#Globals

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".

Hi,

I use cache 5.0 and access cache through OpenVMS.

The disk-space under a particular namespace has grown up in size due to cache.dat. How to recreate cache.dat to bring up more space back on disk?

Hi all,

I have a question about the Private Global Blocks when viewing a process's details. This number is growing while my process runs - is this due to variables, process-private-globals, or both?

Thanks

I ran %GSIZE and my ^cacheStream global is very large. How do I go about

1. Evaluating what data is in the global.

2. Clean it up.

Thanks!

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

Let's imagine I have a global like this:

^Users(12, "SETTINGS", "IsAllowed") = 1

^Users(41, "SETTINGS", "IsAllowed") = 0

^Users(52, "SETTINGS", "IsAllowed") = 1

Now I would like to check for each user whether they are allowed, therefore I'd need to iterate through the Global. How to do that? It seems that I can't use $Order here like such:

S FF = ""
For {
S FF=$O(^Users(FF,"SETTINGS","isAllowed"))
Q:$L(FF)
W "User ",FF," is allowed",!
}

Is there any other way of doing this?

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.

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")

Out of curiosity, I was looking in ^ROUTINE global to see how routines are stored internally.

I found out that lot of nodes are displaying "~pointer" as associated value (eg: instead of a string).

What are those pointers ? My guess is that it references some cache internal structure (eg: some nodes inside a B-Tree).

Is there a easily way to see what is behind ? Are pointers useful for user globals or is this something purely internal to Cache database ?

I'm working on a task where I need to apply journal file records to another database. I can't use Journal.Restore class methods as I need to perform some data transformation, therefore I'm reading journal file record by record using %SYS.Journal.Record API.

It seems that there are only few journal records that I need to process, namely:

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.

Dear Community,

i need help to access to a Global like ^name over ODBC (SQL)
i will visit this global in a loop from a php site. It a access over SQL or ODBC possible?

Thanks for help and marry Christmas

Hi, I work on my application and I want to develop rules for extracting values from my database but i've any idea:

I want to order my records by the most recent timestamps values with profile_id and biometric type as keys, after comparing them with my personal program date (when the timestamp > at my fixed date : an alert message is sent to the patient)

you find here the attached screenshots for my to databases. thank's

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?
