obviously this was never tested by InterSystems. Is it even worth pursuing?

Thanks

I'm just getting started with Atelier and HealthShare. I created a persistent class, then realized I didn't want it. There is information in help about resetting storage definitions, where you use 'delete' in Studio. I tried that in Atelier. It deleted the class but not the storage. I can't delete the table directly because I didn't set it to allow DDL. This was done in a development environment and there is no data in the table. So, two questions:

Send PATCH http call

I need to send a PATCH call from the server to a given url.

Until now I was using %Net.HttpRequest to issue calls for get/post/put but today I had to make a PATCH and I can't find a way to do it.

What Are You Using For Issue Tracking?

Hi, Community!

What is your favorite issue tracking system for projects with InterSystems Data Platform? What did you use and what are you using now?

In projects with InterSystems Data Platform, I worked with Redmine, JIRA, Trello. A lot of code versioning systems now have this feature too (Gitlab, Github).

Now my favorite for small and medium projects is Github, because it is simple, is very close to code (commit-issue linkage) and it has kanban).

$CASE For Long Stories

Hi, Community!

$CASE is a fine syntax sugar for "Ifs" with one-line/one-word expressions, like in docs:

SET daynum=$ZDATE($HOROLOG,10)
  WRITE $CASE(daynum,
              1:"Monday",2:"Tuesday",3:"Wednesday",
              4:"Thursday",5:"Friday",
              6:"Saturday",0:"Sunday",:"entry error")

But if my expression for a current case is a multi-line business logic? Can I use "{}" somehow or better go with "IF" instead?

Ternary Operators

Hello community, simple question. I've been able to use a ternary operator equivalent by using $select for inline if statements using this pattern:

set x = 1

set result = $select(x = 1: "true", x = 0: "false")

These can be nested and can have a lot of options. But I'm curious if there is a native way of using ternary operators in ObjectScript?

Thank you
