After upgrading to 10.3 - have been able to successfully convert DDMDB from MyISAM to InnoDB tables. However, the Secondary Archive Manager is showing errors when attempting to sync to Primary such as the following:
Jan 18 23:10:33 : Failed to sync events.
Jan 18 23:10:33 : Starting sync of events from primary ArchMgr
Jan 18 23:10:33 : Last event synchronization time is Jan 18 23:10:33
Jan 18 23:20:33 ERROR TRACE at CsEventMgr.cc(2528): Failure detaching from primary ArchMgr
Spectrum 10.3 or later
Copy the Primary DDMDB database to Secondary to ensure the databases are in sync.
