如何配置Linux Informix数据库连接池

配置Linux Informix数据库连接池通常涉及以下几个步骤：

1. 安装Informix客户端软件

确保你已经在Linux系统上安装了Informix客户端软件。你可以从IBM官方网站下载并安装适合你系统的版本。

2. 配置环境变量

编辑你的shell配置文件（如.bashrc或.bash_profile），添加以下环境变量：

export INFORMIXDIR=/opt/informix
export LD_LIBRARY_PATH=$INFORMIXDIR/lib:$LD_LIBRARY_PATH
export CLASSPATH=$INFORMIXDIR/lib:$CLASSPATH

然后重新加载配置文件：

source ~/.bashrc

3. 创建连接池配置文件

在Informix客户端目录下创建一个连接池配置文件，例如pool.cfg。这个文件定义了连接池的参数。
