一、启动报错
<BEA-141281> <unable to get file lock, will retry …>
解决办法
一.删掉Domain下的*.lok文件
1. 删除edit.lok
进入到domain_home下：
cd /u01/Oracle/Middleware/user_projects/domains/idm_domain
将edit.lok文件删掉
rm edit.lok
2.删除config.lok
进入到domain_home/config下：
cd /u01/Oracle/Middleware/user_projects/domains/idm_domain/config/
将config.lok文件删掉
rm config.lok
3.删除AdminServer.lok
cd /u01/Oracle/Middleware/user_projects/domains/idm_domain/servers/AdminServer/tmp
rm AdminServer.lok
4.删除EmbeddedLDAP.lok
/u01/Oracle/Middleware/user_projects/domains/idm_domain/servers/AdminServer/data/ldap/ldapfiles
rm EmbeddedLDAP.lok
二.删掉Domain下的*.DAT文件：
进入到domain_home当中
cd /u01/Oracle/Middleware/user_projects/domains/idm_domain
找到文件被删掉
[oracle@idm idm_domain]$ find servers/ -name "*.DAT"
servers/AdminServer/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
servers/AdminServer/data/store/default/_WLS_ADMINSERVER000000.DAT
二、继续报错
<BEA-280061> <The persistent store “_WLS_AdminServer” could not be deployed: weblogic.store.PersistentStoreException: [Store:280105]The persistent file store “_WLS_AdminServer” cannot open file _WLS_ADMINSERVER000000.DAT. weblogic.store.PersistentStoreException: [Store:280105]The persistent file store “_WLS_AdminServer” cannot open file _WLS_ADMINSERVER000000.DAT. at weblogic.store.io.file.Heap.open(Heap.java:325)
解决办法：因为下面两个文件没有删除，删除掉重启就好了
servers/AdminServer/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
servers/AdminServer/data/store/default/_WLS_ADMINSERVER000000.DAT
网上找的解决办法：
find . -name “*.DAT” -print -exec rm {} \;
find . -name “*.lok” -print -exec rm {} \;
For Admin server
$DOMAIN_HOME/servers/<server name>/tmp/Adminserver.lok
$DOMAIN_HOME/servers/<server name>/data/ldap/ldapfiles/Embedded.lok
$DOMAIN_HOME/servers/<server name>/data/store/default/_WLS_ADMINSERVER000000.DAT
$DOMAIN_HOME/servers/<server name>/data/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
For Managed servers
$DOMAIN_HOME/servers/<server name>/tmp/<servername>.lok
$DOMAIN_HOME/servers/<server name>/data/ldap/ldapfiles/Embedded.lok
$DOMAIN_HOME/servers/<server name>/data/ldap/store/default/_WLS_<servername>000000.DAT
$DOMAIN_HOME/servers/<server name>/data/ldap/store/diagnostics/WLS_DIAGNOSTICS000000.DAT
三、启动到一半报错，貌似端口被占用
<Error> <Server> <BIEE> <AdminServer> <DynamicListenThread[Default[1]]> <<WLS Kernel>> <> <11d1def534ea1be0:6838a223:14bcf28f0c4:-8000-000000000000000c> <1425109784345> <BEA-002606> <Unable to create a server socket for listening on channel "Default[1]". The address fe80:0:0:0:ba2a:72ff:fed4:83a1 might be incorrect or another process is using port 7001: java.Net.BindException: Address already in use.>
解决办法：执行ps -ef|grep leg，发现有一个weblogic在执行(带有jdk比较长的那个)占用了端口,杀掉,kill -9 加进程id(第二个数字)，重新启动weblogic即可。
