' ### VBA Routine zum Löschen von Trace-Dateien
' ### Geschrieben von Marco Patzwahl, MuniQSoft GmbH
' ### (c) 2005 und 2006 Version 1.0
' ### Aufrufsyntax: del_trac.vbs <pfad> <tage>
' ### Löscht alle Trace-Dateien im Ordner <pfad>
' ### die aelter als <tage> sind
' ### Beispiel: del_trace.vbs D:\oracle\admin\o10g\udump 21
Dim oFSO
Set oFSO = Createobject("Scripting.FileSystemObject")
Dim oStartFolder
Dim oFolder
Dim oFile
Dim dKillDate
Dim dKillDays
Set Args = WScript.Arguments
sStartFolder=Args(0)
dKillDays=Args(1)
'Const STARTDIR = "D:\oracle\admin\o10g\udump"
'Const KILLDATE = "21"
dKillDate = CDate(Now() - CInt(dKillDays))
Set oStartFolder = oFSO.getFolder(sStartFolder)
For Each oFile In oStartFolder.Files
If oFile.DateCreated < DKillDate and Mid(oFile.name,Len(oFile.name)-
3) = ".trc" Then
oFile.Delete True

Hinweis: Sie können die Speicherdauer wieder kontrollieren durch:SELECT retention
FROM dba_hist_wr_control;

Hinweis:
Sie können auch die Lebensdauer des Tasks manuell einstellen (hier 3 Tage):
BEGIN
DBMS_ADVISOR.SET_TASK_PARAMETER (
task_name =>'MY_TASK',
parameter =>' DAYS_TO_EXPIRE',
value=>3);
END;

Hinweis:
Sie können natürlich auch Snapshots aus einem bestimmten Bereich löschen:
Snapshots manuell löschen. Hier im Beispiel von 22-32
BEGIN
DBMS_WORKLOAD_REPOSITORY.drop_snapshot_range (
low_snap_id => 22,
high_snap_id => 32);
END;
