Cluster AdministrationLocate this document in the navigation structure

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

See Designing the Landscape in Landscape Design and Integration.

Table 1: Cluster administration tasks
Task Frequency Accomplished by
Installing the cluster One-time installation per cluster SAP Mobile 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 SAP 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.
Tuning the server performance. Post installation with infrequent tuning as required SAP Control Center.
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 SAP 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  
Setting cluster log file settings for SAP Mobile Server system components Once, unless log data requirements change  
Administering the runtime databases Routine to ensure that the database server is monitored and backed up, that there is sufficient space for SAP Mobile 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 currently used licenses count Occasional, or as device user registration and deregistration occurs SAP Control Center.
