Re: SWAPGEN + RHEL 7

[Alan Ackerman]

We have two VDISKs and one real disk for swap area for each zLinux server. We 
run SWAPGEN on all of them every time we boot CMS, but as you point out, it 
only has to be done once for the real disk.

The VDISK are 10% and 5% of memory size (up to VDISK maximum. The real disk is 
800 cyl.

I'm not sure why we did that. (Other recommendations are welcome.) I remember 
IBM suggested swap = 10-15% of memory, and to use VDISK. I don't remember where 
the real disk came from, though.

The theory is we track when the third (real) disk is used. But we never set 
that up. (I guess I'd better ask Velocity Software how to alert for that.)

You should be able to download the SRPM using zypper.

zypper in -d -t srcpackage openCryptoki

Will download the source package and leave it in /var/cache/zypp/packages/...

​Well, I got a tgz file for 3.5 by doing:

curl
http://iweb.dl.sourceforge.net/project/opencryptoki/opencryptoki/3.5/opencryptoki-3.5.tgz
>|opencryptoki-3.5.tgz

after unwinding the tar, I found 3 different "def.h" files:
./usr/lib/pkcs11/tpm_stdll/defs.h
./usr/lib/pkcs11/cca_stdll/defs.h
./usr/lib/pkcs11/common/defs.h

I would guess that you need the one in the "common" directory (the last in the 
list above).​

If you're using real DASD, you don't need to keep re-writing swap signatures 
after the first time.  That's only necessary with TDISKs or VDISKs where you're 
not sure if it's "new" or not.

Ah, ok.  Well, hopefully swap is rarely used so efficient might not matter much 
with that here.

Personally, I suggest abandoning SWAPGEN and just formatting/reserving the 
MDISK via CMS, then doing a mkswap /dev/disk/by-path/ccw-0.0.0xxx-part1 in your 
boot.local (or equivalent).  This assumes that you are consistent in your

keeping some external routine up to date with changes in swap handling within a 
Linux guest.

The same here. The problem started after upgrading RHEL 7.1 to 7.2. The error 
goes away with a clean boot, wherein the z/VM virtual machine is logged off,

Re: EXTERNAL: SWAPGEN + RHEL 7

[Hodge, Robert L]

The same here. The problem started after upgrading RHEL 7.1 to 7.2. The error 
goes away with a clean boot, wherein the z/VM virtual machine is logged off, 
then XAUTOLOGged. The error always occurs on a reboot.

Re: SWAPGEN + RHEL 7

[Cohen, Sam]

Alan,

Personally, I suggest abandoning SWAPGEN and just formatting/reserving the 
MDISK via CMS, then doing a mkswap /dev/disk/by-path/ccw-0.0.0xxx-part1 in your 
boot.local (or equivalent).  This assumes that you are consistent in your 
assignment of the swap disk address.  Then you don't have to worry about 
keeping some external routine up to date with changes in swap handling within a 
Linux guest. 

Religious argumentsstart your engines!

Thanks,

It looks like the developers intended for it to be used only for building the 
package, not for "external" use.  It's only referenced in the Makefiles like 
this:
noinst_HEADERS = defs.h

So, you might want to build the sample you found inside the unpacked source 
tree.  I would recommend using the same version of the source as you currently 
have installed on your system.

​Well, I got a tgz file for 3.5 by doing:

curl
http://iweb.dl.sourceforge.net/project/opencryptoki/opencryptoki/3.5/opencryptoki-3.5.tgz
>|opencryptoki-3.5.tgz

after unwinding the tar, I found 3 different "def.h" files:
./usr/lib/pkcs11/tpm_stdll/defs.h
./usr/lib/pkcs11/cca_stdll/defs.h
./usr/lib/pkcs11/common/defs.h

I would guess that you need the one in the "common" directory (the last in
the list above).​

Anyone know where "defs.h" comes from?

Doesn't seem to come with opencryptoki-devel package.
