將應用程式快照備份至電腦

本案例說明如何自動化備份每日服務維護期間建立的快照到本機電腦的程序。

  • 下載維護期間建立的應用程式快照 (Artifact Snapshot)
  • 透過附加時間戳記重新命名下載的快照
  • 視需要透過刪除最舊的備份以刪除最舊的備份

Note:

  • 此指令碼不得用於備份 Narrative Reporting
  • 若要針對您的用途改寫此指令碼，請視需要修改執行時期參數 (url、user、password 和 NumberOfBackups) 的值。

請參閱自動執行指令碼以取得使用 Windows 工作排程器排程執行指令碼的相關資訊。

Windows 範例指令碼

建立包含類似下列內容之指令碼的批次 (.bat) 或 Shell (.sh) 檔案以自動執行快照下載。

@echo off
rem Sample script to download and maintain 10 maintenance backups
rem Update the following  parameters

SET url=https://example.oraclecloud.com
SET user=ServiceAdmin
SET password=Example.epw
SET SnapshotName="Artifact Snapshot"
SET NumberOfBackups=10

rem EPM Automate commands
call epmautomate login %user% %password% %url% 
     IF %ERRORLEVEL% NEQ 0 goto :ERROR
       call epmautomate downloadfile %SnapshotName%
     IF %ERRORLEVEL% NEQ 0 goto :ERROR
       call epmautomate logout
     IF %ERRORLEVEL% NEQ 0 goto :ERROR

rem Rename downloaded Artifact Snapshot, keep the last 10 backups
Set Timestamp=%date:~4,2%_%date:~7,2%_%date:~10,2%%
Set Second=%time:~0,2%%time:~3,2%
ren %SnapshotName%.zip %SnapshotName%_%Timestamp%_%Second%.zip

SET Count=0
FOR %%A IN (%SnapshotName%*.*) DO SET /A Count += 1
IF %Count% gtr %NumberOfBackups% FOR %%A IN (%SnapshotName%*.*) DO del "%%A" && GOTO EOF
:EOF

echo Scheduled Task Completed successfully
exit /b %errorlevel%
:ERROR
echo Failed with error #%errorlevel%.
exit /b %errorlevel%

Linux/UNIX 範例指令碼

建立 shell (.sh) 檔案，其中包含類似以下內容的指令碼，以自動執行快照下載。如果密碼包含特殊字元，請參閱處理特殊字元。

#!/bin/sh
# Sample script to download and maintain 10 maintenance backups
# Update the following seven parameters

url=https://example.oraclecloud.com
user=serviceAdmin
password=/home/user1/epmautomate/bin/example.epw
snapshotname="Artifact Snapshot"
numberofbackups=10
epmautomatescript=/home/user1/epmautomate/bin/epmautomate.sh
javahome=/home/user1/jdk1.8.0_191/

export JAVA_HOME=${javahome}

printResult()
    {
    op="$1"
    opoutput="$2"
    returncode="$3"

    if [ "${returncode}" -ne 0 ]
    then
        echo "Command failed. Error code: ${returncode}. ${opoutput}"
    else 
        echo "${opoutput}"
    fi
}

processCommand()
{
    op="$1"
    date=`date`

    echo "Running ${epmautomatescript} ${op}"
    operationoutput=`eval "$epmautomatescript $op"`
    printResult "$op" "$operationoutput" "$?"
}

op="login ${user} ${password} ${url}"
processCommand "${op}"

op="downloadfile \"${snapshotname}\""
processCommand "${op}"

op="logout"
processCommand "${op}"

# Renames the downloaded artifacts, keeps the last 10 backups
timestamp=`date +%m_%d_%Y_%I%M`
mv "${snapshotname}.zip" "${snapshotname}_${timestamp}.zip"

((numberofbackups+=1))
ls -tp ${snapshotname}*.zip | grep -v '/$' | tail -n +${numberofbackups} | xargs -d '\n' -r rm --
