重启WebLogic应用，使用tail -f yx.log查看日志，发现server启动不了：

<Jul 24, 2014 7:23:03 AM GMT> <Notice> <Log Management> <BEA-170019> <The server log file /home/weblogic/bea/user_projects/domains/base_domain/servers/AdminServer/logs/AdminServer.log is opened. All server side log events will be written to this file.>

如果遇到以上错误，请从以下两个方面入手：

1，查看磁盘空间是否满。

2，如果磁盘空间是OK的，删除/servers/AdminServer/data/ldap/conf/replicas.prop

使用df -h 查看磁盘空间

[root@masterbei79 ~]# df -h

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1              49G   48G     0 100% /

tmpfs                  16G   88K   16G   1% /dev/shm

/dev/sda3             223G  2.4G  209G   2% /temp-hadoop

cm_processes           16G  296K   16G   1% /var/run/cloudera-scm-agent/process

根目录下空间确实使用完。

对磁盘空间进行释放后，

[root@masterbei79 conf]# df -h

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1              49G   21G   25G  46% /

tmpfs                  16G   88K   16G   1% /dev/shm

/dev/sda3             223G  2.4G  209G   2% /temp-hadoop

cm_processes           16G  296K   16G   1% /var/run/cloudera-scm-agent/process

启动WebLogic server，发现日志还是报同样错误，网上还有一个中方法：

要删除ldap/conf中的 replicas.prop 或者将文件清空,添加 这一行 

replica.num=0

尝试了下

root@masterbei79 conf]# pwd

/home/weblogic/bea/user_projects/domains/base_domain/servers/AdminServer/data/ldap/conf

[root@masterbei79 conf]# cat replicas.prop

replica.num=0

在重启WebLogic server  成功：
