Diagnosis

Take the output of the accounts and account_credential tables within the eum_db schema of the Controller database.

 

Example:

./controller.sh login-db
use eum_db;
select * from accounts;
select * from account_credential;

 

Note: The account name within the accounts table must match that of the account_credential table. The number of records must be the same.

 

Solution

If the accounts table is purged before provisioning the license, there can be a mismatch in the number of records within the two tables.

 

To resolve this issue, delete the mismatching account_name row from the account_credential table. Then restart the EUM Processor.

 

Example: 

delete from account_credential where account_name = 'mismatched_account_name';
