Understanding process jobTpe

I have a client running cache on an AIX platform. I put together a objectscript to allow for the viewing the processes running against the database using a select from SYS.Process. One of the values I want in the view of the processes information is Jobtype but I want to convert it from the numeric value to a string value. In the Intersystems documentation there is a reference to an include file $syPidTab.inc that should include macros that make this translation. I have not been able to track down this include file.

There is a finite list of date formats that users want to use to enter a date in a form. These formats include single digits for month and day and double digits for year. The field is represented by a dateText control.

How would one get to allow a dateText control to accept multiple date formats ? I see only 3 listed here, do those include using single digits for month and day ?

After linking in Oracle Table with Field Column's Data Types of NUMBER, my updates into these table fields are resulting in data that is being rounded to 2 decimal places. I insert a record with 1234.1234 and 1234.12 is stored.

It appears Cache xDBC might be manipulating my values prior to sending to Oracle. Is there a setting or system parameter that is controlling this? If so, is there a way to relax this from occurring so the values I send are being stored in Oracle with the same values?

Hello,

We need to upgrade our cache instance from 2016.2 to the latest version.

I find the documentation about the "Upgrade Path" but I cant find where I can get the files to upgrade in the documentation.

Also I cant find how to make this upgrade, they talk about strategies but dont talk how to perform the task to upgrade.

Is there any documentation of how to make and upgrade and where I can get the files?

Hi developers,

We have just published an update to the Deltanji version control extension for Visual Studio Code.

When used in certain Deltanji workflows, triggering an automatic checkout on first keystroke could result in the developer working on an outdated copy of the code and only being notified of this later when saving their changes. In order to prevent this from happening checkout now reloads the document immediately.

Error messaging has been improved in two areas - when attempting to cancel code that is not checked out, and when trying to register new code onto a withdraw system.

We have also improved interoperability between the Deltanji extension and the InterSystems ObjectScript one, as well as its handling of multi-component objects.

If you're already a user of Deltanji then your extension with automatically update. You can find out more information on Deltanji and the latest release here.

Convert hexadecimal to base64

Hello, first of all thanks for your time reading our question 💭

We would need to be able to transform a hexadecimal string to a base64 coded one. 🔄

To be specific, our use case is this:

1º We have our hexadecimal as follows:

4C5803040101020179C3913EC3BA7C4C580708010101021824584D4C

2º We convert it to ASCII:

I'm trying to implement an OAuth2 server, but I have som issues when trying to setup JWT under OAuth 2.0->Client.

I get the error message saying "No match between server name 'localhost' and SSL certificate values 'cache'". I have set up a SSL/TLS configuration as simple as possible without any certificate files. I'm accessing my server via HTTPS with an unsigned certificate.

Can anyone point me in the right direction on how to resolve the issue I'm encountering.

My objective is to find routine's Date/Time Saved someplace inside Cache. The routine's Date/Time Modified as returned by various queries like %Library.RoutineIndex and as seen on the File Open screen is actually Date/Time Compiled last, not Date/Time Saved last. Does anyone know if Date/Time Saved is created when the Save icon is pressed or the routine is imported? Such a timestamp should be immune to subsequent compilations with no changes.

In a typical database, changing the type of a column from some kind of date/time to a string would require a degree of migration effort for existing values. In Caché, my suspicion is that this is not the case, and I could simply change a property definition from %Timestamp to %String (MAXLEN = "30") and recompile, without needing to worry about damaging the existing data stored for this property. Is this correct? Or would I find the existing data in this property being lost or corrupted?

Thanks in anticipation

Dear,

From time to time I get the following error after executing a select statement:

[SQLCODE: <-400>:<Fatal error occurred>]
[Cache Error: <<UNDEFINED>Main+65^%SYS.DBSRV *%qsc(1187,8)>]
[Location: <ServerLoop>] InterSystems.Data.CacheClient.CacheException [SQLCODE: <-400>:<Fatal error occurred>]
[Cache Error: <<UNDEFINED>Main+65^%SYS.DBSRV *%qsc(1187,8)>]

After repeating the query, the query succeeds.

How do I start debugging this type of issue?
