Two companies are merging Both companies have IBM DB2 LUW running The Qhk Replicate administrator must merge a database (12 TB of data) into an existing database (15 TB of data). The merge will be done by IBM load.
Which approach should the administrator use?
When merging databases, especially of such large sizes (12 TB and 15 TB), it is crucial to ensure data integrity and consistency. The recommended approach is to:
Stop the Replication Task: This is important to prevent any changes from being replicated to the target while the IBM load process is ongoing.
Perform the IBM Load: Execute the IBM load to merge the database into the existing database.
Resume the Replication Task: Once the IBM load has been successfully completed, the replication task can be resumed.
This approach ensures that the data loaded via IBM load is not missed or duplicated in the target database. It also allows Qlik Replicate to continue capturing changes from the point where the task was stopped, thus maintaining the continuity of the replication process.
It's important to note that creating a new task after the IBM load (Option D) could lead to complexities in managing the data consistency and might require additional configuration. Continuing to run the task (Option C) could result in conflicts or data integrity issues during the load process. Therefore, Option B is the safest and most reliable approach to ensure a smooth merge of the databases.
Which components can be controlled with Qlik Enterprise Manager?
Therefore, the correct answer is C. Qlik Replicate, Qlik Compose, Qlik Catalog, as these are the components that can be controlled with Qlik Enterprise Manager.
Which logging level should be used to identify the internal command that Qlik Replicate Is executing prior to an error?
Here's how the Trace logging level works in Qlik Replicate:
Which are the main hardware components to run a Qlik Replicate Task in a high performance level?
To run a Qlik Replicate Task at a high-performance level, the main hardware components that are recommended include:
The other options do not encompass all the recommended hardware components for high-performance levels in Qlik Replicate tasks:
A . SSD, RAM: While these are important, they do not include the network bandwidth component.
B . Cores, RAM: This option omits the SSD, which is important for disk performance.
D . RAM, Network bandwidth: This option leaves out the cores, which are essential for processing power.
A Qlik Replicate administrator will use Parallel load during full load Which three ways does Qlik Replicate offer? (Select three.)
Qlik Replicate offers several methods for parallel load during a full load process to accelerate the replication of large tables by splitting the table into segments and loading these segments in parallel. The three primary ways Qlik Replicate allows parallel loading are:
Use Data Ranges:
This method involves defining segment boundaries based on data ranges within the columns. You can select segment columns and then specify the data ranges to define how the table should be segmented and loaded in parallel.
Use Partitions - Use all partitions - Use main/sub-partitions:
For tables that are already partitioned, you can choose to load all partitions or use main/sub-partitions to parallelize the data load process. This method ensures that the load is divided based on the existing partitions in the source database.
Use Partitions - Specify partitions/sub-partitions:
This method allows you to specify exactly which partitions or sub-partitions to use for the parallel load. This provides greater control over how the data is segmented and loaded, allowing for optimization based on the specific partitioning scheme of the source table.
These methods are designed to enhance the performance and efficiency of the full load process by leveraging the structure of the source data to enable parallel processing
