Where is my global stored?

It's well-known that namespace global mapping helps us to write code independent on database storage details (Caché instance name, directory path). But sometimes we can face problems accessing an unsubscripted global which has subscript level mapping (SLM) defined. Most of such cases are evident and associated with administrative tasks that should be done on database level, but some of them can confuse even an experienced developer. Just to start:

Source Control Hooks and Atelier

So another topic that has been of interest to a number of people since the beta was put up last week is in regard to Studio Hooks and Atelier. This requires a bit of background and then some discussion of how the architecture of Atelier necessitates some changes and then what our current thinking on the subject is.

I realize that Cache Studio is the standard method to edit routines. However, some clients make it difficult to access their server that supports Studio. Is there an editor that can be run from the programmer prompt that allows simple WYSIWYG editing of routines? I know there is a %Routine class that you can use to do command-line editing, but I am looking for a full screen editor.

What was the standard in OpenVMS Cache before there was Cache Studio?

Thanks!
Bryan

One of the topics that comes up often when managing Ensemble productions is disk space:

The database (the CACHE.DAT file) grows in a rate that was unexpected; or the Journal files build up at a fast pace; or the database grows continuously though the system has a scheduled purge of the Ensemble runtime data.

It would have been better if these kind of phenomena would have been observed and accounted for yet at the development and testing stage rather than on a live system.

For this purpose I created a basic framework that could aid in this task.

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Language Extensions

This is a posting about a particular feature of Caché which I find useful but is probably not well known or used. I am referring to the feature of Language Extensions.

This feature allows you to extend the commands, special variables and functions available in Caché Object Script with commands, special variables and functions of your own. This functionality also applies to other languages the Caché supports at the server, including Caché Basic and Multivalue Basic.


Why would I need or want to add new commands ?

I have been asked to assist in the planning of the a new server for our database, which we will be changing operating systems from OpenVMS to Linux (RedHat distribution). However, its difficult to find material regarding what would be recommended, which is likely due to the database being proprietary.

In looking at the information provided below and hoping to decrease processing time, would anyone be able to recommend type of configuration we should have for the new Linux server? Please feel free to ask any clarifying questions.

A short post for now to answer a question that came up. In post two of this series I included graphs of performance data extracted from pButtons. I was asked off-line if there is a quicker way than cut/paste to extract metrics for mgstat etc from a pButtons .html file for easy charting in Excel.

See: - Part 2 - Looking at the metrics we collected

Ens.StreamContainer

Hi All,

I am fairly new to Ensemble and I wanted to know I have inbound business service (EnsLib.File.PassthroughService) which is looking for pdf files once it finds a pdf file (within the business process) it needs to find the associated xml file which would be in the same directory. Once both of these files are found they need to be sent to the business operation and deleted from the source (EnsLib.File.PassthroughOperation).

I searched to see if there was a previous question on this, but I didn't quite find anything. Please link if you think this has been answered before (I have a feeling it has): what are the barriers to source control using Cache 2018 and Studio?

Hi,

When Creating a custom security role, what privileges do I need to add to it, in order for the users that I grant him the role, to be able to use

dynamic SQL to perform read only queries on all tables in a namespace?

I have a security role, that contains the %Service_SQL privilege,

And yet when I connect to a terminal and try to run an SQL query using dynamic SQL , I get a "user is not privileged for the operation" error.

The MONITOR process (also called the Caché Monitor) scans the messages in your cconsole.log file and sends you emails based on the severity of those messages. The MONITOR is configured using the ^MONMGR utility in terminal.

The MONITOR should not be confused with the similarly named System Monitor, which checks a variety of system health and performance metrics and can log messages regarding them to the cconsole.log, where they can then be scanned by the MONITOR.

I followed the First Look instructions and tried to run a Docker container with the below command:

> docker run --name iris --detach --publish 52773:52773 --volume /Users/docker:/external --env ICM_SENTINEL_DIR=/external iris:latest --key /external/iris.key --before "/usr/irissys/dev/Cloud/ICM/changePassword.sh /external/password.txt"

It returned with a container ID and an error message:

I have a lookup table and record batch Table I would like to do a count on the records stored in that batch by counting the number of records in that batch that have a certain key on the responseKey column. This column keys are stored in the look up table for comparison. So I would like to do a join sql pivot that will use my keys stored in the lookup as columns and count as values

so far I have managed to do this but this is not efficient I would like to fire that sql once not on every count

HL7 segment query using SQL

I'm trying to get a count of specific message type with a specific entry and thought I could build the query in Message Viewer but this does not provide counts (as far as I am aware). So when I take the SQL from 'Show Query' it omits the segment criteria as the code shows below.

I have attached the criteria that has been excluded. Is this possible?

Thank you
