NEW QUESTION # 16
Invisible columns are columns that are part of a table but not part of the results in a select. When Data Definition Language (DDL) replication is enabled, invisible and virtual columns created in the source environment are replicated in the target environment. What parameter in Extract will exclude invisible columns from replication when using the Integrated Extract?
- A. NOHIDDENCOLUMNS
- B. NOINVISIBLECOLUMNS
- C. EXCLUDEHIDDENCOLUMNS
Answer: C
Explanation:
"Oracle GoldenGate supports replication of invisible columns in Extract.
If you want to exclude them, use the EXCLUDEHIDDENCOLUMNS parameter."
NEW QUESTION # 17
The filter clause provides the ability to include or exclude data to process. What is true with this filter clause: Filter (ON UPDATE, ON DELETE, @Compute(PRODUCT_PRICE * PRODUCT_AMOUNT) > 10000)
- A. Data processing will include rows for delete if (PRODUCT_PRICE * PRODUCT_AMOUNT) is not greater than 10000
- B. Data processing will exclude rows for update if (PRODUCT_PRICE * PRODUCT_AMOUNT) is not greater than 10000
- C. Data processing will exclude rows for delete if (PRODUCT_PRICE * PRODUCT_AMOUNT) is not greater than 10000
- D. Data processing will include rows for insert if (PRODUCT_PRICE * PRODUCT_AMOUNT) is not greater than 10000
Answer: B
Explanation:
The FILTER clause with @Compute and ON UPDATE, ON DELETE includes only those rows where the computed value is greater than 10000. If not, the row is excluded from processing - specifically for UPDATE and DELETE operations.

NEW QUESTION # 19
How can you tell if GoldenGate has been configured for batch processing?
- A. The SPECIALRUN parameter is in the Replicat parameter file
- B. The SPECIALRUN parameter is in the GLOBALS parameter file
- C. The SPECIALRUN parameter is in the Extract parameter file
- D. There is a dedicated GoldenGate process called SPECIALRUN
Answer: A
Explanation:
The SPECIALRUN parameter is used in the Replicat parameter file to configure batch-mode processing such as for initial loads or one-time replication. It disables checkpointing and allows processing of a specific data set without ongoing synchronization.
NEW QUESTION # 20
Where can Oracle GoldenGate software be downloaded officially?
- A. My Oracle Support
- B. OTN or http://edelivery.oracle.com
- C. Oracle Cloud Marketplace
- D. Oracle Database Utilities
Answer: B
NEW QUESTION # 21
What is implemented by Oracle GoldenGate to be able to obtain trail files from the source when the source Distribution Server cannot initiate communication with the target where the Receiver Server is?
- A. The Extract will directly send trail files for the Replicat to receive and apply changes.
- B. A secured port must be implemented and opened by the target to enable the source Distribution Server to be able to initiate communication with the target's Receiver Server.
- C. Microservices Architecture Authentication will initiate communication for the Distribution Server.
- D. A Receiver Server can pull trail files from Distribution Server using a single port for Reverse proxy.
Answer: D
Explanation:
In Oracle GoldenGate Microservices Architecture, when the source Distribution Server cannot initiate outbound communication (e.g., due to firewall or network restrictions), the Receiver Server on the target can be configured to pull trail files using Reverse Proxy mode - establishing a single, secure inbound connection.

- A. Service Manager, Administration Server, Distribution Server, Receiver Server, Performance Metrics Server
- B. AdminClient, Logger, Trail Viewer, Deploy Agent, OGGBridge
- C. Extract, Pump, Replicat, Trail, Checkpoint
- D. Monitor Server, Extract Server, Replicat Server, Admin Console, Trail Manager
Answer: A
Explanation:
These are the key microservices in GoldenGate MA used for deployment, management, data distribution, and monitoring.
NEW QUESTION # 24
What type of multithreaded Oracle GoldenGate Extract uses Oracle's internal log parsing and supports downstream topologies?
- A. Parallel Extract
- B. Integrated Extract
- C. Classic Extract
- D. Coordinated Extract
Answer: B
Explanation:
Integrated Extract is a multithreaded Oracle GoldenGate Extract process that uses Oracle's internal LogMiner server to parse redo logs and supports advanced features like downstream capture, compressed data, and multitenant databases.
NEW QUESTION # 25
Which is an invalid combination for EVENTACTIONS with options?
- A. EVENTACTIONS (CHECKPOINT BEFORE, ABORT)
- B. EVENTACTIONS (CHECKPOINT BOTH, STOP)
- C. EVENTACTIONS (CHECKPOINT BOTH, IGNORE)
- D. EVENTACTIONS (CHECKPOINT AFTER, ABORT)
Answer: C
Explanation:
The combination CHECKPOINT BOTH with IGNORE is invalid because IGNORE tells Replicat to skip the transaction, while CHECKPOINT BOTH implies a complete apply and checkpoint - which contradicts the action of ignoring the transaction.
NEW QUESTION # 26
GGSCI commands can display:
- A. Lag in the system
- B. Processing status
- C. Statistics (operations processed)
- D. All of the above
Answer: D
Explanation:
GGSCI provides status, statistics, and lag details
NEW QUESTION # 27
Prerequisite steps should be followed to ensure a successful Initial Load was performed. One of the steps is to "prepare target tables." What does it mean to prepare target tables?
- A. The target table must exist in the target database before Initial Load process at target site.
- B. The target table must exist in the target database before Initial Load process at source site.
- C. The target database must exist, and an obey file must be used to create all tables for replication before Initial Load process at target site.
- D. The target database must exist, and all tables for replication must exist with data already loaded into tables.
Answer: A
Explanation:
Before performing an Initial Load in Oracle GoldenGate: The structure (tables) must already be created on the target database. GoldenGate does not create target tables during Initial Load - it only copies the data. So, you must manually prepare the tables beforehand.
NEW QUESTION # 28
You must synchronize the starting point for Replicat with the restore point of the target database. How should you accomplish this?
- A. Use the command option UNTIL CANCEL.
- B. Use the command option RESUME.
- C. Use the command option ATCSN.
- D. Use the command option AFTERCSN.
Answer: D
Explanation:
"AFTERCSN causes Replicat to start processing at the transaction that occurred after the one with the specified CSN. Any transactions in the trail that have CSN values that are less than, or equal to, the specified one are skipped."
NEW QUESTION # 29
Which of these is a valid Replicat parameter in Oracle GoldenGate?
- A. DynamicPortList
- B. PASSTHRU
- C. SourceDefs
- D. RmtHost
Answer: C
Explanation:
Replicat with group name, database login parameters; SourceDefs or AssumeTargetDefs, DiscardFile, Map, and others. These can be found in the section titled "Replicat Parameter Categories."
NEW QUESTION # 30
The IF function is used to test one or more conditions and return a value. The Replicat parameter file has the following entry:
- A. Pacific
- B. Central
- C. East
- D. Mountain
Answer: C
Explanation:
The logic in this statement: text Copy Edit @IF(@VALONEOF(STATE, 'CO', 'TX', 'IL'), 'PACIFIC', 'EAST') It checks if the value of STATE is CO, TX, or IL. If true ? returns 'PACIFIC' If false ? returns 'EAST' Since 'CA' is not in that list, the result will be: text Copy Edit TIME ZONE = 'EAST'
NEW QUESTION # 31
Why might you use multiple data pumps for one source trail?
- A. Reduce redo generation
- B. Minimize CPU usage
- C. Encrypt extract data
- D. Send to multiple targets and improve parallelism
Answer: D
Explanation:
To support multiple target systems, table separation, and parallel processing.
