Which are valid source endpoint types for Qlik Replicate change processing (CDC)? (Select two )
For Qlik Replicate's Change Data Capture (CDC) process, the valid source endpoint types include:
The other options provided are not typically associated with CDC in Qlik Replicate:
B . MS Dynamics direct access: While Qlik Replicate can connect to various data sources, MS Dynamics is not commonly listed as a direct source for CDC.
D . Generic REST APIs Data Lake file formats: REST APIs and Data Lake file formats are not standard sources for CDC as they do not maintain transaction logs, which are essential for CDC to track changes.
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?
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 logging at the database level by executing the following SQL command in the Oracle database:
ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
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 the v$database view:
SELECT supplemental_log_data_min FROM v$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.
Which files can be exported and imported to Qlik Replicate to allow for remote backup, migration, troubleshooting, and configuration updates of tasks?
In Qlik Replicate, tasks can be exported and imported for various purposes such as remote backup, migration, troubleshooting, and configuration updates. The format used for these operations is the JSON file format. Here's how the process works:
Which is the path to add a new column to a single table in a task?
To add a new column to a single table in a Qlik Replicate task, the correct path is through Table Settings. Here's the process you would typically follow:
Navigate to the Table Settings of the table you wish to modify within your task.
Go to the General section.
Use the option to Add New Column.
This process allows you to add a column directly to the table's schema as part of the task configuration. It's important to note that this action is part of the task's design phase, where you can specify the schema changes that should be applied to the data as it is replicated.
