Oracle Application Server修改主机名或者域名时, 除了修改DNS之外还需要更新Oracle Application Server的相关配置。修改Oracle Infrastructure Server的主机名或域名情况类似。

        具体可参照Oracle的相关文档。

        http://download.oracle.com/docs/cd/B14099_19/core.1012/b13995/host.htm#CHDGAIFH

        下面针对Linux环境下安装middle-tier instance的Application Server例举一下主要步骤，整个过程中数据库、OracleAS基础应用数据库、Oracle基础应用服务都处于启动状态。

        1>检测环境变量:

echo $ORACLE_HOME

//Set to the full path of the installation's Oracle home, /app/oraias/OraHome_1

echo $LD_LIBRARY_PATH

//$ORACLE_HOME/lib32

echo $LD_LIBRARY_PATH_64

//$ORACLE_HOME/lib

echo $PATH

//contains $ORACLE_HOME/bin,$ORACLE_HOME/dcm/bin,$ORACLE_HOME/opmn/bin

        2>将Instance从Farm中移除

如果是属于OracleAS File-Based Farm, 使用如下命令移除Instance

ORACLE_HOME/dcm/bin/dcmctl leavefarm

If the host contains a J2EE and Web Cache instance that is part of an OracleAS File-Based Farm that uses a repository on another host or an OracleAS Database-Based Farm, remove the instance from the farm:         

ORACLE_HOME/dcm/bin/dcmctl leavefarm 

        3>停止Application Server的控制台和相关服务进程。命令如下：

        停止控制台服务: ORACLE_HOME/bin/emctl stop iasconsole
        停止相关服务进程: ORACLE_HOME/opmn/bin/opmnctl stopall

        确保该middle tire所使用的OID(Oracle Internet Directory)服务处于开启状态。

        4>修改主机名、域名或者ip地址。

                修改域名需要修改以下文件中的配置:

                /etc/inet/hosts

                /etc/inet/ipnodes

                修改主机名还需要修改以下文件:

/etc/nodename

/etc/hostname.*

修改完后重启机器。重启后检查more /etc/hosts

        5>运行chgiphost命令。

        首先设置log的级别。修改文件$ORACLE_HOME/chgip/config/chgip.log.properties，将参数java.util.logging.ConsoleHandler.level设置为CONFIG。

                使用命令

grep java.util.logging.ConsoleHandler.level $ORACLE_HOME/chgip/config/chgip.log.properties

                确认修改完毕。

                cd $ORACLE_HOME/chgip/scripts
                ./chgiphost.sh –mid

                该命令运行过程中根据提示，依次

1.       输入新的hostname.domainname

2.       输入新的hostname.domainname

3.       输入新的ip地址

4.       输入旧的ip地址，

5.       输入OIDAdmin的密码。即Oracle Internet Directory的cn=orcladmin用户的密码。

        more $ORACLE_HOME/chgip/log, 查看日志文件是否修改成功。日志文件位于$ORACLE_HOME/chgip/log。

       chgiphost命令实际是在$OACLE_HOME/chgip/config/hostname.lst列出的文件中执行替换工作。

        6>启动Application Server相关服务和控制台。

        ORACLE_HOME/opmn/bin/opmnctl startall
        ORACLE_HOME/bin/emctl start iasconsole

        7>将Instance添加到Farm中

If the host contained an instance that stored the file-based repository used by an OracleAS File-Based farm:

ORACLE_HOME/dcm/bin/dcmctl getRepositoryID

ORACLE_HOME/dcm/bin/dcmctl joinfarm -r repository_ID

If you removed any J2EE and Web Cache instances from an OracleAS File-Based Farm

ORACLE_HOME/dcm/bin/dcmctl joinfarm -r repository_ID

If you removed any J2EE and Web Cache instances from an OracleAS Database-Based Farm at the beginning of this procedure

ORACLE_HOME/dcm/bin/dcmctl joinfarm

耐心等待该步骤完成后，需要再次启动服务:

$ORACLE_HOME/opmn/bin/opmnctl startall

        8>更新OracleAS Portal, OracleAS Wireless, OracleAS Single Sign-On, 和Oracle Ultra Search

                Refer: http://download.oracle.com/docs/cd/B14099_19/core.1012/b13995/host.htm#CIHHADCE

1.       Update OracleAS Portal with the new OracleAS Wireless service URL.

Refer: http://download.oracle.com/docs/cd/B14099_19/portal.1012/b14037/cg_basic.htm#i1050271

2.       Update OracleAS Single Sign-On server with the new OracleAS Wireless SSO Partner URL.

ORACLE_HOME/wireless/bin/reRegisterSSO.sh

根据提示进行。

3.       Re-register OracleAS Portal as an Oracle Ultra Search Content Source.

Refer: http://download.oracle.com/docs/cd/B14099_19/portal.1012/b14037/cg_srch.htm#POCFG404

        9>手动修改文件中的hostname. 这些文件与配置无关。

       位于$ORACLE_HOME/Apache/Apache/htdocs目录下面。

index.html.de
  index.html.es_ES
  index.html.fr
  index.html.it
  index.html.ja
  index.html.ko
  index.html.pt_BR
  index.html.zh_CN
  index.html.zh_TW

                运行如下命令：

                cd $ORACLE_HOME/Apache/Apache/htdocs

grep old_hostname.domainname index.html.*

for indexHtml in index.html.*

do

cat $indexHtml | sed 's/old_hostname.domainname/new_hostname.domainname/g' > tmp.txt

mv -f tmp.txt $indexHtml

done
