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?

Hi folks!

Want to share a lifehack with you on ObjectScript highlighiting withing VSCode for script files.

Script files are just files with lines of ObjectScript that we feed anywhere, e.g. into IRIS during Docker baking procedure.

Typical usecase - here is the Scriptfile

here is the Dockerfile where we feed it.

And here is how it looks like usually in VSCode:

IRIS Interoperability Message Bank

I heard about Message Bank when we started redesigning a Health Connect production to run in containers in the cloud. Since there will be multiple IRIS containers, we were directed to utilize Message Bank as one place to view messages and logs from all containers.
