Upgrading a Simple Load Balancing Cluster Installation

Where the cluster uses only the basic load balancing cluster support that is built into Unwired Platform.

1. Shut down all Sybase-related processes on cluster nodes in this sequence:
   • Secondary Unwired Servers – shut down services in this order:
     1. Sybase Unwired Server
     2. Sybase Control Center X.X
     3. Sybase Unwired SampleDB (not applicable to Enterprise Server Edition)
   • Primary Unwired Server – shut down services in this order:
     1. Sybase Unwired Server
     2. Sybase Control Center X.X
     3. Sybase Unwired SampleDB (not applicable to Enterprise Server Edition)
   • Data tier server – shut down these services, in any order:
     • Sybase Unwired CacheDB
     • Sybase Unwired ClusterDB
     • Sybase Unwired LogDataDB
     • Advantage Database Server®
2. Upgrade servers in this sequence, leaving Sybase services restarted on completion of each upgrade:
   1. Data tier.
   2. Primary node.
      Note: Do not begin upgrading any secondary servers until the primary server has completely finished restarting all its services after being upgraded.
   3. Secondary nodes.
