This illustration shows the two steps required for grabbing the token.

Step 1: Identify True Owner

1. The replication site acct_ny.ny.example.com wants ownership of the row for the employee whose empno is 100.

2. The acct_ny.ny.example.com site determines the current owner of the row by querying the headquarters database, which is acct_hq.hq.example.com.

3. The acct_ny.ny.example.com site determines that current owner for the row is the site acct_sf.sf.example.com.

Step 2: Grab Ownership and Broadcast Change

1. The replication site acct_ny.ny.example.com locks the row locally and synchronously updates both the acct_ny.ny.example.com site and the acct_sf.sf.example.com site, making the owner of the row acct_ny.ny.example.com at both sites.

2. The acct_ny.ny.example.com site asynchronously updates all other replication sites to make the owner of the row acct_ny.ny.example.com.
