Hi,
I've read into console.log that there is some problems writing the global Task History
09/13/18-09:33:00:109 (9052) 0 Error al escribir en global de historial de tareas - Error (ERROR #5002: Error de cache: <DATABASE>%SaveData+20^%SYS.Task.History.1 ^SYS("Task","HistoryD",66179),c:\intersystems\healthshare\mgr\)
I have a global that defines the instance that Ensemble is running under. I want to use this as part of another Global so I don't have to hard code a path.
For Example
I am still working on a generic task where I need to apply journal file records to another database.

The forth in the trilogy, anyone a Hitchhikers Guide to the Galaxy fan?
I'm working on a task where I need to apply journal file records to another database.
Hi,
I wonder if you could help me with a problem with persistent globals and journals.
Hi,
I'm trying to export a global with this library %Library.Global with this call:
Hi! I have a local project written on Cache and Atelier on my PC. I need to move it to notebook.
Hi:
I'm looking for some help with JSON notation for a global structure. I need a way to represent a global structure in JSON where the global structure both has a value at a given node as well as sub-nodes.
Is there a way to reduce the size of a CACHE.DAT file after a major reduction in global content has been performed?
Thx... Larry.
Hi.
The message is received a few times a day.
On documentation, this ^ISCSOAP^is log to service SOAP, but why send to cconsole.log?
I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:
Is there something in Cache that is equivalent to partitioning a table in Oracle? I'm trying to break some big tables into groups so that the most frequently accessed data is faster to retrieve.
Is there a way to pull a user name and password from the Credentials list that is kept in Ensemble? Right now I have a LDAP user that I have hard coded into my ZAUTHENTICATE, which I would like to get away from.
Hi Guys,
I would like to know, how to setup a global structure in Cache classes storage type.
I want to set a global like below in Cache classes using Storage methods.
Some of our interfaces use globals for lookups, but we are currently looking at putting a groups of (document) interfaces in a separate production with a shared ‘Default Database for Routines’ to reduce code duplication.
Hi, Community!
Consider you move data from one server to another or make a deployment with persistent data. What do you do with index globals?
I have a classname and a property name. I want to know, when I get object value directly from a global, which property corresponds to which position in the $lb structure.
Here's what I got so far:
I have two databases, and both of them have a global ^Data with subscripts going from 1 to 10 000 000.
I want to get one database with global ^Data but with subscripts going from 1 to 20 000 000.
Since each db is around 100 Gb and they are on a different hosts, what's the best way to merge them?
Hi,
I have a class with around 400k lines and 60 columns. Class storage is Cache SQL storage (Mapped from a global).
I want to create multiple indices on certain fields.
Is there a way to omit or skip rollback of some data changes during a transaction rollback? Maybe some sort of "autonomous transaction"?
Does anyone know of a utility to compare two databases (i.e., CACHE.DAT files) and find globals/subscripts that are different between them?
Hi all,
I need to create a routine to modifiy some values in a global.
My first attempt was:
Hi,
I use cache 5.0 and access cache through OpenVMS.
Hi, colleagues!
Consider you need to put some (less than 1GB) data to an indexed array and do some data manipulations and calculations with it.
Should I prefer global or local for it?
Have very little XML experience and have been able to manually create output. Have a need to take data that I store in a M global (example: ^TML("HDATA", ) and out put it in CCDA XML format.
Globals, these magic swords for storing data, have been around for a while, but not many people can use them efficiently or know about this super-weapon altogether.
If you use globals for tasks where they truly shine, the results may be amazing, either in terms of increased performance or dramatic simplification of the overall solution (1, 2).
Globals offer a special way of storing and processing data, which is completely different from SQL tables. They were first introduced in 1966 in the M(UMPS) programming language, which was initially used in medical databases. It is still used in the same way, but has also been adopted by some other industries where reliability and high performance are top priorities: finance, trading, etc.
Later M(UMPS) evolved into Caché ObjectScript (COS). COS was developed by InterSystems as a superset of M. The original language is still accepted by developers' community and alive in a few implementations. There are several signs of activity around the web: MUMPS Google group, Mumps User's group), effective ISO Standard, etc.
Modern global based DBMS supports transactions, journaling, replication, partitioning. It means that they can be used for building modern, reliable and fast distributed systems.
Globals do not restrict you to the boundaries of the relational model. They give you the freedom of creating data structures optimized for particular tasks. For many applications reasonable use of globals can be a real silver bullet offering speeds that developers of conventional relational applications can only dream of.
Globals as a method of storing data can be used in many modern programming languages, both high- and low-level. Therefore, this article will focus specifically on globals and not the language they once came from.
