Abstract
A system and article of manufacture maintain the original order of a sequence of transactions originating from a source database and being replicated to a target database. A lockable object is associated with each transaction of the sequence of transactions from the source database. Each transaction has one or more transactional events. The transactions of the sequence of transactions have an order. The order is a commit order of the transactions in the source database. The lockable object is based on the commit order. A lock is attempted to be obtained on one or more lockable objects associated with one or more transactions of the sequence of transactions which precede a particular transaction of the sequence of transactions. In response to being unable to obtain the lock, the one or more transactional events of the one or more transactions which precede the particular transaction are serially processed.
