Hi Alex,
Thanks a lot for the help. I try to run OpenSAF in a single node
environment.
It turned out that the failure of message sample program is due to
nodes.cfg. Initially, I created a two-node configuration with
"immxml-clustersize -s 2" with the assumption that two controllers are
required. After re-creating nodes.cfg with one controller using
"immxml-clustersize -s 1", the sample program works.
Although the root cause may be identified, I still don't know the
reason/mechanism behind the failure. In my opinion, a two-controller
configuration file should be allowed. The topology may have two controllers but
my app just uses one.

Hi Feng,
How many nodes are you running? Just 1 controller?
Look in /var/log/messages for output from msgd and msgnd. These implement
the MSG subsystem. Maybe there is something wrong with how they started up.

Subject: Errors in running OpenSAF message sample
Hi,
Thanks a lot to Anders' suggestion. After downgrading from Python 3 to Python
2.7, the errors in running immxml-configure were resolved!
I was able to start OpenSAF related demos and compile sample programs. The
first OpenSAF sample program I ran is msg_demo under
~/local/share/opensaf/samples/mqsv. The sample was run in a single-node Ubuntu
VM. However, I encountered error code 2 from saMsgInitialize. I checked the
source code in ~/src/msg/agent/mqa_api.cc, it seems that error code 2 maps to
SA_AIS_ERR_LIBRARY. There are may occurrences of it. I am stuck at this step.
Any help will be highly appreciated!
In addition, I have two additional questions:
1. Is there a timer service provided by OpenSAF?
2. How to turn on internal tracing when running OpenSAF sample programs?
The output from ./amf-state, error messages and opensaf demos are attached
at the end of the email for reference. Thanks.

Subject: Re: Errors in running immxml-configure with OpenSaf 5.3 in a Ubuntu VM
Just a wild guess: maybe your Linux distribution installs Python version 3 as
default? We haven't fully converted our Python code to be compatible with
version 3 yet (it ought to be done, though). Could you run 'python --version'
to check your default version. If it is version 3, you probably need to install
version 2 and use it to run the OpenSAF Python code.
OpenSAF supports running in virtual machines.

Hi Dheeraj, Gary and Anders,
Thanks a lot for the quick response! With your help, I was able to solve
the original issue of locating the share libraries. The current issue I am
facing now is with immxml-configure, which failed in File "./immxml-merge",
line 370, in save_result
self.imm_content_element.toxml(encoding).replace("/>", ">") + "\n"). As a
result, IMMD can't be started. My debug procedure and detailed error messages
are attached at the end for your reference. I am stuck at this step. Any help
will be highly appreciated!
Let me provide some background information about my current effort so
that you can better understand my situation:
1. I am trying to use opensaf for core middleware services like messaging
(IPC), log, timer, etc.. The target environment is a single-node multicore
(ARM) Linux embedded system. If opensaf works in a single-node environment, we
may extend to a cluster environment in the future.
1. I created a virtual machine using VMWare on a X86 Dell PC with ubuntu
Linux and installed the latest opensaf tarball (OpenSAF package
opensaf-5.18.02.tar.gz in a Ubuntu Linux VM (Linux version 4.4.0-116-generic
(buildd@lgw01-amd64-021) (gcc version 5.4.0 20160609 (Ubuntu
5.4.0-6ubuntu1~16.04.9));
1. As part of proof of concept, my goal is to start opensaf related daemons
in such single-node VM environment and run several sample programs.
1. The installation/configuration procedure I follow is exactly as Anders
suggested:
https://sourceforge.net/p/opensaf/wiki/OpenSAF%20as%20an%20application/. I did
not try any extra advanced configuration yet. Thus, I have NOT changed
nid.conf. The underlying transport is still TCP. The OPENSAF_GROUP/USER are
still "opensaf". The node_type is "controller" and the node_name is
"feng-opensaf-2".
By the way, from the above website, I saw a statement like "Note no sudo
or virtualization!". Does it mean that OpenSAF can't be run in a VM
environment? Thanks again for your help!
Feng

Subject: RE: Errors in running OpenSaf 5.3 in a Ubuntu VM
Hi Feng,
Please follow the file "00-README.conf" in the Opensaf source code and
configure.
Let me know if you find any difficulties.
You can just try by following the below steps:
1- Modify the file /etc/opensaf/nid.conf
export OPENSAF_MANAGE_TIPC="yes"
TIPC_ETH_IF=<network interface>
TIPC_NET_ID=<tipc net_id value> (ex- 1234)
# The below variables have to be changed to "root"
# if user has built OpenSAF to run as root
export OPENSAF_GROUP=root
export OPENSAF_USER=root
2- edit file "/etc/opensaf/node_name" with node name.
3- edit file "/etc/opensaf/node_type" as controller or Payload.
How many controllers and payloads in your cluster?
4- cd /usr/share/opensaf/immxml/
Generate a config file (nodes.cfg) for a 5 node cluster:
$ ./immxml-clustersize -s 2 -p 3 (for 2 controller and 3 Payloads)
Edit nodes.cfg
The third column in nodes.cfg should be edited to match the short form of
the
hostname (as shown by 'hostname -s') for each host.
$ ./immxml-configure
Copy the generated imm.xml file to the standard OpenSAF configuration directory.
For eg:
$ cp imm.xml.20100217_2201 /etc/opensaf/imm.xml
Then start opensafd.

Subject: [users] Errors in running OpenSaf 5.3 in a Ubuntu VM
Hi,
I am new in using OpenSAF. I encountered an error in running the latest
OpenSaf software in a Ubuntu Linux VM. I would appreciate if somebody can
provide some hint on this issue in specific and some references in running
OpenSAF in general. Thanks a lot in advance!
1. Procedures and errors encountered
* Download the latest OpenSAF package opensaf-5.18.02.tar.gz in a Ubuntu
Linux VM (Linux version 4.4.0-116-generic (buildd@lgw01-amd64-021) (gcc version
5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9));
* Use "./configure -enable-tipc", "make" and "make install" to install
the OpenSAF;
* Use "/etc/init.d/opensafd start"
* Errors (output from "journalctl -xe")

1. I checked /usr/local/lib and I found libopensaf_core.so.0 by "ls -l
/usr/local/lib"

............
1. Then I modified my $LD_LIBRARY_PATH to include "/usr/local/lib" by adding
it to the .bashrc file and did "source ./bashrc"
root@opensaf-2:/home/xyz# echo $LD_LIBRARY_PATH /usr/local/lib
1. Rerun opensaf by using "/etc/init.d/opensafd start", the same error was
seen.
