NAME¶
ltpdriver - LTP transmission test program
SYNOPSIS¶
ltpdriver remoteEngineNbr clientId nbrOfCycles
greenLength [
totalLength]
DESCRIPTION¶
ltpdriver uses LTP to send
nbrOfCycles service data units of
length indicated by
totalLength, of which the trailing
greenLength bytes are sent unreliably, to the
ltpcounter client
service process for client service number
clientId attached to the
remote LTP engine identified by
remoteEngineNbr. If omitted,
length defaults to 60000. If
length is 1, the sizes of the
transmitted service data units will be randomly selected multiples of 1024 in
the range 1024 to 62464.
Whenever the size of the transmitted service data unit is less than or equal to
greenLength, the entire SDU is sent unreliably.
When all copies of the file have been sent,
ltpdriver prints a
performance report.
EXIT STATUS¶
- "0"
- ltpdriver has terminated. Any problems encountered during operation
will be noted in the ion.log log file.
- "1"
- ltpdriver was unable to start, because it could not attach to the
LTP protocol on the local node. Run ltpadmin to start LTP, then try
again.
FILES¶
The service data units transmitted by
ltpdriver are sequences of text
obtained from a file in the current working directory named
"ltpdriverAduFile", which
ltpdriver creates automatically.
ENVIRONMENT¶
No environment variables apply.
DIAGNOSTICS¶
Diagnostic messages produced by
ltpdriver are written to the ION log file
ion.log.
- ltpdriver can't initialize LTP.
- ltpadmin has not yet initialized LTP protocol operations.
- Can't create ADU file
- Operating system error. Check errtext, correct problem, and rerun.
- Error writing to ADU file
- Operating system error. Check errtext, correct problem, and rerun.
- ltpdriver can't create file ref.
- ION system error. Check for earlier diagnostic messages describing the
cause of the error; correct problem and rerun.
- ltpdriver can't create ZCO.
- ION system error. Check for earlier diagnostic messages describing the
cause of the error; correct problem and rerun.
- ltpdriver can't send message.
- LTP span to the remote engine has been stopped.
- ltp_send failed.
- LTP system error. Check for earlier diagnostic messages describing the
cause of the error; correct problem and rerun.
