2011.11.23虚拟机RAC的ASM磁盘组坏块导致重建DB
刚刚在公司的一台PC机器上用vmware workstation8搭建了一套10gr2的rac环境，用的是裸设备+ASM搭建，在安装成功后，不小心被直接重启了下主机，结果再次启动虚拟机的时候提示到有磁盘损坏，也没有在意。但是在启动RAC的时候出现了问题，一开始的现象是如下几个个资源没办法随着其他资源一起启动：
ora.node1.LISTENER_NODE1.lsnr
ora.node2.LISTENER_NODE2.lsnr
ora.RAC.RAC1.inst
ora.RAC.RAC2.inst
ora.RAC.db
看具体的启动过程：
[Oracle@node1 bin]$ crs_stat -t

尝试先把lsnr起来：
[oracle@node1 bin]$ crs_start ora.node1.LISTENER_NODE1.lsnr
Attempting to start `ora.node1.LISTENER_NODE1.lsnr` on member `node1`
Start of `ora.node1.LISTENER_NODE1.lsnr` on member `node1` succeeded.
[oracle@node1 bin]$ crs_start ora.node2.LISTENER_NODE2.lsnr
Attempting to start `ora.node2.LISTENER_NODE2.lsnr` on member `node2`
Start of `ora.node2.LISTENER_NODE2.lsnr` on member `node2` succeeded.
接着启动两个inst，接着出现问题了，，inst无法拉起来：
[oracle@node1 bin]$ crs_start ora.RAC.RAC1.inst
Attempting to start `ora.RAC.RAC1.inst` on member `node1`
Start of `ora.RAC.RAC1.inst` on member `node1` failed.
node2 : CRS-1018: Resource ora.node1.vip (application) is already running on node1

您什麼時候應該使用複合索引與多個單列索引？Apr 11, 2025 am 12:06 AM

在數據庫優化中，應根據查詢需求選擇索引策略：1.當查詢涉及多個列且條件順序固定時，使用複合索引；2.當查詢涉及多個列但條件順序不固定時，使用多個單列索引。複合索引適用於優化多列查詢，單列索引則適合單列查詢。

如何識別和優化MySQL中的慢速查詢？（慢查詢日誌，performance_schema）Apr 10, 2025 am 09:36 AM

要優化MySQL慢查詢，需使用slowquerylog和performance_schema：1.啟用slowquerylog並設置閾值，記錄慢查詢；2.利用performance_schema分析查詢執行細節，找出性能瓶頸並優化。

MySQL和SQL：開發人員的基本技能Apr 10, 2025 am 09:30 AM

MySQL和SQL是開發者必備技能。 1.MySQL是開源的關係型數據庫管理系統，SQL是用於管理和操作數據庫的標準語言。 2.MySQL通過高效的數據存儲和檢索功能支持多種存儲引擎，SQL通過簡單語句完成複雜數據操作。 3.使用示例包括基本查詢和高級查詢，如按條件過濾和排序。 4.常見錯誤包括語法錯誤和性能問題，可通過檢查SQL語句和使用EXPLAIN命令優化。 5.性能優化技巧包括使用索引、避免全表掃描、優化JOIN操作和提升代碼可讀性。

描述MySQL異步主奴隸複製過程。Apr 10, 2025 am 09:30 AM

MySQL異步主從復制通過binlog實現數據同步，提升讀性能和高可用性。 1)主服務器記錄變更到binlog；2)從服務器通過I/O線程讀取binlog；3)從服務器的SQL線程應用binlog同步數據。

mysql：簡單的概念，用於輕鬆學習Apr 10, 2025 am 09:29 AM

MySQL是一個開源的關係型數據庫管理系統。 1）創建數據庫和表：使用CREATEDATABASE和CREATETABLE命令。 2）基本操作：INSERT、UPDATE、DELETE和SELECT。 3）高級操作：JOIN、子查詢和事務處理。 4）調試技巧：檢查語法、數據類型和權限。 5）優化建議：使用索引、避免SELECT*和使用事務。

MySQL：數據庫的用戶友好介紹Apr 10, 2025 am 09:27 AM

MySQL的安裝和基本操作包括：1.下載並安裝MySQL，設置根用戶密碼；2.使用SQL命令創建數據庫和表，如CREATEDATABASE和CREATETABLE；3.執行CRUD操作，使用INSERT,SELECT,UPDATE,DELETE命令；4.創建索引和存儲過程以優化性能和實現複雜邏輯。通過這些步驟，你可以從零開始構建和管理MySQL數據庫。

InnoDB緩衝池如何工作，為什麼對性能至關重要？Apr 09, 2025 am 12:12 AM

InnoDBBufferPool通過將數據和索引頁加載到內存中來提升MySQL數據庫的性能。 1)數據頁加載到BufferPool中，減少磁盤I/O。 2)臟頁被標記並定期刷新到磁盤。 3)LRU算法管理數據頁淘汰。 4)預讀機制提前加載可能需要的數據頁。

MySQL：初學者的數據管理易用性Apr 09, 2025 am 12:07 AM

MySQL適合初學者使用，因為它安裝簡單、功能強大且易於管理數據。 1.安裝和配置簡單，適用於多種操作系統。 2.支持基本操作如創建數據庫和表、插入、查詢、更新和刪除數據。 3.提供高級功能如JOIN操作和子查詢。 4.可以通過索引、查詢優化和分錶分區來提升性能。 5.支持備份、恢復和安全措施，確保數據的安全和一致性。
