Tuning RBS Synchronization

Tune your production environment after all components have been deployed and started.

1. Isolate the monitoring database from the CDB server.
   See Isolating and Setting Up Production Monitoring Databases.
2. Disable all enabled monitoring profiles that currently exist.
   Normally, monitoring in a cluster configuration occurs at two levels — the cluster and the domain. Sybase recommends that you turn off monitoring when assessing performance.
   1. In navigation pane of Sybase Control Center, click Monitoring.
   2. In the administration pane, select the profile name and click Disable.
   3. Validate that all monitoring is disabled by opening <UnwiredPlatform_InstallDir>\Servers\UnwiredServer\Repository\Instance\com\sybase\sup\server\monitoring\ MonitoringConfiguration\domainLogging.properties, and verifying that “status”, “enabled”, and “autoStart” are set to false.
   See Monitoring Profiles in the Sybase Control Center online help.
3. In Sybase Control Center, stop all Unwired Servers in all clusters.
4. Stop the CDB service on the data tier node.
5. Use the dblog utility to isolate the CDB disk and log on to fast storage.
   For details, see Using a Different Database and Log Path.
6. Set the new CDB thread count, pool size, and initial cache size.
   See Changing the Consolidated Database Server Thread Count and Pool Size.
7. Restart the CDB service and all Unwired Servers.
8. In Sybase Control Center, adjust the EIS connection pools to high values:
   1. In navigation pane of Sybase Control Center, click Connections.
   2. In the administration pane, set the Max Pool Size property for each EIS connection type.
      If the Max Pool Size property does not appear for a connection, you must manually add it.
9. In Sybase Control Center, update the Unwired Server RBS synchronization properties on the primary server.
   1. In the left navigation pane, click Servers>SeverName>Server Configuration.
   2. In the right administration pane, click the Replication tab.
   3. Adjust the synchronization cache size, and the replication thread count for the entire cluster.
   4. Repeat for all servers, so that each node has an equal thread count.
10. In Sybase Control Center, set thread stack size and JVM heap sizes for the server.
    1. In the left navigation pane, click Servers>SeverName>Server Configuration.
    2. In the right administration pane, click the General tab then click Performance Configuration.
    3. Adjust the thread stack size and JVM heap sizes to the new values.
    4. Repeat for all servers.
11. Restart all Unwired Servers.

• Changing the Consolidated Database Server Thread Count and Pool Size
  You can change the consolidated database (CDB) server thread count and maximum pool size as required. The procedure for this varies depending on the type of environment the CDB server is deployed to.
• Backing up Data and Mirroring Transaction Logs
  Mirror logs to make identical copies elsewhere on your network using SQL Anywhere utilities. Mirrored logs ensure runtime data is available and recoverable in the event of failure.
• Isolating a Monitoring Database From A Shared Server and Data Node
  Isolate a monitor database that has been installed to a development or test environment where the data tier and Unwired Server is installed on a shared host.
