Additional Configurations for Preparing the Source Database for Online Migration

Before you can migrate data with Oracle Cloud Infrastructure Database Migration, perform additional configurations for your source database for online migration as described here.

  • To configure a single-tenant (Non CDB) as a source for online migration, run the following SQL commands:
-- Archive Log Mode
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;
 
-- Global Names
ALTER SYSTEM SET GLOBAL_NAMES=FALSE;
 
-- Stream Pool Size
ALTER SYSTEM SET STREAMS_POOL_SIZE=2G;
 
-- Force Logging
ALTER DATABASE FORCE LOGGING;
 
-- Enable GoldenGate
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION=TRUE;
 
-- Supplemental Logging
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
 
-- User system for Datapump
ALTER USER SYSTEM IDENTIFIED BY system_pwd ACCOUNT UNLOCK;
 
-- Create GoldenGate nonCDB user
CREATE TABLESPACE GG_ADMIN DATAFILE '+DATA/ggadmin_data.dbf' SIZE 100m AUTOEXTEND ON NEXT 100m;
CREATE USER GGADMIN IDENTIFIED BY ggadmin_pwd DEFAULT TABLESPACE GG_ADMIN TEMPORARY TABLESPACE TEMP QUOTA 100M ON GG_ADMIN;
GRANT CONNECT TO GGADMIN;
GRANT RESOURCE TO GGADMIN;
GRANT CREATE TO GGADMIN;
GRANT SELECT_CATALOG_ROLE TO GGADMIN;
GRANT DV_GOLDENGATE_ADMIN TO GGADMIN;
