Change DB Purge Without OAMP
The CVP Reporting Server creates a Windows batch file cvppurge.bat that runs a Java backend code to start the db purge process. This file is located in C:\Cisco\CVP\bin.
This batch file is scheduled to run through the Windows Scheduler on each individual CVP Reporting Server. The Reporting Server is given two Windows Scheduler tasks, CVPDBMidDayPurge and CVPDBNightlyPurge. Each task corresponds to the mid-day Purge and Nightly Purge activities respectively mentioned in the Step 5 of the normal db schedule steps.
MidDayPurge and NightlyPurge use the same cvppurge.bat file however, different parameters feed into the batch file for different purge activities.
The db purge time can be changed through Windows Scheduler Tasks on each invidual CVP Reporting Server.
