一、Console修改密碼後，掛載的服務無法重啟【解決辦法】

1、開啟 weblogic 控制檯，安全領域 --> myrealm --> 使用者和組，將會看到 weblogic 使用者，可以直接刪除，也可以點選 weblogic 進行修改，這裡儲存後立即生效。

2、這時重啟 weblogic 控制檯會報錯，通過 cmd 可以看到如下提示資訊。

<2015-6-27 下午01時02分27秒 CST> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FAILED>  
<2015-6-27 下午01時02分27秒 CST> <Error> <WebLogicServer> <BEA-000383> <A critical service failed. The server will shut itself down>  
<2015-6-27 下午01時02分27秒 CST> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FORCE_SHUTTING_DOWN>  
#這是因為啟動服務用的使用者名稱密碼和登入的是同一個，而啟動時所讀取的boot.properties檔案中的密碼還是舊的。
 

3、所以需要去修改 DOMAIN_HOME/servers/server_name/security/boot.properties 檔案，把 username 和 password 改為明文的新密碼，各 server 都得改。

4、然後重啟受管伺服器和管理伺服器即可，啟動成功後 boot.properties 檔案內容已改成了密文。

二. weblogic console登入密碼遺忘【解決方法】

1、首先進入 weblogic 安裝目錄，備份三個檔案：boot.properties，DefaultAuthenticatorInit.ldift，DefaultAuthenticatormyrealmInit.initialized。

2、重新生成一個新的 DefaultAuthenticatorInit.ldift 檔案。具體操作為：

#找到 weblogic.jar 路徑

#在 %DOMAIN_HOME%/security 下執行如下命令：
java -classpath /data/bea/weblogic11/wlserver_10.3/server/lib/weblogic.jar weblogic.security.utils.AdminAccount weblogic weblogic123 .

#其中jar可以是相對路徑，也可以是絕對路徑；weblogic.security.utils.AdminAccount固定格式；weblogic 是使用者名稱，weblogic123 是密碼，最後加一個空格 和一個點.  最後一個.不要忘了）

#執行完會在當前路徑下面生成一個新的 DefaultAuthenticatorInit.ldift 檔案。
 

3、到 XX/servers/AdminServer/security 路徑下新建一個 boot.properties 檔案，並寫入：username=weblogic password=weblogic123儲存。

4、刪除 XX/servers/AdminServer/data/ 下面的ldap資料夾，

5、重新啟動 weblogic，啟動成功，即可刪除備份的 boot.properties，DefaultAuthenticatorInit.ldift，DefaultAuthenticatormyrealmInit.initialized 三個檔案。

三. 問題補充說明

帳號/密碼修改後啟動 weblogic 失敗，我遇上兩種情況. 錯誤差異都是從:<Notice> <Security> <BEA-090082> <Security initializing using security realm myrealm.>語句之後開始體現的.

3.1. 當通過./startManagedWebLogic.sh 啟動時,手動輸入錯誤的密碼,列印日誌如下:

假設現在帳號/密碼已從 weblogic/weblogic123 改成 weblogic/weblogic798 ,此時故意輸錯密碼成 wbwbwb

如果是這個問題，用正確的使用者名稱，密碼再次啟動就可以了

3.2. 誤以為 boot.properties 配置錯誤,其實是 NodeManager.sh 密碼問題

該錯誤一般在使用 NodeManager.sh 啟動被管理 Server 時會報.

原因分析：
其實這個時候我們已修改了 AdminServer 管理控制檯密碼,但是 NodeManager 記住的還是舊密碼。而用 NodeManager 啟動被管理 Server 時,是不需要讀取 boot.properties 的,只有在用 ./startManagerWeblogic.sh 時才需要用到 boot.properties 帳號密碼.

解決思路：
1、需要進入wlst(weblogic script tool), 讓 NodeManager 重新抓取 AdminServer 的配置

#以下命令,請一句一句執行.
cd /data/weblogic/wls/wlserver_10.3/common/bin

sh ./wlst.sh 

connect('weblogic','password123','t3://ip:7004')

nmEnroll('/data/weblogic/servers/m95/')

disconnect()

exit()

2、執行完畢,重啟NodeManager

3、控制檯啟動被管理Server下.

注意：這裡如果還是報一樣錯誤.....沒關係,進入到被管理server目錄下,清下快取

cd /oracle/esbapp/bea/weblogic11/user_projects/domains/esb_domain/servers/vhlSearch/
rm -rf tmp
rm -rf stage/
rm -rf cache/
rm -rf data
