Constructor Detail

TransactionServiceImp

public TransactionServiceImp(String name,
                             StateRecoveryManager recoverymanager,
                             UniqueIdMgr tidmgr,
                             long maxtimeout,
                             int maxActives,
                             boolean single_threaded_2pc,
                             RecoveryLog recoveryLog)

Create a new instance, with orphan checking set.

Parameters:

name - The unique name of this TM.

recoverymanager - The recovery manager to use.

tidmgr - The String manager to use.

maxtimeout - The max timeout for new or imported txs.

maxActives - The max number of active txs, or negative if unlimited. even for creation requests that ask for checks. This mode may be needed for being compatible with certain configurations that do not support orphan detection.

single_threaded_2pc - Whether 2PC commit should happen in the same thread that started the tx.

recoveryLog2 -
