一、Console修改密码后，挂载的服务无法重启【解决办法】
1、打开 weblogic 控制台，安全领域 --> myrealm --> 用户和组，将会看到 weblogic 用户，可以直接删除，也可以点击 weblogic 进行修改，这里保存后立即生效。
2、这时重启 weblogic 控制台会报错，通过 cmd 可以看到如下提示信息。
<2015-6-27 下午01时02分27秒 CST> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FAILED>
<2015-6-27 下午01时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时02分27秒 CST> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to FORCE_SHUTTING_DOWN>
#这是因为启动服务用的用户名密码和登录的是同一个，而启动时所读取的boot.properties文件中的密码还是旧的。
3、所以需要去修改 DOMAIN_HOME/servers/server_name/security/boot.properties 文件，把 username 和 password 改为明文的新密码，各 server 都得改。
4、然后重启受管服务器和管理服务器即可，启动成功后 boot.properties 文件内容已改成了密文。
二. weblogic console登录密码遗忘【解决方法】
1、首先进入 weblogic 安装目录，备份三个文件：boot.properties，DefaultAuthenticatorInit.ldift，DefaultAuthenticatormyrealmInit.initialized。
2、重新生成一个新的 DefaultAuthenticatorInit.ldift 文件。具体操作为：
#找到 weblogic.jar 路径
#在 %DOMAIN_HOME%/security 下执行如下命令：
java -classpath /data/bea/weblogic11/wlserver_10.3/server/lib/weblogic.jar weblogic.security.utils.AdminAccount weblogic weblogic123 .
#其中jar可以是相对路径，也可以是绝对路径；weblogic.security.utils.AdminAccount固定格式；weblogic 是用户名，weblogic123 是密码，最后加一个空格 和一个点. 最后一个.不要忘了）
#执行完会在当前路径下面生成一个新的 DefaultAuthenticatorInit.ldift 文件。
3、到 XX/servers/AdminServer/security 路径下新建一个 boot.properties 文件，并写入：username=weblogic password=weblogic123保存。
4、删除 XX/servers/AdminServer/data/ 下面的ldap文件夹，
5、重新启动 weblogic，启动成功，即可删除备份的 boot.properties，DefaultAuthenticatorInit.ldift，DefaultAuthenticatormyrealmInit.initialized 三个文件。
三. 问题补充说明
帐号/密码修改后启动 weblogic 失败，我遇上两种情况. 错误差异都是从:<Notice> <Security> <BEA-090082> <Security initializing using security realm myrealm.>语句之后开始体现的.
3.1. 当通过./startManagedWebLogic.sh 启动时,手动输入错误的密码,打印日志如下:
假设现在帐号/密码已从 weblogic/weblogic123 改成 weblogic/weblogic798 ,此时故意输错密码成 wbwbwb

如果是这个问题，用正确的用户名，密码再次启动就可以了
3.2. 误以为 boot.properties 配置错误,其实是 NodeManager.sh 密码问题
该错误一般在使用 NodeManager.sh 启动被管理 Server 时会报.

原因分析：
其实这个时候我们已修改了 AdminServer 管理控制台密码,但是 NodeManager 记住的还是旧密码。而用 NodeManager 启动被管理 Server 时,是不需要读取 boot.properties 的,只有在用 ./startManagerWeblogic.sh 时才需要用到 boot.properties 帐号密码.
解决思路：
1、需要进入wlst(weblogic script tool), 让 NodeManager 重新抓取 AdminServer 的配置
#以下命令,请一句一句执行.
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、执行完毕,重启NodeManager
3、控制台启动被管理Server下.
注意：这里如果还是报一样错误.....没关系,进入到被管理server目录下,清下缓存
cd /oracle/esbapp/bea/weblogic11/user_projects/domains/esb_domain/servers/vhlSearch/
rm -rf tmp
rm -rf stage/
rm -rf cache/
rm -rf data
