将数据库的归档目录改回到ASM上，马上就可以看到新的归档日志的名称：
| SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_1 = 'LOCATION=+DISK/testrac/' SCOPE = MEMORY SID = 'testrac1'; |
系统已更改。
| SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_1 = 'LOCATION=+DISK/testrac/' SCOPE = MEMORY SID = 'testrac2'; |
系统已更改。
| SQL> ALTER SYSTEM ARCHIVE LOG CURRENT; |
系统已更改。
| SQL> SELECT NAME, COUNT(*) FROM V$ARCHIVED_LOG GROUP BY NAME; NAME COUNT(*) ------------------------------------------------------------ ---------- 250 +DISK/testrac/2_208_618591128.dbf 1 +DISK/testrac/1_292_618591128.dbf 1 |
关闭数据库，使刚才的归档参数的修改失效，归档路径恢复到本地，再次查询：
| SQL> SELECT NAME, COUNT(*) FROM V$ARCHIVED_LOG GROUP BY NAME; NAME COUNT(*) ------------------------------------------------------------ ---------- 250 /data1/archivelog/2_209_618591128.dbf 1 /data1/archivelog/1_293_618591128.dbf 1 +DISK/testrac/2_208_618591128.dbf 1 +DISK/testrac/1_292_618591128.dbf 1 |
目前仍然可以看到所有的归档日志名称，下面尝试用rman删除所有的归档日志。
| SQL> SELECT NAME, COUNT(*) FROM V$ARCHIVED_LOG GROUP BY NAME; NAME COUNT(*) ------------------------------------------------------------ ---------- 256 |
