The goal is to convert a timestamp to Unix time (seconds since January 1, 1970).

The strftime function is used to format date and time values.

To get the Unix epoch time, you can use the command: strftime('%s',SAR_H_COMMIT_TIMESTAMP) - strftime('%s','1970-01-01 00:00:00').

This command extracts the Unix time from the timestamp and subtracts the Unix epoch start time to get the number of seconds since January 1, 1970. This is consistent with the Qlik Replicate documentation and SQL standard functions for handling date and time conversions.

To convert a timestamp to Unix time (also known as Unix epoch time), which is the number of seconds since January 1st, 1970, you can use the strftime function with the %s format specifier in Qlik Replicate. The correct syntax for this conversion is:

strftime('%s', SAR_H_COMMIT_TIMESTAMP) - strftime('%s','1970-01-01 00:00:00')

This function will return the number of seconds between the SAR_H_COMMIT_TIMESTAMP and the Unix epoch start date. Here's a breakdown of the function:

strftime('%s', SAR_H_COMMIT_TIMESTAMP) converts the SAR_H_COMMIT_TIMESTAMP to Unix time.

strftime('%s','1970-01-01 00:00:00') gives the Unix time for the epoch start date, which is 0.

Subtracting the second part from the first part is not necessary in this case because the Unix epoch time is defined as the time since 1970-01-01 00:00:00. However, if the timestamp is in a different time zone or format, adjustments may be needed.

The other options provided do not correctly represent the conversion to Unix time:

Options A and B use datetime instead of strftime, which is not the correct function for this operation1.

Option C incorrectly includes <code>datetime.datetime</code>, which is not a valid function in Qlik Replicate and seems to be a mix of Python code and SQL1.

Option E uses Time.now.strftime, which appears to be Ruby code and is not applicable in the context of Qlik Replicate1.

Therefore, the verified answer is D, as it correctly uses the strftime function to convert a timestamp to Unix time in Qlik Replicate1.

To add a new source endpoint in Qlik Replicate, in addition to the connection string, username/password, and permission to the database, the presence of transactional logs is essential. Transactional logs are crucial because they record all changes made to the database, which Qlik Replicate uses to capture the data changes that need to be replicated.

Here's the process of adding a new source endpoint:

Access to the system: You must have access to the system where the endpoint resides.

Connection information: Provide the connection string, which includes the network address and other parameters needed to connect to the source database.

User credentials: Supply the username and password that have the necessary permissions to access the database.

Transactional logs: Ensure that transactional logs are available and accessible because Qlik Replicate uses these logs to track changes in the source database for replication purposes.

The requirement for transactional logs is consistent with the nature of Qlik Replicate's operation, which relies on change data capture (CDC) technology to detect and replicate database changes12.

It's important to note that while the database client (option A) and access to the database server (option D) are also important components in the overall setup, they are not specifically required to add a new source endpoint in the context of this question. File access (option B) is not directly related to the addition of a source endpoint in Qlik Replicate.

To change the Data Directory location on Windows for Qlik Replicate, the administrator needs to follow these steps after stopping the Qlik Replicate services:

E . Move the data directory to a new location: The first step is to physically move the data directory to the new desired location on the file system1.

A . Update the Windows Registry: After moving the data directory, the next step is to update the Windows Registry to reflect the new location of the data directory. This involves modifying the ImagePath string within the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services for both the Qlik Replicate UI Server and Qlik Replicate Server services1.

F . Start the Attunity Replicate services: Once the data directory has been moved and the Windows Registry has been updated, the final step is to start the Qlik Replicate services again. This will allow Qlik Replicate to operate using the new data directory location1.

The other options are not part of the recommended steps for changing the Data Directory location:

B . Uninstall Qlik Replicate and reinstall: This is not necessary just for changing the data directory location.

C . Copy the data directory to a shared drive and keep all tasks running: It is not recommended to use a shared drive for the data directory, and tasks cannot run during this process since the services need to be stopped.

D . Stop the Attunity Replicate Ul Server and Attunity Replicate Server services: This is a prerequisite step that should have already been completed before proceeding with the data directory change.

For a complete guide on changing the Data Directory location on Windows, the official Qlik documentation provides detailed instructions and considerations1.

When loading data into a Cloud Storage Data Warehouse like Snowflake, Synapse, Redshift, or Big Query, the type of storage required for the COPY statement is Object Storage such as Azure Data Lake Storage (ADLS), Amazon S3, or Google Cloud Storage (GCS). This is because these cloud data warehouses are designed to directly interact with object storage services, which are scalable, secure, and optimized for large amounts of data.

For example, when using Microsoft Azure Synapse Analytics as a target endpoint in Qlik Replicate, the COPY statement load method requires the Synapse identity to be granted ''Storage Blob Data Contributor'' permission on the storage account, which is applicable when using either Blob storage or ADLS Gen2 storage1. Similarly, for Amazon S3, the Cloud Storage connector in Qlik Application Automation supports operations with files stored in S3 buckets2. The prerequisites for using Azure Data Lake Storage (ADLS) Gen2 file system or Blob storage location also indicate the necessity of these being accessible from the Qlik Replicate machine3.

Therefore, the correct answer is D. Object Storage (ADLS, S3, GCS), as these services provide the necessary infrastructure for the COPY statement to load data efficiently into cloud-based data warehouses.

In Qlik Replicate, notifications can be set up for various events related to tasks, endpoints, and the server itself. The types of notifications that can be configured include:

Task Events: Notifications for task-based events, such as when a task starts or stops, when latency is too high, or when specific errors occur1.

Endpoint Events: While the search results did not explicitly mention ''Endpoint Events,'' it is common in replication tools to have notifications related to endpoints, such as connectivity issues or endpoint-specific errors.

Server Events: Notifications related to the server, which could include system state changes, performance issues, or server-level errors2.

Therefore, the correct answer is C. Server Events, Endpoint Events, and Task Events, as Qlik Replicate allows setting up notifications for all these types of events. This ensures that administrators are alerted to a wide range of potential issues, allowing for prompt response and resolution.

For detailed instructions on how to set up each type of notification in Qlik Replicate, you can refer to the official Qlik documentation, which provides step-by-step guidance on defining and managing notifications for task events, server events, and other significant occurrences within the replication environment132.
