GoldenGate (GG) is being used by the utility company I work
for in various areas.
Data Analytics is the main use of GG at the moment. Normally, the sheer level of database hits
required by our daily Business Intelligence reports would place a heavy burden on
the disk groups in our core ASM; however, with GG, we are able to seamlessly
replicate that data in real-time into a separate database using separate
resources. By doing this, we are able to
alleviate potential bandwidth issues posed by our BI group’s database querying. It should be noted that GG does not require
all tables to be replicated: we only replicate under 100 of the thousands of
tables in the main databases. Our GG
database is not normalized, so we are essentially combining disparate databases
into one, which has its advantages and disadvantages.
Another use we currently have for GoldenGate is on a
large project level. As part of a data
conversion effort, we are using GoldenGate to replicate data into a separate
database in real-time. This will allow
us to save 12+ hours during our conversion, as well will not need to execute an
RMAN backup in order to move data into our target database. In other words, we are directly replicating
data into our target database, so right when we are ready to switch
servers/databases for the go-live of our project, we will be ready to
immediately start to convert data.
- Replicates data without "missing" items. This is key, as there was initial concern that with the amount of tables and columns involved, certain items were bound to be "missed", though we have not seen this (outside of an anomalous server crash incident that wasn't due to GG).
- Replicates data in real-time. Proof of concept for GG was intuitive for end users, as the data is immediately available. There are no "jobs" or "interfaces" that need to be run: the data is immediately available on the target database for viewing
- GG is able to modify data "in transit", which can save loads of time if you were to need to instead modify large amounts of data after it is synchronized to the target database. As one would expect, this is seamless with low complexity modification, by can become untenable with larger blocks of data (e.g. CLOBs).
- GG can sometimes lag behind in synching large objects (i.e. CLOBs and BLOBs) on tables, which is odd because we are using GG on an Oracle database with an Oracle software suite. It's definitely possible to use GG on non-LOB columns, and we do, but it is best used for non-LOB columns, just based on personal experience.
- When using GG, it is key to separate the replicat groups into manageable sizes. This can be somewhat burdensome, as maintenance will increase with each new replicat group. If tables are large enough, they need to essentially be their own group.
- Sometimes, replicat groups need to be grouped by parent and child (if using in a normalized db). This again increases maintenance due to more groups existing. This will be especially true for large tables that are partitioned with foreign key constraints on child tables.

We use Oracle GoldenGate 19c in our critical business databases, to replicate the databases between datacenter from different cities. This is a part of our business continuity program. We use asynchronous replication since is a big amount of data that have to travel through the network specially from our data warehouse database.
- Synchronous data replication.
- Asynchronous data replication.
- Configuration of time replication.
- When you activate the synchronous replication the performance of the server goes down.
- The pricing is expensive.
- The configuration take some time to be done.
- The compression ratio of the data that travels through network could be better.

Oracle GoldenGate is being used by the departments as required and as needed. Especially we used for migration purpose. We are migrating the databases from on-premises to Cloud. The real problem is to complete the migration with zero-downtime. We need a revert plan (rollback strategy) when it fails. [Oracle] GoldenGate helped a lot in completing this migration task with Zero-downtime. [Oracle GoldenGate] is real-time data capture, continuous delivery of transaction data across different sources.
- OGG can be used and integrated with heterogeneous databases as well as homogeneous databases.
- OGG is easy setup as well as easy learning curve
- OGG supports large databases
- OGG support many uses cases (topologies) such as unidirectional replication, bidirectional, peer-to-peer, Broadcast, Cascading replication etc.
- OGG can be used not only for CDC (change capture), can be used to full load
- Expensive
- Require resources such as OGG script developer and SME

Our company in EMEA region has two data centers, working in the Active/Passive(standing by) mode. We use Oracle GoldenGate to "clone" the live data transactions from the master database (which resides in the currently active data center) to the standing-by database (which is in the limited read-only mode, and resides in our passive data center). If the active DC is down and DR is required, the standing-by database in the passive DC will be promoted to the master one which can take R/W transactions, and the OGG will reverse the uni-direction data copy. This pattern is applied on all business critical IT application's DB instances.
- As the product under the Oracle umbrella, it perfectly and natively supports the Oracle database very well.
- For the standard scenario and use cases, the configuration is straight-forward (in our case uni-direction copy from source to target).
- It is robust and the performance meets our SLA, even for a large amount of data volume.
- The error report is not only detailed but hits the right points, so trouble shooting is easy.
- The metrics UI is another product that should be purchased separately, with high price, we use open source Grafana as a replacement.
- Documentation can be improved. Sometimes [it is] not so easy to find the correct information quickly.

