Which file should you edit to enable SSL for a JobServer?
To enable SSL for a JobServer, you need to edit the conf/TalendJobServer.properties file. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. The conf/TalendJobServer.properties file contains various configuration parameters for your JobServer, such as port number, log level, security options, etc. To enable SSL for your JobServer, you need to set the ssl parameter to true and provide the path and password of your keystore file that contains your SSL certificate.
You do not need to edit conf/TalendServer.properties, conf/server.xml, or jsl_static64.ini files. These files are not related to JobServer configuration or SSL settings. The conf/TalendServer.properties file is used to configure Talend Administration Center settings, such as database connection, LDAP authentication, email notification, etc. The conf/server.xml file is used to configure Tomcat server settings, such as connectors, realms, valves, etc. The jsl_static64.ini file is used to configure Java Service Launcher settings, such as service name, description, startup type, etc. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Configuring Talend JobServer - 7.3], [Configuring Talend Administration Center - 7.3], [Configuring Tomcat - 7.3], [Installing Java Service Launcher - 7.3]
Where can you specify the remote JobServer to execute a Job?
To specify the remote JobServer to execute a job, you need to use the Target Exec tab in the Run view of Talend Studio. The Run view allows you to configure and execute your job from Talend Studio. The Target Exec tab allows you to select whether you want to run your job locally or remotely on a JobServer. A JobServer is a server application that allows you to execute jobs remotely from Talend Studio or Talend Administration Center. To run your job on a remote JobServer, you need to select Remote Jobserver option from the drop-down menu and select or add a JobServer connection from the list.
You do not need to use Job settings section of Project Settings window, Extra tab in Job view, or Run/Debug section in Preferences window. These windows are not used to specify remote JobServer execution. The Job settings section of Project Settings window is used to configure general settings for your jobs, such as versioning, statistics, logs, etc. The Extra tab in Job view is used to configure extra features for your job, such as implicit context load, tStatCatcher, tLogCatcher, etc. The Run/Debug section in Preferences window is used to configure run/debug settings for your Talend Studio, such as JVM arguments, execution mode, etc. Reference: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Run view - 7.3], [Project Settings - 7.3], [Job view - 7.3], [Preferences - 7.3]
Which actions can you perform in the configuration panel in Pipeline Designer? Choose 2 answers.
Comprehensive and Detailed Explanation:
In Talend Pipeline Designer, the configuration panel provides options for managing and modifying the settings of components within a pipeline.
Modify processor values (Option A):
Users can adjust values for processors such as filters, joins, transformations, and aggregations within the configuration panel.
This helps fine-tune data processing rules directly in the pipeline.
Display and update dataset connections (Option B):
The configuration panel allows users to change dataset connections, updating the source or target locations of data.
Users can modify database credentials, file paths, or API endpoints as needed.
Why not other options?
Option C: The ability to preview changes made by processors is handled in the preview panel, not the configuration panel.
Option D: Pipeline export settings are managed separately in the export settings menu, not in the configuration panel.
You create a Job consisting of two subJobs, A and B. You added Joblet C with the intension of running it between A and B.
What are the minimum requirements to orchestrate this? (Choose Two)
To create a job consisting of two subjobs, A and B, and add a Joblet C with the intention of running it between A and B, you need to do the following steps:
Design subjob A by adding components and links to it in the Designer workspace.
Add a Start component to mark the beginning of subjob B and link it to subjob A using an OnSubjobOk trigger.
Design subjob B by adding components and links to it after the Start component in the Designer workspace.
Add a tJobletTriggerInput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
Add a tJobletTriggerOutput component to your Joblet C design and link it to other components in your Joblet using data flows or triggers.
Drag your Joblet C from the Repository tree view to the Designer workspace between subjob A and subjob B.
Link your Joblet C to subjob A using an OnComponentOk trigger from the last component of subjob A to the tJobletTriggerInput component of your Joblet C.
Link your Joblet C to subjob B using an OnComponentOk trigger from the tJobletTriggerOutput component of your Joblet C to the Start component of subjob B.
The minimum requirements to orchestrate this are adding TRIGGER_INPUT and TRIGGER_OUTPUT components into C and linking A, B, and C using OnSubjobOk triggers. These are generic components that allow you to define triggers for your Joblet without depending on specific components. You do not need to add TRIGGER_INPUT and TRIGGER_OUTPUT components into A or B, as these are regular subjobs that can use any type of components or triggers.

You are building a complex Job and want to explore different options for optimizing execution times using parallelism.
How can you identify execution times to verify the effectiveness of your changes?
Choose 2 answers
To identify execution times to verify the effectiveness of your changes, you can use one of these methods:
Reading the time stamps from the execution console in the Run view. This method allows you to see the start and end time of each subjob and component in your job, as well as the total execution time of the job. You can also see the number of rows processed by each component and the status of the job (success or failure).
Observing the execution times that annotate the flows in the Designer. This method allows you to see the execution time of each flow (main, lookup, reject, etc.) between components in your job. You can also see the number of rows processed by each flow and the throughput (rows per second) of each flow.
You cannot use these methods to identify execution times:
Observing the execution time in the Code view. This method does not show you the execution time of your job or its components, but only the generated code of your job in Java or Perl. The Code view is useful for debugging or customizing your code, but not for measuring performance.
Comparing time stamps in Trace Debug mode. This method does not show you the execution time of your job or its components, but only the values of each column for each row processed by your job. The Trace Debug mode is useful for tracing data quality or transformation issues, but not for measuring performance.
