Release 21c (21.1.0): Initial Release May 2021
- Oracle GoldenGate Microservices Architecture is available with Oracle and heterogeneous databases
-
Oracle GoldenGate 21c supports the following databases:
-
Oracle Database
-
DB2 z/OS
-
MySQL
-
SQL Server
-
- All Databases
- Oracle Database
-
- Unified Build Support
-
Oracle GoldenGate uses a single, unified build for capturing from and applying to multiple major Oracle Database versions for supported operating systems by including the latest Oracle database client libraries as part of Oracle GoldenGate.
- Automatic Extract of tables with supplemental logging is supported
- Oracle GoldenGate provides a new
auto_capture
mode to capture changes for all the tables that are enabled for logical replication. You can list the tables enabled for auto-capture using theLIST TABLES AUTO_CAPTURE
command option. Use theTRANLOGOPTIONS ENABLE_AUTO_CAPTURE
option to set up automatic capture.When this parameter is enabled in Extract, any table that has supplemental logging on it will be automatically captured by Extract and you don't need to add the table as a
TABLE
parameter. You can use the new DDL options forALTER TABLE ... ENABLE LOGICAL REPLICATION ALL KEYS
,ALTER TABLE ... ENABLE LOGICAL REPLICATION ALLOW NOVALIDATE KEYS
,CREATE TABLE ... ENABLE LOGICAL REPLICATION ALL KEYS
, orCREATE TABLE ... ENABLE LOGICAL REPLICATION NOVALIDATE KEYS
to add supplemental logging to a table and allow Oracle GoldenGate to automatically capture it. This also requires Oracle Database 21c and higher.
- Oracle native JSON datatype is supported
- Oracle GoldenGate capture and apply processes now support the new native JSON datatype, which is supported by Oracle Database 21c and higher.
- Automatic Conflict Detection and Resolution for Oracle Database 21c is available
-
This feature provides support in Oracle Database 21c and Oracle GoldenGate to enhance Automatic CDR to support:
-
Earliest timestamp resolution
-
Delete always win
-
Site priority resolution
These features can be enabled in the
DBMS_GOLDENGATE.ADD_AUTO_CDR
procedure. -
- Kerberos Authentication is supported
- Oracle
GoldenGate supports external authentication for database login
(
DBLOGIN
) for Kerberos user accounts.
- Oracle Cloud Infrastructure Key Management Service (OCI KMS) integration is available
-
Oracle GoldenGate supports integration with the OCI KMS for trail file encryption, which simplifies securing Oracle GoldenGate cloud deployments.
- Autonomous Database Extract is supported
- Oracle GoldenGate can now capture from the Autonomous Databases in OCI. This feature allows capturing data out of specific Autonomous environment in a secure way without allowing access to any other data in that shared environment. For additional details, see Capturing from Pluggable Databases in Using Oracle GoldenGate for Oracle Database.
- Replicat Compatibility Constraint
-
Replicat compatibility with different trail file formats is ensured using this feature. The Replicat compatibility constraint is associated to the record (LCR) by the primary Extract to restrict certain record to apply by specific version of Replicat in Oracle GoldenGate 21c or higher releases without bumping up the trail file format version. This feature is displayed by the LogDump utility.
- Large DDL (greater than 4 MB) replication is supported
-
DDLs that are greater than 4 MB in size will be provided replication support.
- Certificate management is available from the Microservices Architecture Web UI
-
Server certificates and multiple client certificates can be managed from the Servicer Manager. Each deployment has a Certificate Store that holds the server, client certificates, and CA certificates, which are used when setting up a secure communication channels for a deployment.
- Support for multiple client certificates for wss protocol is available
-
You can store multiple client certificates in the Certificate Store and explicitly specify the type of authentication mechanism for the distribution paths and target-initiated paths as part of the specification.
You can select one of the three authentication mechanisms, Credentials, Client Certificates, or OAuht2.0 (available with Oracle GoldenGate 21.3.0). If you choose the client certificate authentication mechansim, then you can chose a specific client certificate.
- DB_UNIQUE_NAME with heartbeat table
-
DB_UNIQUE_NAME
is available with the heartbeat table to allow users to uniquely identify the source of the heartbeat.DB_UNIQUE_NAME
will allow better use of the heartbeat table in active-active environments, where, typically all the replicas have the sameDB_NAME
but identify each replica site uniquely using theDB_UNIQUE_NAME
.
- DB_UNIQUE_NAME with trail file header
-
DB_UNIQUE_NAME
is added in the trail file header along withDB_NAME
, which helps in troubleshooting replication in active-active environments, where mostly all replicas have the sameDB_NAME
but identify each replica site uniquely using theDB_UNIQUE_NAME
. - Oracle GoldenGate Upgrade Simplification
-
The process to upgrade to Oracle GoldenGate 21c has been further simplified. There are fewer steps necessary for the administrator to upgrade to the latest Oracle GoldenGate release. This includes automatic repositioning of Replicat after a trail file format upgrade.
- Partition Name Filtering
-
The Partition Filtering option filters explicitly on the partition name of tables. Data can be filtered based on source partition names in Extract, Pump, Distribution Service, and Replicat.
- Bounded Recovery Checkpoint Performance
-
The Bounded Recovery (BR) Checkpoint has been enhanced to allow Extract to continue mining the redo log and generate trail files during the BR checkpoint, which decreases the BR intervals and improves Extract restart times.
