How to disable the internal datatrimmer in the Managing Server to preserve data.


The ITCAM for Application Diagnostics Managing Server comes built-in with an internal datatrimmer.   If you are pulling some Application or Capacity Reports and not seeing data past a certain time, it may be due to the internal datatrimmer that's running.   If you want to see the data in your Reports, you should first disable the internal datatrimming process.  To do that, please follow these steps:

1) Open up your $MS_HOME/etc/ file.

Scroll down towards the bottom and look for ENABLE_DATATRIMMER.  If this parameter is set to true, then go ahead and change it to false.  Save your file.

2) Do the same for $MS_HOME/etc/ also.

3) Now you will simply restart your Archive Agents (both AA1 and AA2).  If this is a production system, you may want to reschedule this

$MS_HOME/bin/ aa1 stop

$MS_HOME/bin/ aa2 stop

Wait for about 30 seconds for all processes to stop, then start them one by one.

$MS_HOME/bin/ aa1 start

$MS_HOME/bin/ aa2 start

Wait for about 2 to 3 minutes for all your DC's to reconnect again, then check status.

$MS_HOME/bin/ aa1 status

$MS_HOME/bin/ aa2 status

The internal datatrimmer is now disabled.  You will need to wait 24 to 48 hours for some data to get generated back into the database.  Then run your Report and see if you are getting data now.

(Note: Since you have now disabled internal triming, your octigate database could fill up.  So, you should set up your external datatrimmer script ( to trim data periodically, say, every 7 to 10 days for database optimization.)

Good luck. Smile
