Error Compiling class

Hi,

When I try to compile a specific class it fails and gives the below error message.

ERROR #5002: Cache error: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
> ERROR #5030: An error occurred while compiling class 'ClassNameHere'

Is there anything I can do to fix this issue?

Thank you in advance for your response.

SQL CLASS NODE SYNTAX

I HAVE A NEW SQL CLASS THAT DISPLAYS ENTRIES BASED ON THE FIRST 2 NODES OF A GLOBAL. I FOUND OUT THAT THE CLASS ALLOWS FOR AN ADDITIONAL NODE(s) TO BE INSERTED IN THE "User Specification Node:" along the delimiter and the Piece in the NewStorage Map1 for "ModifyDDDD" shown below. it is not working.

InterSystems FAQ rubric

By default, the order of columns in a table is determined automatically by the system. To change the order, explicitly set the order for each property using the property keyword SqlColumnNumber when defining the class.

Example:

Property Name As %String [SqlColumnNumber = 2];

Please see the documentation below.

New to Python. Attempting to use pypyodbc to select data from a table in one Cache database, and inserting into a similarly configured table in another. Process works fine except for tables containing Date types. NULL values in date columns are handled without issue, but when data is present, insert fails with:

An error occurred: argument 7: TypeError: 'NoneType' object cannot be interpreted as an integer.

Hello everyone,
so lets say i have the following:

Hello
Q
say(arg)
w arg
Q


and i am trying to execute it by its name such as:


s a = "say^hello"

*execute the name inside a*

now I know for a fact that if say were written without any argument then do @a would work!

but I can I pass an argument in this case?
I don't want to use Xecute because I am in need of really high performance code.

Hi,

I have a archive backup of a Cache database. I was able to restore the database but having trouble navigating through the globals, classes, namespaces .??? I am not a Cache user and/or developer so I am a bit lost. I am used to relational database such Microsoft SQL but not Cache which to my understand is a different breed of database. If you are looking for some extra money to help me extract some of the data I need i would be greatly appreciated.

I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.

My first question is whether this is actually necessary?

I'm running a query, joining nine tables together. When I run it with a SELECT COUNT(*) I get about 200,000 rows. When I run the SELECT with the columns I want, I get about 2,700 rows. Is there something inherent with the queries that limits the result set size, or anything I can do to make sure I'm getting back all the results? Rather, than trying to run it about 100 times limiting all previously gotten accounts.

So I know we can run routines using both XECUTE or @
However both of them run slower than just running the routine without it. (that is because as far as i understand, XECUTE command for example will re-compile before running?)

the question is: how can I run a routine by name - and keeping the performance as good as possible?

I’m trying to connect to an InterSystems Caché database from my local development environment using an IPv4 address. Most examples I’ve found show how to connect using the ODBC driver with the localhost or the default IP address (127.0.0.1). However, I want to know how to connect using my local IPv4 address.

Here’s what I need help with:

Hello,

I'm trying to carry a custom error from one business process to another.

BPL:LookupClass fails it's lookup and a custom error of "Lookup XYZ" is generated.

Generate JWT token in Cache 2018

Hi,

I try to generate JWT tokens in Cache (not in IRIS).

In IRIS I managed to generate tokens using ##class(%OAuth2.JWKS).AddOct("HS256",secret,.jwks).

But In Cache there is no such routine.

Could you provide me a place to find an example how to use JWT, please ? I am interested to generate a token in Cache, send it to javascript client, and read a token provided by the client and check it is valid.

Kind regards,

Alin Soare.
