Oracle10g R2 EMCA

   在 10g 中,我们可能会经常遇到OEM不能正常使用的问题,但导致问题的原因不尽相同,最后绝大多数问题可以通过emca 这个命令来解决,详细的说明可以查看联机帮助,下面给出一些常用的命令及实例步骤.

1.创建repository
emca -repos create
2.创建DBconsole
emca -config dbcontrol db
3.重建
emca -config dbcontrol db -repos recreate
4.删除repository
emca -repos drop

isqlplusctl stop|start
emctl start|stop dbconsole

重建EM

先删除资料档案库
  emca -deconfig dbcontrol db -repos drop
手工删除em资料库的方法，不能漏掉，否则创建时会报错
  drop user sysman cascade;
  drop user mgmt_view cascade;
  drop role mgmt_user;
然后
  emca -repos recreate
$ emca -repos create
