IBM Mainframe Forum

Hi Folks,

I'm very new to IBM Z/os and mainframes but I have a lot of unix experience, not that it is relevant.

This is my first post here.. I'm creating this under the emulator forum because this is an emulated setup, so please forgive me if this is the wrong location for this topic.

My scenario: I want to run a java7 app on Z/os 1.10 under hercules

What works: Z/os works, connectivity is fine over the tun interface.

The problem: The volumes I have don't have enough space for me to download and install the java7 pax.z

My approach so far :

I've used dasdinit to create a large volume set outside hercules...



I've configured hercules to allocates them to OAB5 3390 device..



in ISPF / ICKDSF I see the volume, but I can't seem to issue an INSTALL against it



So, this isn't working.. The obvious question is what else should I try ?

Other approaches that also failed.. :

I've also tried copying an existing CCKD but it conflicted on volser and I can't work out how to change a volser from outside hercules.

I'd be grateful for any help or guidance here.

use ickdsf to initialize the newly created volume

Hi Enrico,

I've tried this.. via the ISMF ICKDSF panel

All the docs seem to state that INIT is the wrong command for 3390 devices, and that I should use the INSTALL command





which also logged the job on the other terminal



But the device still shows up with the "??????" seen previously in my first post.

Even if you use INSTALL, the manual Device Support Facilities (ICKDSF) User's Guide and Reference states you STILL have to use INIT:

Warning

After the install process is complete, you must initialize the volume for use in your operating environment. To initialize your volume, use the:

INIT command for MVS or VSE
CPVOLUME command for VM
AIXVOL command for AIX

Try something like

Select all

//SYSPRINT DD   SYSOUT=*    
//SYSIN    DD   *            
  INIT UNIT(0AB5) NVFY VOLID(JAVA17) VTOC(000,01,059)

OK. I've run this after the install command.

I get this back, in red.

the simple return code does not tell anything.
post the FULL ickdsf sysout

another thing I've noticed..

on this JAVA17.CCKD file I get the following error back if I dasdls it.

even if I recreate it, I get that error.

F4DSCB record not found

if I rerun the dasdls after ICKDSF INSTALL/ ICKDSF INIT, it still claims there is no record.

Hi Enrico,

Where can I find the sysout from the job (or any job, for that matter..) ?
