今天，视图将两张大表用 expdp方式备份到一个挂载的nfs 磁盘上去的时候，遇到 ORA-27054: NFS file system where the file is created or resides is not mounted with correct options 的错误。
网上查了一下，主要有三种解决办法：
1、打补丁：5146667
2、在mount的时候设置参数：rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0
如 mount -v nfs -o rw,bg,hard,rsize=32768,wsize=32768,vers=3,nointr,timeo=600, proto=tcp 192.168.10.49:/storage/rmanbak /home/Oracle/rmanbak
3、在数据库里面执行 SQL>Alter system set events '10298 trace name context forever,level 32' （SCOPE=SPFILE） ;
注：括号里面是是表示要不要将修改写入 spfile 中，如果加了这个关键字，重启之后，以上设置仍然会有效。
我是选择了第三种方法，执行之后，就可以正常的 export 了 。试过用第二种办法去重新挂载磁盘，但是总挂不成功，不知道是哪里做错了，，这里就不多说了。

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),
