Check ^%ZSTART routine. And ^%ZSTOP for shut down.

Thanks!

I see it still uses $zf(-1) in latest instead of $zf(-100). I thought $zf(-1) is unavailable now.

Is there an easier way to get value from OS call then Input redirection?

Windows also has Ver command:

USER>$Ver

Microsoft Windows [Version 10.0.17134.345]

If it's a REST/CSP so you can just write the response to the current device add at the beginning of your method:

set %response.ContentType = "html"
do ##class(%CSP.Utils).DisplayAllObjects()
return $$$OK

It would output all headers as Cache sees them.

Have you tried:

write %request.GetCgiEnv($zcvt("HTTP_MyCustomHeader", "U"))

Note that you should build bitmap indices only for properties that have less than ~6400 distinct values. Also building indices may take time. Don't forget to recompile embedded SQL and purge dynamic SQL queries.

As I'm the author of RESTForms, I'd recommend that. The advantage is that it offers not only JSON<->object transformation, but a complete CRUD REST API for your data.

All approaches you are considering can work. if you're storing everything in one database, I'd recommend RLS.

Much more important question is do you need storing everything separately or in the same place.

Advantages of separated databases/servers:

• Easy to scale
• Would work faster on a lot of cases
• Easy to delete/rebuild a chunk
• Easier security

Advantages of unified database/server:

• Cross-chunk queries are easier (For example: This venue is sold out on the dates you need. We recommend the following nearby venues)
• Simple Backup/HA strategies

You can just pass the stream directly, no need to read from it:

set parObj = {}.%FromJSON(%request.Content)

Some XSLT engines can process arbitrary javascript as code.

Achieving  FIFO with Ensemble is an interesting task.

Do you control queue population?

If so  you can send the message only if the queue is empty and process is idle.

For example create a proxy process that sends only one message at a time.

Set when? Set how often?

Check your BO message map. There's no entry for Test.SubscriberX class there.

Why is it going to intersystems-community on F5?
