Use Partitioning Rules

Partitioning rules can also reduce contention, but require a clear understanding of your transaction profile.

• The Transaction Name Rule
  Find out if transactions have transaction names, and if the contention is caused by transactions with the same name. Try setting the transaction name rule, which forces transactions with the same name to be sent to the replicate one-by-one.
• The User Name Rule
  Setting the user name rule may help reduce contentions caused by transactions processed in parallel from the same user ID.
• The Origin Begin and Commit Times Rule
  The time rule forces serial execution of transactions with nonoverlapping commit/begin times.
• Combine Partition Rules
  You can combine rules. The first rule to be satisfied takes precedence.
