1、shutdown normal
正常方式關(guān)閉數(shù)據(jù)庫。
2、shutdown immediate
立即方式關(guān)閉數(shù)據(jù)庫。
在SVRMGRL中執(zhí)行shutdown immediate,數(shù)據(jù)庫并不立即關(guān)閉,
而是在Oracle執(zhí)行某些清除工作后才關(guān)閉(終止會話、釋放會話資源),
當(dāng)使用shutdown不能關(guān)閉數(shù)據(jù)庫時,shutdown immediate可以完成數(shù)據(jù)庫關(guān)閉的操作。
3、shutdown abort
直接關(guān)閉數(shù)據(jù)庫,正在訪問數(shù)據(jù)庫的會話會被突然終止,
如果數(shù)據(jù)庫中有大量操作正在執(zhí)行,這時執(zhí)行shutdown abort后,重新啟動數(shù)據(jù)庫需要很長時間
--------------------------------------------------------
shutdown abort 的時候,跟kill 進程是一樣的效果
數(shù)據(jù)庫立即關(guān)閉,這個時候文件狀態(tài)可能不一致
因為正常關(guān)閉數(shù)據(jù)庫會同步校驗各文件,使得重新啟動的時候文件時間點一致并且不用進行崩潰恢復(fù)
若檢查點信息一致,則做崩潰恢復(fù)
若檢查點信息不一致(正好在更新文件頭)則需要做介質(zhì)恢復(fù)
這些問題都好處理,最怕的問題是這個時候系統(tǒng)有大量IO,結(jié)果這樣造成寫的突然中斷,碰巧造成文件塊的邏輯壞塊,那麻煩比較大一些,尤其是系統(tǒng)表空間的block損壞
雖然shutdown abort 出錯的幾率很小,1000個人可能只有一個人碰到,但是我們還是要小心。
正確的處理流程是,shutdown immediate ,若數(shù)據(jù)庫遲遲不能down下來,在os上觀察IO狀況,幾乎沒有io的時候,另開一窗口shutdown abort ,幾乎不會出問題了
--------------------------------------------------------
http://www.itpub.net/showthread.php?threadid=180315&pagenumber=
先用IMMEDIATE來DOWN,實在不行了,看一下數(shù)據(jù)庫文件上沒IO了,再用ABORT
------------------------------------------------------------------------------
你可以嘗試先在系統(tǒng)級殺掉非后臺Oracle進程,在連接shutdown immediate就安全多了
在Oracle8i里,當(dāng)數(shù)據(jù)庫失去響應(yīng)以后,你在操作系統(tǒng)上殺掉用戶進程后,一般數(shù)據(jù)庫就可以恢復(fù)正常了
-------------------------------------------------------------------------------
先 shutdown immediate 應(yīng)該是首選
然后不行再重新shutdown abort
其實起不來也是因為os的緣故,在文件正在寫的時候出現(xiàn)問題導(dǎo)致文件不一致或者損壞……

在給mysql數(shù)據(jù)庫備份時,報錯:mysqldump: Got error: 145: Table './jxzhtopenfire/ofoffline' is marked as crashed and should be repaired when using LOCK TABLES。
如上錯誤的解決方法如下:
1、進入數(shù)據(jù)庫對該表進行檢測:
mysql> check tables ofoffline;
+-------------------------+-------+----------+-------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+-------------------------+-------+----------+-------------------------------------------------------+
| jxzhtopenfire.ofoffline | check | warning | Table is marked as crashed |
| jxzhtopenfire.ofoffline | check | warning | 1 client is using or hasn't closed the table properly |
| jxzhtopenfire.ofoffline | check | error | Record at pos: 1175720 is not remove-marked |
| jxzhtopenfire.ofoffline | check | error | record delete-link-chain corrupted |
| jxzhtopenfire.ofoffline | check | error | Corrupt |
+-------------------------+-------+----------+-------------------------------------------------------+
5 rows in set
2、使用repair解決方法:
mysql> repair table ofoffline;
+-------------------------+--------+----------+------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+-------------------------+--------+----------+------------------------------------------+
| jxzhtopenfire.ofoffline | repair | warning | Number of rows changed from 2349 to 2451 |
| jxzhtopenfire.ofoffline | repair | status | OK |
+-------------------------+--------+----------+------------------------------------------+
再次進行dump備份就可以了。
備份mysql數(shù)據(jù)庫時報錯:mysqldump: Got error: 145: Table './jxzhtopenfire/ofoffline' is marked as crashed and should be repaired when using LOCK TABLES。
這樣的錯誤。
搜索了一下,發(fā)現(xiàn)只要在mysqldump的時候加上--lock-tables=false就可以解決問題。
mysqldump -u root -pMyPassword DbName --lock-tables=false > data.sql

oracle9i在進行數(shù)據(jù)庫全庫備份時出現(xiàn)如下錯誤:
Connected to: Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.8.0 - Production
Export done in ZHS16GBK character set and AL16UTF16 NCHAR character set
About to export the entire database ...
. exporting tablespace definitions
EXP-00008: ORACLE error 1187 encountered
ORA-01187: cannot read from file 201 because it failed verification tests
ORA-01110: data file 201: '/opt/ora9/product/oradata/NTDB/temp1.dbf'
EXP-00000: Export terminated unsuccessfully
從上面的錯誤信息可以看出是temp臨時表空間的數(shù)據(jù)文件有問題,解決辦法:
1、刪除臨時表空間: alter database tempfile '/opt/ora9/product/oradata/NTDB/temp1.dbf' drop;
2、重建數(shù)據(jù)文件:
alter tablespace temp add tempfile '/opt/ora9/product/oradata/NTDB/temp01.dbf' size 512M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE UNLIMITED;
通過上述兩個步驟就可以解決在進行數(shù)據(jù)庫備份時出現(xiàn)的ORACLE error 1187 encountered錯誤。

1、查看/etc/oratab這個文件:
[oracle@readhatAS53 etc]$ cat /etc/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 $ORACLE_SID are not allowed.
#
#
ORCL:/u01/oracle/product/ora10g:Y
當(dāng)$ORACLE_SID:$ORACLE_HOME:<N|Y> 設(shè)置為Y時,允許實例自啟動,當(dāng)設(shè)置為N時,則不允許自啟動。 這個文件里的配置僅僅起一個開關(guān)的作用,其并不會具體的執(zhí)行啟動和關(guān)閉,具體的操作由$ORACLE_HOME/bin/dbstart和dbshut 腳本來實現(xiàn)。 這2個腳本在執(zhí)行時會檢查/etc/oratab 文件里的配置,為Y時才能繼續(xù)執(zhí)行。因此只要將ORCL:/u01/oracle/product/ora10g:N修改為Y就行了。
2、使用root用戶在/etc/rc.d/rc.local這個文件中添加如下內(nèi)容:
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
su - oracle -c'lsnrctl start'//啟動oracle數(shù)據(jù)庫監(jiān)聽
su - oracle -c'/u01/oracle/product/ora10g/bin/dbstart start'//啟動oracle數(shù)據(jù)庫實例
su - oracle -c'/opt/tomcat/apache-tomcat-6.0.20/bin/startup.sh'//啟動tomcat服務(wù)器的配置。
3、reboot系統(tǒng),oracle數(shù)據(jù)庫與tomcat服務(wù)器就可以自動啟動了。
