Oracle数据库日常管理_项目现场篇

修改：2010/2/8 A. 查看所有的实例及其后台进程是否正常

确认所有的instance工作正常，登陆到所有的数据库或instance上，检测oracle后台进程GDDB4-/export/home/oracle> env | grep SID

ORACLE_SID=UWNMS3

GDDB4-/export/home/oracle> ps -ef|grep UWNMS3 | grep -v grep | grep ora

B．检查文件系统的使用情况

如果文件系统的剩余空间小于10％，则需要删除不必要的文件以释放空间。

GDDB4-/export/home/oracle> df -h

Filesystem size used avail capacity Mounted on

/dev/md/dsk/d0 20G 17G 3.1G 85% /

/proc 0K 0K 0K 0% /proc

mnttab 0K 0K 0K 0% /etc/mnttab

fd 0K 0K 0K 0% /dev/fd

swap 85G 192K 85G 1% /var/run

dmpfs 85G 0K 85G 0% /dev/vx/dmp

dmpfs 85G 0K 85G 0% /dev/vx/rdmp

swap 85G 213M 85G 1% /tmp

/dev/vx/dsk/data10dg/Ora_File_Vol01

394G 292G 98G 75% /data05

/dev/vx/dsk/data1dg/vola0131

443G 156G 283G 36% /archivelog

注意：需要特别关注根目录，数据库软件和数据库备份所在目录的剩余空间情况！备注：数据库运行日志的及时清除

1). 可清除bdump,cdump,udump下的相关日志

$ cd bdump

$ ls -l

total 174

$ cp /dev/null

$ rm *.trc

$ cd ../cdump

$ ls -l

2). 可清除oracle的监听日志

$ cd $ORACLE_HOME/network/log
