Linux Informix如何進行數據庫復制

在Linux上使用Informix數據庫進行復制，通常涉及以下幾個步驟：

1. 準備工作

• 確保版本兼容性：確保源數據庫和目標數據庫的Informix版本兼容。
• 網絡配置：確保源數據庫和目標數據庫之間的網絡連接正常。
• 權限設置：確保執行復制操作的用戶具有足夠的權限。

2. 配置源數據庫

2.1 創建復制用戶

在源數據庫上創建一個用于復制的用戶，并授予必要的權限。

CREATE USER replicator IDENTIFIED BY 'password';
GRANT REPLICATION TO replicator;

2.2 配置日志文件

確保源數據庫的日志文件配置正確，以便能夠捕獲所有更改。

ALTER DATABASE <database_name> SET LOGFILE ON;

3. 配置目標數據庫

3.1 創建目標數據庫

在目標服務器上創建一個新的數據庫，用于接收復制的數據。

CREATE DATABASE <target_database_name>;

3.2 配置復制參數

在目標數據庫上配置復制參數，包括源數據庫的連接信息和復制策略。

CREATE DATABASE <target_database_name> USING
(
    NAME = <target_database_name>,
    LOGFILE = /path/to/target/logfile.log,
