File qualifiers are typically specified in the AFNAME key of a snapapp table.
They modify the standard behavior of the standard Midas library routines as noted.
In the snapapp table they need to be specified in quotes if there are more than one.
For example:
AFQUAL="FUNC=ICEMULTI,THROTTLE=200"
or
AFQUAL="RG=IFS"
The qualifiers specific to ICE file are:
~Secfion RG=type - Specifies the Resource Group to handle this file.
The high speed ICE recorders use the Ice File System to perform direct IO to the disk arrays. This does not work on non-Ice system installations.
Contents
FUNC=f - Specialized function for the Ice Archiver class
f=ICEMULTI - Seperates channelized data into ICE multicast packets f=SDDSMULTI - Seperates channelized data into SDDS multicast packets f=SDDSUNPACK - Splits a stream with multiple multicast addressa into seperate streams
PKTLEN=n - Packet data length in bytes
THROTTLE=n - Maximum data rate to push to network
This is needed for some channelizer scenarios as a large chunk of data becomes available to transfer at once and pushing the entire block to the network at full rate may cause packet drops.