We implemented Oracle GoldenGate on at least 400 database environments. We have a large infrastructure with tons of applications to assign installation and repair jobs to field technicians. In some of the applications, we can't afford latency or replication errors. GoldenGate has been a great tool.
- I was able to find what I needed, but it took longer than I think it needed to. The system was navigable, but not until I had training on it. Before that I was clueless on how to find anything.
- It allows the replication in real time from the Oracle database in RAC to the contingency database, through the immediate replication of the data in the redo logs, without the need to wait for them to be written at the level of the archive logs.
- You can have multiple different data sources coming into this Oracle GoldenGate. You are not limited to only Oracle databases.
- The time that it takes to implement Oracle GoldenGate. Because you can have multiple databases going through it it can take a long time to set it up.
- It was more complicated than it needed to be. Without the training I feel that it isn't intuitive. I think maybe the structure should be reinvented so that it is more intuitive.
- GoldenGate replication is only for databases, it would be nice to use it across file and folders

Oracle GoldenGate is used in a traditional manner for homogeneous data replication between production and non-production environments. This allows the different environments to be utilized for different purposes with the same source data. Some environments are for real-time data analysis while others are backend reporting and analysis.
Oracle GoldenGate allows us to split highly responsive, mission critical systems from lower environments while retaining clean copies of source data.
Oracle GoldenGate allows us to split highly responsive, mission critical systems from lower environments while retaining clean copies of source data.
- Integrates with Oracle databases and Oracle database servers (particularly exadata - engineered systems)
- Easy to define source and destination data attributes and configuration
- Robust error reporting
- More integration with traditional Oracle products such as SQL*plus
- GUI
- More transparent integration with OEM
- More standard error reporting similar to traditional Oracle products

Currently [Oracle] GoldenGate is being used to replicate a backup database for disaster recovery and also integrating different data sources to a single database.
- Documentation is easy to follow
- Downtime seems very minimal
- Able replicate in real-time
- Expensive, considering we were going to use Active Data Guard.
- A lot of memory is being used.
- No UI

It's used by our Computer Services Department to create reporting databases as well as for DR. The replication is unidirectional and replicates data in four non-production environments. This enables us to perform long-running queries without affecting the performance of our production systems. We have a lot of clients using it. It can migrate data between databases in realtime.
- Flexibility to migrate data.
- Fast transactions between source and target databases .
- Easy to analyze problems when occur.
- Good for disaster recovery and data protection database.
- Oracle GoldenGate Studio is expensive, and you can use Grafana instead.
- Character set problems when migrating database.
- In-house
Oracle GoldenGate is being used by our core software development team. We are using it as a real-time data replication solution to achieve high availability/disaster recovery for our data, to prepare a read-replica database to offload query-based requests, and to perform real-time business intelligence related operations on our synced data.
- No Downtime during System Migration. Replicating data onto other servers in preparation for a system migration does not result in any downtime.
- Initial setup of Oracle GoldenGate is easy and straightforward. Instructions are precise and simple to follow.
- Thorough and Insightful Documentation. All troubleshooting and tuning issues are well-known by the community, and hence are well-documented online.
- Lack of Simple UI for Non-Technical Users. It would be nice to have an option to toggle simpler, and less advanced options to make it easier for non-technical users to understand what Oracle GoldenGate is.
- Lack of Variety of Performance Metrics. Would prefer more detailed performance metrics to be offered out-of-the-box.
- Some Features Won't Always Run as Expected. We have sometimes faced issues when features don't run as they are used to. They will be working at times, but there is the occasional failure in streaming.

We use it for our core system to support our main database for courier services. The core system is used by all of the operations and sales teams, as well as the Board of Directors. All of the transactions should be backed up and maintained in our backup servers as well as our disaster recovery. We use GoldenGate to replicate our database.
- Oracle GoldenGate has been able to replicate all of our data in different servers and locations.
- It also supports large databases
- It supports a high volume of daily transactions of our sales.
- In certain cases, we consider how well GoldenGate is able to help us interconnect our main database directly to our backup system (we use actifio for it).
- We have some difficulties to cut-off our size of main database, so maybe Oracle GoldenGate could make it easier by providing a function to shrink our data safely.
- We also interconnected with our partners to share some data, specific and limited fields only, through third party services, using messaging system (ISO 8583, XML and JSON). It would be great if GoldenGate also provided such a function.

