• 10g异机恢复后EM无法启动故障处理一例


    之前在自己的測试环境上做了个异机恢复,原来的库上是配置过EM的,可是在恢复的库上去启动EM就报错了。以下看详细解决过程:
    PS:原主机名为zlm,恢复出来的主机名为bak

    [root@bak ~]# su - oracle
    [oracle@bak ~]$ emctl status dbconsole
    TZ set to PRC
    OC4J Configuration issue. /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_bak_ora10g not found. 
    [oracle@bak ~]$ cd /u01/app/oracle/product/10.2.0/db_1/oc4j/j2ee/
    [oracle@bak j2ee]$ ll

    -rw-r--r--  1 oracle oinstall  256 Aug 22 16:42 deploy_db.ini

    drwxr-x---  7 oracle oinstall 4096 Aug 25 11:25 OC4J_DBConsole_zlm_ora10g

    既然提示文件找不到。非常显然是由于主机名变更的缘故,那么把名字变一下,用mv命令

    [oracle@bak j2ee]$ mv -r OC4J_DBConsole_zlm_ora10g/ OC4J_DBConsole_bak_ora10g/
    [oracle@bak j2ee]$ ll

    发现也是一堆报错,当中有一段是这种,显示地主机命名还是之前旧的信息(原来的主机名为zlm,如今的为bak):

    看来只又一次配置一下EM资料库是不行的,须要重建一下(先删除,后创建)

    [oracle@bak log]$ emca -repos recreate 
    shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
    Error occurred during initialization of VM
    java.lang.Error: Properties init: Could not determine current working directory.

    错误表示 getcwd 命令无法定位到当前工作文件夹。一般来说是由于 cd 到了某个文件夹之后又rm 了这个文件夹
    这时去运行某些命令就会报 getcwd 错误​,仅仅须要 cd 到不论什么一个实际存在的文件夹下在运行命令就可以。
    出现这样的现象的原因还有,当前用户没有当前文件夹的可运行权限。如没有正确设置ORACLE_SID环境变量。我这里属于这样的情况。


    [oracle@bak log]$ set ORACLE_SID=ora10g
    [oracle@bak log]$ emca -repos recreate

    能够看到3个successfully,重建后并把em配置也又一次刷了一遍

    [oracle@bak log]$ emctl status dbconsole
    TZ set to PRC

    http://bak:1158/em/console/aboutApplication    --重建EM资料库后。如今的主机名已经更正为“bak”了
    Oracle Enterprise Manager 10g is not running.

    再次又一次启动EM

    [oracle@bak log]$ emctl start dbconsole

    通过重建EM后,就能够用web浏览器登陆EM管理界面了,新的url为:http://bak:1158/em

    总结:

    遇到各种原因造成的EM无法登陆的问题,一般是由于旧的EM资料库配置有问题,或者是由于改变了主机或IP地址所造成,能够使用emca -repos recreate重建,就能直接解决这个问题,只通过emca -config dbconsole db来又一次配置是不够彻底的,由于还会有之前错误信息的残留,除了这几个命令外,emca还有非常多其它參数。能够通过emca --help查看,这里就不列举了。
