You run the prune command as part of the perfDWTool.
Remember: Run the prune command during
a time when the server is not busy.
Before you begin
Before you run the prune command, complete the following tasks:
- Ensure that you have installed or upgraded your Performance Data Warehouses to the latest version of IBM® BPM.
- Start the Performance Data Warehouse. If you are running in a clustered environment, ensure that all servers in the cluster are running.
- Create a backup of the performance database.
- Go to the following directory: install_root\profiles\profile_name\bin.Remember: perfDWTool must be run from an active node in the support cluster.Note: The perfDWTool.sh or perfDWTool.bat file might not be located in the Node1Profile/bin directory by default. If it is not, move the perfDWTool.sh or perfDWTool.bat file from the DMgr/bin directory to the Node1Profile/bin directory.
Command syntax
Run the prune command by using the following syntax:
perfDWTool.sh -u user_name -p password -nodeName node_name
prune -daysOld number-of-days-old
perfDWTool.bat -u user_name -p password -nodeName node_name
prune -daysOld number-of-days-old Where -daysOld indicates the age of the data that should be removed. The age is based on the current server time.
For example, suppose, at 4:00 p.m. on October 24, you use the prune command with the -daysOld parameter set to 2. All data that is older than October 22 at 4:00 p.m. is deleted.
Note the following information about
the number-of-days-old argument:
- It can contain only numeric characters.
- It must be a value greater than 0.
- If you enter 0 or a negative number, or if you include alphabetic or special characters, an error is returned.
