ORACLE_BASE安装好后是有root权限的。

而ORACLE_HOME则没有. 这样才对:ORACLE_BASE=/home/grid/app ORACLE_HOME=/home/grid/11.2.0/grid 3.在安装grid到最后一步堕落误， 1.在rac2节点利用oracleasm找不到共享磁盘 [root@rac2 ~]# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... [root@rac2 ~]# 办理要领: 是因为在rac1节点名目化磁盘没有利用partprobe呼吁，查察了下asm只能挂载本身在磁盘组，我是用iscsi做的共享， all named directories in the software location path will acquire root ownership. This may create problems for subsequent installations into the same Oracle base. ACTION: Specify software location outside of Oracle base 办理要领: 我当前目次是:ORACLE_BASE=/home/grid ORACLE_HOME=/home/grid/11.2.0/grid 这样目次是不正确的，将共享磁盘换成虚拟机自带的磁盘共享就办理了. ，是因为scan的IP问题补占用了 日志: INFO: All nodes have same "hosts" entry defined in file "/etc/nsswitch.conf" INFO: Check for integrity of name service switch configuration file "/etc/nsswitch.conf" passed INFO: ERROR: INFO: PRVG-1101 : SCAN name "scan-cluster" failed to resolve INFO: ERROR: INFO: PRVF-4657 : Name resolution setup check for "scan-cluster" (IP address: 192.168.3.155) failed INFO: ERROR: INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "scan-cluster" INFO: Verification of SCAN VIP and Listener setup failed INFO: Checking OLR integrity... INFO: Checking OLR config file... INFO: OLR config file check successful INFO: Checking OLR file attributes... INFO: OLR file check successful 办理要领: (1).直接跳过不影响 (2)，分区没有生效 在rac1执行: [root@rac1 ~]# partprobe 在rac2执行: [root@rac2 ~]# /usr/sbin/oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks... Instantiating disk "VOL04" Instantiating disk "VOL03" Instantiating disk "VOL01" Instantiating disk "VOL02" [root@rac2 ~]# /usr/sbin/oracleasm listdisks VOL01 VOL02 VOL03 VOL04 [root@rac2 ~]# 2.安装grid集群软件时呈现ORACLE_HOME和ORACLE_BASE目次差池 错误提示: INS-32026]The Software Location specified should not be under Oracle base location. CAUSE: Grid Infrastructure for a Cluster installation will assign root ownership to all parent directories of clusterware software location. As a result，修改系统的nslookup二进制文件() 4.crs无法共享磁盘通信 错误信息: CRS-0184: Cannot communicate with the CRS daemon. 日志信息: 2016-09-16 09:20:45.508: [ CRSPE][1175734592]{1:19372:2} Reading (12) resources 2016-09-16 09:20:45.510: [ CRSPE][1175734592]{1:19372:2} Reading (15) types 2016-09-16 09:20:46.087: [ CRSPE][1175734592]{1:19372:2} Reading (2) server pools 2016-09-16 09:20:48.321: [ OCRRAW][1171532096]proprseterror: Error in accessing physical storage [26] Marking context invalid. 2016-09-16 09:20:48.321: [ OCRRAW][1171532096]proprdc: backend_ctx-prop_ctx_tag=PROPCTXT 2016-09-16 09:20:48.325: [ OCRRAW][1171532096]proprdc: backend_ctx-prop_valid=0 2016-09-16 09:20:48.325: [ OCRRAW][1171532096]proprdc: backend_ctx-prop_boot_mode=1 办理要领: 这是共享磁盘的问题，因为ORACLE_BASE和ORACLE_HOME目次要分隔，。
