NEW QUESTION # 27
In the CDC mode of a Qlik Replicate task, which option can be set for Batch optimized apply mode?
Answer: C
Explanation:
In Change Data Capture (CDC) mode, Batch optimized apply mode can be set based on time and/or volume.
This means that the batching of transactions can be controlled by specifying time intervals or the volume of data changes to be batched together.
This optimization helps improve performance by reducing the frequency of writes to the target system and handling large volumes of changes efficiently. The Qlik Replicate documentation outlines this option as a method to enhance the efficiency of data replication in CDC mode by batching transactions based on specific criteria.
In the Change Data Capture (CDC) mode of a Qlik Replicate task, when using the Batch optimized apply mode, the system allows for tuning based on time and/or volume. This setting is designed to optimize the application of changes in batches to the target system. Here's how it works:
Time: You can set intervals at which batched changes are applied.This includes setting a minimum amount of time to wait between each application of batch changes, as well as a maximum time to wait before declaring a timeout1.
Volume: The system can be configured to force apply a batch when the processing memory exceeds a certain threshold.This allows for the consolidation of operations on the same row, reducing the number of operations on the target to a single transaction2.
The other options provided do not align with the settings for Batch optimized apply mode in CDC tasks:
A: Source connection processes: This is not a setting related to the batch apply mode.
B: Number of changed records: While the number of changed records might affect the batch size, it is not a setting that can be directly configured in this context.
D: Maximum time to batch transactions: This option is related to the time aspect but does not fully capture the essence of the setting, which includes both time and volume considerations.
Therefore, the verified answer isC. Time and/or volume, as it accurately represents the options that can be set for Batch optimized apply mode in the CDC tasks of Qlik Replicate21.
NEW QUESTION # 28
Which is the command to export the task, task name Oracle_2_SS_Target1 using REPCTL?
Answer: C
Explanation:
To export a task using REPCTL in Qlik Replicate, the correct command isrepctlexportrepository task=task_name. Here's how you would use it for the task named Oracle_2_SS_Target1:
Open the command-line console on the machine where Qlik Replicate is installed.
Use the REPCTL utility with theexportrepositorycommand followed by thetaskparameter and the name of the task you want to export.
The correct syntax for the command is:
repctl exportrepository task=Oracle_2_SS_Target1
This command will create a JSON file containing the exported task settings1.
The other options provided have either incorrect syntax or misspellings:
Ahas a typo in the command (repct1instead ofrepctl).
Buses an incorrect command (export_taskis not a valid REPCTL command).
Dhas a typo in the task name (0racle_2_SS_Target1instead ofOracle_2_SS_Target1) and an incorrect command (exporttaskis not a valid REPCTL command).
Therefore, the verified answer isC, as it correctly specifies the REPCTL command to export the task named Oracle_2_SS_Target11.
NEW QUESTION # 29
Where are the three options in Qlik Replicate used to read the log files located? (Select three.)
Answer: A,E,F
Explanation:
In Qlik Replicate, the options to read the log files are located in the following places:
In Diagnostic package (B): The diagnostic package in Qlik Replicate includes various log files that can be used for troubleshooting and analysis purposes1.
In Data directory of Installation (D): The log files are written to the log directory within the data directory.This is the primary location where Qlik Replicate writes its log files, and it is not possible to change this location2.
In Monitor of Qlik Replicate (E): The Monitor feature of Qlik Replicate allows users to view and manage log files.Users can access the Log Viewer from the Server Logging Levels or File Transfer Service Logging Level sub-tabs1.
The other options provided do not align with the locations where log files can be read in Qlik Replicate:
A: In Windows Event log: This is not a location where Qlik Replicate log files are stored.
C: In External monitoring tool: While external monitoring tools can be used to read log files, they are not a direct feature of Qlik Replicate for reading log files.
F: In Enterprise Manager: The Enterprise Manager is a separate component that may manage and monitor multiple Qlik Replicate instances, but it is not where log files are directly read.
