Message appears in Console Terminal

[rogerb]

Good afternoon.
I've been offered the possibility of having access to a mainframe only for learning purposes.
To save power the mainframe is powered down sometimes.
Recently, when the IPL (Initial Program Load) is made, a message appears in Red color in the console terminal.

Code: Select all

*22.50.35 STC00029 *IEF882E CSQ7MSTR CSQ7MSTR IS WAITING FOR A REPLY TO
* IEF238D

I believe that these messages showing in Red color are important messages, and this may be an error, but I don't know what this mean and how to solve this problem.

Thank you,
Roger

The message means that a previous IEF238D message was displayed on the console (after an IEF244I message). The IEF238D requires a reply since it indicates that the system cannot complete allocation of one (or more) device(s) -- see the message text in the manual for the possible reasons for this. The IEF882E message indicates that no reply has been received. If using SDSF, keying SR on the command line will take you to the reply messages; otherwise, issuing console command D R,L will show you them. The IEF882E will continue to appear until a reply has been made to the IEF238D message.

but I don't know what this mean

Google is your friend: both IEF238D and IEF882E.

Hello,
Thank you for your answers.
I write D R,L in th console terminal and I see the following:

Code: Select all

IEE112I 23.31.36 PENDING REQUESTS    FRAME  1     F      E   SYS=ADCD

                                 FOR VOLUME PRIVAT-   1              
IEE612I CN=L700     DEVNUM=0700 SYS=ADCD

I've looked in the IBM pages for IEF238D and IEF882E.
Those pages have technical information that is difficult to understand by a newbie like me.

Thank you,
Roger

The IEF877E message tells you that one unit is needed for CSQ7MSTR job DD name SYS00010. Look at the JCl or the job to determine the characteristics of that DD name and figure out a replacement volume serial / unit for it.

[rogerb]

I typed TSO SDSF. I typed ST and the I searched 'S CSQ7MSTR'.
I opened the job CSQ7MSTR and I showed the JESYSMSG.
I see the following:

Code: Select all

IEF506I CSQ7MSTR CSQ7MSTR SYS00009 - NO STORAGE VOLUMES. 'VOLUME=PRIVATE' ASSUMED

IKJ56221I DATA SET CSQARC1.CSQ7.B0000021 NOT ALLOCATED, VOLUME NOT AVAILABLE+

IKJ56221I VOLUME  NECESSARY TO SATISFY YOUR REQUEST NOT ON SYSTEM, AND CANNOT BE MOUNTED

Thank you,
Roger

[Robert Sample]

The job needs a different volume for the data set. Unless you give it one, you'll need to reply to the message with CANCEL to kill the CSQ7MSTR job.

[rogerb]

Thank you for your answers.
When I search for a certain dataset, by using option 3.4 Dslist in ISPF, there are at least 2 volumes.
The volume ZARES1 has got System Librairies like SYS1.PARMLIB.
The volume ZASYS1 has got my Private JCL Librairies, Maps/Mapsets and COBOL programs.

Which one should I use or should I CANCEL the job ?
If I cancel the job I will afect the system or the performance of the mainframe ?

Thank you,
Roger

horse manure ...

how much power do You expect to save by turning off Your emulated mainframe ??

[rogerb]

Good afternoon Mr. Enrico-sorichetti.
I mentioned that information because I was trying to provide all the relevant information about this situation.
I was trying to contextualize the problem.
The fact is that I have a problem and I'm trying to solve it and I asked for help.

Thank you,
Roger
