Oracle oswatch工具简介，图形界面可以借助xmanger，如果服务器有图形界面那更好了，也可以生成报告！
oswatch（简称osw）是Oracle的一个操作系统监控工具，oswatch是一个轻量级的操作系统监控工具，通过调用系统的命令完成信息的收集，并形成历史数据，命令如下：ps ，top ，mpstat ，iostat，netstat ，，traceroute vmstat 。支持的操作系统有AIX ，Tru64 ，Solaris ，HP-UX ，Linux 。 可以在metlink直接下载：OS Watcher User Guide [ID 301137.1] （Metalink Note:301137.1） 下载的就是tar包，然后直接解压就可以使用的。osw是一个java应用，可以在服务器上运行。
注意：osw工具需要以root用户来操作哦！
1、安装部署（解压既可）
从上面看，权限有点怪，不过不管它，继续！
2、启动监控器
启动监控就是调用startOSW.sh脚本。
# ./startOSW.sh arg1 arg2
arg1：数据收集的间隔，以秒为单位。
arg2: 数据收集多长时间，以小时为单位。
例如：
以上这里就是没30秒采样一次，连续采用一个小时。初次使用会在OSW_HOME目录下面生成一个archive目录，此目录就是存放采样信息的：

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.
