本篇文章給大家分享的是有關(guān)Oracle11g RAC維護(hù)及管理的常用操作都有哪些,小編覺(jué)得挺實(shí)用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說(shuō),跟著小編一起來(lái)看看吧。
目前成都創(chuàng)新互聯(lián)公司已為近1000家的企業(yè)提供了網(wǎng)站建設(shè)、域名、虛擬主機(jī)、網(wǎng)站改版維護(hù)、企業(yè)網(wǎng)站設(shè)計(jì)、簡(jiǎn)陽(yáng)網(wǎng)站維護(hù)等服務(wù),公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略,正道將秉承"和諧、參與、激情"的文化,與客戶和合作伙伴齊心協(xié)力一起成長(zhǎng),共同發(fā)展。
1. 查看各資源狀態(tài)(nodeapps節(jié)點(diǎn)應(yīng)用程序,ASM實(shí)例,數(shù)據(jù)庫(kù)實(shí)例等):
[root@rac01 u01]# su - grid
[grid@rac01 ~]$ crs_stat -t (命令兼容10g)

在11g R2中,默認(rèn) oc4j和gsd資源是 disable 的;oc4j 是用于WLM 的一個(gè)
資源, WLM在 11.2.0.2 才可用;gsd 是 CRS 用于跟 9i RAC 進(jìn)行通信的一
個(gè)模塊,是為了向后兼容才保留的,不影響性能;建議不要?jiǎng)h除, 也不要嘗試開(kāi)
啟他們, 忽略即可。
11g RAC 常用的是下面的命令:crsctl stat resource -t .
[root@rac01 u01]# su - grid
[grid@rac01 ~]$ crsctl stat resource -t
如果后面不帶 -t , 那么可以看到相對(duì)詳細(xì)的資源信息 。
[grid@rac01 ~]$ crsctl stat resource
2. 常用開(kāi)關(guān)機(jī)命令
注意, 11g RAC 開(kāi)啟資源相對(duì)比較慢(即使命令后面顯示的資源都start succeeded,
通過(guò)crs_stat -t查看都不一定online), 請(qǐng)注意命令操作后觀察crs log變化,以免出
現(xiàn)還沒(méi)有開(kāi)啟就懷疑啟動(dòng)有異常而采取重復(fù)動(dòng)作 。
以下命令供參考:
---------------------------------------------------
在本地服務(wù)器上停止Oracle Clusterware 系統(tǒng):
[root@rac01 ~]# /u01/grid/11.2.0/bin/crsctl stop cluster
注:在運(yùn)行“crsctl stop cluster”命令之后,如果 Oracle Clusterware 管理的
資源中有任何一個(gè)還在運(yùn)行,則整個(gè)命令失敗。使用 -f 選項(xiàng)無(wú)條件地停止所有資源
并停止 Oracle Clusterware 系統(tǒng)。
[root@rac02 ~]# /u01/grid/11.2.0/bin/crsctl stop cluster -all
停止所有節(jié)點(diǎn)上的clusterware系統(tǒng)。
在本地服務(wù)器上啟動(dòng)oralce clusterware系統(tǒng):
[root@rac01 ~]# /u01/grid/11.2.0/bin/crsctl start cluster
注:可通過(guò)指定 -all 選項(xiàng)在集群中所有服務(wù)器上啟動(dòng) Oracle Clusterware 系統(tǒng)。
[root@rac02 ~]# /u01/grid/11.2.0/bin/crsctl start cluster –all
還可以通過(guò)列出服務(wù)器(各服務(wù)器之間以空格分隔)在集群中一個(gè)或多個(gè)指定的服務(wù)器上啟動(dòng) Oracle Clusterware 系
統(tǒng):
[root@rac01 ~]# /u01/grid/11.2.0/bin/crsctl start cluster -n rac01 rac02
使用 SRVCTL 啟動(dòng)/停止所有實(shí)例:
[oracle@rac01 ~]# srvctl stop database -d racdb
[oracle@rac01 ~]# srvctl start database -d racdb
參考順序
關(guān)機(jī)順序: 先關(guān)閉Oracle實(shí)例(或數(shù)據(jù)庫(kù)),然后關(guān)閉ASM實(shí)例,最后關(guān)閉節(jié)點(diǎn)應(yīng)用
程序(虛擬 IP、GSD、TNS 監(jiān)聽(tīng)器和 ONS) .
手工開(kāi)機(jī)順序: 先啟動(dòng)節(jié)點(diǎn)應(yīng)用程序(虛擬 IP、GSD、TNS 監(jiān)聽(tīng)器和 ONS)。當(dāng)成功
啟動(dòng)節(jié)點(diǎn)應(yīng)用程序后,啟動(dòng) ASM 實(shí)例。最后,啟動(dòng) Oracle 實(shí)例(相關(guān)服務(wù))以及
企業(yè)管理器數(shù)據(jù)庫(kù)控制臺(tái)。
例子:
關(guān)閉:
在節(jié)點(diǎn)1上關(guān)閉所有節(jié)點(diǎn)的clusterware(如果有資源不能被關(guān)閉,使用-f).
[root@rac01 bin]# /u01/grid/11.2.0/bin/crsctl stop cluster -all
節(jié)點(diǎn)1,2上都關(guān)閉后我們查看
[grid@rac02 rac02]$ crsctl stat resource -t
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4000: Command Status failed, or completed with errors.
開(kāi)啟:
[root@rac01 bin]# /u01/grid/11.2.0/bin/crsctl start cluster -all
一般來(lái)說(shuō),開(kāi)啟上面一個(gè)命令就夠用了,但是如果發(fā)現(xiàn)有異常,比如db等很長(zhǎng)
時(shí)間都沒(méi)有onine, 我們也可以手工開(kāi)啟數(shù)據(jù)庫(kù)(任何一個(gè)節(jié)點(diǎn)執(zhí)行):
[root@rac02 ~]# /u01/grid/11.2.0/bin/srvctl start database -d racdb
備注:
如果有需要也可以一個(gè)一個(gè)實(shí)例開(kāi)啟。
[root@rac02 ~]# /u01/grid/11.2.0/bin/srvctl start instance -d racdb -i racdb1
[root@rac02 ~]# /u01/grid/11.2.0/bin/srvctl start instance -d racdb -i racdb2
3. 常用建立表空間及加入數(shù)據(jù)文件

