Can the channel process messages fast enough?

If there are messages building up on the transmission queue, yet you have found no processing problems, it can simply be that the channel cannot process messages fast enough. To identify if this is the case, do the following:

1. Issue the following command repeatedly over a period of time to gather performance data about the channel:

   DIS CHSTATUS(QM1.TO.QM2) ALL

2. Providing you have confirmed that there are no uncommitted messages on the transmission queue (detailed in Are the messages on the queue available?), check the XQTIME field. When the value of the XQTIME indicators are consistently high, or are increasing over this period, this indicates that the channel is not keeping up with the putting applications. In this situation try to determine why he channel is not keeping up, see the following:

   • Are there exits processing?

   • Is the network slow?

   • Is the channel using compression?
