Hi,
A user spotted and reported the following error/warning related to the MigrationManager and MigrationStatus, respectively:
My questions are:
- what is the MigrationManager and MigrationStatus?
- what could trigger these warnings/errors?
The DataMiner version here is 10.0.0-CU5.
Thank you for the help.
Hi João,
Not fully sure, but I would assume that the MigrationManager is responsible for the migration of specific Cassandra information to Elastic Search, which is automatically performed when moving from a 9.6 to 10.0 version. This typically applies to Job and SRM information which was stored in Cassandra in version < 10, and has been moved to Elastic Search since DataMiner 10.
I believe that there is also more details logs available in the SLMigrationManager.txt log file. Any chance that you could check these?
I'm assuming of course that Elastic Search is correctly running. That could maybe also be something to check.
Hi Leander,
Thank you, I was not aware of this detail. In this case there is no SRM in the project and the upgrade from 9.6 from 10 happened alreay a few months ago. The logs did not show any indication was well. It only read:
“2021/03/25 09:45:40.112|SLNet.exe|Initialize|CRU|0|35|Initializing MigrationManager…”
Also this agent does not have the license for SRM.
In the meantime I connected again to the agent and the warnings and errors are no longer there.
I would say this is “case closed” until further developments.
