之前在Windows PC上时，经常使用Oracle SQL Developer进行简单的数据库操作。这是JAVA应用，显然也应该可以运行在最近新装的Ubuntu 8.04上，今天装了才发现，要用起来还是要费点功夫的。
遇到的第一个问题是我启动SQL Developer后，主界面只出现一个窗体框，不能显现其中的内容，倒是可以看"每日提示"。Google了一下，找到一篇相关文章(原本来不了可以看Google的cache)，，是由于我启动了Ubuntu的Visual Effects到"Extra"级别后于Java Swing的一些不兼容所致，是一个已知问题。解决办法最简单的就是关掉Ubuntu的Visual Effects，当然我可不想这样干，还有一种办法就是在sqldeveloper.sh脚本第二行加上下面一句:
export AWT_TOOLKIT="MToolkit"
终于可以看到SQL Developer的界面啦!
但很快我又发现了另外的问题，数据库中的中文字符都变成了方块，这个问题是由于Java缺失字体造成的，大家可以参看Chinese Debian Mini Howto5.7节的说明。解决方法也copy一下，就是创建一个/{你的jdk路径}/jre/lib/fonts/fallback目录，然后copy或链接上系统中可以正常使用的中文字体到这个目录就可以了。
Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool 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.
