  • 异构GoldenGate 12c 单向复制配置(支持DDL复制)

    1.开始配置OGG支持DDL复制(在source端操作)
        1.1 赋予权限
            SQL> conn /as sysdba
            已连接。
            SQL> grant execute on utl_file to ggs;
        
        1.2 修改全局配置文件添加ggschema
            GGSCI (WIN-GM5PVS1CILH) 18> edit param ./GLOBALS
            GGSCI (WIN-GM5PVS1CILH) 19> view param ./GLOBALS
            ggschema ggs
            GGSCI (WIN-GM5PVS1CILH) 20>
    
        1.3 运行相关sql脚本 及修改参数
    
            C:UsersAdministrator>cd C:ora11gproductogg_src
            C:ora11gproductogg_src>sqlplus /nolog
            SQL> conn /as sysdba

            SQL> @marker_setup.sql
            
            You will be prompted for the name of a schema for the Oracle GoldenGate database objects.
            NOTE: The schema must be created prior to running this script.
            NOTE: Stop all DDL replication before starting this installation.
    
            Enter Oracle GoldenGate schema name:ggs

    2.source端修改extract进程的params文件,添加"ddl include all"参数,重启extract进程        
        2.1 查看添加后的参数
            GGSCI (WIN-GM5PVS1CILH) 40> view param eora_t1
            extract eora_t1
            setenv (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)
            ddl include all
