My Review - before being approved by OEX admins

  • This is a really excellent example on
  • How to publish in OEX
    • a clear to understand description of the target
    • a clean-to-install IPM package
    • a Docker setup easy to follow without any dirty tricks undercover
    • a fast and effective build and install that was tested in practice
    • so you can keep your working environment free of polluting code fragments
    • and a detailed understandable description of how to handle it
  • Big THANKS to @Kurro Lopez

  • Namespace %SYS
  • class SYS.Process is your friend
  • SELECT * FROM SYS.PROCESS
  • in your case :  
    select CurrentDevice from SYS.Process group by CurrentDevice
    CurrentDevice

Once upon a time ...

  • there was an operating system named VMS
  • running on computers named VAX and ALPHA
  • The syntax to access a file was  drive:[directory] 
  • it's the same structure used by RSX-11/M, RSX-11/D, RSX-11/S on PDP-11 processors

So on drive DUA1  you refer to director TEST3

Therefore it's good practice to start with

Kill ^SPOOL($J) Open 2:$J Use 2 .....
as we did in 1978

my private hack for this situation:

ClassMethod MyMethodPost() As %Status
{
    $$$LOGINFO("JobId: "_$JOB)
    kill ^%kurro
    set ^%kurro(0)=$JOB
    for  {hang 20 break    quit:$get(^%kurro) }
#; just hang around until ^%kurro =1
    ..... 
    Quit $$$OK
}

You can map PACKAGE [aka. SQL Schema] to another Namespasce (not a single table)
e.g. Bna.Utils to namespace %ALL or just to a specific namespace
so you have Table and Class  (= the code) available.

If you want to share also DATA  you need to map also  the related Global

I met some issues in the past, where I miss any idea of how to check

  • verification of %variables or variables in global scope
  • variables set as 3rd parameter in $QUERY() or $ORDER() -  should be easier to detect.
  • not sure if variables passed ByRef or Output are fixed meanwhile

$storage refers to the partition which holds only pointers into global buffers.
while the content of the global goes only to global buffers and
consumes no permanent space in your partition.

  1. find the expected format in test
  2. where do get the date from ?
    if it's from IRIS functions $ZDATE() or $ZDATEH() convert it in the required format
Robert Cemper · Jan 23, 2024 go to post

"TO_DATE('12/15/2023','MM/DD/YYYY')"  is an SQL function call not a value
could you try straight ODBC format "2023-12-15"  ?

Converting and using $H date format might be a different option

eventually terminal in *UX may end just with $c(10)
could you try to append some blank + semicolon ?

:alias enablebi do EnableDeepSee^%SYS.cspServer("/csp/"_$zcvt($namespace,"L")) ;

You seem to lose the last character

I agree with @Brett Saviano:
$$$  ...refers to some #define ...  and is a compiler directive

I tried:

USER>:alias wi write "/csp/"_$zcvt($namespace,"L")
 
USER>:wi
write "/csp/"_$zcvt($namespace,"L")
/csp/user
USER>:alias wi1 write "/csp/"_$$$LOWER($namespace)
 
USER>:wi1
write "/csp/"_$$$LOWER($namespace)
 
WRITE "/csp/"_$$$LOWER($namespace)

  • my personal preference goes to %GSIZE.
    The best match between CONSUMED and ALLOCATED size is found
    if your Global is "filled" total sequentially by a $Q() loop.
    And even then with a big string, you may force unexpected block splits.
    The situation changes if you fill your globals by subscript levels.
    This may cause a cascade of block splits and result  in rater unattractive packing percentages
     
  • ALLOCATED Size by Subscript might be of interest for an individual Subscript.
    Though adding them up doesn't reflect the total size
    It's like cutting a cake to 12 people and then counting the heads that had some cake.
     
  • to reduce the space consumption of your globals I rather suggest to  use
    ##Class(%GlobalEdit).GloabelCompact()  to eliminate the effects of random inserts
    and growth inside a global tree.
