linux下手動刪除資料庫執行個體

 

 linux下手動刪除資料庫執行個體，直接刪除相應的目錄就可以了，不多說了....

1. $ORACLE_HOME/dbs/
[oracle9@frogger dbs]$ pwd
/u01/app/oracle/product/9.2.0.1/dbs
[oracle9@frogger dbs]$ rm inittest02.ora
[oracle9@frogger dbs]$ rm orapwdtest02

2. $ORACLE_BASE/oradata/SID
[oracle9@frogger oradata]$ ls
default_demo01.dbf  default_demo99.dbf  devdb02  duke1  test01  test01_bak  test02  testdk  testqa
[oracle9@frogger oradata]$ ps -ef|grep smon
oracle9   7162     1  0  2008 ?        00:04:30 ora_smon_duke
oracle9   3313     1  0  2008 ?        00:02:30 ora_smon_testdk
oracle9   4386     1  0 Apr05 ?        00:00:07 ora_smon_test01
oracle9   4620     1  0 Apr05 ?        00:00:05 ora_smon_dvdsame
oracle9  12307  4426  0 22:53 pts/3    00:00:00 grep smon
[oracle9@frogger oradata]$ rm -rf test02
[oracle9@frogger oradata]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      455G  381G   51G  89% /
/dev/sda1              99M   15M   80M  16% /boot
none                 1004M     0 1004M   0% /dev/shm
nfs-vip.certificatesnow.com:/u07
                      455G  230G  202G  54% /u07
[oracle9@frogger oradata]$ ls
default_demo01.dbf  default_demo99.dbf  devdb02  duke1  test01  test01_bak  testdk  testqa

3. 刪除log檔案
[oracle9@frogger admin]$ ls
devdb02  duke1  test01  test02  testdk  testqa
[oracle9@frogger admin]$ pwd
/u01/app/oracle/admin
[oracle9@frogger admin]$ cd test02
[oracle9@frogger test02]$ ls
bdump  cdump  create  pfile  udump
[oracle9@frogger test02]$ cd ..
[oracle9@frogger admin]$ ls
devdb02  duke1  test01  test02  testdk  testqa
[oracle9@frogger admin]$ rm -rf test02
[oracle9@frogger admin]$ ls
devdb02  duke1  test01  testdk  testqa
[oracle9@frogger admin]$

4. 如果是用dbca建立的執行個體，則還要刪除/etc/oratab檔案中的執行個體資訊，就一行。 刪除就ok了。
/etc/oratab 運行root.sh產生的,中每一行代表一個ORACLE 執行個體,不允許有相同的名字，對已經存在的資料庫會提示是否升級等,安
裝建立資料庫的時候會去檢查這個檔案是否存在和並檢查檔案中的內容,在運行dbstart 時會檢查這個檔案，如果是Y就啟動它，是N
就不管它。
[oracle9@frogger admin]$ cd /etc
[oracle9@frogger etc]$ more oratab
#
# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively.  The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.

test02:/u01/app/oracle/product/9.2.0.1:N
[oracle9@frogger etc]$
