Conflicts occur when the timing of simultaneous changes results in one of out-of-sync conditions: a replicated insert attempts to add a row that already exists in the target. the before image of a replicated update does not match the current row in the targ a replicated delete attempts to remove a row that does not exist in the target.

Performance - Streaming

Prior to Oracle GoldenGate 11gR2 Synchronous data communication between data pump

extract and remote collector process

Data sent by data pump extract to remote collectorprocess must be followed with ACK from the remotecollector. Extract can only send out new data after ACK.

Oracle GoldenGate 11gR2 Acknowledgement message can be skipped for every

data sent Remote collector does not send an acknowledgement

to the data pump extract unless a packet contains aflag requesting a response, typically when the datapump extract must checkpoint or determine a writeposition .

Inbound Server (Database Apply Process)

Receiver : Reads LCRs

Preparer : Computes the dependencies between the transactions (primary key, uindexes, foreign key) , grouping transactions and sorting in dependency order.

Coordinator : Coordinates transactions, maintains the order between applier pr

Applier : Performs changes for assigned transactions, including conflict detectierror handling.

Integrated Replicat - Dependency Aware Apply Source Database Supplemental Logging

Supplemental logging of scheduling columns (PK, UI, FK) needed for dependency awareapply processing at targetNew default of ADD TRANDATA is to log all unique indexes and foreign key columns .

If Primary Key, Unique Index, Foreign Key columns are same at both source andtarget, ADD TRANDATA provides requisite information. If target has differentscheduling columns, then ADD TRANDATA [table] COLS format should beused to identify any additional columns

For old behavior specify NOSCHEDULINGCOLS option to only log primary key

ADD TRANDATA [table], NOSCHEDULINGCOLS

ADD SCHEMATRANDATA [schema], NOSCHEDULINGCOLS Scheduling columns must be present in trail file

Extract parameter LOGALLSUPCOLSIncludes any supplementally logged column in trail file

Automatically enables GETUPDATEBEFORES and NOCOMPRESSDELETES

DDL (Oracle only) Primary Key Update EMI SQLEXEC

Ease of Use Simplify parameter file manageability (fewer param files) Simplify error recovery

Key ConceptsCoordinated vs. Integrated Replicat

Coordinated Replicat Integrated Replicat

User Specified Partitioning Automatic Scheduling

Split transaction Semantics Does not split transactions

All databases Oracle specific with version requirements

Continues to employ SQL generation andexecution outside the database.

Apply is in the database server. Tightintegration with Oracle database.

Integrated Extract

Integrated Extract was introduced in Oracle GoldenGate 11.2

Oracle GoldenGate 12.1.2 enhances the feature. With Oracle GoldenGate 12.1.2

By default, all newly created extracts will be integrated extract Upgrading from old IE you can use TRANLOGOPTION _LCRCAPTUREPRO

V2 _LCRCAPTUREPROTOCOL V2 provides better performance by

Streamlined for improved performance (V2 as fast or faster than Classic Extr Drastic improvement in LOB performance Reduced overhead on database Available when the mining server is 11.2.0.3 BP 14 and higher or Oracle 12c

Overview


26/30


Integrated Extract

Requirements: Database must be running Oracle Database 12c (12.1.0.1), 11.2.0.4 and later versions. DDL Trigger Removal is required for CDB.

Behavior Integrated Extract running against Oracle Database 12c or 11.2.0.4 will automatically run in

mode No need to run DDL setup scripts DDL trigger can remain enabled

Integrated Extract running against Oracle Database 11g Release 11.2.0.3 will get metadatagathered from DDL trigger

Classic Extract will continue to require existence of DDL trigger

DDL Trigger Removal

Integrated Extract and Replicat Review

Integrated Extract Oracle GoldenGate 12.1.2: the source database can be 11.1 or 11.2 or above. ... the MININ

database has to be version newer than the source database, but must be 11.2.0.3 BP 6 or hiSame as OGG 11.2.1.

If the source database is Oracle DB 12.1, then OGG 12.1.2 must be used. For Oracle Database 12c with CDB setup, integrated extract is required.

Integrated Replicat Target database has to be Oracle Database 12.1.0.1 and 11.2.0.4. The source database (Extract) can be other databases but have to include required supplem

logging information for dependency calculation. Oracle GoldenGate 11.1.1 and 11.2.1 versions or non Oracle source databases, use 2

parameters: GETUPDATEBEFORES and NOCOMPRESSDELETES, these are require For Oracle GoldenGate 12.1.2 use LOGALLSUPCOLS and UPDATERECORDFO

This works for classic and integrated extract only.
