Hi, I am trying to sync a bidirectional MySql DB using sync framework(so few syncs about mysql? I only found some examples about oracle or
firebird which helps little).
When doing the synchronization it always said
"ReplicaId cannot be null" as shown below:
VERBOSE, OPSystem.vshost, 9, 07/11/2014 03:30:29:277, Executing Command: db_opsSync.sp_GetTimeStamp
VERBOSE, OPSystem.vshost, 9, 07/11/2014 03:30:29:278, Parameter: @sync_new_timestamp Value: Skipped since Not Input/InputOutput
VERBOSE, OPSystem.vshost, 9, 07/11/2014 03:30:29:337, Executing Command: SELECT scope_id, scope_local_id, scope_sync_knowledge, scope_tombstone_cleanup_knowledge, scope_timestamp FROM db_opsSync.ScopeInfo WHERE scope_name = @sync_scope_name
VERBOSE, OPSystem.vshost, 9, 07/11/2014 03:30:29:338, Parameter: @sync_scope_name Len: 8 Value: customer
ERROR , OPSystem.vshost, 9, 07/11/2014 03:30:29:507, Caught exception while getting changes: System.ArgumentNullException: Value cannot be null.

The scope table is :
CREATE TABLE db_opsSync.ScopeInfo(
scope_local_id int NOT NULL AUTO_INCREMENT UNIQUE ,
scope_id char(36), -- for MySqlDbType.Guid, VARBINARY(16) UNIQUE cannot work either!
scope_name varchar(100) NOT NULL PRIMARY KEY,
scope_sync_knowledge varbinary(10000) null, -- for MySqlDbType.VarBinary ,
scope_tombstone_cleanup_knowledge varbinary(10000) null, -- varbinary(max) NULL,
scope_timestamp Timestamp,
scope_cleanup_timestamp bigint -- bigint
);
Anyone knows about the reasons? Thanks in advance...
