After migrating to 8.x version the USM portlet is not able to open.
The udm_manager probe has been introduced on the 8.1 version. If you migrate from a previous version before 8.1 and now you are not able to open the USM portlet you may see these errors:
message (11) command not found, Received status (11) on response (for sendRcv) for cmd = 'getUdmDatabaseUrl'
udm_manager log message:
Exception establishing Datomic connection: Malformed escape pair at index 129: datomic: and you are able to see the database password error like below:
In the password field you see something like % ' * '
ugs shows an error as well:
Oct 01 18:59:08:434 [main, ugs] Starting UDMservices Oct 01 18:59:08:771 [main, ugs] Failed to resolve UDM configuration from hub. Attempting to load UDM from UGS configuration Oct 01 18:59:14:025 [main, ugs] Failed to start UGS. Reason: Oct 01 18:59:14:028 [main, ugs] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datomicSchemaMigrator':
The root cause for this is the udm_manager probe does NOT support special characters like % *
Deactivate the data_engine then change the password on the DB and start the data_engine.
Make sure you also recycle the wasp probe.
After the password is changed and no longer includes any special characters, the issue will be solved.
