All Implemented Interfaces:

extends Object
implements TransactionLog

log prepare for the global xid xid and the list of TransactionBranchInfo branches

Specified by:

prepare in interface TransactionLog

Parameters:

xid - global xid for the transactions

branches - List of TransactionBranchInfo

Throws:
