Request for Auto-Start Configuration Steps for Cache 2018 on AIX

Hi Team,

We are currently running InterSystems Caché 2018 on an IBM AIX server and would like to configure the Cache instance to start automatically when the server boots or is rebooted.

Could you please provide the recommended steps or any official scripts/guidelines to enable auto-start for the Cache instance (QA2018) on AIX?

Additionally, if there are any best practices or prerequisites (such as filesystem mount options, service dependencies, or startup order) that we should consider, please share those as well.

Thanks,
Ganesh

What does S $ZT="^%ETSDK" mean in MUMPS / InterSystems ObjectScript?

Hi all,

I'm reviewing an older Cache routine and came across this line of code: from file ^ZDBKCRON

S $ZT="^%ETSDK"

Error trap

/home/oper/script/cache_db_backup -t        # Daily CacheDB Backup

 produced the following output:

 <NOROUTINE> *%ETSDK
<ERRTRAP>

-----------

From what I understand, this is setting up an error trap, but I'm not entirely clear on how it works, especially in modern InterSystems IRIS environments.

Could someone please help explain:

  1. What exactly does this line do?
  2. Is %ETSDK a standard system routine? I can't find it in our environment.
