Hi Anton,
Thanks for helps. I have found the answer to my last question (how to make two
instances of a Client to talk to two different Daemons), answer is:
· No coding change is required in daemon. I am running two daemons, my
commands are:
> openhpid -n -c /etc/openhpi/openhpi.conf -p 4743 -f pid1
> openhpid -n -c /etc/openhpi/openhpi.conf -p 4744 -f pid2
· export OPENHPICLIENT_CONF=/etc/openhpi/openhpiclient.conf . My file
looks like as shown below:
> cat / etc/openhpi/openhpiclient.conf
### OpenHPI client library configuration example file ###
#######
## Section: Domains
## Since each openhpi daemon instance manages a hpi domain,
# each domain declaration specifies domain number, hpi daemon host
and hpi daemon port.
#
## Example domain declarations:
domain 1 {
host = "localhost6" # String value. Double quotes required.
port = 4743 # Interger value
}
domain 2 {
host = "localhost6" # String value. Double quotes required.
port = 4744 # Interger value
}
· To which Daemon client will talk is configured in openhpiclient.conf
file. E.g.
>./hpievents –D 1 (This instance talks to Daemon 1 i.e. port=4743)
>./hpievents –D 2 (This instance talks to Daemon 2 i.e. port=4744)

Subject: RE: [Openhpi-devel] Why not able to run more than one daemon (using
different port) in same m/c?
Just to clarify I modified code for run daemons with user passed domain Id
value. I am running daemon1 with domain_Id=100 and daemon2 with domain_id=200.
My purpose is to run two daemon and two instances of a client to talk to each
of them- is there any other way than implementing domain Id for this.

Hi Anton,
Thanks, I am able to start-up more than one daemons (currently I am running two
of them, though both of them are running with DomainId=0). I as well want to
run two client instances each of them to talk to each daemon instance- probably
to do this my daemons should have different domain Id. To implement this I
added below code:
typedef struct {
SaHpiDomainIdT domain_id;
} UserData_t;
In Method main() of openhpid.cpp:
---------------------------------
UserData_t *user_data = new UserData_t;
//User Data field is populated same way as <port no.> is populated in
main from command line argument
// create the thread pool
thrdpool = g_thread_pool_new(service_thread, (gpointer)user_data,
max_threads, FALSE, NULL);
Modified service_thread and HandleMsg to pass user_data. In HandleMsg method
changed code to run daemon with user passed daemonId value:
ret = saHpiSessionOpen(
((UserData_t*)user_data)->domain_id, &session_id, securityparams );
I used below commands to run both the daemons:
[root@rmtestvm1 preeti]# openhpid -n -d 100 -c /etc/openhpi/openhpi.conf -p
4743 -f pid1
[root@rmtestvm1 preeti]# openhpid -n -d 200 -c /etc/openhpi/openhpi.conf -p
4744 -f pid2
I am trying to run client “hpievent –D 100”, I am getting error shown below:
[root@rmtestvm1 clients]# ./hpievents -D 100
/root/preeti/openhpi-2.15.1/clients/.libs/lt-hpievents (rev 7189) - This
program came with OpenHPI 2.15.1
SAF HPI Version B.03.02
************** timeout:[0] 100****************
saHpiSessionOpen: INVALID_DOMAIN
[root@rmtestvm1 clients]#
./hpievents -D 200 is also giving same error.

Preeti
