There are not such methods, we only have function which converts delimited string to $listbuild format and back. And you can do it in this way, without any looping, but only if you already know how many items you have.

USER>set string="a,b,c,d,e,f"

USER>set list=$lfs(string,",")

USER>zw list
list=$lb("a","b","c","d","e","f")

USER>set $lb(array(0),array(1),array(2),array(3),array(4),array(5))=list

USER>zw array
array(0)="a"
array(1)="b"
array(2)="c"
array(3)="d"
array(4)="e"
array(5)="f"

What do you want to fix? Locked access or change security level?

Mostly when you run some server application inside a container, it means that no needs any changes of settings, while this container is up because all that changes may disappear after restart container form a new image.

I would recommend changing security level in the installation process. You can do it with some environment variables described in the documentation. Just add this lines in the Dockerfile before cinstall_silent command

ENV ISC_PACKAGE_INITIAL_SECURITY="Locked Down" \
    ISC_PACKAGE_USER_PASSWORD="secretpassword"

And your installation will be secured.

Read more about initial security settings in the documentation.

Sure, leading zero, so, fixed code.

set hashHex="" for i=1:1:$l(hash) set hashHex=hashHex_$translate($justify($zhex($a(hash,i)),2)," ","0")

The difference only in output format. InterSystems returns just string of bytes, while online generator returns hex codes for that bytes, which is much better for reading by human. So,  you may quickly check it with command zzdump. And you may notice, that zzdump shows the same hash you got from online generator.

USER>set hash=$system.Encryption.SHAHash(512,"test")

USER>zzdump hash

And this simple line of code, may help you to convert this hash to hex hash.

USER>set hashHex="" for i=1:1:$l(hash) set hashHex=hashHex_$zhex($a(hash,i))

USER>write hashHex

USER>write $zconvert(hashHex,"L")

In my experience such behavior I saw when we had so many writes to the disk, and write daemon queue only grown up.

In first I would launch mgstat tool from InterSystems. But it should be started before the freezing system, and for quite long time, with at least 5 seconds interval, better if it would be 1 second. Then you should look at some columns such as WDphase, PhyWrs, WDQsz.

What you should look for. 

• WDphase -  should not be all the time in the 8th phase.
• WDQsz - from time to time should fall to zero
• PhyWrs - may help to calculate a "real" speed of writing to the disk. And compare with expected speed.
• WDPass - time to time should be increased, if WD still at the same cycle so long time, it may cause a freezing system.

Thanks, and thanks for your articles hope to see next article soon.

Plase add some more details, what do you mean by slowly?

Do you work remotely? Is it still slowly if connect locally on the server?

Well, there are some different reasons to do it:

• optimization network traffic for readers. You should remember, that you wrote the public article for people all around the world, with different quality of their network connection. Some people may even disable images for loading.
• in slow internet connection, you may see empty spaces for your images, while it will be loaded.
• it is a bit difficult to recognize your terminal images due to the white background, the same as for page. If you put it as a formatted text, it will have the different background.

I would recommend to use a bit modern way

set rs=##class(%Routine).RoutineListFunc("ABC*.int")
while rs.%Next() {
  write !,rs.Name
}

Tani, please change all terminal samples and samples of code from pictures to plain formatted text.
