Environment

Release : 11.0.2

Component : NQSAMC - NETQOS SA MGMT CONSOLE

Resolution

Ran through the steps below
1. Added Set "innodb_log_checksums = ON" to the my.ini under the innodb section of the file and saved it.

2. Deleted the 2 log files like  \CA\Mysql\data\ib_logfile*.

3. Start The CA Mysql service which may take some time as it was creating new ib_logfiles.

4.  Remove the "innodb_log_checksums = ON" from the my.ini and restart CA Mysql and all services.
