If  you expect to be using regular expressions frequently, it might be worth your while to write a classmethod that extends Ens.Rule.FunctionSet and wraps $MATCH or $LOCATE in something that can be called from a business rule (or DTL for that matter).

/// Custom methods for business rules and DTLs
Class User.Rule.FunctionSet Extends Ens.Rule.FunctionSet
{

/// Accepts a string <var>pString</var> and regular expression pattern <var>pPattern</var>
/// as arguments; returns 0 for no match, and a positive integer indicating the match's
/// position if there is a match.
ClassMethod REMatch(pString As %String, pPattern As %String) As %Integer
  {
              Return $LOCATE(pString,pPattern)
  }

}

You could use $MATCH instead of $LOCATE in the method above, but $MATCH() assumes the supplied pattern is begin- and end-anchored. In other words, $LOCATE("this","is") returns the positive integer 3, which for all Cache boolean purposes evaluates as true. $MATCH("this","is") returns 0 (false) since "^is$" does not match "this".

If the class you create extends Ens.Rule.FunctionSet and resides in your production's namespace, it will be selectable from the function dropdown list in both the Business Rule and DTL expression editors.

When you say you can't telnet from your machine, do you mean that you don't have a telnet client installed and/or cannot install one?

Are you connecting to the server via a local LAN connection or through a VPN? There may be port-range restrictions for non-local IP addresses in the VPN server's configuration. Even if you're not using a VPN client to connect, there may be a firewall between your location and the server's location that filters traffic based on source network and/or destination port. Finally, there may be similar rules in the Caché host's internal firewall that could impact connections from specific local networks or hosts. This would explain why an Atelier connection works but a Studio connection does not.

It's also possible that your workstation's firewall/anti-virus may be blocking outbound traffic on specific ports or port ranges. If it's so locked down that you can't install a telnet client to test with, I wouldn't be surprised if this was the case.

What's the use case for this data? What sort of system(s) will it be delivered to? Have you discussed with their vendors how this data might be digested by the downstream applications?

You could write custom methods that query the source config item's properties for those values and call them from your routing rules. However, a more supportable solution would be to implement managed alerts, which will make those properties directly accessible to you in the Ens.Alerting.NotificationRequest object that's created from the Alert Manager business process.

See Configuring Alert Management in the documentation.

If your'e sure a result set of no more than 1 row will be returned, just call the %Next() method of the Snapshot object. That'll position the cursor on the first (and, hopefully only) row.

Hi Sean,

The hive you referenced is already there in the registry; I'm assuming it was created during the installation of the Caché client tools. It's in both HKEY_CURRENT_USER\Software\InterSystems\Cache Studio\Settings\Editor and HKEY_USER\(user key value)\Software\InterSystems\Cache Studio\Settings\Editor. The Hover key wasn't present, so I added it as a REG_DWORD value of 0.

The behavior is different, but it doesn't solve the OP's problem ... the "First Record" tip still displays, but it no longer changes when you move the cursor to a class or method where it would normally populate with helpful information.

As Atelier is an Eclipse plug-in, you really need to look at it from that perspective. And given that it's really Eclipse that we're talking about, there are so many useful plug-ins for Eclipse (never mind the multiple distributions it's available supplied as) that it's not an easy answer.

I/O performance trumps CPU speed, though, so you'll get the best results with a SSD. I'd say a minimum of a dual-core CPU manufactured within the last 8 years and 4-8 GB of RAM will work satisfactorily unless you're a demon coder. I run Atelier in the JavaScript-HTML distribution of Eclipse on a dual-core-emulated, Windows 7 64bit VM under VMWare 14 on a 32GB ThinkPad T460p (quad-core, 8 threads, 2.7GHz, 2TB SSD), and am usually running 3-4 VMs at a time. Performance seems fine, but I'm not head-down pounding out ObjectScript all day long ...

I'm currently trying to get Eclipse to install on a ThinkPad T420 running Ubuntu 18.04 Desktop to see what it's like but have yet to succeed in getting it to run. I think 18.04 may not be quite ripe enough yet ;)

When Caché was installed, a group was defined for users who may stop/start/restart it (most likely cacheusr). You'll need to make the non-root user a member of that group, unless you'd prefer to use sudo as previously mentioned.

$ sudo usermod <username> -G cacheusr -a

If the user is already logged in, he/she may need to run newgrp to select cacheusr as their primary group:

$ newgrp cacheusr

The setting is overridden on a primary mirror member such that all global updates are frozen on a journal write error anyway, so the setting really doesn't matter unless you're operating  in a non-mirrored configuration. I've yet to run across a healthcare implementation of Ensemble that wasn't mirrored, but I suppose they exist somewhere. For those cases, I would enable Freeze on Error. Better late delivery than data loss.

Hi Larry,

In a code rule, you'll need to concatenate the path string with the k1 variable, as such:

do source.GetFieldStreamRaw(.stream, "PIDgrpgrp(1).ORCgrp(1).OBXgrp("_k1_").OBX:5.1")

Complex workflows that include database interaction and response handling are better suited for a Business Process / BPL, and you have complete access to the request and response objects there. You can conditionally route to as many target operations as you desire as well. Is there a reason you would prefer to do all of this through a routing rule?

It's not uncommon for mail administrators to disable group/distribution list delivery from external sources. Are you able to send mail to the distribution list via other methods from external domains?

I believe the "View Raw Contents" feature was added in relatively recent versions of Ensemble, possibly 2013+. What version is your client running?

Messages dequeued from another business host will have the IsMutable property set to false. Creating a clone of the message with the %ConstructClone() method or creating a new message object via a DTL will give you something you can update.
