Impact of OREF support

There are some classes in our code base that contain Methods only (no properties). I told my colleagues that converting them into the ClassMethods should improve performance as it would eliminate unnecessary OREF support at run-time. Some of them replied that it would be microseconds, so what is the reason to bother.

Is it possible to estimate the impact of OREF support of method calls at run-time? E.g., as a % of all CPU load.

Incremental Compile Issues

First, my $ZVERSION:

Cache for OpenVMS/ALPHA V7.x (Alpha) 2010.1.6 (Build 952_2 + Adhoc 17754) 3-JAN-2018 14:32:54.07

Second, my issue:

I believe my current villain is “incremental compiling.” I was able to compare early compile output with later compile output:

Compilation started on 04/10/2019 10:46:32 with qualifiers 'cuk'
Compiling class UnitTests.Task3496 incremental compile detected
Compiling routine UnitTests.Task3496.2
Compilation finished successfully in 0.800s.

Indices Not Working

Forgive my lack of understanding, but I am working on a vendor created Cache database and the indexes specified in the classes for ODBC connections are not working. A few of them are created, but of the 50+ classes we have, only a handful of them are created when the class is compiled, yet no errors occur.

Example 1:

Hi, I am trying to transform a message to meet a third party specification, and would like to know if you can advice me on how to separate a single OBX segment into several segments based on a '.'

I would like to separate the segment where the . [marked in red] is into another OBX segment. So the next segment would be:

Hi,

I have written a procedure with the help of object scripting to export data to a csv file. There is more data than the csv limit.

Can anyone please tell me how to get the row count of csv file using object scripting, so that I can write an if condition and write to a second csv file.

Please find the code writing to the csv given below.

I'm trying to tie IRIS (2019.1) into our Concord Fax cloud-based email-to-fax workflow. We have some sites that require a fax be sent to multiple locations based upon certain data (ie Radiology and Emergency departments). Unfortunately, CC-ing does not work with Concord Fax so I need a way to send the email, change the recipient, and then send it again if certain criteria are met. Is this possible? Do I need to duplicate and rename the method, calling the second one in the MessageMap?

Here's what my code currently looks like:

Merge two lists?

Hello,

We are developing a method to take two messages which have a list of data types. It is being defined as:

Class Mensajes.Response.HistoriaClinica.ConsultaCitasResponse Extends Ens.Response [ ProcedureBlock ]
{

I want to call some Java Remote Call through Java gateway. The call code as following:

class CallRemote Extends %CSP.REST {

Method Index() as %Status {

Try

set gw = createJavaGateway()

Do callJavaMethod(gw)

do gw.%Disconnect()

Catch {

}

}

}

But Every call need connect to Java Gateway and disconnect it. But It's cost too high( about 80ms)

So, According to my Java experences, I need create some connection and put it into global static ConnectionPool

I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?

Modifying %Stream contents

I have a %Stream that I want to insert some text into the middle of. I create a new stream called pNewContentStream from the original stream, then I do a MoveTo in pNewContentStream to get to the byte position I want to insert into but when I do my Write, my pNewContentStream gets obliterated with only the text that I wrote, the original content goes away and all I'm left with is my Write text.

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are:

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

I have created a class file that I want to execute daily to gather Metrics (Message Header, Space Available, etc..) and write the data into a Cache table. Now that I have written the class I want to add it to the Task Scheduler within Ensemble to run every morning. How do I go about getting the class file created as a Task within the Task Scheduler? The Documentation isn't as clear cut for creating custom tasks as one would expect.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

USER>w ("45" < "46")
1
USER>w ("45" > "46")
0
USER>w ("V45" < "V46")
0
USER>w ("V45" > "V46")
0
USER>w ("V45" <= "V46")
1
USER>w ("V45" >= "V46")
1

I have a situation where I have a handful of classes which I need to copy to another Namespace (which uses a different RoutineDB) on the same instance, load it and compile it.

Can anyone help me come up with a command that will do this quickly and easily? Perhaps something with extended reference?

This is somewhat time sensitive so thank you in advance for your ideas!
