DBCA建库找不到ASM磁盘一例
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
node1:
su - grid

通過(guò)asmcmd命令查看，能正?？吹絘sm磁盤組里面的文件
- 通過(guò)截圖報(bào)錯(cuò)查看dbca日志和所示的oraagent_oracle.log?
dbca日志?

日志提示無(wú)法訪問(wèn)spfile文件，但是能通過(guò)grid用戶在磁盤組里發(fā)現(xiàn)這些文件，詭異。?
那么思考原因：?
dbca建立數(shù)據(jù)庫(kù)是oracle用戶操作，而grid用戶是管理磁盤組的，明顯現(xiàn)象是，在節(jié)點(diǎn)2上oracle用戶無(wú)法讀取或訪問(wèn)asm磁盤組的文件，所以才可能出現(xiàn)此問(wèn)題
node1 :
id oracle
uid=501(oracle) gid=5001(oinstall) 組=5001(oinstall),5002(dba),5003(oper),5006(asmdba)
node2:
uid=501(oracle) gid=5001(oinstall) 組=5001(oinstall),5002(dba),5003(oper),5006(asmdba)
查看GRID_HOME和ORACLE_HOME的bin目錄下oracle文件的權(quán)限：
node1:
cd
$GRID_HOME/bin
ls
-l oracle
-rwsr-s--x
1 grid oinstall
209914519 9月
7 14:
40 oracle 文件權(quán)限正確
node2:
ls
-lrt oralce
-rwxr-x--x
1 grid oinstall
209914519 9月
7 14:
42 oracle 文件權(quán)限錯(cuò)誤
oracle用戶：
cd
$ORACLE_HOME/bin
ls
-l oracle
node1:
-rwsr-s--x
1 oracle asmadmin
239626689 9月
7 15:
56 oracle 正確
node2:
-rwsr-s--x
1 oracle asmadmin
239626689 9月
7 16:
04 oracle 正確
問(wèn)題明確：?
在node2的，GRID_HOME/bin目錄下，oracle文件權(quán)限錯(cuò)誤?
修改：?
chmod +s oracle?
重新回到DBCA建庫(kù)界面繼續(xù)執(zhí)行，則會(huì)成功發(fā)現(xiàn)ASM磁盤組，并成功建庫(kù)。
與50位技術(shù)專家面對(duì)面20年技術(shù)見證，附贈(zèng)技術(shù)全景圖
總結(jié)
以上是生活随笔為你收集整理的DBCA建库找不到ASM磁盘一例的全部?jī)?nèi)容，希望文章能夠幫你解決所遇到的問(wèn)題。
如果覺(jué)得生活随笔網(wǎng)站內(nèi)容還不錯(cuò)，歡迎將生活随笔推薦給好友。
