Preeti,
Thank Uli, not me!
My points:
o)
There is default OPENHPICLIENT_CONF path in config.h
So setting the variable is optional step (needed for path different from
default)
o)
Every OpenHPI daemon stores persistent resource id <-> entity mapping in
uid_map file.
In case of two or more OpenHPI daemon on the same system you can see file
corruption.
This leads to strange disappearance for some resources.
o)
Current OpenHPI way is the following:
1) each daemon provides domain 0
2) domain id mapping is made inside Base Library (libopenhpi.so) on client
side.
3) you can point to which daemon connect using OPENHPI_DAEMON_HOST and
OPENHPI_DAEMON_PORT env. variables
4) you can configure domain ids statically in openhpiclient.conf
5) and you can configure/tune domain ids at runtime using oHpiDomainAdd()
oHpiDomainIdById()
6) you can introduce master OpenHPI daemon who will aggregate resources
from different slave daemons in the single domain
