Restarting stopped channels

 

When a channel goes into STOPPED state (either because you have stopped the channel manually using one of the methods given in Stopping and quiescing channels, or because of a channel error) you have to restart the channel manually.

To do this, issue one of the following commands:

• The START CHANNEL MQSC command

• The Start Channel PCF command

• the WebSphere MQ Explorer

• other platform-specific mechanisms, as follows:

  For z/OS:

  The Start a channel panel

  For i5/OS:

  The STRMQMCHL CL command or the START option on the WRKMQMCHL panel

For sender or server channels, when the channel entered the STOPPED state, the associated transmission queue was set to GET(DISABLED) and triggering was set off. When the start request is received, these attributes are reset automatically.

If the channel initiator (on z/OS) or queue manager (on distributed platforms) stops while a channel is in RETRYING or STOPPED status, the channel status is remembered when the channel initiator or queue manager is restarted. However, the channel status for the SVRCONN channel type is reset if the channel initiator or queue manager stops while the channel is in STOPPED status.
