Cluster Administration

The goal of cluster administration is to ensure that clusters and servers work smoothly, and scale over time. By default, the Unwired Platform is installed as a one-node cluster. The one-node cluster is supported in development or test environments. Production deployments of Unwired Platform are likely to require multiple nodes. Cluster administration is mostly a nonroutine administration task.

Cluster administration tasks
Task Frequency Accomplished by
Installing the cluster One-time installation per cluster Unwired Platform installer
Setting up Relay Servers One-time initial installation and configuration; occasionally adding servers to the cluster Manual installation; manual setup using configuration files.
Suspending and resuming server nodes On demand, as required Sybase Control Center
Setting cluster properties, including cache database settings, monitoring database setup, and so on Once, or as cluster changes require Manual configuration using files and .BAT scripts.
Configuring the cluster to:
  • Set the configuration cache properties
  • Set the solution manager URL
  • Set the replication ports and properties
  • Set the messaging synchronization ports
  • Set the amount of data that can be downloaded through an HTTP connection using the BlackBerry MDS
  • Set the management ports for communication requests from Sybase Control Center
  • Configure the client dispatcher
  • Set how applications handle DCN requests sent though an HTTP GET operation
  • Create security profiles for secure communication
  • Set up secure synchronization
  • Tune server performance
 Post installation configuration with infrequent tuning as required See Sybase Control Center for Sybase Unwired Platform>Administer> Clusters
Setting cluster log file settings for Unwired Server system components Once, unless log data requirements change See Sybase Control Center for Sybase Unwired Platform>Administer>>Clusters
Administering the runtime databases Routine to ensure that the database server is monitored and backed up, that there is sufficient space for Unwired Platform metadata and cached data tables, and that performance is within acceptable limits (performance tuning) Established processes and command line utilities. Consult with your database administrator.
Reviewing licensing information, including total licensed devices and currently used licenses count Occasional, or as device user registration and deregistration occurs Sybase Control Center.
