Audit und Compliance des Datenbankzugriffs automatisieren

Verwenden Sie die PowerShell- und Bash Shell-Skripte in diesem Abschnitt, um EPM Automate-Befehle zum Erfassen von Audit- und Compliance-Daten im Zusammenhang mit dem manuellen Datenbankzugriff zu nutzen.

Mit diesen Skripten können Sie folgende Aufgaben ausführen:

Aktivitätsbericht für den aktuellen Tag herunterladen
Bericht parsen, um zu bestimmen, ob manueller Datenbankzugriff für die Umgebung gemeldet wird
./reports/dataAccessAuditReport.txt relativ zu dem Verzeichnis erstellen, in dem Sie das Skript ausführen. Im Bericht werden der Zeitpunkt des Datenbankzugriffs sowie der SQL-Befehl aufgelistet, der ausgeführt wurde. Dies ist eine kumulative Datei, in der die aktuellsten Informationen oben angezeigt werden. Zu den verfügbaren Informationen gehören:
- Datum und Uhrzeit der Generierung des Berichts.
- Datenbankzugriffsdetails, falls verfügbar. Datenbankzugriffe ohne Serviceanforderung und Datenbankzugriff mit Serviceanforderung werden in getrennten Abschnitten aufgelistet.
  Wenn im Aktivitätsbericht kein manueller Datenbankzugriff gemeldet wird, lautet der Bericht No SQL statements executed.
- Senden Sie den Bericht optional an eine angegebene E-Mail-Adresse.

So automatisieren Sie Audit und Compliance des Datenbankzugriffs:

Kopieren Sie eines der Skripte aus den folgenden Abschnitten in eine Datei, und speichern Sie es in Ihrem Dateisystem. Nennen Sie die Datei parseActivityReport.ps1 (für Windows siehe PowerShell-Skript (parseActivityReport.ps1)) oder parseActivityReport.sh (für Linux/UNIX siehe Bash Shell-Skript (parseActivityReport.sh)).

Nur Windows: Erstellen Sie eine Batchdatei namens parseActivityReport.bat, indem Sie das folgende Skript in eine Datei kopieren. Speichern Sie die Datei in dem Verzeichnis, in dem parseActivityReport.ps1 gespeichert ist.

@echo off
set paramRequiredMessage=Syntax: parseActivityReport.bat USERNAME PASSWORD/PASSWORD_FILE URL [REPORT_EMAIL_TO_ADDRESS]

if "%~1" == "" (
  echo User Name is missing.
  echo %paramRequiredMessage%
  exit /b 1
  )
if "%~2" == "" (
  echo Password or Password_File is missing.
  echo %paramRequiredMessage%
  exit /b 1
  )
if "%~3" == "" (
  echo URL is missing.
  echo %paramRequiredMessage%
  exit /b 1
  )

PowerShell.exe -File parseActivityReport.ps1 %*

Ändern Sie parseActivityReport.bat (Windows) bzw. parseActivityReport.sh (Linux/UNIX), um die Werte für die Parameter in der folgenden Tabelle festzulegen.

Tabelle 3-11 In Skripte einzuschließende Variablenwerte

Variable	Beschreibung
`epmuser`	Benutzername eines Serviceadministrators Beispiele: Windows: `set epmuser="jDoe"` Linux/UNIX: `epmuser="jDoe"`
`epmpassword`	Kennwort des Serviceadministrators oder Speicherort der verschlüsselten Kennwortdatei. Informationen zum Erstellen einer verschlüsselten Kennwortdatei finden Sie im Abschnitt zum Befehl `encrypt`. Wenn Ihr Kennwort Sonderzeichen enthält, finden Sie unter Sonderzeichen verarbeiten weitere Informationen. Beispiele: Windows: `set epmpassword = "Example"` Linux/UNIX: `epmpassword="Example"`
`epmurl`	Die URL der Oracle Fusion Cloud Enterprise Performance Management-Umgebung. Beispiele: Windows: `set epmurl="https://example.oraclecloud.com"` Linux/UNIX: `epmurl="https://example.oraclecloud.com"`
`report_email_to_address`	Optional, die E-Mail-Adresse, an die der Bericht gesendet werden soll. Der Bericht wird nur per E-Mail gesendet, wenn dieser Wert angegeben wurde. Beispiel: `john.doe@example.com`

Nur für parseActivityReport.sh: Stellen Sie sicher, dass die folgenden Werte für Ihr System richtig festgelegt sind:
- JAVA_HOME
- Speicherort von epmautomatescript.sh, indem Sie den Wert der Anweisung epmautomatescript aktualisieren
Planen Sie mithilfe eines im Betriebssystem verfügbaren Schedulers einmal täglich die Ausführung von parseActivityReport.bat (womit parseActivityReport.ps1 ausgeführt wird) oder parseActivityReport.sh. Informationen hierzu finden Sie unter Skriptausführung automatisieren.
