oracle 11.2版本.sysman/log下emdb.nohup文件偏大,如何解决？

参考文章

实验：

1、查看当前emctl status dbconsole为runing状态

2、关闭emctl stop dbconsole

3、删除/u01/app/oracle/product/11.2.0/db_1/gtone.localdomain_CQRCB/sysman/log目录下emdb.nohup文件

4、重新启动emctl start dbconsole

5、查看自动生成了emdb.nohup文件

 

论证emdb.nohup文件与emctl的相关性

1、通过fuser命令，查看

[root@gtone ~]# fuser  /u01/app/oracle/product/11.2.0/db_1/gtone.localdomain_CQRCB/sysman/log/emdb.nohup 
/u01/app/oracle/product/11.2.0/db_1/gtone.localdomain_CQRCB/sysman/log/emdb.nohup: 11733 11753 11763

2、通过ps -ef | grep oracle命令查看进程信息

[root@gtone ~]# ps -ef | grep oracle

 3、清除emdb.log文件，没有问题.
