To resume processing, use the imsimta qm start command to restart the channel. In the following example, the conversion channel is started:
imsimta qm start conversion
For more information on the imsimta qm start and imsimta qm stop commands, see imsimta qm in Sun Java System Messaging Server 6.3 Administration Reference.
The command imsimta qm start/stop channel may fail if run simultaneously for many channels at the same time. The tool might have trouble updating the hold_list and could report: QM-E-NOTSTOPPED, unable to stop the channel; cannot update the hold list. imsimta qm start/stop channel should only be used sequentially with a few seconds interval between each run.
If you only want the channel to run between certain hours, use the following options in the channel definition section in the job controller configuration file:
urgent_delivery=08:00-20:00 normal_delivery=08:00-20:00 nonurgent_delivery=08:00-20:00
