Starting and Setting Up RTR 2.12 How RTR Selects Processing-states (Roles) for Nodes

The SHOW PARTITION command on each backend node is as follows:

The following description shows how sequence numbers are initially assigned in a simple partition with two backends named Bronze and Gold, and a router named Silver.

Router 2

7

Backend A

5

Backend B

1.A partition (with shadowing enabled) is started on node Bronze.

2.The partition on Bronze obtains sequence number 1 from the router and becomes the primary.

3.Another server on the same partition (with the same attributes) is started on Gold.

4.The partition on Gold obtains sequence number 2 from the router and becomes the secondary.

5.Node Bronze crashes and reboots (the partition sequence number on Bronze is reset to 0). The partition on Gold goes into Remember.

6.When the server starts, The partition on Bronze obtains sequence number 3 from the router and becomes the secondary, Gold now becomes the primary.

7.The network connection from node Silver to node Gold fails. The partition on Bronze becomes the primary. The partition on node Gold loses quorum and is in a wait-for-quorum state.
