Congrats:
I like your code example that demonstrates deep understanding of the DB concept.
 💪

From docs:

tformat = 1  >>> Express time in the form "hh:mm:ss" (24-hour clock).

W $ZTIME(338,1,)
00:05:38

W $ZTIME(338+43200,1)
12:05:38

My guess: You look for this

​​​​​​​W $tr($ZTIME(338,3),"AM")
12:05:38

set time="2023-09-28T20:35:41Z"
write $TRANSLATE(tine,"-:TZ")

20230928203541

Do you look for a kind of LOGGING ?

👍💪

iris | 08/15/24-05:47:48:778 (828) 3 [Utility.Event] Error while moving data directories

ERROR #5001: Cannot create target: /shared/durable/

You may have some file protection issue

on Windows use  $$$installdir\bin\iris.exe 

• iris stop <instance-name>
• iris start <instance-name>

for instance-name use iris list 

• a zen page definition creates a class (just like CSP)
• the runtime of this class is an INT routine.
• Anr there is hidden the truth of JS and COS  

ZENpages load a bunch of dedicated js libraries + scripts in browser for it's communication
Suggestion: create a simple ZEN page and check js libraries and scripts used. 

do HELP^%G    no blank between P and ^%G
straight Objectscript

not so much need of a SET class in ObjectScript

• every local variable array or a global allows alphanumeric subsriüpts up to size 255
• those subscripts are unique

thanks for the explanation ! 

my example as code

Using my previous reply you can do this without need of any custom object:

SAMPLES>read xml
<?xml version="1.0" encoding="UTF-8"?> <session> <session_Id>124364</session_Id> </session>
SAMPLES>set rdr=##class(%XML.Reader).%New()
SAMPLES>do rdr.OpenString(xml)
SAMPLES>zwrite 
 
%SAX=1
%SAX(1)=2
%SAX(1,0)=""
%SAX(1,1)="1" ""
%SAX(1,2)="!>A"
%SAX(1,"N","http://www.w3.org/2001/XMLSchema-instance")=1
%SAX(1,"d")=4
%SAX(1,"d",1)="session"
%SAX(1,"d",2)=" "
%SAX(1,"d",3)="session_Id"
%SAX(1,"d",4)=124364
%SAX(1,"n")=1
%SAX(1,"n",1)="http://www.w3.org/2001/XMLSchema-instance"
%SAX(1,"v")=6
rdr=<OBJECT REFERENCE>[1@%XML.Reader]
xml="<?xml version="1.0" encoding="UTF-8"?> <session> <session_Id>124364</session_Id> </session>"
SAMPLES>

edited and simpler

• if this has an XMl header  <?xml version= ...
• then ##class(%XML.Reader).OpenString(yourxmlstring) will deposit your input in the local aray %SAX()

%BuildIndices is required if the indexed values are manipulated directly in the Global.
OR if the index definition is changed in Class or By DDL
during use as Object or SQL table it is maintained automatically.

• for a NEW created index this is "work in progress" that shouldn't be used until completed.
• if it's a matter of repair  $SYSTEM.OBJ.ValidateIndices() might be more useful. see my article Fix broken index
