HomeDatabaseMysql Tutorial 粗心导致ORA-16020错误(fewer destinations available than specified

一次在切换归档日志时sqlaltersystemswitchlogfile;时停了好久都没反应;查看确实在归档模式下:SQLarchiveloglist;DatabaselogmodeArchiveModeAutomaticarch..

一次在切换归档日志时


sql>alter system switch logfile; 时停了好久都没反应;


查看确实在归档模式下:

SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /db/oracle/archiveback
Oldest online log sequence     3
Next log sequence to archive   3
Current log sequence           5



查看有几组日志:

SQL> select group#,THREAD#,MEMBERS,STATUS from v$log;

   GROUP#    THREAD#    MEMBERS STATUS
---------- ---------- ---------- ----------------
        1          1          1 INACTIVE
        3          1          1 INACTIVE
        2          1          1 CURRENT


网上资料说“如果数据库处于归档模式下,当执行alter system switch logfile操作后,Oracle接
下来需要进行日志切换。在进行日志切换之前,Oracle首先检查将要切换到的下一个日志文件是否已归档,而你的数据库是处于归档模式但不是自动归档,所以Oracle需要等待进行手工归档,再进行切换。而在你还没进行手工归档需要归档的日志之前,服务器空间,数据库实际上已经挂起并等待手工归档,所以出现了以上的问题。”先进性手动归档:

解决办法:
1、将末归档的日志手工归档:
  SQL>shutdown immediate
  SQL>startup mount
  SQL>alter system archive log all;
  打开数据库:
  SQL>alter database open;
2、将数据库置于自动归档状态:
  SQL>alter system set log_archive_start=true scope=spfile;
  SQL>shutdown immediate
  SQL>startup


安装步骤我的还是报错


SQL> alter system archive log all;
alter system archive log all
*
ERROR at line 1:
ORA-16020: fewer destinations available than specified by
LOG_ARCHIVE_MIN_SUCCEED_DEST


网上这篇文章介绍了怎么解决ora-16020的错误”“

而我的还是行不通;


于是进一步检查归档文件的属性发现问题所在:

SQL> show parameter archive

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
archive_lag_target                   integer     0
log_archive_config                   string
log_archive_dest                     string
log_archive_dest_1                   string    location=/db/oracle/archiveback


[oracle@oracle11g oracle]$ ll
total 40
drwxr-x--- 5 oracle oinstall 4096 Jun 18 16:47 admin
drwxr-xr-x 2 root   root     4096 Jun 19 10:20 archiveback
drwxr-xr-x 2 oracle oinstall 4096 Jun 18 20:16 backup


[root@oracle11g oracle]# chown -R oracle:oinstall archiveback/


SQL> alter system archive log all;   //在此执行手动归档成功;

System altered.


SQL> select open_mode,log_mode from v$database;

OPEN_MODE            LOG_MODE
-------------------- ------------
MOUNTED              ARCHIVELOG

SQL> alter database open;

Database altered.


SQL> alter system switch logfile;

System altered.

问题解决,原来是自己修改了归档的存放地点,网站空间,香港虚拟主机,而忘记了修改权限导致!

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
