Publish/subscribe migration log file

The publish/subscribe migration log file is called amqmigmbbrk.log. It shows the details of the migration.

Identifying subscriptions in the log file or error messages

The log file identifies a subscription in the log file or an error message by listing its properties, including its topic string. The topic string can be up to 10,240 characters long, and is expressed in Unicode in the broker. The topic string might be too long or contain characters that cannot be represented in the current character set.

To identify subscriptions precisely, the migration process assigns a sequence number to every broker subscription that it encounters. The sequence starts at 1. When a subscription is identified by the migration process, the identification includes the sequence number, and anything else that is known about the subscription.

You can use the mqsireportproperties broker command to list subscriptions in the broker in the same order as the migration process. For example, the fourth subscription that the migration process counts is also the fourth that is listed by mqsireportproperties. With this information, you can correlate the sequence number from the log file or error message with the subscription in the broker.

The broker command to list the subscriptions is as follows:

mqsireportproperties brokername -e default -o DynamicSubscriptionEngine -r

To store the results in a file called, for example, outfile.txt, the command is as follows:

mqsireportproperties brokername -e default -o DynamicSubscriptionEngine -r > outfile.txt

Example

The following log file lists the actions that have been performed by a successful migration process. It shows the migration of subscriptions, ACLs, and retained publications.
