Broker Failure (100-1010): A failure occurred on the Broker - udpate
The message “Broker Failure (100-1010): A failure occurred on the Broker. The error code is 306 and the message is ‘’.” indicates that the “IntegrationServer” client group which your IS Broker clients use, has set “Access Label” to “Required”. With this setting the Broker requires any client connecting with that client group to have an access label assigned by an access label adapter (ALA).
In MWS please go to Messaging > Client Groups > “IntegrationServer” > Configuration tab and un-check “Access Label required” if this group property has been set here unintended.
Another reason for this error message could be that the Integration Server lost its identity (i.e. distinguished name or DN and an authenticator name (the issuer DN of the client’s SSL certificate)) for connecting to the Broker. Reconfiguring the identity should solve the issue in this case.
Please review Broker Admin guide for chapter “Using Access Labels” for details on this topic.
