Redhat 7.6 & RAC 12.2：CLSRSC-400

異常描述

1.環境描述

• 系統：Redhat 7.6
• RAC：12.2.0.1

2.問題描述
當咱們在靜默安裝GRID後，運行root.sh腳本時，會報出以下異常

3.異常輸出

參考文檔

· 參考一：http://www.xifenfei.com/2017/06/rac-12-2-root-sh-clsrsc-400.html
Redhat使用7.6之後，驗證的結果與描述有些不相符，重啓後故障會重現，不過卻告知了我異常的緣由，給了我解決方向

· 參考二： https://blog.csdn.net/johnyiyang/article/details/103006627
也許是PSU問題，也許是OPatch的緣由，總之故障以下，不過卻提供給了我打PSU的方向

· Installation Grid Infrastructure 12c Release 2 – root.sh, CLSRSC-184, CLSRSC-258 (Doc ID 2289380.1)

· The root.sh Fails with ORA-29783:GPnP Attribute SET Failed With Error [CLSGPNP_NOT_FOUND] (文檔 ID 2180883.1)

解決方案
隨着PSU、OPatch 和 Redhat的版本提高，雖然單獨一個文檔未能解決該問題，但參考各位大神的方案建議，最終仍是攻克了這個難關，以下是我整理的解決方案

1.以下是爲了解決最初遇到的bug：ACFS 致使 root.sh 執行失敗所進行的步驟
CLSRSC-400: A system reboot is required to continue installing.

• 下載最新OPatch：p6880880補丁 爲了打最新的PSU，因此下載了最新的OPatch
• 下載最新GI升級補丁：p30920127_122010_Linux-x86-64 此處是爲了修復ACFS的故障

2.執行安裝腳本
./gridSetup.sh -applyPSU /u01/app/30920127 -silent -responseFile /home/grid/grid.rsp -skipPrereqs

3.此處是爲了修復ASM啓動失敗的bug
ASM failed to start. Check /u01/app/oracle/cfgtoollogs/asmca/asmca-200419AM113741.log for details.

 2020/04/19 11:38:16 CLSRSC-184: Configuration of ASM failed
 2020/04/19 11:38:23 CLSRSC-258: Failed to configure and start ASM
 Died at /u01/app/12.2.0/grid/crs/install/crsinstall.pm line 2112.
 The command '/u01/app/12.2.0/grid/perl/bin/perl -I/u01/app/12.2.0/grid/perl/lib -I/u01/app/12.2.0/grid/crs/install /u01/app/12.2.0/grid/crs/install/rootcrs.pl ' execution failed

• 關閉selinux
• 擴展shm
• 修改配置文件
  vi /u01/app/12.2.0/grid/crs/install/crsconfig_params
  AFD_CONF=false

4.運行 root.sh腳本

5.查看狀態：成功

至此，GRID終於成功默認安裝完成，建議你們仍是使用19c吧，對比其它版本，的確要穩定許多，這次是爲了搭建DG所作的操做，因此不得已進行了一次bug的攻克。
