環境描述：
操作系統版本：Red Hat Enterprise Linux Server release 6.5 (Santiago)
數據庫版本：Oracle 11.2.0.4 RAC
場景描述：
Oracle RAC環境搭建完成之后，數據庫可以啟動到mounted狀態，無法啟動到open狀態；其他的CRS集群服務、ASM服務狀態正常！！！
處理過程：
[oracle@oracle01 ~]$ sqlplus / as sysdba; SQL*Plus: Release 11.2.0.4.0 Production on Thu Jun 15 12:48:00 2017 Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP, Data Mining and Real Application Testing options SQL> SQL> select open_mode from v$database; OPEN_MODE -------------------- MOUNTED SQL> alter database open; alter database open * ERROR at line 1: ORA-01154: database busy. Open, close, mount, and dismount not allowed now
++++++++++++++++++++++++++++++++++++++++++
再次嘗試：
SQL> alter database open; alter database open * ERROR at line 1: ORA-01154: database busy. Open, close, mount, and dismount not allowed now 啟動數據庫一直停留在Database mounted. 最后報ORA-03113: end-of-file on communication channel
++++++++++++++++++++++++++++++++++++++++
查看告警日志，輸出如下錯誤信息：

有戲！！！
初步分析是：日志不能正常歸檔，導致了數據庫只能在mounted狀態，在往open狀態切換的時候，找不到相關的日志歸檔路徑，導致數據庫不能啟動到open狀態
++++++++++++++++++++++++++++++++++++++++
開始處理：
首先查看數據庫當前啟動狀態：
SQL> select open_mode from v$database; OPEN_MODE -------------------- MOUNTED
查看當前數據庫的歸檔路徑設置：
注：數據庫在open狀態下，可以通過如下命令查看歸檔信息，
SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination +FRA/archivelog/ Oldest online log sequence 8 Next log sequence to archive 9 Current log sequence 9
數據庫在mounted狀態下的時候，需要通過查看參數文件來確認：
SQL> set linesize 200 SQL> set pagesize 100 SQL> show parameter log_ NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ audit_syslog_level string commit_logging string db_create_online_log_dest_1 string db_create_online_log_dest_2 string db_create_online_log_dest_3 string db_create_online_log_dest_4 string db_create_online_log_dest_5 string enable_ddl_logging boolean FALSE log_archive_config string log_archive_dest string .. .. .. .. .. .. .. ....... log_archive_dest_1 string LOCATION=+FRA/archivelog/ log_archive_dest_state_4 string enable log_archive_dest_state_5 string enable log_archive_dest_state_9 string enable log_archive_duplex_dest string log_archive_format string %t_%s_%r.dbf log_archive_local_first boolean TRUE log_archive_max_processes integer 4 log_archive_min_succeed_dest integer 1 log_archive_start boolean FALSE log_archive_trace integer 0 log_buffer integer 2379776 log_checkpoint_interval integer 0 log_checkpoint_timeout integer 1800 log_checkpoints_to_alert boolean FALSE log_file_name_convert string remote_login_passwordfile string EXCLUSIVE sec_case_sensitive_logon boolean TRUE sec_max_failed_login_attempts integer 10
可以看出歸檔日志的路徑是：LOCATION=+FRA/archivelog/
+++++++++++++++++++++++++++++++++++
切換到oracle用戶或者grid用戶下，執行asmcmd查看磁盤組信息：
[grid@oracle01 ~]$ asmcmd ASMCMD> ls BAK/ CRS/ DATA/ FRA/ ASMCMD> ASMCMD> cd FRA ASMCMD> ls EBJDB/ ASMCMD> 發現沒有+FRA/archivelog目錄，我們在+FRA目錄下，創建archivelog目錄： ASMCMD> pwd +FRA ASMCMD> mkdir archivelog archivelog/ ASMCMD> cd archivelog ASMCMD> pwd +FRA/archivelog ASMCMD>
OK！！！！！！歸檔日志目錄設置完畢！
++++++++++++++++++++++++++++++++++++++
回到sqlplus界面，
SQL> alter database open; SQL> select instance_name,status from v$instance; INSTANCE_NAME STATUS ---------------- ------------ EBJDB1 OPEN
查看集群服務狀態：
[grid@oracle01 ~]$ crsctl stat res -t -------------------------------------------------------------------------------- NAME TARGET STATE SERVER STATE_DETAILS -------------------------------------------------------------------------------- Local Resources -------------------------------------------------------------------------------- ora.BAK.dg ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.CRS.dg ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.DATA.dg ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.FRA.dg ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.LISTENER.lsnr ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.asm ONLINE ONLINE oracle01 Started ONLINE ONLINE oracle02 Started ora.gsd ONLINE OFFLINE oracle01 ONLINE OFFLINE oracle02 ora.net1.network ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.ons ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 ora.registry.acfs ONLINE ONLINE oracle01 ONLINE ONLINE oracle02 -------------------------------------------------------------------------------- Cluster Resources -------------------------------------------------------------------------------- ora.LISTENER_SCAN1.lsnr 1 ONLINE ONLINE oracle01 ora.cvu 1 ONLINE ONLINE oracle01 ora.db.db 1 ONLINE ONLINE oracle01 Open 2 ONLINE ONLINE oracle02 Open ora.oracle01.vip 1 ONLINE ONLINE oracle01 ora.oracle02.vip 1 ONLINE ONLINE oracle02 ora.oc4j 1 ONLINE ONLINE oracle01 ora.scan1.vip 1 ONLINE ONLINE oracle01
OK!!! 焦急的心情稍許平靜！！！！有木有！！！
網上查找各種資料的時候，心情特別難受，都開始懷疑人生了，對面的純開發同事，人家一天啥事沒有。。。。。這次問題雖然解決了，以后估計還會有相同的想法， 哈哈！！！
