Examples of com.sleepycat.je.rep.txn.ReadonlyTxn

com.sleepycat.je.rep.txn.ReadonlyTxn
A ReadonlyTxn represents a user initiated transaction on a Replica. As its name implies it is used to implement the read-only semantics for access to the replicated environment on the Replica. In addition, it uses the transaction hooks defined on Txn to implement the ReplicaConsistencyPolicy.

        txnConfig.setConsistencyPolicy(policy);
        txnConfig.setReadUncommitted(true);


        Txn txn = null;
        try {
            txn = new ReadonlyTxn(rImpl, txnConfig);
            RepGroupImpl group = fetchGroup(groupName, dbImpl, txn);
            /* Correct summary info since we are reading uncommitted data */
            group.makeConsistent();
            txn.commit();
            txn = null;
