Look at the documentation for those environment variables particularly
the last 2.

EPICS_CA_AUTO_ADDR_LIST=YES
EPICS_CA_REPEATER_PORT=5064
EPICS_CA_SERVER_PORT=5065

and set them at different values BEFORE you start your ioc programs.

EPICS_CA_AUTO_ADDR_LIST=YES
EPICS_CA_REPEATER_PORT=5066
EPICS_CA_SERVER_PORT=5067

I'm not sure if that's what he wants:
the channels of this second IOC would be provided under a differend CA port number.
To access channels from two IOCs with different CA port numbers, you need to provide host and port number in the EPICS_CA_ADDR_LIST.
Each application should be able to access channels of every IOC, shouldn't it?
If that's the case, the suggestion is not feasible.

Hello..
Excuse me, I have a question about using muti IOC
I ran an IOC on Linux computer..
System informaion
EPICS IOC OS : Radhat Linux9.0
EPICS Extensions OS : Radhat Linux9.0
EPICS base : Release R3.14.8.2 (IOC, Extensions)
We wanna run more one IOC on one Linux...
I tried to run two st.cmd files..
the error meassage is like below...
cas warning : configure TCP port wwas unavailable
cas warning : using dynamicaly assigned TCP port 36885
cas warning : but now two or more severs share the same UDP port
cas warning : Depending on your IP kernel this server may not be
cas warning : reachable with UDP unicast (a host's IP in EPICS_CA_ADDR_LIST)
I have alreadly read channel access reference manual and found tech tech content..
However, I didn't configure to solve this error...
How I do configure to solve our problem? We must run multi(two, three or four) IOCs on a Linux computer.
Could you say to me a comment or a method?
Thank you very much, Happy New Year!
from Hyun Mi, Choi
