oracle修改归档日志路径
一：先查询数据库是否开启归档模式：
SQL> archive log list; ----已经开启归档模式
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST----修改此归档路径
Oldest online log sequence 3
Next log sequence to archive 5
Current log sequence 5
二：创建归档目录：
[root@athena ~]# mkdir -p /oracle/archive1
[root@athena ~]# mkdri -p /oracle/archive2
三：设置数据库归档日志目标：
SQL> alter system set log_archive_dest_1='location=/oracle/archive1/'scope=spfile;
System altered.
SQL> alter system set log_archive_dest_1='location=/oracle/archive2/'scope=spfile;
System altered.
SQL> alter system set log_archive_format='arch_%d_%t_%r_%s.log'scope=spfile;
System altered.
四：重启数据库：
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.
Total System Global Area 835104768 bytes
Fixed Size 2232960 bytes
Variable Size 633343360 bytes
Database Buffers 197132288 bytes
Redo Buffers 2396160 bytes
Database mounted.
SQL> alter database archivelog;---------如果之前没有开启归档的，应该在Mount状态下开启归档模式
Database altered.
SQL> alter database open;
Database altered.
五：确认数据库为归档日志模式，并用下列两个查询运行归档器：
SQL> select log_mode from v$database;
LOG_MODE
------------
ARCHIVELOG
SQL> select archiver from v$instance;
ARCHIVE
-------
STARTED
六：强制日志切换：
SQL> alter system switch logfile;
System altered.
SQL> select name from v$archived_log;
NAME
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

7 rows selected.
----------发现没有发生归档日志
问题排查:
一：进数据库后台查询日志报告：
ORA-16014: log 2 sequence# 5 not archived, no available destinations
ORA-00312: online log 2 thread 1: '/s01/oracle/oradata/athena/redo02.log'
Mon Jun 23 22:49:18 2014
ARC2: Error 19504 Creating archive log file to '/oracle/archive2/arch_4e31002f_1_841143545_5.log'
ARCH: Archival stopped, error occurred. Will continue retrying
ORACLE Instance athena - Archival Error
ORA-16038: log 2 sequence# 5 cannot be archived
ORA-19504: failed to create file ""
ORA-00312: online log 2 thread 1: '/s01/oracle/oradata/athena/redo02.log'
Mon Jun 23 22:49:18 2014
经过查询是权限不对，因为在root下创建的目录，oracle并没有权限：
[root@athena oracle]# chown oracle:oinstall archive1
[root@athena oracle]# chown oracle:oinstall archive2
继续查询：
SQL> select name from v$archived_log;
NAME
