Question No: 12

The application developer wants to use raw data reports to obtain usage information about the applications and adapters.

To enable raw data reports feature, the application developer needs to:

  1. set reports.exportRawData property to true and configure the wl.reports.db properties to the databasesettings in the worklight.properties file.

  2. set reports.exportRawData property to true and configure the wl.reports.db properties to the databasesettings in the application-descriptor.xml file.

  3. stop Worklight Server, set reports.exportRawData property to true and configure the wl.reports.dbproperties to the database settings in the worklight.properties file, then restart Worklight Server.

  4. stop Worklight Server, set reports.exportRawData property to true and configure the wl.reports.dbproperties to the database settings in the application-descriptor.xml file, then restart Worklight Server.

Answer: C Explanation:

Raw data reports provide you with analytics information about your applications and adapter usage, such as activity type, device information, and application version. Use the following steps to enable the raw data reports feature:

Procedure

-> Ensure that the IBM Worklight Server application server is not running.

-> Create a separate database or a new schema for reports.

-> When you work in a development environment, complete the following steps.

3a. Edit the worklight.properties file. Uncomment the reports.exportRawData property and set its value to true. 3b. Modify the wl.reports.db properties to contain your database settings as shown in the following example.

#################################################

# Raw reports

################################################# reports.exportRawData=true

# jndi name; empty value means Apache DBCP data source

#wl.reports.db.jndi.name=${wl.db.jndi.name}

# Default values for DBCP connection pool

#wl.reports.db.initialSize=${wl.db.initialSize}

#wl.reports.db.maxActive=${wl.db.maxActive}

#wl.reports.db.maxIdle=${wl.db.maxIdle}

#wl.reports.db.testOnBorrow=${wl.db.testOnBorrow} wl.reports.db.url=jdbc:mysql://localhost:3306/wlreport wl.reports.db.username=worklight wl.reports.db.password=worklight

Ensure that the wl.reports.db.url property contains the URL of the database you are planning to use for raw data.

4 When you work in a production environment, connect to the reports database by using JNDI environment entries in addition to editing the worklight.properties file, as described in the previous step.

  1. Restart your application server. References:

Question No: 19

An application developer has created a hybrid application and is in the process of adding a platform-specific environment for iPhone.

When the application developer adds the new environment for iPhone, what folders will automatically be created under the /apps/{Application_name}/iphone folder once the platform environment has been built?

  1. css, html, js, native, nativeResources

  2. css, html, legal, native, nativeResources

  3. css, images, js, native, nativeResources

  4. css, images, legal, native, nativeResources

Answer: C Explanation:

The app code can include CSS files to define the application view. Style sheets are placed under the \common folder (normally under \common\css) and optionally in the optimization and skin folders.

Worklight Studio creates a default thumbnail image when the app is created. You can override this default image (using the same file name) with a replacement image that

matches your application. The file is in the \common\images folder of the app.

The app code can include JavaScript files that implement interactive user interface components, business logic and back-end query integration, and a message dictionary for globalization purposes. Scripts are placed under the \common folder (normally under

\common\js) and optionally in the optimization and skin folders.

For Apple iOS platforms, the default splash images are stored as follows:

For iPhone, under iphone\native\Resources For iPad, under ipad\native\Resources References: https://www.ibm.com/support/knowledgecenter/SSZH4A_6.1.0/com.ibm.worklight.dev.doc/ devref/ r_application_resources.html