4. 查看ASM實(shí)例及用戶數(shù)據(jù)庫(kù)實(shí)例(注意分別是grid及oracle用戶):
查看ASM實(shí)例(以grid用戶登入,通過(guò)查看初始參數(shù)可以看到instance_name=+ASM1):
[grid@rac01 ~]$ id
uid=501(grid) gid=501(oinstall) groups=501(oinstall),504(asmadmin),506(asmdba),507(asmoper)
[grid@rac01 ~]$ sqlplus "/as sysdba"

asm_diskstring string
asm_power_limit integer 1
asm_preferred_read_failure_groups string

.....
查看用戶數(shù)據(jù)庫(kù)實(shí)例(以oracle用戶登入,查看instance_name=racdb2,顯然是用戶實(shí)例):
[root@rac02 u01]# su - oracle
[oracle@rac02 ~]$
[oracle@rac02 ~]$ sqlplus "/as sysdba"

.......
5. 查看11g 數(shù)據(jù)庫(kù)實(shí)例的alert log及trace :
[oracle@rac01 trace]$ pwd
/u01/product/oracle/diag/rdbms/racdb/racdb1/trace
[oracle@rac01 trace]$
[oracle@rac01 trace]$ vi alert_racdb1.log
6. 查看11g RAC Clusterware的log :
[root@rac01 sbin]# su - grid
[grid@rac01 ~]$
[grid@rac01 rac01]$ pwd
/u01/grid/11.2.0/log/rac01
[grid@rac01 trace]$ pwd
/u01/grid/11.2.0/log/diag/tnslsnr/rac01/listener_scan1/trace
[grid@rac01 trace]$ ls
listener_scan1.log
[grid@rac01 rac01]$ pwd
/u01/grid/11.2.0/log/rac01
[grid@rac01 rac01]$ ls
admin/ alertrac01.log crsd/ ctssd/ evmd/ gnsd/ mDNSd/ racg/
agent/ client/ cssd/ diskmon/ gipcd/ gpnpd/ ohasd/ srvm/
7. 常用集群命令
[grid@rac02 ~]$ crs_stat -t
檢查Oracle Clusterware 是否在線
[grid@rac02 ~]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
檢查cssd (Cluster Synchronization Services) 是否在線
[grid@rac02 ~]$ crsctl check cssd
CRS-272: This command remains for backward compatibility only
Cluster Synchronization Services is online
檢查crsd (Cluster Ready Services) 是否在線
[grid@rac02 ~]$ crsctl check crsd
CRS-272: This command remains for backward compatibility only
Cluster Ready Services is online
檢查evmd (Event Mananger)是否在線
[grid@rac02 ~]$ crsctl check evmd
CRS-272: This command remains for backward compatibility only
Event Manager is online
在節(jié)點(diǎn)間檢查CSS的存活
[grid@rac02 ~]$ crsctl check cluster -n rac01
**************************************************************
rac01:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online

