CERN IT Department CH-1211 Geneva 23 Switzerland t GoldenGate Overview Introduction to GoldenGate administration 3 Installation GG home to be installed + additional steps for deployment under RAC Configuration Configuration of each component though parameter files and GG Command Line Interface (GGSCI)

CERN IT Department CH-1211 Geneva 23 Switzerland t GoldenGate Architecture Introduction to GoldenGate administration 4 Commited changes are captured as they occur by reading the transaction logs Trail files: Stages and queues data for routing Applies data with transaction integrity, transforming the data as required Distribute data for routing to multiple targets

CERN IT Department CH-1211 Geneva 23 Switzerland t Parameter File: Manager Introduction to GoldenGate administration 5 PORT: Port for communication between itself and other local Oracle GoldenGate process LAGREPORTMINUTES: To specify the interval at which manager checks for extract and replicat lag PURGEOLDEXTRACTS: To control the purging of files from the local trail USECHECKPOINTS: Triggers a purge when all processes are finished with a file as indicated by their checkpoints MINKEEPDAYS: To set a minimum amount of time to keep data. With USECHECKPOINTS, if checkpoints indicate that a file has been processed completely, it will be purged unless doing so would violate the MINKEEP rules

CERN IT Department CH-1211 Geneva 23 Switzerland t Parameter File: EXTRACT Introduction to GoldenGate administration 6 EXTTRAIL: To specify the path name of the trails LOGALLSUPCOLS: To control the writing of supplementally logged columns TRANLOGOPTIONS: To control the way that Extract interacts with the transaction log or with the API that passes transaction data max_sga_size: Controls the amount of shared memory used by the logmining server parallelism: Controls the number of processes used by the logmining server DDLOPTIONS: To configure aspects of DDL processing TABLE: It is limited to table-to-table mapping

CERN IT Department CH-1211 Geneva 23 Switzerland t Parameter File: Data Pump Introduction to GoldenGate administration 7 INCLUDE: For using a macro library RMTHOST: Identify a remote system to which the local Extract process connects RMTTRAIL: To specify the location of the remote trail DISCARDFILE: To specify the discardfile where are rejected records will be dumped PASSTHRU: Mode being used for the DP where the name of source and target objects are identical and no column mapping or filtering is being performed TABLE: It is limited to table-to-table mapping

CERN IT Department CH-1211 Geneva 23 Switzerland t Parameter File: Replicat Introduction to GoldenGate administration 8 ASSUMETARGETDEFS: To indicate that the source and target tables are identical, including semantics. DISCARDFILE: To specify the discardfile where are rejected records will be dumped DBOPTIONS INTEGRATEDPARAMS: To specify database options passing settings for parameters that control the database inbound server within the target DDL INCLUDE ALL: Required if replicating DDL operations MAP: To specify the mapping to be replicated between source and target database
