ibm mq - When process is a Messaging channel agent in Message channel, what's the MCA in MQI channels.? -


when defining messages channels sdr channel, have mcatype process. when ever messages comes transmit queue, process start channel acting agent ( mca ).

amq8414: display channel details. channel(system.def.sender) chltype(sdr) mcatype(process)

if so, mca in case of mqi channels, how channel started let messages process application side?

mcatype has 2 possible values, process or thread. tells mq product how run channel, ie, whether run process, i.e. runmqchl process, or whether run thread of pool processes, amqrmppa process. applies outbound channels, i.e. start or initiate channel conversation. (it applies cluster-receivers sole purpose of building cluster-sender channel it, attribute not used cluster-receiver itself).

for inbound channel types not apply. way choose between thread , process inbound channels threads, use normal mq listener (this recommended way), , processes, use inetd.

so mqi channels, svrconn channel type, run threads of pool processes unless use inetd. using inetd not recommended.

they started listening process (either mq listener or inetd) catching socket creation, , handing off process (amqrmppa or amqcrsta) accept , receive data from.
