| HELP!!! I have a dedicated channel to an AIX queue manager, which uses SSL. I need to convert this channel to a share channel in a queue sharing group. Can a shared channel use SS since the label of the certificate specifies the MQ queue manager name that the channel is defined on? |

what are shared channels? 
shared Queues are shared in QSG on a Coupling Facility,
Queuemanagers can share queues,
but channels are from QM to QM...

Shared channel summary
Shared channels differ from private channels in the following ways:
Private channel
Tied to a single channel initiator.
Outbound channel uses a local transmission queue.
Inbound channel started through a local port.
Synchronization information held in SYSTEM.CHANNEL.SYNCQ queue.
Shared Channel
Workload balanced with high availability.
Outbound channel uses a shared transmission queue.
Inbound channel started through a generic port.
Synchronization information held in SYSTEM.QSG.CHANNEL.SYNCQ queue.
You specify whether a channel is private or shared when you start the channel. A shared channel can be started by triggering in the same way as a private channel. However, when a shared channel is started, WebSphere MQ performs workload balancing and starts the channel on the most appropriate channel initiator within the queue-sharing group. (If required, you can specify that a shared channel is to be started on a particular channel initiator.)
Shared channel status
The channel initiators in a queue-sharing group maintain a shared channel-status table in DB2. This records which channels are active on which channel initiators. The shared channel-status table is used if there is a channel initiator or communications system failure. It indicates which channels need to be restarted on a different channel initiator in the queue-sharing group. |

ok, hadn't read that. still in the QSG you don't have 2 Queuemanagers with the same name... so each QM on the MF side has it's own certificate talking via the 'shared' channel to the one AIX QM...
