Configure news event log clean-upEdit settings in the communities-config.xml file to define the interval at which the EventLogCleanup task runs.
Before you beginTo edit configuration files, use the IBM WAS wsadmin client. See Starting the wsadmin client for details.
About this taskCommunities has a database table called EVENTLOG. When certain predefined events occur in communities, those events are written to the table, which increases in size as more and more events are added. The EventLogCleanup task is used to clean up the EVENTLOG database table by removing events that are older than 30 days. When you install IBM Connections, by default, the EventLogCleanup task is scheduled to run every day, every 3 hours, and to delete events older than 30 days. If you want to modify the default schedule to run more or less frequently, you can do so by changing the WAS Cron schedule for this task. For more information about the WAS scheduler, see Scheduling tasks.
ProcedureTo configure the EventLogCleanup task...
- From the dmgr host:
If prompted to specify a service to connect to, type 1 to pick the first node in the list. Most commands can run on any node. If the command writes or reads information to or from a file using a local file path, pick the node where the file is stored.
- Check out the Communities configuration files using the following command:
- <working_directory> is the temporary working directory to which the configuration XML and XSD files are copied. The files are kept in this working directory while you make changes to them.
Note: AIX and Linux only: The directory must grant write permissions or the command will not run successfully.
- <cell_name> is the name of the WAS cell hosting the IBM Connections application. This argument is required. If you do not know the cell name, you can determine it by typing the following command in the wsadmin command processor:
To view the current configuration settings, use the following command:
Note: After updating any of the configuration settings, you can use this command again to display your updates.
To modify the setting for the scheduled task, use the following command:
- <property> is one of the editable Communities configuration properties.
- <value> is the new value with which you want to set that property.
The following table displays the EventLogCleanup property and provides additional information regarding the property and the type of data that you can enter for it.
Table 1. EventLogCleanup properties
Property Description task.EventLogCleanup.enabled Enables or disables the event log cleanup task.
This property accepts the following values: true or false.
task.EventLogCleanup.interval Specifies the interval at which the event log cleanup task runs. The parameter is specified in Cron format. For more information about using the Cron format, see Scheduling tasks.
When you change the interval property, the new schedule is registered the next time that Communities is started on any server in the Communities cluster (if there is one).
When you install IBM Connections, the default setting for this task is 0 30 0-23/3 ? * *, which means that it will run every 3 hours at 30 minutes past the hour.
In the following example, the EventLogCleanup task is set to run once every hour at 32 minutes past the hour.
CommunitiesConfigService.updateConfig("task.EventLogCleanup.interval", "0 32 0-23/1 ? * *")
After making changes, check the configuration files back in, and do so during the same wsadmin session in which you checked them out for the changes to take effect. See Apply property changes in Communities for information about how to save and apply your changes.
