Oracle Streams Asenkron Kullanım

Eğer asenkron kullanacaksak bu iki şekilde yapabiliyoruz

1. Asynchronous Distribution HotLog

2. Asynchronous AutoLog

Bazı adımlar şöyle

-- Publisher : Create the Change Sources
BEGIN
   DBMS_CDC_PUBLISH.CREATE_HOTLOG_CHANGE_SOURCE(
       change_source_name => 'MAILING_LIST',
       description => 'test source',
       source_database => 'source_db');
END;
/

-- Publisher : Create Change Sets
BEGIN
   DBMS_CDC_PUBLISH.CREATE_CHANGE_SET(
       change_set_name => 'DAILY_MAILING_LIST',
       description => 'change set for contact info',
       change_source_name => 'MAILING_LIST',
       stop_on_ddl => 'y');
END;
/
-- Publisher: Create the Change Tables
BEGIN
   DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE(
       owner             => 'staging_streamspub',
       change_table_name => 'contacts_ct',
       change_set_name   => 'DAILY_MAILING_LIST',
       source_schema     => 'SH',
       source_table      => 'CONTACTS',
       column_type_list  => 'PHONE_NUMBER NUMBER(10), CONTACT_NAME VARCHAR2(50),
          ZIP_CODE NUMBER(5),
          EMAIL_ADDRESS VARCHAR2(15), HOME_ADDRESS VARCHAR(20)',
       capture_values    => 'both',
       rs_id             => 'y',
       row_id            => 'n',
       user_id           => 'n',
       timestamp         => 'n',
       object_id         => 'n',
       source_colmap     => 'n',
       target_colmap     => 'y',
       options_string    => 'TABLESPACE TS_DAILY_MAILING_LIST');
END;
/
--Publisher: Enable the Change Source
BEGIN
  DBMS_CDC_PUBLISH.ALTER_HOTLOG_CHANGE_SOURCE(
    change_source_name => 'DAILY_MAILING_LIST',
    enable_source      => 'Y');
END;
/

Publisher: Grant Access to Subscribers
GRANT SELECT ON staging_cdcpub.products_ct TO subscriber1;
