Wldf 9.2 diagnostic archive retirement

Question

Hi to all,
Is there a way to retire diagnostic data from weblogic 9.2 wldf WLS_DIAGNOSTICS000000.DAT? I am planning to setup a diagnostic module on our server and wondering if this diagnostic data can be retired, I have seen this feature in weblogic 10, Retiring Data from the Archives and wondering if there is an equivalent for this in weblogic 9.2. Eventually this diagnostic will grow and we need to manage this growth.
regards.

Hello,
WLS 9.x did not provide a configuration based data retirement feature. However, it provided operations on runtime mbeans which could be used to delete selected records. You can periodically execute a WLST script to remove older data. For example:
import sys
# Usage:
# java weblogic.WLST delete_old_data.py url username password keep_days
# eg, following will delete data older than 2 days from the harvester and events
# archives:
# java weblogic.WLST delete_old_data.py t3://localhost:7001 weblogic weblogic 2
def getParam(pos, default):
value=None
try:
value=sys.argv[pos]
except:
value=default
return value
url = getParam(1, "t3://localhost:7001")
user = getParam(2, "weblogic")
password = getParam(3, "weblogic")
days = getParam(4, 1)
try:
connect(user,password,url)
now=System.currentTimeMillis()
bound=(now - days*3600*24*1000)
serverRuntime()
cd('/WLDFRuntime/WLDFRuntime/WLDFAccessRuntime/Accessor/WLDFDataAccessRuntimes/HarvestedDataArchive')
print "Deleting records older than", days, " days from Harvester data archive"
deleted=cmo.deleteDataRecords(0L, bound, "")
print "Deleted ", deleted, " record(s) from Harvester data archive"
cd('/WLDFRuntime/WLDFRuntime/WLDFAccessRuntime/Accessor/WLDFDataAccessRuntimes/EventsDataArchive')
print "Deleting records older than", days, " days from Events data archive"
deleted=cmo.deleteDataRecords(0L, bound, "")
print "Deleted ", deleted, " record(s) from Events data archive"
except:
print "exception found"
Hope this helps.
