I have table

CREATE TABLE nodes (
        name VARCHAR(50) NOT NULL, 
        parent VARCHAR(50), 
        PRIMARY KEY (name), 
        FOREIGN KEY(parent) REFERENCES nodes (name) ON UPDATE cascade
);

I put some data

INSERT INTO nodes (name, parent) VALUES ('n1', NULL);
INSERT INTO nodes (name, parent) VALUES ('n11', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n12', 'n1');
INSERT INTO nodes (name, parent) VALUES ('n13', 'n1');

Let's delete all

DELETE FROM nodes;

Nope, no way.

SQL Error [124] [S1000]: [SQLCODE: <-124>:<FOREIGN KEY constraint failed referential check upon DELETE of row in referenced table>]
[Location: <ServerLoop>]
[%msg: <At least 1 Row exists in table 'SQLUser.nodes' which references key 'NODESPKey2' - Foreign Key Constraint 'NODESFKey3', Field(s) 'parent' failed on referential action of NO ACTION>]

Based on your experience, do you know any reason why IRIS would enter a deadlock/hang state ?

When such thing occurs, it's no more possible to connect to Portal or Studio, despite IRIS service (IRIS.EXE processes) being still active. CPU/memory/network usage are usually very low (eg: it does not occurs because server is overloaded). The only fix is a full restart of IRIS (eg: by clicking on IRIS icon in notification toolbar and choosing appropriate action).

Attempting to setup an outbound (I'm querying out, not querying the IRIS db) SQL connection. I am connecting to a PostgreSQL database, name "hl7interface".

I have setup the odbc.ini file at /usr/local/etc with the following contents:

[HL7Interface2]
Driver = PostgreSQL
Description = HL7 Interface DB
Servername = localhost
Port = 5432
Protocol = 7.4-1
#userName = postgres
#Password = <real pw here>
Database = hl7interface
ReadOnly = no
ServerType = Postgres

I have set the /etc/odbcinst.ini file with the location of the PostgreSQL driver:

we are looking at replacing our VMS system with Linux :-( yes a sad day!

now the question has become should we go with Intel or AMD. personally I think Intel is the way to go for several reasons.

has anyone seen or heard of an AMD being slower or there is a definite performance of one over the other.

thanks for your feedback.

first our current environment which will be copied over to the new platform

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

JReport Catalog

Hi,

I am trying to use a Jreport catalog which had been saved by a different user. But when I save the catalog I am getting an error "Access is denied".

So does that mean same catalog can't use by different users ?

Can anyone please provide a solution for the Jreport same catalog can use for different users. ?

Thanks

Jude

I know that you can use Do $SYSTEM.SQL.Schema.ImportDDL() to insert sql files into IRIS however I was wondering if there is a way that I can upload .sqlite files into iris? I have about 20 .sqlite files that I need to get into my database. I tried using the ImportDDL method but it said "SKIPPING non-SQL SOURCE:"

I built a dashboard to show hourly instrument capacities based on a term list. The term list consists of the TestInstrumentID and the number of tests that instrument can perform in 1 hour. The calculation works correctly and the data is accurate but periodically if you go to check the dashboard the percentages all get changed to 100% across every hour. If you check it later or add an additional site to the filter then the percentages correct themselves. I don't know what's causing this or how to troubleshoot it because it does calculate correctly but is not consistent.

Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.

Hi,

I have a test version of Cache installed on my laptop, but I cannot get logged into the database. I think my ID may be locked due to too many password failure attempts. I have not changed the Admin password or SuperUser password. Does anyone know what the default password would be for the Admin and/or SuperUser Id's? Or if someone knows how I can get in and unlock/reset my password, it would be much appreciated??

Thanks,

Larry Cardinal

Happy New Year to all

Hello all,
I am creating a REST API with a spec-first approach. However, I am using the try-catch method to handle any exception if any occurs. But whenever any error related to syntax or something occurs, we get internal server error

"errors": [

"code": 6220,

"domain": "%ObjectErrors",

"error": "ERROR #6220: Internal Server Error",

"id": "InternalError"

}

],

"summary": "ERROR #6220: Internal Server Error"

I have a production with one Business Host - a Business Service which I need to scale automatically to consume ~80% of CPU time.
Business Service pulls data from a (non-FIFO) queue so that I can adjust pool size without any issues.

So far, I'm planning a different BS running every X seconds and sampling CPU with $system.Process.GetCPUTime() and scaling the pool size of the main BS up/down based on that metric.

Has anyone tried something similar? Any advice/code samples would be appreciated.

Lisence usage suddenly spikes

Sometimes, our available license will drop and upon close inspection, it is caused by one or two users occupying 50 or so licenses, and we believe that if there were more, they were all gonna be used up. This occurs randomly. As is illustrated in the following figure.

Out cache version is 2016.1. It is serving a health care web application. Our web browsers are exclusively IE-11.

Read-only .cls?

Hi, could someone tell me please how can I "unlock" a .cls file which author is Intersystems? I want to make some modifications and add some trace messages there. The file resides in the HS.FHIRServer namespace and it looks like read-only

there is a setting in VSCode "objectscript.export: {noStorage: ture} " allow export cls from server to client, without storage definition.

However, wheneven I complied and save cls in my vscode client, the storage definition was added back. If I don't want it, I have to deleted the part manually.

Does anyone have something to teach me? thank you
