Hello,

I'm having trouble with my channel access calls on a vxWorks box. All
tries to create a channel fail and I can't figure out why.

_Whats happening_ when I call the functions of my application directly
from the vxworks shell:

0x1b79680 (t1): ERROR: Creation of channel for MCFG1OU008L:WaveDest has
failed. With state: 0
CA.Client.Exception...............................................
    Warning: "Normal successful completion"
    Context: "create channel DestWave: "
    Source File: ../epicsWrapper.c line 95
    Current Time: SUN DEC 31 1989 18:00:27.466666648
..................................................................

Output of ca_client_status(1): http://pastebin.com/m2172d560

_Environment:_
Target: vxWorks-ppc603_long
vxWorks Version 5.5
EPICS 3.14.9

EPICS_CA_ADDR_LIST=193.149.13.6
EPICS_CA_AUTO_ADDR_LIST=NO
EPICS_CAS_BEACON_ADDR_LIST=
EPICS_CAS_BEACON_PERIOD=200.0

The CA Server is on a different subnet. I added a default route to the
gateway (communication with ping works, no ports forwarded).

I used the makeBaseApp.pl script to make the iocApp and iocBoot skeleton.

For the st.cmd I'm very unsure what's necessary. As I don't need the
database and the ioc functionality, only client access function, I tried
loading only my iocApp on startup (without iocInit()).
I also tried it with the example startup file. The result seemed to be
the same.

What surprises me is that there is no ca_get() or ca_put():
-> lkup "ca_get"
ca_get_ioc_connection_count 0x0183f7f8 text     (smart.munch)
ca_get_host_name          0x0184e4a0 text     (smart.munch)
value = 0 = 0x0

I'll be glad for any suggestions.

Regards,
Felix
