Counld not connect to ASM due to following error,ora-12547:TNS:lost comact

Red Hat Linux5.5 安裝RAC11.2.03，dbca時報錯：

 

解決辦法：

[grid@liuqi1 oracle]$ cd $ORACLE_HOME/bin

[grid@liuqi1 bin]$ ll oracle

-rwxr-x--x 1 grid oinstall 203974257 Mar  9 20:42 oracle

[grid@liuqi1 bin]$ chmod 6751 oracle

[grid@liuqi1 bin]$ ll oracle

-rwsr-s--x 1 grid oinstall 203974257 Mar  9 20:42 oracle

[grid@liuqi1 bin]$

將$GRID_HOME/bin和$ORACLE_HOME/bin下的oracle都賦6751許可權：

chmod 6751 $GRID_HOME/bin/oracle

chmod 6751 $ORACLE_HOME/bin/oracle
