Invalid Change Log Format on Delta Import from IDB 5.1

Topic collaborators

Getting an error on an IDB 5.1 MA in the production environment, all Delta Imports are failing and taking an extended period of time to fail. IDB logs indicate that data is being returned (as per screenshot below), however the MIM MA errors as per the below italicised text.

The extensible extension returned an unsupported error.
The stack trace is:

"Unify.Product.IdentityBroker.LdapOperationException: Invalid change log format.

Given the impact on the production environment I will need to run a full import to attempt to restore service.

Are you able to extract the failing change log entry from the database? It should be in the set of entities immediately prior to the time that the end log entry was raised. A rawcap would be helpful too if that was possible.

Thanks.

Hi Adam - attached is a log of change entries however am unable to determine based on the timestamps which are relevant. Unfortuantely can't run a rawcap as I'm currently running a full import.

Thanks - Andrew.

Hi Adam,

Full imports are not restoring delta import functionality at all and they are taking at least 5 hours to run. Can we please escalate this issue as we need delta imports to meet business requirements.

Thanks,
Tom
