What is Oracle GoldenGate?
Oracle GoldenGate 12c enables the continuous, real-time capture, routing, transformation, and delivery of transactional data across heterogeneous environments. As new or updated data is committed at the source system, it is continuously captured and applied to one or more target systems with low latency.
Oracle GoldenGate Architecture
Oracle GoldenGate can be configured for the following purposes:
- A static extraction of data records from one database and the loading of those records to another database.
- Continuous extraction and replication of transactional Data Manipulation Language (DML) operations and data definition language (DDL) changes (for supported databases) to keep source and target data consistent.
- Extraction from a database and replication to a file outside the database.
Oracle GoldenGate is composed of the following components:
- Extract
- Data pump
- Replicat
- Trails or extract files
- Checkpoints
- Manager
- Collector
Commit Sequence Number (CSN)
When working with Oracle GoldenGate, you might need to refer to a Commit Sequence Number, or CSN. A CSN is an identifier that Oracle GoldenGate constructs to identify a transaction for the purpose of maintaining transactional consistency and data integrity. It uniquely identifies a point in time in which a transaction commits to the database.
The CSN can be required to position Extract in the transaction log, to reposition Replicat in the trail, or for other purposes. It is returned by some conversion functions and is included in reports and certain GGSCI output.
What Are The Prerequisites To Learn Oracle GoldenGate?

Oracle GoldenGate 12c Advance
- Accessing knowledge Documents – Mailing lists, Oracle GoldenGate forums, etc.
- Consulting the Documentation
- Getting familiar with the ShowSyntax parameter
- Getting familiar with the logdump utility
- Getting familiar with basic problems
- Developing the ability to deal with Extract and Replicatstartup issues
- Verifying file names, file permissions, consistency between Extract and Replicat group names and their supporting files
- Verifying consistent naming convention when defining trail files and their reference in the Extract/Replicat parameter files
- Verifying that the correct software version has been installed
- Verifying that the Oracle GoldenGate manager is running, that the group name which fails to start exists and is not misspelt
- Verifying that the the parameter file exists, has the same name as the Extract/Replicat group, and is accessible by Oracle GoldenGate
- Introducing the use of CHECKPARAMS to verify that the parameter syntax is correct
- Developing the ability to deal with and troubleshoot data extraction issues:Extract is slow – Extract abends – Data pump abends
- Analyzing various causes of a slow Extract startup
- Tracing may be enabled, activity logging may be enabled, many columns listed in tables being replicated
- Introducing the use of the CacheMgr parameter to control the virtual memory and temporary disk space that are available for caching uncommitted transaction data
- In-depth analysis of abending Extracts: is Extract unable to open the transaction logs? – Checking to see if the disk is full -Is an archive log missing?
- In-depth analysis of abending data pumps: Does the data pump abend with error number 509 (“Incompatible record”)?Have the source tables been changed? Is the Extract abending due to data manipulation?
- Was the primary Extract or the data pump stopped, re-added, or restarted without resetting the data pump’s read position in the local trail?
- Developing the ability to deal with and troubleshoot data replication issues:
- Analyzing the various causes of a “stuck” Replicat: Does “Stats Replicat” return no statistics? Do successive “Info Replicat” commands indicate that the Replicat read checkpoint is not moving?
- Verifying that the Replicat is reading the trail to which Extract is writing
- Analyzing the reasons why a Replicat abends: Is Replicat unable to locate a trail? Is Replicat unable to open a trail file? Was “Add TranData” issued for each table?
- Developing the ability to deal with and troubleshoot missed transactions involving issues such as: Tables that are not properly specified – Missing” Add TranData” command – LOB data not replicating
- Analyzing the reasons why transactions are not being processed: Were the tables included in Table and Map statements? Are fully qualified names (owner.table) used for both Table and Map?
- ‘Single quotes’ on object names imply case-sensitive names for some databases (including the Oracle database)
- Are the transactions coming out of the source system properly?
- Developing the ability to deal with and troubleshoot mapping problems, such us: Fetching from the source data fails – Table and column names not matching between the source and the target
- Analyzing the causes of various mapping problems:Is Extract returning fetch-related errors? Was the row containing the data deleted?
- Has the undo retention expired?
- Is “NoUseLatestVersion” for “FetchOptions” being used?
- Do the source and target tables exist in the databases? Are they specified correctly in the Table or Map statement? Are their names fully qualified (schema.table)?
- Do table and column names contain only supported characters?
- Are WHERE clauses comparing different data types?
- Is KeyCols being used? Are both source and target KeyCols being used? Corresponding source and target columns must match.
- Developing the ability to deal with and troubleshoot :
- SQLEXEC problems – File-maintenance problems – Time differences – Too many open cursors
- File-Maintenance Problems: Discard File Is Not Created – Discard File Is Too Big – Trail File Is Too Big
- Miscellaneous Problems: Time Differences – INFO Command Shows Incorrect Status
