Pinned topic Loosing the zPDT/1090 Master Console

‏2011-01-13T22:30:33Z |
Hi Friends, I have been configuring RDzUT version 7.6.2 with zPDT and all has been going very well with one erratic problem. After I made the Configuration Guide changes for CICS pages 21 and 33 I have been occasional loosing the master console with the following messages displayed in Linux:

-bash-3.2$ OPRMSG: *IEA247I USING IEASYS4K FOR z/OS 01.11.00 HBB7760
OPRMSG: Beep!
OPRMSG: ISG313I SYSTEM IS INITIALIZING IN GRS NONE MODE. RING OR STAR CONFIGURATION KEYWORDS IN GRSCNF00 ARE IGNORED.
OPRMSG: IEA598I TIME ZONE = W.06.00.00
OPRMSG: IXC470I SYSTEM ADCD EFFECTIVE VALUES: INTERVAL=165 OPNOTIFY=168
OPRMSG: DEFAULT USER INTERVAL: 165
OPRMSG: DERIVED SPIN INTERVAL: 165
OPRMSG: DEFAULT USER OPNOTIFY: + 3
OPRMSG: COMPUTED FOR: XCF INITIALIZATION
OPRMSG: IXC413I MULTISYSTEM SYSPLEX CONFIGURATION PREVENTED BY SYSTEM COMPONENT
OPRMSG: ISG150I GRS=NONE IS NOT SUPPORTED WHEN RUNNING IN A MULTISYSTEM SYSPLEX.
OPRMSG: IXC418I SYSTEM ADCD IS NOW ACTIVE IN SYSPLEX ADCDPL
OPRMSG: CNZ9013I CONSOLE SERVICES RUNNING IN SHARED MODE.
OPRMSG: IEE712I SET CNGRP PROCESSING COMPLETE
OPRMSG: IEA549I SYSTEM CONSOLE FUNCTIONS AVAILABLE
OPRMSG: SYSTEM CONSOLE NAME ASSIGNED HWCI
OPRMSG: CEE3739I LANGUAGE ENVIRONMENT INITIALIZATION COMPLETE
OPRMSG: IEE389I MVS COMMAND PROCESSING AVAILABLE

Everything else runs fine, similar messages plus the IPL messages appear on the LOG, and again it happens on and off.

Any ideas? Thanks

    Hi Joseph,

    I actually saw something similar to this while I was doing my initial setup. Basically I had run ./runzpdt, the console came up and started fine, and I was able to remote terminal into the box without issue. The next day the command console was gone on my linux box, but the system z still ran fine. With SDSF I shut things down the best I knew how, and then ran an awsstop. Next time up it worked fine and has for the last 5 months.

    My theory was that it was SUSE Linux that closed the window. A number of helpful updates had gone into half installed mode for me and were requesting a linux restart. My guess is that something tried to close all running applications and the terminal emulator program was a victim.

    Question for those smarter than me. Is there an AWSXXXX command we can run to bring the master console back up?

    Thanks Aaron, opening and closing the Putty connection to the Linux box has caused it to behave correctly on occasion. Hopefully someone has something more to say. Again tahnk you very much.

    In the event the mstcon is lost, attached are two options one can use for recovering the mstcon. It may be a good practice to enable two x3270 consoles. This will enable you to recover the mstcon via SYSLOG using option one below :

    #1 : The following series of commands can be entered from an alternate TSO console :

    /v 700,offline
    /v 700,online
    /v 700,console

    ( The / is required when entering commands via the SYSLOG )

    #2 : The mstcon can also be recovered by entering the following oprmsg commands on your Linux hardware console.
    The oprmsg command is documented in the RedBook : IBM System z Personal Development Tool: Volume 1 Introduction and Reference SG24-7721-02,

    $ oprmsg 'v cn(*),activate' (activate the "hardware console" for commands)
    $ oprmsg 'v 700,offline'
    $ oprmsg 'v 700,offline,force' (if the simple vary offline fails)
    $ oprmsg 'v 700,online,uncond'
    $ oprmsg 'v 700,console'
    $ oprmsg 'v cn(*),deactivate' (optional)

    Thanks mingoCid, I actually found and figured the oprmsg Vary Console commands from Linux (and from TSO) to reoover the Master Console back to x3270 700 window.

    I have been having this issue on and off for some time (since I made the CICS changes noted in the RDZ UT: Configuration Guide (pages 21, 22, and 33).

    I have tried rebooting Linux, starting zPDT clean, and increasing the delay interval before IPLing zOS does not solve the problem. It's just pain erratic.

    So I am really interested in why this is happening but am very glad someone out the is listening and I thank you.

    Have you checked to see if you might be taking MIH hits on your terminal device? You should be able to see these clearly in your Syslog. How many cores do you have on your machine vs. how many cores are defined in your devmap? If you overcommit your cpu cores, sometimes this can cause problems also. If you could post your devmap here, we may be able to see something there.

    Thanks RDzJohn I will up the MIH number will have to for some of the Network changes I aam about to make anyway.

    The devmap specifies one CP but the machine actually has 3 cores if I remember well.
    memory 4096m
    processors 1

    The platfrom is Thinkpad W510 300 GB hard drive 6GB of memory, 8 cpus 1199MHz 4 cores 8192 kb of cache.
