Abstract
A semi-dynamic load balancer for a transaction processing system reallocates transaction types among computers in the system as a group rather than as individual transactions. Statistical data is accumulated in an affinity matrix which records the number of times a transaction type i was blocked by transaction type j was holding a lock on a data item that transaction type i wanted to access. When an overloaded computer is detected, transaction types are reallocated on the computers of the system according to a transaction type routing table which is updated based on data from the affinity matrix.
