Simple Way To Compare Streams

Is there a simple way to compare Stream data between two objects?

We have used $ZCRC to create a checksum and that seems to be work.

We have also read each line of the streams and compared them and that seems to work too.

We just think there has to be a simpler way than looping through all the lines of the stream.

Any suggestions would be appreciated.

Hello Community,

I'd like to share with you our article with @Regilo Regilio Guedes de Souza on AWS Amazon blog Automating application-consistent Amazon EBS Snapshots for InterSystems IRIS databases. Our team has created this step-by-step instruction to create application-consistent snapshots for InterSystems IRIS databases. In this article, we outline how to automate pre-scripts to pause I/O and flush buffer to disk and post-scripts to thaw I/O, as shown in the following figure:

Hello everyone!

Some time ago, I changed the configuration in SQL Runtime Statistic to "Turn on Stats code generation to gather stats at the Open and Close of a query". With this change, the CACHE base (cache/mgr/cache/) has grown a lot to reach 198GB.

Yesterday, I returned the configuration of SQL Runtime Statistic to the default which is "Turn off Stats code generation" and the cache base is no longer growing.

My question is?

Code Golf: Binary encoding!

Time for another round of code golf!

Develop a function that performs a two-step encryption process on a given string:

  • First Step: Reverse Cipher

    • Reverse the entire input string.
    • Relocate the last character of the original string (now the first character of the reversed string) to the end.

  • Second Step: Alphabetic Index Binary Encoding

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

Join JSON responses

Good morning, 🙂

I would like to ask a question, which has to do with how to manage %GlobalCharacterStream representing JSONS.

Thank you for reading this question, thank you for your help, and thank you for your time and attention.

Specifically, in a certain Process, we were querying 2 Operations, whose response we were converting to a Property called "informesAutorizadosRangoFechas" (reportsAuthorizedInRangeDates) which is %GlobalCharacterStream whose content is a JSON with the same structure.

Rule logic

In an HL7 Business rule I am trying to block ONLY ORM messages that have a PV1:3.4 of 105 or 205 and a OBR:4 value of EP22 or CATH01.

I created the logic below but it appears to be evaluating the two fields independently instead of combined?

Here is what I had.
