If you want to dynamically serve images as a property of JSON then there is no perfect encoding solution. One method used frequently is to Base64 encode the image. Whilst there are some negatives to doing this, such as data inflation, there are some positives to working with Base64 images inside the browser.

Let's say you have an image placeholder on a web page...

I have an Ensemble installation with an FTP business operation which I would like to connect to a server over SSL in explicit mode (see also: https://www.rebex.net/kb/tls-ssl-explicit-implicit/default.aspx). I keep running into timeouts while attempting to do this via Ensemble. Does Ensemble actually support SSL in explicit mode??? Because I can't seem to find any setting where to switch it on.

Logging

Hello, evrybody, I'm writing one project using CSP("OnPreHTTP"), and also REST angular. At the beginning I wrote purely on csp, then I decided to use angular for the flexibility of the client part. Now I can not design logging, I created a table App.Log with properties

TPC-E in Caché

I work in a small development company that uses Caché as a database. In some support cases I have doubts about whether the client's infrastructure environment is not affecting Caché's response time. Reading a bit about comparing installations in different environments, both in production as testing and homologation environments , I understood that the TPC-E is a benchmarking method accepted in the market.

Hello; We are managing several Ensemble instances on several servers. One server has 4 instances, and two other servers have one instance each (those are production servers). We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

How to avoid dirty read

I get two methods below: I would run both methods concurrently.

However, the "testRead" would always read the uncommitted results from "testInsert".

Anyway to avoid that? Thanks.

ClassMethod testInsert()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED, READ WRITE)
  &sql(insert into Test.Table(AttrA,AttrB,AttrC,AttrD) values(1,2,3,4))
  hang 15
  &sql(ROLLBACK)
}

ClassMethod testRead()
{
  &sql(START TRANSACTION ISOLATION LEVEL READ COMMITTED)
  &sql(select count(*) into :ans from Test.Table)
  &sql(COMMIT)
  w !,ans
}

Is it possible to make the cache terminal available over a mirrored vip address for a healthshare mirrored environment? So that connecting to a terminal for a mirrored environment will always connect to the Live Node?

I'm looking to write a Powershell script to run against the system and need to connect to the Live Node in a mirrored setup. Is this possible or am I going to have to log onto each node to establish which is Live. Or does this even matter?

Recordmap within a BPL

I have a text file that is fixed width delimited and am using a BPL to process this file, ultimately performing a transform from the text file to an HL7 message. I created a DTL, mapping from the recordmap to the HL7. In my BPL, I am performing some loops and other logic (that all is working). My issue is what to do when I perform the Transform.

Greetings to all! Faced with such a problem, I ask for help, someone with great practical skills I think has already implemented this. The task was not to delete any objects from the database, but somehow mark this data deleted by client, because of this, I added Property Deleted As% Boolean [InitialExpression = 0]; in the class. And in the redefined method %OnDelete:

Hi guys,

I'm trying to immigrate some of my HealthInsight dashboards and pivot tables to another HS instance.

In some pivot tables, I defined them with a set of calculated dimensions defined in the analyzer, e.g as below:

Then when I exported the cubes and pivot tables in used to my new envirmonment. When I open my pivot tables again, the calculated dimensions are missing and hence my pivot tables no longer work:
