After the conversion, perform a Configuration Update ([B], [B], [D], [A] from theMain Menu) to each affected node, then re-IPL the node ([B], [B], [B] from theMain Menu).Database Concurrency Operations"Partitioned Network" on page 3-12, describes how more than one database mastercan come to exist in a network. Depending on the changes made while the networkwas partitioned, databases in all ICPs, INMs, and NMPs may not automatically syn-chronize when the network is reconnected. If they do not, printer messages willindicate that it is necessary to perform database concurrency operations.If a message has instructed you to perform concurrency opera-tions, do them in this order:1. Clear Remote Master,2. Enable Backouts (if requested),3. Database Recovery – only if needed.These operations are accessed from the Database Concurrency Operations Menu([B], then [C] from the Main Menu).Clearing a Remote MasterWhen a partitioned network is reconnected, each master reports that there is a multiplemaster, and identifies the other master(s). The decision as to who will give up masterstatus should depend on what changes were made to each database. This is usuallydetermined by network operators discussing the changes and making the decision.At the INM/NMP that will ultimately be the only master, perform the following steps(you must have master status to do this):1. Press [B] at the Database Concurrency Operations Menu.2. Enter the node number of the master INM/NMP to be cleared.3. Check all printed messages, to determine whether anything more must be done.4. Press [F3] once to return to the Database Concurrency Operations Menu, or threetimes to return to the Main Menu.
