Activiti REST Synchornisation failed with Database

[yahoopramod]

Hi,

Am Trying to start a process instance from An External REST API using Activiti REST,
but i can't able to start ,even i can't able to list the available Process definition's i deployed .Its Showing only Default Process Definitions.
Database I changed to MySQl for Both Activiti Explorer and Activiti REST,

is the problem with database  synchronization?
Can any body please help me how to go forward?

No there's no problem with database synchronization.
Do you see any error message appear in the log?
If the process definitions list only contains the default process definitions then there might be something wrong with your db configuration. Also be aware that the default paging size is 10.

Best regards,
