第一次报错还有一个提示是：对EmbeddedLDAP.tran文件没有权限；
查找原因并解决：
首先对EmbeddedLDAP.tran文件没有权限，说明很有可能之前是用root用户启动过weblogic，导致权限更改；
解决：修改权限：
[root@cifi-BI ~]# cd /u01/app/oracle/product/epm/user_projects/domains/EPMSystem/servers/AdminServer/data/ldap/ldapfiles/
[root@cifi-BI ldapfiles]# chown -R oracle:oinstall EmbeddedLDAP.tran
重启测试：
[root@cifi-BI ldapfiles]# su oracle
[oracle@cifi-BI ldapfiles]$ cd /u01/app/oracle/product/epm/user_projects/domains/EPMSystem/bin/
[oracle@cifi-BI bin]$ ./startWebLogic.sh
依然报错；
备份并删除
/u01/app/oracle/product/epm/user_projects/domains/EPMSystem/servers/AdminServer/data下的ladp
然后重启：
[root@cifi-BI ldapfiles]# su oracle
[oracle@cifi-BI ldapfiles]$ cd /u01/app/oracle/product/epm/user_projects/domains/EPMSystem/bin/
[oracle@cifi-BI bin]$ ./startWebLogic.sh
可正常启动。