- Active Data Guard (ADG) Redirection
-
If ADG is configured in a cascaded mode to transport redo logs to a downstream database, Oracle GoldenGate can connect to ADG as a source database for the
REGISTER
command instead of connecting to the database where redo is originated. There is no source database connection needed for registering Extract. - New Replicat parameter INCLUDETAG
-
Oracle GoldenGate for Oracle now supports
INCLUDETAG
in addition to the existingEXCLUDETAG
parameter to allow more flexibility in configuring multi-way replication topologies.
- DB2 z/OS
Default Behavior Changes
This section describes the default behavior changes made to Oracle GoldenGate in relation to the last release.
Release 21c (21.14.0.0.0) - April 2024
- PostgreSQL - Capture and delivery support for base partitioned tables
-
For PostgreSQL, capturing from base partitioned tables is now supported. This is a change from the previous version of Oracle GoldenGate where Extract might have been configured to capture directly against inidividual partitions, such as
TABLE schema.basetable_part1
orTABLE schema.basetable_part2
.If you have configured the Extract to capture from PostgreSQL individual partitions in earlier versions of Oracle GoldenGate and are now upgrading or patching to Oracle GoldenGate 21.14 or after, you need to perform steps specified in Doc ID 3017127.1 to avoid data loss.
Release 21c (21.10.0.0.0) - April 2023
- Oracle Database and MA Deployments
-
- Opatches bundled with JDK for all Oracle and Microservices Architecture deployments
-
The JDK is now packaged in the Oracle GoldenGate patch starting release version 21.10 and 19.1.0.0.230418. Please note that only
<GG_HOME>/jdk
directory is updated with the GoldenGate patch releases. See Doc ID 2359395.1 for more information and additional references for updating JDK either through GoldenGate patch or independently.You still have the option to install the latest JDK patch into
<GG_HOME>/jdk
directory independently at any time. See Doc ID 1492980.1 for more information.
Release 21c (21.4.0.0.0) - October 2021
- SQL Server
-
-
For Oracle GoldenGate Microservices Architecture installations against a source SQL Server database, the Oracle GoldenGate CDC Cleanup job has been replaced with a new Purge Change Data task. A new task is required for Extract to run.
You can create the task from the Administration Service, Configuration, Tasks tab. Create the task after enabling supplemental logging for the tables in a source database and prior to starting the Extract.
-
Oracle GoldenGate Replicat for SQL Server no longer supports OLE DB and Replicat will only use ODBC for its connectivity and to deliver DML operations, and if connecting with the Microsoft ODBC Driver 17 for SQL Server, version 17.8.1 or newer, Replicat will set the connection as the Replication User automatically, which replaces the need to use the
DBOPTIONS
USEREPLICATIONUSER
parameter.
Release 21c (21.3.0) - August 2021
- DB2 for i
-
For DB2 for i, the
ADD HEARTBEATTABLE
command has been enhanced to handle upgrade or misconfiguration of heartbeat table functionality. Now, you can run theADD HEARTBEATTABLE
command again to repair the functionality of an existing heartbeat table setup without deleting the existing heartbeat data.
- SQL Server
-
Extract for SQL Server no longer abends when DDL changes are made to the underlying user tables. In prior releases, if the Extract encountered a mismatch between the user table metadata and the CDC Capture Change Tracking table metadata, due to columns added after TRANDATA was enabled for the table, the Extract would abend. From Oracle GoldenGate 21c (21.3.0) onward, Extract will not abend when table changes are made to the user table. It will continue to process the data as it exists in the CDC Capture Change Tracking table.
This allows the Extract to continue to run when DDL changes occur, but you should use governance to properly handle DDL changes so that Extract can pick up the data for changed columns.
For more information, see the Requirements for Table Level DDL Changes in the SQL Server chapter of the Using Oracle GoldenGate for Heterogeneous Databases guide.
Release 21c (21.1.0) - Initial Release May 2021
- Oracle GoldenGate binaries are no longer installed on a shared drive
-
Oracle always recommended installing the Oracle GoldenGate binaries (
OGG_HOME
) on a local file system as a best practice. From this release onward, it is a requirement. The binaries must be installed on local drives. For more information refer to MOS note DOC ID 2689857.1.
- Simplified heartbeat administration for Oracle Databases
-
Heartbeat table administration operations are only be done in the schema of the
DBLOGIN
user.GGSCHEMA
is now only required for CDB root Extracts.
- Logging of full metadata enabled when upgrading from Oracle GoldenGate 19c to 21c and the database is MySQL 8.0
-
This change is applicable when upgrading from Oracle GoldenGate 19c to 21c with MySQL 8.0.
- Table containing IDENTITY columns with default sequence needs to be created with primary key
-
For Oracle database, table with identity column needs to be created with primary key, otherwise the Replicat will abend with errors similar to the following:
2020-02-07 08:17:53 ERROR OGG-00516 Fatal error executing DDLreplication: error [Error code [1430], ORA-01430: column being added already exists intable]
- One shiphome supporting all Oracle Database versions
-
Instant Client 21c is bundled with Oracle GoldenGate. When launching the Oracle GoldenGate executables with Oracle data layer dependency, it is mandatory to go through the bundled instant client connectivity, libraries, and tools..
- Microservices Architecture does not support the management of individual threads for coordinated Replicat
-
Microservices Architecture does not support the management of individual threads for coordinated Replicat. If you are using individual threads in Classic Architecture and are migrating to MA, you may need to remove those threads before migrations.
