网站权重有时降,织梦 网站统计,南京建设教育网站,搜狗seo快速排名公司真是大大的回旋镖，小伙伴们还记得上一期为了测试23ai flashback log palcement，于是给11g和19c都给检查了db_recovery_file_dest的设置和大小，当时示例归档是默认已开启的状态。 直接给一个instance 19c的19.3单实例的主机给设置了db_recove…

真是大大的回旋镖，小伙伴们还记得上一期为了测试23ai flashback log palcement，于是给11g和19c都给检查了db_recovery_file_dest的设置和大小，当时示例归档是默认已开启的状态。

直接给一个instance 19c的19.3单实例的主机给设置了db_recovery_file_dest大小.

于是发生了重启示例失败，重新检查参数和修改归档内容，重复自己写的步骤，大大的回旋。

一、重启示例（测试业务反馈卡）

shutdown immediate
--发现等待了很久很久都没有关闭，
--现场以为是Oracle Linux 8.10至少一年没重启了，有事务卡住了
--直接在终端reboot

二、实例开启失败 

[root@test19 ~]# su - oracle

三、尝试startup mount ，alter database open 

[oracle@test19:/home/oracle]# sqlplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Fri Jun 13 19:05:56 2025

SYS@test19> exit

四、检查parameter和archive归档 

[oracle@test19:/home/oracle]# sqlplus / as sysdba;SQL*Plus: Release 19.0.0.0.0 - Production on Sat Jun 14 09:12:00 2025
Version 19.3.0.0.0Copyright (c) 1982, 2019, Oracle.  All rights reserved.Connected to an idle instance.SYS@test19> startup mount;
ORACLE instance started.Total System Global Area 8.5899E+10 bytes
Fixed Size                 30381736 bytes
Variable Size            1.0737E+10 bytes
Database Buffers         7.4893E+10 bytes
Redo Buffers              238051328 bytes
????????
SYS@test19> show parameter db_recovery;NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest                string      /u01/app/oracle/recovery_area
db_recovery_file_dest_size           big integer 50G

五、修改parameter 后

 删除7天前

delete archivelog all completed before 'sysdate-7';

Do you really want to delete the above objects (enter YES or NO)? YES
deleted archived log
archived log file name=/u01/app/oracle/recovery_area/TEST19/archivelog/2024_09_11/o1_mf_1_793_mg38m90v_.arc RECID=1 STAMP=1179439209

Deleted 489 objectsRMAN> exitRecovery Manager complete.

六、再次检查归档文件db_recovery_file_dest空间占用

[root@test19 recovery_area]# du -sh *
51G     TEST19
[root@test19 recovery_area]#
--删除后
[root@test19 recovery_area]# du -sh *
224M    TEST19
[root@test19 recovery_area]#

 检查parameter参数

SYS@test19> startup mount
ORACLE ???????
Total System Global Area 8.5899E+10 bytes
Fixed Size                 30381736 bytes

Database Buffers         7.4893E+10 bytes
Redo Buffers              238051328 bytes
????????
SYS@test19> alter database open;
???????
SYS@test19> select INSTANCE_NAME,HOST_NAME,STARTUP_TIME,STATUS,ACTIVE_STATE from v$instance;
INSTANCE_NAME    HOST_NAME                             STARTUP_TI STATUS       ACTIVE_ST
test19           test19                                                           14-6? -25  OPEN         NORMAL
SYS@test19> SHOW PARAMETER DB_RECOVERY;
NAME                                 TYPE                   VALUE
db_recovery_file_dest                string      /u01/app/oracle/recovery_area
db_recovery_file_dest_size           big integer 100G

七、解决终端？乱码 


[oracle@test19:/home/oracle]# vi .bash_profile# User specific environment and startup programsPATH=$PATH:$HOME/.local/bin:$HOME/binexport PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_SID=test19
export ORACLE_UNQNAME=test19
export ORACLE_HOSTNAME=test19
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.3.0/dbhome_1
export TNS_ADMIN=$ORACLE_HOME/network/admin
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH:$ORACLE_HOME/OPatch
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export LANG=zh_CN.UTF-8
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.AL32UTF8"
umask 022
alias sas='sqlplus / as sysdba'
export PS1="[`whoami`@`hostname`:\$PWD]# "
alias sqlplus='rlwrap sqlplus'
alias rman='rlwrap rman'
alias lsnrctl='rlwrap lsnrctl'
alias asmcmd='rlwrap asmcmd'
alias adrci='rlwrap adrci'

重新检测 中文显示

[oracle@test19:/home/oracle]# source .bash_profile