**************************************************************
[grid@rac02 ~]$ crsctl check cluster -n rac02
**************************************************************
rac02:

**************************************************************
開(kāi)啟數(shù)據(jù)庫(kù)
[grid@rac02 ~]$ srvctl start database -d racdb
開(kāi)啟oc4j :
[grid@rac02 ~]$ ./srvctl enable oc4j
[grid@rac02 ~]$ ./srvctl start oc4j
[grid@rac02 ~]$ ./crs_stat -t
8. vote disk 管理
[grid@rac01 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2720
Available space (kbytes) : 259400
ID : 132900461
Device/File Name : +OCR_VOTE
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check bypassed due to non-privileged user
在Oracle11g R2中,不必備份voting disk, 當(dāng)任何配置發(fā)生改變,voting disk
數(shù)據(jù)會(huì)自動(dòng)備份在OCR中,并自動(dòng)恢復(fù)到任何加入的voting disk中。 從下面可以看
到OCR和VotingDisk是一個(gè)文件。
[grid@rac01 ~]$ crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 095112005ec24f57bf98f6148818cc53 (ORCL:OCR_VOTE01) [OCR_VOTE]
Located 1 voting disk(s).
[grid@rac01 ~]$
[grid@rac01 ~]$ asmcmd
ASMCMD> ls
OCR_VOTE/
ORADATA/

ASMCMD> cd ocr_vote
ASMCMD> cd rac
ASMCMD> ls
ASMPARAMETERFILE/
OCRFILE/
ASMCMD> cd ocrfile
ASMCMD> ls
REGISTRY.255.739337635
OCR 管理
[grid@rac01 ~]$ crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.1.0]
[grid@rac01 ~]$ ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 3
Total space (kbytes) : 262120
Used space (kbytes) : 2720
Available space (kbytes) : 259400
ID : 132900461
Device/File Name : +OCR_VOTE
Device/File integrity check succeeded
Device/File not configured
Device/File not configured
Device/File not configured
Device/File not configured
Cluster registry integrity check succeeded
Logical corruption check bypassed due to non-privileged user
使用下面命令(root登陸)使用 destination_file 或者 +ASM_disk_group取代現(xiàn)在的OCR Location:
# ocrconfig -replace current_OCR_location -replacement new_OCR_location
如果只有一個(gè)OCR Location, 那么使用下面的命令:
# ocrconfig -add +new_storage_disk_group
# ocrconfig -delete +current_disk_group
運(yùn)行下面的命令顯示備份:
[grid@rac01 ~]$ ocrconfig -showbackup
rac01 2011/01/08 17:54:51 /u01/grid/11.2.0/cdata/rac/backup00.ocr
rac01 2011/01/08 13:54:49 /u01/grid/11.2.0/cdata/rac/backup01.ocr
rac02 2011/01/08 06:34:46 /u01/grid/11.2.0/cdata/rac/backup02.ocr
rac01 2011/01/07 02:15:37 /u01/grid/11.2.0/cdata/rac/day.ocr
rac01 2011/01/02 07:51:43 /u01/grid/11.2.0/cdata/rac/week.ocr
PROT-25: Manual backups for the Oracle Cluster Registry are not available
當(dāng)Oracle Clusterware起來(lái)的時(shí)候,在一個(gè)節(jié)點(diǎn)上運(yùn)行ocrconfig -manualbackup命令
[grid@rac01 ~]$ ocrconfig -manualbackup
在 /u01/grid/11.2.0/cdata/rac/day.ocr下生成備份文件 backup_20100112_141900.ocr
然后使用 $ ocrconfig -showbackup 可以查看到備份信息。
運(yùn)行下面的命令檢驗(yàn)備份文件內(nèi)容及完整性。
$ ocrdump -backupfile backup_file_name
以上就是Oracle11g RAC維護(hù)及管理的常用操作都有哪些,小編相信有部分知識(shí)點(diǎn)可能是我們?nèi)粘9ぷ鲿?huì)見(jiàn)到或用到的。希望你能通過(guò)這篇文章學(xué)到更多知識(shí)。更多詳情敬請(qǐng)關(guān)注創(chuàng)新互聯(lián)行業(yè)資訊頻道。
