F5-TTS Model Installation on Windows - Easy Step by Step Tutorial

Oracle GoldenGate 19c (19.1.0) is a powerful, high-performance software solution for real-time transactional change data capture (CDC), transformation, and delivery across heterogeneous databases and platforms. It enables zero-downtime migrations, high availability, data integration, and real-time analytics by replicating committed transactions with low latency while maintaining data integrity.

Whether you're synchronizing data between on-premises Oracle databases, moving to the cloud, or feeding data lakes, GoldenGate 19c excels in bidirectional replication, active-active configurations, and support for diverse targets like MySQL, SQL Server, Big Data platforms, and more.

Key Features and Enhancements in GoldenGate 19c

• Microservices Architecture (MA): Modern REST API-driven design with web-based management, improved security, and easier scalability (Classic Architecture is still available in 19c but Microservices is recommended for new deployments).
• Oracle Database 19c Support and broader heterogeneous capabilities (MySQL 8.0, cross-endian support, etc.).
• Enhanced Security: Centralized key management, SSL, encryption, and target-initiated distribution paths.
• Performance & Reliability: Parallel processing, schema change tracking, long-running transaction monitoring, and low-impact capture.
• Use Cases: Real-time data warehousing, disaster recovery, data synchronization, ETL/ELT, and event-driven architectures.

Prerequisites

• Source and target databases in ARCHIVELOG mode.
• Supplemental logging and forced logging enabled.
• Adequate CPU, memory, and disk space.
• Oracle GoldenGate software downloaded from Oracle Software Delivery Cloud.

Installation Steps (Silent Mode Example on Linux)

1. Unzip the software:
   

   unzip fbo_ggs_Linux_x64_shiphome.zip -d /u01/app/oracle/gg19c

2. Create a response file (oggcore.rsp):
   

   INSTALL_OPTION=ORA19c
   SOFTWARE_LOCATION=/u01/app/oracle/product/gg19c
   UNIX_GROUP_NAME=oinstall
   INVENTORY_LOCATION=/u01/app/oraInventory

3. Run silent installation:
   

   cd /u01/app/oracle/gg19c/Disk1
   ./runInstaller -silent -responseFile /path/to/oggcore.rsp -waitforcompletion

Initial Configuration (Source Database)

-- Enable archive log and supplemental logging
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION=TRUE SCOPE=BOTH;

-- Create GoldenGate user
CREATE USER c##ggadmin IDENTIFIED BY password CONTAINER=ALL;
GRANT DBA, CONNECT, RESOURCE TO c##ggadmin CONTAINER=ALL;
GRANT UNLIMITED TABLESPACE TO c##ggadmin;

Enable schema-level supplemental logging:

ADD SCHEMATRANDATA schema_name ALLCOLS

GGSCI Commands

cd $GG_HOME
./ggsci

Common GGSCI Commands:

INFO MANAGER
START MANAGER
STOP MANAGER

-- Create Extract
ADD EXTRACT ext1, TRANLOG, BEGIN NOW
ADD EXTTRAIL /u01/app/oracle/gg19c/dirdat/lt, EXTRACT ext1

-- Create Data Pump (optional)
ADD EXTRACT pump1, EXTTRAILSOURCE /u01/app/oracle/gg19c/dirdat/lt
ADD RMTTRAIL /u01/app/oracle/gg19c/dirdat/rt, EXTRACT pump1

-- Create Replicat
ADD REPLICAT rep1, EXTTRAIL /u01/app/oracle/gg19c/dirdat/rt

Example Extract Parameter File (ext1.prm):

EXTRACT ext1
USERID c##ggadmin@source, PASSWORD password
EXTTRAIL /u01/app/oracle/gg19c/dirdat/lt
TABLE schema_name.*;

Monitoring Commands

INFO ALL
STATUS EXTRACT ext1
STATS REPLICAT rep1
LAG EXTRACT *

Best Practices

• Use dedicated tablespaces and users for GoldenGate.
• Add checkpoint table: ADD CHECKPOINTTABLE
• Monitor lag and trail files regularly.
• Enable parallelism for high volume.
• Test failover and conflict resolution.

Troubleshooting Tips

• Check report files in dirrpt/ folder.
• Use SEND EXTRACT ext1, STATUS or VIEW REPORT
• Common issues: Missing supplemental logging, wrong credentials, network blocks.

Conclusion

Oracle GoldenGate 19c remains one of the best solutions for real-time, low-latency data replication. Start with a simple unidirectional setup and then scale up according to your needs.
