安装硬件(已经正常安装)：
Server: Dell PowerEdge 2600 双至强 2.8G 1G内存
PC: P4 2.4GB 512M内存
说明：
前几天在Win2000下装两年前下的Oracle 8.1.7 NTEE Release 1(企业版),发现运行了Setup文件以后任务管理器显示CPU使用占满了,过几秒钟又下来了,但什么东西也没运行,进程里也没显示出来。
(以前曾经安装过，没有任何问题)之后把installwin32下的setup.exe文件移走再运行，提示说jrew.exe找不到，就以为是jre出问题了，安装了一个1.1.8版的，查出来有两处jrew里的bin目录下的文件全部都用1.1.8的覆盖了，(1.3.1的文件已经完全不一样了).
这时候可以安装了，能够启动Universal Install,可以一直复制文件，但到建数据库时没动静了。
NET8的两项工具也都启不来了。实际上Oracle的安装还是失败的(唉，安了好几次啊，每次都是用XP格了重装)把个人版和企业版都装过了，然后又下了Release 3的企业版，还是一样，昨天上这儿来看了一下，有人说是symcjit.dll出错，还说要改一堆东西就想试一下，不过才懒得改那么多东西呢，就把2000先GHOST了一下(3年多没用这玩意了，5.1做2000好象不太好,恢复时老是丢失kernal32文件，要恢复两次才行)，省得老装，然后把找到的两处symcjit.dll改名为symcjit_.dll(本人习惯，不爱改成.old),然后拖进WINISO里做成ISO包(想没问题的话就直接刻了，做成ISO虚拟光驱，文件就不会受影响，以免安装程序修改了安装源文件)然后可以安装了，一步步下去都没问题，没选自定义，全部都是默认的(企业版嘛，当然按企业的规格装了,呵呵)。
建立数据库也正常，NET8和另外几个也全部都起来了，装完之后内存就占到390兆(如果NET8没起来的话,还是130M左右，已经装了SQL Server，要占得多一点)
总之没有任何错误提示。所以认为是好的，同时也在两台机器上安装过了(一台DELL 2600服务器，一台PC)，都没有问题。
之所以安装8.1.7主要还是因为Ora9实在太大，，在对三张光盘解压缩后的文件(Release 1)查病毒后居然有18万个文件，安装之后居然占3个G(本人用的FAT32)，真是个大垃圾，还标称是1.7G。而8.1.7标称为790M,但装上为1G，(这都是刚装完的大小，往后不得更大了!)而且做为学习和开发来说，有一个比较好用的版本就可以了，才不想装那么大的呢。
看到很多人都在安装时有问题，所以把我的方法给大家做个参考，不敢保证每位朋友都能这样安装上。
同时因为Ora8企业版可以安装，因此就没有在9上进行测试了，但直接安装的话Net Assistant也是配置不成功的。
另外，可能有的朋友想找Oracle的安装程序，都是光盘容量的，所以很难找，我也是两年前在OTN上注册后才发现Oracle网站上居然可以下到。
如果要下的朋友可以在OTN.Oracle.com上注册一下，登录后选上面的Download按钮就可以下到几乎所有的Oracle产品了.
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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
