You need to read data from three oracle tables that store sales data from three regions to load into a single oracle table. These three tables are having the same table definitions and the only difference is that each table contains data for a particular region. Which of the following will do the required task?

technology platforms and products

  1. Create a task with single oracle enterprise stage that executes a custom SQL statement with FETCH ALL, that outputs to an Oracle enterprise stage.

  2. Create a job with three Oracle Enterprise stages to read from the tables and output to a collector stage which in turn outputs the data to an Oracle Enterprise stage.

  3. Create a job with a single Oracle Enterprise stage that executes a custom SQL statement with UNION ALL that outputs the data to an oracle enterprise stage.

  4. Create a job with three Oracle Enterprise stages to read from the tables and output to a Funnel stage which in turn outputs the data to an oracle enterprise stage.

Show answer
Correct Option: C,D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Create a task with a single Oracle Enterprise stage that executes a custom SQL statement with FETCH ALL, that outputs to an Oracle Enterprise stage.

This option is incorrect because using FETCH ALL in a custom SQL statement will only fetch all rows from a single table, not from multiple tables.

Option B) Create a job with three Oracle Enterprise stages to read from the tables and output to a collector stage which in turn outputs the data to an Oracle Enterprise stage.

This option is incorrect because using a collector stage will not combine the data from the three tables into a single table. It will only collect the data from each table separately.

Option C) Create a job with a single Oracle Enterprise stage that executes a custom SQL statement with UNION ALL that outputs the data to an Oracle Enterprise stage.

This option is correct because using UNION ALL in a custom SQL statement will combine the data from the three tables into a single result set. The Oracle Enterprise stage can then output this combined data to a single table.

Option D) Create a job with three Oracle Enterprise stages to read from the tables and output to a Funnel stage which in turn outputs the data to an Oracle Enterprise stage.

This option is correct because using a Funnel stage will combine the data from the three Oracle Enterprise stages into a single stream. The combined data can then be output to an Oracle Enterprise stage to load into a single table.

The correct answer is C, D. These options will allow you to read data from the three Oracle tables and load it into a single Oracle table. Option C uses UNION ALL in a custom SQL statement, while Option D uses a Funnel stage to combine the data.

The uv command in a UNIX datastage server is used to --------?

technology platforms and products

  1. Cleanup resources from a failed datastage job

  2. Start and stop datastage engine.

  3. Provide read access to Datastage configuration file.

  4. Report datastage client connections.

Show answer
Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Cleanup resources from a failed Datastage job - This option is incorrect. The "uv" command in a UNIX Datastage server is not used specifically to clean up resources from a failed Datastage job. There are other commands and processes in Datastage that handle job cleanup.

Option B) Start and stop Datastage engine - This option is correct. The "uv" command in a UNIX Datastage server is used to start and stop the Datastage engine. It is used to control the Datastage server and manage the execution of Datastage jobs.

Option C) Provide read access to Datastage configuration file - This option is incorrect. The "uv" command is not used to provide read access to the Datastage configuration file. Access to the configuration file is typically managed through file permissions and other access control mechanisms.

Option D) Report Datastage client connections - This option is incorrect. The "uv" command does not specifically report Datastage client connections. There are other commands and tools that can be used to monitor and report on Datastage client connections.

The correct answer is B) Start and stop Datastage engine. This option is correct because the "uv" command in a UNIX Datastage server is used to start and stop the Datastage engine, allowing for the control and management of Datastage jobs.
