Script di esempio createuser-ora-xstream.sql

Copiare questo script e sostituire i valori tra parentesi angolari. Eseguire lo script di esempio createuser-ora-nodba.sql prima di eseguire createuser-ora-xstream.sql. Se si configura Data Replication per utilizzare una cattura locale in cui i log vengono elaborati nello stesso database degli schemi replicati, eseguire createuser-ora-nodba.sql e createuser-ora-xstream.sql sullo stesso database e utilizzare lo stesso valore per <user>. Se si preferisce avere i log del processo XStream di Oracle in un database separato dagli schemi replicati, specificare facoltativamente un utente differente ed eseguire lo script sul database.

-- 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

-- XStream privileges on data replication User

-- Expected to be used for DBMS_CAPTURE_ADM.BUILD

-- 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.

1. Configurare il database di elaborazione log. Quando si crea un asset Data Replication , viene richiesto il nome del database di elaborazione log Oracle che si desidera venga utilizzato da Data Replication . Questo database serve un database in uscita XStream a cui si connette Data Replication e si collega per elaborare i record di modifica logici forniti dall'API XStream Oracle . Per l'acquisizione XStream Oracle locale e il server in uscita, questo è lo stesso database di prima. Per i database collegabili, il database di elaborazione log è il database del contenitore root. Per l'acquisizione a valle, il database di elaborazione log è il database a valle. Il database di elaborazione log richiede anche enable_goldengate_replication.

2. Facoltativo: configurare un database di elaborazione log downstream. Sono necessari diversi passi per configurare l'acquisizione downstream in tempo reale o l'acquisizione downstream dei log di archivio. Consultare la documentazione XStream di Oracle per configurare i collegamenti del database e il trasferimento del file di log.

3. Impostare l'account utente Oracle XStream. La maggior parte delle operazioni in Data Replication viene eseguita utilizzando l'account utente Oracle . Quando Data Replication deve interagire con Oracle XStream, utilizza l'account Oracle XStream. Un account XStream Oracle necessita di privilegi sufficienti per soddisfare i requisiti dell'utente XStream Oracle . In un ambiente di database collegabile, l'account utente Oracle ha tutto l'accesso concesso al database collegabile quando la replica è configurata per un database collegabile. Tuttavia, l'account utente XStream deve essere definito nel database del contenitore root in conformità con i requisiti XStream di Oracle . In questo caso, tutti i componenti correlati a XStream di Oracle sono definiti e gestiti nel database del contenitore root. È possibile utilizzare DBMS_XSTREAM_AUTH.GRANT_ADMIN_PRIVILEGE per concedere i privilegi dell'account utente XStream. Le credenziali del database in uscita Oracle XStream sono sensibili al maiuscolo / minuscolo. Per ulteriori informazioni, consultare la documentazioneOracle.

4. Creare uno schema o scegliere uno schema esistente per le tabelle di metadati del database. È necessario specificare questo schema quando si configura Data Replication.
