Grid Control一些術(shù)語GC、OMS、OMR、OMA的概念

發(fā)布時(shí)間：2020-08-08 20:07:24 來源：ITPUB博客閱讀：310 作者：lusklusklusk 欄目：關(guān)系型數(shù)據(jù)庫

EM:database control
GC:grid control
CC:cloud control(12開始就不叫GC了改叫CC了，目前有12CC、13CC)

OMR
Oracle Management Repository
OMR就是存放GC監(jiān)控信息的數(shù)據(jù)庫，一般存放在sysman用戶下的表，因?yàn)橐玫奖O(jiān)控報(bào)警，所以要用到dbsnmp用戶，所以要開啟sysman、dbsnmp兩個(gè)用戶
/etc/hsots必須有OMR和OMS的信息

OMS
Oracle Management Service
OMS簡單可以簡單理解為GC監(jiān)控，安裝了weblogic和grid control軟件，其中在安裝grid contro過程中要指定OMR服務(wù)器的信息。
OMS安裝好后，自動(dòng)在本機(jī)安裝了OMA服務(wù)
/etc/hsots必須有OMR和OMS的信息
/etc/oratab信息默認(rèn)如下（分別是OMS、OMA的HOME目錄，可以修改*為oms和agent）
*:/u01/app/bea/oracle/Middleware/oms11g:N
*:/u01/app/bea/oracle/Middleware/agent11g:N

OMA
Oracle Management Agent
被監(jiān)控的服務(wù)器，/etc/hosts必須要有OMS的域名信息
一般一臺(tái)服務(wù)器裝一套OMA就可以了，但是如果有不同的OMS的來監(jiān)控服務(wù)器，比如13c，12c同時(shí)監(jiān)控同一臺(tái)服務(wù)器，則這臺(tái)服務(wù)器需要兩套OMA，且版本應(yīng)該不一樣。
安裝OMA的方法
1、登錄OMS服務(wù)器
. oraenv -> oms
cd $ORACLE_HOME/sysman/agent_download/11.1.0.1.0//
copy agentDownload.linux到OMA服務(wù)器比如/home/oracle
2、登錄OMA服務(wù)器
./agentDownload.linux -b /u01/app/oracle/product/11.2.0 -y --安裝好后，默認(rèn)連接OMS的4900端口
-y表示Decline Security Updates，表示不需要輸入郵箱地址
3、安裝好后，/etc/oratab默認(rèn)有如下信息
agent:/u01/app/oracle/product/11.2.0/agent11g:N（即第二步-b時(shí)指定的HOME目錄加agent11g子目錄，可以修改*為agent）
OMA安裝過程中一定要注意：輸入正確的registration password，否則雖然可以正常安裝agent，但是永遠(yuǎn)連不上OMS
Grid Control一些術(shù)語GC、OMS、OMR、OMA的概念

OMS的啟動(dòng)關(guān)閉
emctl start oms
emctl stop oms
emctl status oms
emctl status oms -details
emctl status oms -details -sysman_pwd sysman'spassword

OMA的啟動(dòng)關(guān)閉
emctl start agent
emctl stop agent
emctl status agent

OMA連不上OMS的現(xiàn)象和處理方法
1、如果安裝agent過程中輸錯(cuò)了密碼，連不上OMS，則如下
emctl upload agent
emctl verifykey
emctl secure agent
比如
EMD pingOMS error: Failure connecting to https://gc.oracle.com:4900/em/upload/ , err -1

2、如果重新在其他目錄安裝了agent，連不上OMS，則如下查看什么報(bào)錯(cuò)
emctl upload agent
emctl verifykey
比如
EMD pingOMS error: Invalid ping response "ERROR-Agent is blocked... Please contact EM adminstrator to unblock the agent"
則進(jìn)入em界面，setup->agent->unblock

3、最后都不行的話重啟OMS，再如上1、2兩種方式

OMA\OMS日志目錄
OMS日志在gc_inst運(yùn)行時(shí)的目錄里，即$INST_HOME/em/EMGC_OMS1/sysman/log
OMS:/u01/app/bea/oracle/gc_inst/em/EMGC_OMS1/sysman/log

agent日志$AGENT_HOME/sysman/log
OMA:/u01/app/bea/oracle/Middleware/agent11g/sysman/log
