InterSystems IRIS Experience

Syndicate content 21 

During migration from Caché to IRIS I can preview a situation where some instance
have migrated to IRIS while others are still on Caché.
For various reasons this may be in place for some weeks or even months as the big bang isn't feasable.

So far I found a lot of statements related to mixed endinans,
but nothing related to cross operation beween IRIS and Caché.

?? any hints ??
?? any experience ??

Hi all,

One of the most useful features for me in IRIS was the queue page. From there, I could see how the different elements (BS, BP & BO) from a production were behaving, thanks to the possibility of auto-refresh every second. Great thing.

But we have updated to 2019.1 and this possibility is gone... we need to refresh manually! So, is there any way to set a parameter somewhere to have the queues status refreshed automatically?

 

Thanks a lot.

Hi,

I know of the existance of (ELEMENTS) to create an index from a list, but I actually would like to index the content of an element of a list. Is it possible?

 

My scenario:

Class:
Property Test As list of TestList;
 

Test.List:
Property Name As %String;
Property Surname As %String;

I would like to have an  index based on the TestList.Name. If I try using

Index NewIndex On Test(ELEMENTS)

it will create an index with Name and Surname in it, but I just want to have an index with the name. Is it possible?

Hi guys,

I have a customer trying to extract data from Hive. I've tried to use Data migration to migrate a table into IRIS with JDBC driver. But the migration task always fails as below

Then I tried to create a link table, the task fails too with the following error:

As IRIS was announced yesterday by Paul Grabscheid I would be highly interested to get in touch with it.

- How can we get qualified for a closer view ? 
- Where can we get some (preliminary) description + documentation.
- Is there any FT available ?

 I'm especially interested in the areas around included/embedded/attached JVM and SPARK .
