Using DTrace on OmniOS is not straightforward:
$ pfexec dtrace -n 'syscall:::'
dtrace: failed to initialize dtrace: DTrace device not available on system
Need to install both dtrace and dtrace/providers packages:
$ pfexec pkg install dtrace dtrace/providers
Now the DTrace module is loaded:
$ modinfo | grep dtrace
5 fffffffff8243000 1af28 280 1 dtrace (Dynamic Tracing)
Then it will work!
P.S., Thanks for Andy Fiddaman‘s help!
I followed Building OmniOS to build OmniOS, but met following errors:
$ pfexec /opt/ooce/bin/omni build_world
......
./buildctl: fork: Not enough space
../lib/functions.sh: line 627: wait_for: No record of process 22984
../lib/functions.sh: fork: Not enough space
Waiting for illumos build...
......
The reason is the virtual machine which I used has only ~1.5G memory, and it is not enough. Increase the memory to 4G, then it is OK to build.
Clone OpenSSL and create a build directory:
# git clone https://github.com/openssl/openssl.git
# cd openssl
# mkdir build
# cd build
List the supported build platforms of openssl:
# ../Configure LIST
BS2000-OSD
BSD-generic32
BSD-generic64
......
Because there is no illumos option, use Solaris instead. At the same time, I want to build in debug mode:
# ../Configure solaris64-x86_64-gcc --debug
# make
# make test
That’s all!
Following document to install OmniOS is quite straightforward. I use r151030 version and pick Solaris 11 during selecting Operating Systems on VirtualBox. To use root login through SSH, I need to do following changes:
(1) Set PermitRootLogin‘s value to yes in /etc/ssh/sshd_config file;
(2) Restart SSH service:
# svcadm restart ssh
A fresh OmniOS is born:
Update:
When installing r151032, I found selecing Oracle Solaris 10 10/09 and later (64-bit) can work.
