NEW QUESTION # 62
The Integrated Replicat reads the trail, constructs logical change records that represent source DML or DDL transactions, and transmits these records to an inbound server in the Oracle target database. What statement is true about Integrated Replicat?
- A. Trail files contain data that must be in logical change records format.
- B. Integrated Replicat does not need a checkpoint or a trace table for its operations.
- C. Source must be configured as Integrated Extract.
- D. Both source and target can be Oracle and non-Oracle databases.
Answer: A
Explanation:
Integrated Replicat processes Logical Change Records (LCRs). These LCRs are read from trail files and passed to the Inbound Server. It supports parallel apply and uses Oracle Streams APIs internally.
NEW QUESTION # 63
You want to increase parallelism for greater integrated Replicat throughput while preserving the original transaction atomicity. How can you achieve this?
- A. You can configure integrated Replicat with SPECIALRUN parameter.
- B. You can configure integrated Replicat with two parallel apply servers.
- C. You can configure integrated Replicat with two parallel child servers.
- D. You can configure integrated Replicat ASSUMETARGETDEFS and SPECIALRUN parameters.

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. A Receiver Server can pull trail files from Distribution Server using a single port for Reverse proxy.
- B. The Extract will directly send trail files for the Replicat to receive and apply changes.
- C. 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.
- D. Microservices Architecture Authentication will initiate communication for the Distribution Server.
Answer: A
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.

You have an issue where all threads are waiting for a specific transaction to be executed first. What is this issue related to?
- A. It is caused by the use of the MAXTRANSOPS parameter.
- B. It is caused by THREAD and THREADRANGE being used with wildcard MAP statements.
- C. It is caused by barrier transactions in a Coordinated Replicat.
- D. It is caused by the thread with the highest thread ID applying barrier transactions.
Answer: C
Explanation:
In Coordinated Replicat, a barrier transaction is a transaction that must be applied in commit order, causing all threads to pause until that transaction is completed - leading to the situation where all threads wait for one.

NEW QUESTION # 79
In integrated mode, the Replicat process leverages the apply processing functionality that is available within the Oracle database. How does it operate?
- A. It reads the Oracle GoldenGate trail, performs data filtering, mapping, and conversion. Then, it constructs logical change records (LCRs) from source database DML transactions. DDL is applied directly by Replicat. Finally, it transmits the LCRs to the inbound server, which applies the data to the target database.
- B. It reads the Oracle GoldenGate trail, performs data filtering, mapping and conversion. Then, it transmits the regular change records to the inbound server, which applies the data to the target database.
- C. It reads the Oracle GoldenGate trail, performs data filtering, mapping, and conversion. Then, it constructs logical change records (LCRs) from source database DML transactions. Then it is attached to a background process in the target database by means of lightweight streaming mechanism, which transmits the LCRs to the inbound server, which applies the data to the target database.
- D. It reads the Oracle GoldenGate trail, performs data filtering, mapping and conversion. Then, it constructs logical change records from source database DML transactions. Next, it uses standard SQL to apply data directly to the target tables.
Answer: A
Explanation:
Integrated Replicat constructs LCRs for DML, sends them to the inbound server for apply, while DDL is applied directly by Replicat-not through the inbound server.
