 1 初始化參數   
      alter system set aq_tm_processes=2 scope=both;
　　alter system set global_names=true scope=both;
　　alter system set job_queue_processes=10 scope=both;
　　alter system set parallel_max_servers=20 scope=both;
　　alter system set undo_retention=3600 scope=both;
　　alter system set nls_date_format='YYYY-MM-DD HH24:MI:SS' scope=spfile;
　　alter system set streams_pool_size=25M scope=spfile;
　　alter system set utl_file_dir='*' scope=spfile;
　　alter system set open_links=4 scope=spfile;

      alter system set log_archive_dest_1='LOCATION=d:/oracle/test' scope=both;

      alter system set log_archive_format='arch%t_%s_%r.arc'

 

  執行完畢後重啓數據庫

 

2 用 sqlplus / as sysdba 登錄

創建stream 表空間

create tablespace tbs_stream datafile 'D:/oracle/product/10.2.0/oradata/tx431/stream01.dbf' size 100M;

 

用戶

create user strmadmin identified by strmadmin default tablespace tbs_stream temporary tablespace temp;

授權

grant connect,resource,dba,aq_administrator_role to strmadmin;

 begin
    dbms_streams_auth.grant_admin_privilege(
   grantee => 'strmadmin',
    grant_privileges => true);
    end;

 

#查看是否歸檔，stream 主要是獲取日誌 然後解析

驗證是否歸檔：
SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination          d:/oracle/test 

Oldest online log sequence     2662
Next log sequence to archive   2679
Current log sequence           2679

#如果歸檔就不用做下面的

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.

#創建dblink 需要用strmadmin登錄

 sz431 需要和global_name 前面一樣 後面150sz431
create database link sz431 connect to strmadmin identified by strmadmin using '150sz431'
create database link tx431 connect to strmadmin identified by strmadmin using '96tx431'
