Script de ejemplo createuser-ora-xstream.sql

Copie este script y sustituya los valores entre corchetes. Ejecute el script de ejemplo createuser-ora-nodba.sql antes de ejecutar createuser-ora-xstream.sql. Si configura Data Replication para utilizar una captura local donde los registros se procesan en la misma base de datos que los esquemas que replica, ejecute createuser-ora-nodba.sql y createuser-ora-xstream.sql en la misma base de datos y utilice el mismo valor para <user>. Si prefiere tener registros de proceso de Oracle XStream en una base de datos separada de los esquemas que replica, especifique opcionalmente un usuario diferente y ejecute el script en la base de datos.

-- This script is a continuation of createuser-ora-nodba.sql script with
-- additional changes needed for data replication user as well as XStream Log
-- Processing Database user. Process all needed privileges from the script
-- createuser-ora-nodba.sql prior to continuing with this script.

-- XStream privileges on data replication User

-- Expected to be used for DBMS_CAPTURE_ADM.BUILD
-- to define XStream Capture initialization points

grant execute on DBMS_CAPTURE_ADM to <user>;

-- Optional privilege that is expected to be used on
-- the target engine required for Recursion Prevention
-- in Bidirectional replication.

grant execute on DBMS_XSTREAM_ADM to <user>;

-- Enable enable_goldengate_replication

-- You need to set the enable_goldengate_replication system parameter on your source
-- database to enable XStream replication capability in Oracle.

ALTER SYSTEM SET enable_goldengate_replication=TRUE SCOPE=BOTH;

-- to enable the enable_goldengate_replication system parameter.
-- All instances in Oracle RAC must have the same setting. Refer to Oracle documentation
-- for further understanding on the impact of enabling this parameter on your database.

-- Setting up Oracle XStream user account.

-- Most work in data replication is done using the Oracle user account.
-- When data replication needs to interact with Oracle XStream it will use the Oracle XStream account.
-- An Oracle XStream account needs sufficient privileges to comply with Oracle XStream user requirements.
-- In a Pluggable database environment, the Oracle user account has all the granted access to the
-- Pluggable database when replication is configured for a pluggable database, whereas the XStream
-- user account has to be defined in the root container database as per Oracle XStream requirements.
-- All Oracle XStream related objects are defined and managed in the container database in this case.

CALL DBMS_XSTREAM_AUTH.GRANT_ADMIN_PRIVILEGE(
  grantee                 => <Log Processing Database User>,

1. Configure la base de datos de proceso de registro. Cuando crea un activo de Data Replication , se le solicita el nombre de la base de datos de proceso de registro de Oracle que desea que utilice Data Replication . Esta base de datos sirve una base de datos de salida XStream a la que Data Replication se conecta y se conecta para procesar registros de cambios lógicos proporcionados por la API XStream de Oracle . Para la captura local de Oracle XStream y el servidor de salida, esta es la misma base de datos que antes. Para bases de datos conectables, la base de datos de proceso de registro es la base de datos de contenedor raíz. Para la captura en sentido descendente, la base de datos de proceso de registro es la base de datos en sentido descendente. La base de datos de proceso de registro también requiere enable_goldengate_replication.

2. Opcional: Configure una base de datos de proceso de registro en sentido descendente. Se necesitan varios pasos para configurar la captura en sentido descendente en tiempo real o la captura en sentido descendente de registro de archivado. Revise la documentación de Oracle XStream para configurar los enlaces de base de datos y la transferencia de archivos de registro.

3. Configure la cuenta de usuario de Oracle XStream. La mayor parte del trabajo en Data Replication se realiza utilizando la cuenta de usuario de Oracle . Cuando Data Replication necesita interactuar con Oracle XStream, utiliza la cuenta de Oracle XStream. Una cuenta de XStream de Oracle necesita privilegios suficientes para cumplir con los requisitos de usuario de XStream de Oracle . En un entorno de base de datos conectable, la cuenta de usuario de Oracle tiene todo el acceso otorgado a la base de datos conectable cuando la réplica está configurada para una base de datos conectable. Sin embargo, la cuenta de usuario de XStream debe estar definida en la base de datos del contenedor raíz de acuerdo con los requisitos de Oracle XStream. Todos los componentes relacionados con Oracle XStream se definen y gestionan en la base de datos del contenedor raíz en este caso. Puede utilizar DBMS_XSTREAM_AUTH.GRANT_ADMIN_PRIVILEGE para otorgar privilegios de cuenta de usuario de XStream. Las credenciales de base de datos de salida de Oracle XStream distinguen entre mayúsculas y minúsculas. Para más información, consulte la documentaciónOracle.

4. Cree un esquema o elija un esquema existente para las tablas de metadatos de la base de datos. Debe especificar este esquema cuando configure Data Replication.
