Issue/Introduction

After upgrading to CAPM 20.2.5, event manager will not become "Available".  Both Resync buttons are greyed out.  Running small em update in mySQL does nothing (both with and without 'Where' clause): Process for EM is running 

mysql> use em;
Database changed
mysql> update data_sources SET LastEvent=0, ConsumerID=0 WHERE SourceName='Data Aggregator';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> use em;
Database changed
mysql> update data_sources SET LastEvent=0, ConsumerID=0;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 3  Changed: 2  Warnings: 0

Restarted services.  No help.

Please assist.
