I'm working for an organisation that is running a very old version of InterSystems Cache (5.016) which runs on AIX . The last two times we have re-booted Cache, we have encountered rollbacks. I've been asked two questions. During the rollback it was "How long is it going to take?" and after the system returned, it was "So what caused it?". My answer to both was "I don't know".

Currently, namespace Alpha is configured to use database AlphaDB as its global database. How would we go about having namespace Alpha configured to use database AlphaDB for its global database except where global ^Customers(CustomerId) has a CustomerId greater than 10M, which we would like to have it redirected to database BetaDB.

In other words, ^|"AlphaDB"|Customers contains all customers between 1 and 10,000,000; and ^|"BetaDB"|Customers contains all customers greater than 10,000,000. Any help would be appreciated.

Hi,

We are using CACHE 2017.2.1, I would like to retrieve data from Journal for killed global. Let say we have global name ^ EMP(123) with data and also have some child nodes and it has been killed by using cache kill command for some reason and we don't know who has executed this and when. My questions are below.

1) Can we get back the data of killed global from journal files,Is it possible or not ?

Hey InterSystems Community!

This is probably far-fetched - is there a way to get notified/get a piece of code triggered whenever the state of a global changes?

Now what could I possibly want with that? Quite simple! I would like to forward the content of a global (in this case the "FSLog" global written by the FHIR implementation) while adding timestamps to it - to create some sort of file-based logging for it.

Is there a way to omit or skip rollback of some data changes during a transaction rollback? Maybe some sort of "autonomous transaction"?

The issue is with error logging in transaction. For example we may have in nested calls the following structure:
TS
<some code>
<error happens>
TRO 1
<error log to database>

but if this code is in another transaction, and that rolls back we lose error data.

Hello Intersystems-Community,

I build an API and there I use $order to get the Data from my Globals.
When I first time use that API it's get an error (504 Gateway-Timout > 60 Sec.).

After 2 reloads it works with a loading time of 2 Sec.! Sounds for me like the $order is cached and it works faster. Is it true $order will be cached?

When it works, I only get the error at the next day. So it's very hard to reproduce that error. Is it possible to delete the cache for $order?

Example:

Data import/export

I am creating "models" that contain rows in several class tables called Model, Path, Node.

So, model 19 includes 1 row in the Model table, 11 rows in the Path table, and 10 rows in the Node table.

I'd like to write some utilities to "move" model 19 from one instance to another.

Variables in Global Name

I have a number of globals I want to loop through depending on a passed in string...

^A("SYSTEM")

^B("SYSTEM")

^C("SYSTEM")

^D("SYSTEM")

^E("SYSTEM")

I am passing in a string of "A:C:D"

Piecing that to pull out A,C,D, then want to use that to pull out A,C,D from above, but having problems setting the name of the global to be the name of the variable I have pulled out of the string

How do I set this?

I have tried ^varname("SYSTEM")

I am inspecting our DB globals in order to reduce sizes of the worst offenders if possible. When I come to a large global, I am interested which of its nodes are the largest. Hence code below with unexpected different results. Any explanations why are results different?

Can someone direct me to where in the documentation we can find how consumption may be calculated for global storage?

Caché Version2010.1
Operating SystemHP OpenVMS 8.4

EDIT: After receiving some responses, it seems I was unclear in my initial inquiry. I am looking to determine our rate of consumption of storage; however, I am having some difficulty in doing that.

Class changes not executing

We are using Ensemble and I added some debug logging that writes to a global and recompiled the class in Studio. However, when we send messages, the global is not populated. I have recompiled, removing the checkmark to keep the generated code so that there is only one .INT file and I verified that the code is present in the .INT file.

My question is, do we need to stop and restart the Ensemble production in order for these changes to take effect? Do I need to stop and restart the business operation that calls this piece of code? Is there something else I may have missed?

Hi there have been various posts around how to clean up globals without parent data but none have gone into how you solve these issues.

Our database is approaching 600gb in size so i am looking into how to reduce this.

We use standard purge tasks.

Our cache stream class has a global size of 2463243 from running global size so it is what i would like to tackle first.

1) is there any way i can find based on my oldest message session for where most of these globals