We are using OGG to synchronize our UAT/Production database with Oracle Cloud. The set up is being done by administrators and used only by the channels manager and administrator. One of the problems we found is the product cost, specifically after moving from Oracle Classic to OCI. In addition, we didn't find clear documentation to describe what we exactly can do with sequences synchronization. The user interface is another product and we have to purchase it to be able to monitor GG performance and issues.
- Initiating integration and configuring source and target is easy.
- Easy integration with different types of DB.
- Availability to synchronize specific tables/DB schemas.
- No clear documentation for some points like sequence synchronization.

We have multiple data centers and all of them share the same copy of DB. We use GoldenGate to do cross datacenters replication for Oracle and My SQL DBs as an HA solution. As our DBs are one of the busiest in the world and have a very tight SLA for replication lag which we can achieve by GoldenGate. We have explored few other products like SharePlex but GG done the work for us. GoldenGate is a de-facto standard for replication in our organization.
- GoldenGate is tightly integrated with Oracle databases and supports all features like encryption, LOBs, compressions etc.
- GoldenGate is very flexible, you can customize it as per your requirement. Whether it is high transaction DB or a DR site, it can work anywhere.
- We can dump data in multiple formats with big data adaptor like kafka, hdfs, xml etc.
- We can achieve high throughput by splitting extracts and replicats. Also from integrated capture and replication it is so smart that it spawn parallel process based on the load.
- Goldengate is very useful in cross platform migration.
- Memory consumption of extract is exponentially high, sometimes extract restart consumes so much memory that it impact the current application connections.
- There are so many bugs in the system for dumping data via xml or other format like hdfs. Data corruption is so frequent that we wrote our own scripts to detect and repair xml corruption. As always we didn't get proper support from Oracle on this issue.
- For active-active replication on busy systems, online DDL change can sometimes cause data discrepancy.
- With integrated capture creating index on big table is a headache even thought you are creating with via gg user. Extract starts get lagging even after skipping the DDL by gg user in param file. This was not the case with classic capture.

Yes - I am a member of the India OAUG.
There are many meetups organized by Oracle GoldenGate developers and users. At least every quarter there will be one hosted in one of the customer sites where people share their experience and feedback on the use of Oracle GoldenGate. Also I have attended IOUG conference where you can discuss issues and new features.

We use GoldenGate to sync up data from our customer and care system to Oracle Analytics Database
- When it works, it works great
- Whenever we have to do a data subset from prod to lower environments its almost impossible for GG to find its checkpoint... we had lots of difficulty with restarting GG process after the refresh.

Oracle GoldenGate is used widely across the organization. We use it for heterogeneous replication, active-active and active hot standby, and offloading reporting.
- Oracle's new AutoCDR (conflict detection and resolution) feature makes setting up active-active replication fairly easy. We were able to setup active-active replication using the AutoCDR feature in a very short time.
- We had plans for separating reporting and ingestion from our primary DW system. This system generates an excess of 1TB of redo during ingestion. GoldenGates coordinated replicate helped us achieve this almost impossible task with ease.
- In my previous workplace, for a large telecom company, we had to publish data from the store of records as a service. We used GoldenGate BigData adapters to replicate data to a Kafka endpoint.
- For quick application failovers, we use GoldenGate Active-Passive replication with connection failover defined in the WebLogic connection settings.
- There are certain challenges using the product when the redo generation is in excess of about 120G per hour.
- For large transaction (more than 10 million records per commit), extract get slower. Some other replication tools do such activities better.
- Ability to recreate large transaction without breaking the transaction into individual statements may help. There are ways to make this transaction faster, but having the ability to replicate a statement as it was issued on the source may be helpful in some cases.

We use it to move data between databases to a dw for reporting purposes. We also use it to transform data as it moves, and we use it to populate pdb's to enable our services architecture.
- GoldenGate, using CDC, moves data between databases and database technologies to enable near real-time propagation.
- GoldenGate can transform data as it moves from tables in the same or different databases.
- GoldenGate can move data between database platforms.
- We need more rapid support for bug mitigation.
- GoldenGate's API needs to allow for streaming from Oracle's cloud databases where we don't have access to the OS.

