All,
I am using CAJ-1.1.5 and JCA-2.3.2 with Java build 1.6.0_24-b07, EPICS R3.14.9 on linux-x86
I build the "first program" shown on this page:
http://www.aps.anl.gov/bcda/jca/jca/2.1.2/tutorial.html
1a) context = CHANNEL_ACCESS_JAVA
On machines with a single NIC, if in ~/.JCALibrary/JCALibrary.properties I set
com.cosylab.epics.caj.CAJContext.auto_addr_list = true
then the example works.
1b) context = CHANNEL_ACCESS_JAVA
However if I set auto_addr_list= false and add the IOC host IP address to:
com.cosylab.epics.caj.CAJContext.addr_list
then the example doesn't work, I get error:
gov.aps.jca.TimeoutException: pendIO timed out
caSnooper shows that the search request reaches the IOC host.
1c) context = CHANNEL_ACCESS_JAVA
On a machine with two NICs I set
com.cosylab.epics.caj.CAJContext.auto_addr_list = true
then a search request is sent on one of the two NICs. For one machine the correct NIC is chosen and the example works.
For another machine the wrong NIC is chosen and the example does not work.
[ the next two illustrate a known problem, reference: http://www.aps.anl.gov/epics/tech-talk/2009/msg01840.php ]
1d) context = CHANNEL_ACCESS_JAVA
on a machine on another sub-net connected through a gateway
auto_addr_list = true
example does not work, error
gov.aps.jca.TimeoutException: pendIO timed out
1e) context = CHANNEL_ACCESS_JAVA
on a machine on another sub-net connected through a gateway
auto_addr_list = false, add gatewyt IP address to addr_list
example works.
2) context = JNI_SINGLE_THREADED
I get error:
gov.aps.jca.CAException: Unable to create context
I have set
gov.aps.jca.jni.epics.linux-x86.library.path
and
gov.aps.jca.jni.epics.linux-x86.caRepeater.path
in ~/.JCALibrary/JCALibrary.properties.
What else could go wrong?
Any help appreciated,
