If you were using 2.X there is a setForceWriteLock() option which would have worked for you. As a workaround, you could do this: 1. Configure your cache with R_R. 2. Start your transaction. 3. Whenever you need to READ a node, first WRITE a dummy value to it. E.g., cache.put("/root/subroot/A", "dummy", null); This will force a write lock on the node, and no other thread will be able to read it. 4. Perform your READ. 5. Commit your tx.
