本篇內容介紹了“RAC怎么擴大online日志組大小”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
1.查看當前默認日志組
|
SQL> select GROUP#,THREAD#,SEQUENCE#,BYTES,MEMBERS,ARCHIVED,STATUS from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS ---------- ---------- ---------- ---------- ---------- --- ---------------- 1 1 821 52428800 1 YES INACTIVE 2 1 822 52428800 1 NO CURRENT 3 2 241 52428800 1 YES INACTIVE 4 2 242 52428800 1 NO CURRENT |
2.添加日志組和成員
|
節點1 alter database add logfile thread 1 group 11 ('+DATA/funddb/onlinelog/redo11a.log','+DATA/funddb/onlinelog/redo11b.log') size 500M; alter database add logfile thread 1 group 12 ('+DATA/funddb/onlinelog/redo12a.log','+DATA/funddb/onlinelog/redo12b.log') size 500M; alter database add logfile thread 1 group 13 ('+DATA/funddb/onlinelog/redo13a.log','+DATA/funddb/onlinelog/redo13b.log') size 500M; 節點2 alter database add logfile thread 2 group 14 ('+DATA/funddb/onlinelog/redo14a.log','+DATA/funddb/onlinelog/redo14b.log') size 500M; alter database add logfile thread 2 group 15 ('+DATA/funddb/onlinelog/redo15a.log','+DATA/funddb/onlinelog/redo15b.log') size 500M; alter database add logfile thread 2 group 16 ('+DATA/funddb/onlinelog/redo16a.log','+DATA/funddb/onlinelog/redo16b.log') size 500M; |
3.切換日志
|
節點1 SQL> alter system switch logfile; System altered. 節點2 SQL> alter system switch logfile; System altered. |
4.查詢并等待
|
SQL> select GROUP#,THREAD#,SEQUENCE#,BYTES,MEMBERS,ARCHIVED,STATUS from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS ---------- ---------- ---------- ---------- ---------- --- ---------------- 1 1 821 52428800 1 YES INACTIVE 2 1 822 52428800 1 YES ACTIVE 3 2 241 52428800 1 YES INACTIVE 4 2 242 52428800 1 YES ACTIVE 11 1 823 524288000 2 NO CURRENT 12 1 0 524288000 2 YES UNUSED 13 1 0 524288000 2 YES UNUSED 14 2 243 524288000 2 NO CURRENT 15 2 0 524288000 2 YES UNUSED 16 2 0 524288000 2 YES UNUSED 10 rows selected. 等待...... SQL> select GROUP#,THREAD#,SEQUENCE#,BYTES,MEMBERS,ARCHIVED,STATUS from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS ---------- ---------- ---------- ---------- ---------- --- ---------------- 1 1 821 52428800 1 YES INACTIVE 2 1 822 52428800 1 YES INACTIVE 3 2 241 52428800 1 YES INACTIVE 4 2 242 52428800 1 YES INACTIVE 11 1 823 524288000 2 NO CURRENT 12 1 0 524288000 2 YES UNUSED 13 1 0 524288000 2 YES UNUSED 14 2 243 524288000 2 NO CURRENT 15 2 0 524288000 2 YES UNUSED 16 2 0 524288000 2 YES UNUSED 10 rows selected. |
5.刪除舊日志組
|
SQL> alter database drop logfile group 1; Database altered. SQL> alter database drop logfile group 2; Database altered. SQL> alter database drop logfile group 3; Database altered. SQL> alter database drop logfile group 4; Database altered. |
6.確認完成日志組的擴大
|
SQL> select GROUP#,THREAD#,SEQUENCE#,BYTES,MEMBERS,ARCHIVED,STATUS from v$log; GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS ---------- ---------- ---------- ---------- ---------- --- ---------------- 11 1 823 524288000 2 NO CURRENT 12 1 0 524288000 2 YES UNUSED 13 1 0 524288000 2 YES UNUSED 14 2 243 524288000 2 NO CURRENT 15 2 0 524288000 2 YES UNUSED 16 2 0 524288000 2 YES UNUSED |