We use GoldenGate to replicate some of the data from the production database to a data warehouse. It is used by the IT department. By using GoldenGate we don't impact the production database. We can run queries or reports or any long queries from the replicated database using GoldenGate. At one time we even used GoldenGate as a DR database and replicated entire production database. By doing so, one time when we had an outage and lost the production database, this DR became available to us and switched it to the primary. So we have a lot of advantages when using GoldenGate. We can replicate some tables or all tables and different scenarios of replicating data using functions and triggers. The business problem it addressed was less impact on production databases, more realtime data available to the business without putting an overload on production databases.
- Realtime replication and zero data loss.
- Less lag and more reliable.
- No downtime for our primary database.
- GUI could use a little improvement.

GoldenGate is being used as a DR solution and as well as a method for replicating from a transactional to reporting DB. It is used across the whole organization. It addresses a need for disaster recovery on different data centers including the cloud.
- Replication of data.
- Easy of set up.
- Notification of status.
- Improvement of collision management.

We use Oracle GoldenGate for multiple reasons such as data replication, to maintain active/active databases for critical applications and not but least for database migration with zero downtime. We're happy with the usage and its purposes. It is being used across the whole organization. We use OEM monitoring to alert the monitoring team when there is a lag on the DB sync.
- Data replication to keep our data up-to-date and used for reporting purposes.
- Data migration with zero downtime.
- Data sync between two data centers to keep the system active/active with load balancing.
- We're facing issues during bi-directional replication. The detailed data quality issues alerts may be helpful.

We have built a data change pipeline using GG technology by plugging in Kafka in front. Also, it's helped us in fault tolerance as a live DR database is readily available in a separate DC in case current DC goes down. In both modes, it's been super helpful to ensure data is sent in an async manner to reporting systems. It's saved us in cases of DC failures.
- Data replication in real-time.
- Fault tolerance.
- No data loss.
- Better documentation would be appreciated.

It is being used by an existing product in one of the business units which supports the payment platform. We are also planning to use it for a new application pipeline which is currently under development using bi-directional replication.
- The unidirectional and bidirectional capability of data replication.
- Data quality assurance including both DDL & DML replication.
- Validation and data quality measurement facility available through Veridata.
- Also helps in zero downtime based migration.
- The data validation functionality is built-in and part of auto configuration instead of a separately licensed product.

We have been using Oracle GoldenGate (OGG) for our replication needs. We have a mix of database environments including Oracle, DB2 and Microsoft SQL Server. We use Oracle GoldenGate to replicate across the mix of these different RDBMS. OGG is reliable, fast, has high throughput and allows heterogeneous replication.
We also use OGG Management Pack which is an extra license cost and includes Oracle GoldenGate Monitor, Oracle GoldenGate Director and Oracle GoldenGate Veridata.

- Supports both homogeneous and heterogeneous replications.
- Supports DDL replication if both source and target databases are Oracle.
- Supports multiple replication topology such as unidirectional, bi-directional, cascading, peer to peer and multicasting.
- Can interface with JMS and Big Data Systems.
- Like most Oracle products, it is quite expensive.
- Too many tables in single replication channels creates performance bottlenecks. You have to split your tables into multiple channels.

It is used by IT to sync data across databases. The source is our SQL Server database and the target is the Oracle database. The source database is outsourced to a third party and we use GoldenGate to sync the data to our local Oracle database. The main challenge we have is that GoldenGate can't replicate DDL among different RDBMS. We have had to stop and rebuild GoldenGate multiple times due to DDL change on the source side.
- Real Time Sync
- Less overhead
- Stable performance
- Should make the high availability easier to use. Not bound to only DBFS or ACFS.
- Need a powerful GUI tool to make the configuration easier.
- Could it be cheaper? Or have a basic free version?
- If it could support DDL among different RDBMS, that would be great.
Not yet, but I'm interested in Oracle user groups - I am not a member of a user group yet. May join in the future. Currently I am considering join both Oracle and MySQL groups to get updated with the most recent technologies. I am also interested on how Oracle and MySQL could be connected through GoldenGate. Since they are both from Oracle, I assume GoldenGate should be better integrated between them.
November 06, 2018
We use Oracle GoldenGate as a part of our high availability solution. The entire database is replicated in real time to other geographical facilities and makes the system available for 24/7.
- GoldenGate is good for real-time data replication.
- The database upgrade and migration was possible with zero downtime because of having GoldenGate in place.
- It also works with different databases other than Oracle
- The monitoring side could be improved with easy to use reporting.
