Udm_manager

window 2016

Resolution

 Follow the below step :-

In the " Raw Configure" GUI of the udm_manager, add the following key under the setup section:

"schema_transact_retries" and set the value to 5000.

Also increase the "schema_connection_timeout_minutes" value to 30. 

You may need to edit this parameter under "setup" > datomic > "memory_index_max". 

Out of the box this is set to 256 MB.  You may need to increase this to '512m' or higher.
