Class TransactionLeaseRenewalConfig

java.lang.Object
org.openspaces.core.transaction.manager.TransactionLeaseRenewalConfig
public class TransactionLeaseRenewalConfig extends Object
Allows to configure transactions to be renewed automatically when using AbstractJiniTransactionManager and its different sub-classes.

Will cause a transaction to be renewed each setRenewDuration(long) (which should be lower than the transaction timeout). Defaults to 2 seconds.

Allows also to set the setRenewRTT(long) which controls the expected round trip time to the server. Should be lower than the then the renew duration. Defaults to 1 second.

The transaction renewal also allows to configure the pool size of renewal managers that will be used to renew transactions. It defaults to 1 and under heavy load of transactions with renewals should probably be higher.
