System, Partition, and Processor pool information all in one place

qlzarcapi for system, partition, server pool information

I am the first admit I do not know everything about IBM i as, in my opinion, there is just too much to know. Therefore, I am always grateful when people send me things they have found as there are many times they are new to me too. I have Laurent Gomes to thank for bringing to my attention the API QLZARCAPI.

I find it interesting that I cannot find any mention of it IBM's KnowledgeCenter, and only a passing reference in the documentation for the QMGTOOLS. What this API does is to display the system, partition, and processor pool information for the current IBM i partition.

I have found the best place to display this information is in the QCMD screen.

  CALL QCMD

At the QCMD screen I type:

  CALL QSYS/QLZARCAPI

And the following information is displayed:

                              Command Entry                         MY_SYS

 Previous commands and messages:

Type command, press Enter.
===>                                                                     

Note:  I have changed some information for security reasons.

Lots of interesting stuff which will prove invaluable to have in one place if you need to provide system information to a helpdesk or something similar.

I just want to say "Merci" to Laurent. I just love that there is so much stuff in IBM i, and there is always something new to discover.

 

This article was written for IBM i 7.3, and should work for earlier releases too.

  1. Good tip. That's a whole lot more information than trying to piece things together using GO SERVICE option 6, and DSPDTAARA QSS1MRI)
    - Serial Number: (DSPSYSVAL QSRLNBR)
    - Model Number: (DSPSYSVAL QMODEL)
    - Processor Feature Code: (DSPSYSVAL QPRCFEAT)

  2. I think a post on what is actually a partition/pool/and rest would be an insight on this topic for developers like me when we display this API.