Therefore, the verified answers areB,D, andE, as they represent the locations within Qlik Replicate where log files can be accessed and read21.
NEW QUESTION # 30
When running a task in Qlik Replicate (From Oracle to MS SQL), the following error message appears:
Failed adding supplemental logging for table "Table name" Which must be done to fix this error?
Answer: B
Explanation:
The error message "Failed adding supplemental logging for table" indicates that supplemental logging is not enabled on the Oracle source.
Supplemental logging must be enabled to capture the necessary changes for replication.
To fix this error, you should enable supplemental logging on the Oracle database for the specific table or tables.
This can usually be done by executing the following SQL command on the Oracle source:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
Verify that the logging is enabled and then retry the replication task. This solution aligns with the troubleshooting steps provided in the Qlik Replicate documentation for dealing with supplemental logging errors.
The error message "Failed adding supplemental logging for table 'Table name'" indicates that supplemental logging has not been enabled for the table in the Oracle source database. Supplemental logging is necessary for Qlik Replicate to capture the changes in the Oracle database accurately, especially for Change Data Capture (CDC) operations.
To resolve this error, you should:
Enable supplemental loggingat the database level by executing the following SQL command in the Oracle database:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
This command enables minimal supplemental logging, which is required for Qlik Replicate to function correctly1.
If you need to enable supplemental logging for all columns, you can use the following SQL command:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
This ensures that all necessary column data is logged for replication purposes1.
After enabling supplemental logging, verify that it is active by querying thev$databaseview:
SELECT supplemental_log_data_min FROM v$database;
The correct return value should be 'YES', indicating that supplemental logging is enabled1.
The other options provided are not directly related to the issue of supplemental logging:
A: Contact the Oracle DBA: While contacting the DBA might be helpful, the specific action needed is to enable supplemental logging.
B: Check the permission on the target endpoint: Permissions on the target endpoint are not related to the supplemental logging requirement on the source database.
D: Check the permission of the source endpoint: Permissions on the source endpoint are important, but the error message specifically refers to the need for supplemental logging.
Therefore, the verified answer isC. Enable supplemental logging, as it directly addresses the requirement to fix the error related to supplemental logging in Qlik Replicate21.
NEW QUESTION # 31
Which is the minimum role permission that should be selected for a user that needs to share status on Tasks and Server activity?
Answer: D
Explanation:
To determine the minimum role permission required for a user to share status on Tasks and Server activity in Qlik Replicate, we can refer to the official Qlik Replicate documentation. According to the documentation, there are four predefined roles available: Admin, Designer, Operator, and Viewer. Each role has its own set of permissions.
The Viewer role is the most basic role and provides the user with the ability to view task history, which includes the status on Tasks and Server activity.This role does not allow the user to perform any changes but does allow them to share information regarding the status of tasks and server activity1.
Here is a breakdown of the permissions for the Viewer role:
View task history: Yes
Download a memory report: No
Download a Diagnostics Package: No
View and download log files: No
Perform runtime operations (such as start, stop, or reload targets): No Create and design tasks: No Edit task description in Monitor View: No Delete tasks: No Export tasks: No Import tasks: No Change logging level: No Delete logs: No Manage endpoint connections (add, edit, duplicate, and delete): No Open the Manage Endpoint Connections window and view the following endpoint settings: Name, type, description, and role: Yes Click the Test Connection button in the Manage Endpoint Connections window: No View all of the endpoint settings in the Manage Endpoint Connections window: No Edit the following server settings: Notifications, scheduled jobs, and executed jobs: No Edit the following server settings: Mail server settings, default notification recipients, license registration, global error handling, log management, file transfer service, user permissions, and resource control: No Specify credentials for running operating system level post-commands on Replicate Server: No Given this information, the Viewer role is sufficient for a user who needs to share status on Tasks and Server activity, making it the minimum role permission required for this purpose1.
