metalink上说：
Changes
A change has taken place at the network level since you last started this OC4J instance
Cause
The OC4J lock files contains the IP adress, after the ip adress change the lock files includes the wrong Ip adress which caused the OJ4J to fail
Solution
1 - Be sure to have a valid Backup
2 - open a new shell and set your apps environment
3 - cd <ADMIN_SCRIPTS_HOME>
4 - adopmnctl.sh stop or adopmnctl.cmd stop for windows
5 - check if it is really down: ps -ef | grep <USER> grep opm for windows check if all java.exe processes are gone.
6 - delete the following:
rm -fr $INST_TOP/ora/10.1.3/j2ee/oacore/persistence/*
rm -fr $INST_TOP/ora/10.1.3/j2ee/oafm/persistence/*
rm -fr $INST_TOP/ora/10.1.3/j2ee/forms/persistence/*
for windows
rm -fr %INST_TOP%\ora\10.1.3\j2ee\oacore\persistence\*
rm -fr %INST_TOP%\ora\10.1.3\j2ee\oafm\persistence\*
rm -fr %INST_TOP%\ora\10.1.3\j2ee\forms\persistence\*
Use use the explorer validate if they are deleted for windows.
6 - execute autoconfig at the Application Tier
7 - start all Applications Services
8 - check if the issue has been resolved: adapcctl.sh status or for windows adapcctl.cmd status

查了MetaLink和ITpub，问题终于解决了（不过还不是特别明白）
原因:OC4J 的LOCK文件内容包含系统的IP,当IP改变后LOCK文件中的IP是错误的,从而导致OC4J失败.
解决:
1.将以下三个文件夹下所有文件删除
$INST_TOP/ora/10.1.3/j2ee/forms/persistence/
$INST_TOP/ora/10.1.3/j2ee/oafm/persistence/
$INST_TOP/ora/10.1.3/j2ee/oacore/persistence/
2.执行adautocfg.sh
3.重新启动，启动的顺序：
adopmnctl.sh
adapcctl.sh
adoacorectl.sh
adformsctl.sh
adoafmctl.sh
adalnctl.sh
adcmctl.sh apps/apps
jtffmctl.sh
到adapcctl.sh
adoafmctl.sh 时，还是报错
跳过，继续执行下面的
执行完其他的之后，再执行adapcctl.sh和adoafmctl.sh
都不报错了，EBS也可以进了。
据查，如果要更改ebs的域名
修改机器名后，要再修改$CONTEXT_FILE，目录如下：
/d01/appl/PROD01/inst/apps/PROD01_ebs12test/appl/admin/PROD01_ebs12test.xml
