  • How to purge SQL database historical data 

    is the subject of the discussion as they are not receiving any response can anyone one confirm after doing the defined settings will DB wipe all the data first ?

  • Your question isn't clear at all. DPA should run a nightly clean of data the default it for it to start at 10 PM. DPA local application server time. The start time can be controlled with the advanced option CLEAN_START_HOUR. When it runs it should clean data based on DPA retention settings that are also in advanced options CLEAN_DAYS_OF_DETAIL, CLEAN_DAYS_OF_TEN_MINUTE_TREND, CLEAN_DAYS_OF_TREND 

    The default for example on CLEAN_DAYS_OF_DETAIL is 30 days. Cleaners will run to clear the oldest days keeping 30. Note days in that 30 days do not need to be consecutive days. If for example the monitors were off for a time there will simply be a gap in data for when they were off. It's a simple count of days oldest deleted first. 

    The sentence above asked if DPA will wipe data after a defined setting but, didn't even list a setting. It makes it difficult to answer a question when the question isn't clear.
