Re: environmental variables

[Ralph Lange <Ralph.Lange@bessy.de>]

As long as your IOC and the machine where you run your client application are on the same network, you do not have to set any of these environment variables.

Normally you will need to set the variables only if one of the following is true:

• your IOC is on a different network than your client
• you want to "hide" local IOCs from your client (e.g. you are using a CA Gateway and your client should only see the Gateway, no other local IOCs)
• you have changed the port numbers that Channel Access uses (by setting variables on the IOC)

If you are starting a regular IOC on any machine on the local network, your client will successfully connect without any environment variable being set. This is what CA was designed for: to find all IOC data in the local network, no matter which IOC on which machine actually runs the record that your client wants to access.

Hope this helps...

I know what happened.
I added three environmental variables:
EPICS_CA_ADDR_LIST           the address I want to link
EPICS_CA_AUTO_ADDR_LIST      NO
EPICS_CA_SERVER_PORT         8888
After I deleted these variables, the CA_Get can link my own soft IOC.
But I want to link the IOC data on another PC. What is the right 
environmental variables?
Thanks!
