Managing Domain Logs

Configure settings to perform logging for your applications whenever needed.

Messages are logged for synchronization, data change notification, device notification, package, user, and cache activities among others. The following aspects of logging are important to ensure that performance of the applications is minimally impacted and the required data is collected. In production system, it may be used to diagnose application issues. A developer may also use it in a development or test environment for debugging purposes.

The critical steps for configuring the domain log include:

Set up the proper domain log configuration. A domain log configuration sets the server behavior for writing data to database, automatic purge, and data source where the log data is stored. A default configuration is created for you, however you will likely want to customize this configuration for your environment.
By default, log data is flushed every 5 minutes. In development and debugging scenarios, you may need to set the flush behavior to be immediate. Set the Number of rows and Batch size properties to a low number. You can also disable flush, which results in immediately persisting changes to the database. If you are setting up immediate persistence in a production environment, you may experience degraded performance. Use persistence with caution. This configuration can be done by platform administrator only.
Create a logging profile. A logging profile allows a platform administrator or domain administrator to define the target of logging. Unwired Server can be configured to log messages for a specific application or package, security configuration or user, device connection, and/or backend connection type or specific one, or a combination thereof.
Review the captured data. A platform or domain administrator can review logged data using log filters. The filters enable you to retrieve data logged for a specific thread, application, user, connection, etc. among other options.

All of the above steps are performed in Sybase Control Center. Refer to the topic group Domain Log in Sybase Control Center online help for details.

Planning for Domain Logging
Domain logging is an option for obtaining detailed information on all aspects of device, user, application, domain, and data synchronization related activities. The capability can have an adverse influence on system performance, so planning is important before using it on a production system.
Enabling and Configuring Domain Logging
Configure auto purge, flush threshold, and flush batch size settings to determine how long domain log data is retained, how frequently it is written to database from server nodes, and set a domain log database connection to configure where domain log data is stored.
Reviewing Domain Log Data
An administrator reviews logged data by creating log filters. The filters enable you to retrieve data logged for a specific thread, application, user, connection, among other options.
