ORA-31495

Error: ORA-31495: error in synchronous change table on "string"."string"

Causa: There was an error originating from this synchronous change table.

Another possible cause is that there is a problem accessing the synchronous change table.

Acción: Check further error messages in the stack for more detail about the cause. If there has been schema redefinition, drop and recreate the synchronous change table.
