DB2入门（5）——DB2配置文件

那我想要了解DB2中的一些参数，所以想看看db2的配置文件，类似于mysql中的my.cnf,postgresql中的postgresql.conf的地位的文件。

参考文章1：DB2数据库日志目录重要配置文件说明

DB2数据库日志目录重要配置文件说明

1.SQLDBCONF :数据库参数配置文件，使用 get db cfg/update db cfg 读取和修改数据。

2.SQLBP.*:缓冲池控制文件，使用 alter bufferpool 控制。

3.SQLSPCS.*:表空间控制文件，使用list/alter tablespace控制。

4.db2rhist.asc:数据库历史文件，使用LIST HISTORY浏览。

SQLOGCTL.LFH.*:数据库日志控制文件，无法浏览或人工修改。

参考文章2：DB2配置

DB2可以在四个不同层面配置：

1.系统环境变量（System Environment Variable）

系统环境变量用来配置DB2的使用环境：

[db2inst1@localhost NODE0000]$ set | grep DB2
DB2DIR=/opt/ibm/db2/V11.1   --DB2的安装目录
DB2INSTANCE=db2inst1         --当前活动的实例
DB2LIB=/home/db2inst1/sqllib/lib
DB2_HOME=/home/db2inst1/sqllib
DB2_NET_CLIENT_PATH=

DB2INSTANCE环境变量介绍：
如果一个系统中有多个实例，那么如何在各个实例之间进行切换以及如何同时启动多个实例呢？这就需要DB2INSTANCE环境变量。环境变量是操作系统层面的，是在操作系统级别上定义的变量。最常使用的DB2环境变量是DB2INSTANCE。该环境变量运行您指定当前活动实例，所有命令都将 应用于该实例。

配置实例
每个实例创建后，都有一个实例配置文件（db2system）,这个实例配置文件控制实例的安全、通信、管理和资源的分配。我们可以根据需要来查看、更改和复位这个配置参数。这个配置文件是二进制的，只能通过命令来修改。
可以使用db2 get dbm cfg命令来查看当前实例配置参数。

db2 get dbm cfg命令显示的是在安装产品期间指定为默认配置参数的当前值，或在先前更新配置参数期间指定的那些值。
可以使用db2 update dbm cfg using ..来更新实例配置文件。

2.DB2概要文件注册表（profile registry）

有两种DB2概要文件注册表变量，一种是全局概要文件注册表变量，另一种是实例概要文件注册表变量。全局概要文件注册表变量影响所有的实例，实例概要文件注册表变量只影响特定的实例。它们的名称是相同的。DB2使用db2set命令来管理这些变量。DB2概要文件注册表非常多，但我们通常设置的却常少，如下：

    显示所有DB2概要文件注册表变量：db2set -lr  
    显示当前设置的所有DB2概要文件注册表变量：db2set -all  
    帮助：db2set -?  
    设置变量：db2set =  


    常用的DB2概要文件注册表变量  
    DB2COMM  
    DB2SYSTEM  
    DB2INSTDEF  
    DB2ADMINSERVER  

• DB2 全局注册变量参数DB2ADMINSERVER定义了管理DB2数据库服务器的DAS（Database Administration Server）：

[db2inst1@localhost NODE0000]$ db2set -all | grep ADMINSERVER
[g] DB2ADMINSERVER=db2dasusr1

要启动或停止DAS，使用命令

db2admin start|stop

配置管理服务器：
查看：

[db2inst1@localhost NODE0000]$ db2 get admin cfg

更新：

3.数据库管理器配置（Database Manager Configuration）

以下参数用来配置实例：

查询命令：db2 get dbm cfg

设置命令：db2 update dbm cfg using
