Hi all,
I'm starting a process asynchronously from STAX via a <stafcmd /> to the
PROCESS service with a request like:
STAF ... PROCESS START COMMAND ... NOTIFY ONEND ...
So this defaults to starting the process asynchronously and doesn't wait
for the process to complete.
What I've found is that on win32 if the process completely fails to
start, say for example because a required .dll is not on the PATH, tnen
when I come to later check back on the process with:
STAF ... PROCESS QUERY HANDLE <handle>
The returned process info looks something like:
{
'rc': None,
'endTimestamp': None,
'command':
'F:\\worgit\\ospli\\testsuite\\tests\\hello\\ccpp_hello_pub',
'startMode': 'Async',
'pid': '2660',
'startTimestamp': '20100923-14:34:46',
'workload': None,
'handle': '91',
'staf-map-class-name': 'STAF/Service/Process/ProcessInfo',
'shell': None,
'userName': None,
'title': None,
'parms': '-ORBListenEndpoints iiop://:23232 -ORBInitRef
ccpp_hello_sub=corbaloc:iiop:rhel53a:23233/ccpp_hello_sub',
'key': '1',
'handleName': None,
'focus': 'Background',
'workdir': 'F:\\worgit\\ospli\\testsuite\\tests\\hello'
}
... i.e. the rc is None, there is a PID, & there is no endTimeStamp. So,
it's basically indistinguishable from a running process.
This contrasts with Linux where you can see:
{
'rc': '127',
'endTimestamp': '20100923-14:22:16',
'command': '/home/dds/sm/ospli/testsuite/tests/hello/ccpp_hello_pub',
'startMode': 'Async',
'pid': '12461',
'startTimestamp': '20100923-14:22:15',
'workload': None,
'handle': '112',
'staf-map-class-name': 'STAF/Service/Process/ProcessInfo',
'shell': None,
'userName': None,
'title': None,
'parms': '-ORBListenEndpoints iiop://:23232 -ORBInitRef
ccpp_hello_sub=corbaloc:iiop:beatrice:23233/ccpp_hello_sub',
'key': '1',
'handleName': None,
'focus': 'Background',
'workdir': '/home/dds/sm/ospli/testsuite/tests/hello'
}
... so a non zero return is present and an endTimeStamp.
Can you tell me please, is this by design and / or is there a workaround
or other way of detecting if an async process has failed to start on win32 ?
Cheers,
