- APIs
  Application programming interfaces (APIs) provide functions that simplify applications development.
- Job configuration overlays
  You can specify or change configuration parameters when you use the submitjob or updateoperators operations. The settings control submission constraints, host constraints and locations, and operator status. Parameters are captured and updated in the configuration JSON file. When you change the values in the job configuration overlay file, the changes override any previously set values.
- Commands
  Teracloud® Streams provides a number of commands you use to perform tasks.
- Operator model
  An operator model is an XML document that describes the basic properties of a primitive operator.
- Streams Processing Language (SPL)
  Streams Processing Language (SPL) is a distributed data flow composition language that is used in Teracloud® Streams. SPL has primitive types, program structures, and definitions that are tailored for streaming data.
- Toolkits
  A toolkit is a set of SPL artifacts, which are organized into a package. Toolkits make SPL or native functions and primitive or composite operators reusable across different applications.
  - Specialized toolkit requirements and restrictions
    Several of the specialized toolkits require RPMs that are not required by the Teracloud® Streams product. There are also toolkit restrictions on some platforms.
  - Toolkits
- SPLDOC markup
  You can use SPLDOC markup in the descriptions associated with the SPL artifacts in a toolkit. The spl-make-doc command generates HTML documentation from the marked up artifacts.

Configure your Lookup Manager with Application Configuration

The Application Configuration is an Streams platform function that allows you to store configuration parameter of your application in the Streams console. Your application can read them at run time and it can update the values that are specified at compile time or submission time.

Before you begin

As the lookup repository uses a database as the data source, this use case requires an installed and configured database. The streams domain must run and you must be authorized to manage the streams domain and the streams instance.

About this task

Configure the Lookup Manager application to use a database by using the Application Configuration.

Procedure

In the file <PathToYourApplication>/config/config.cfg, find the lm.applicationConfiguration parameter.
To specify the Application Configuration name, set the parameter to the wanted value, for example: lm.applicationConfiguration=MyApplConfig.
Open a linux shell terminal.
To get the valid link to streams console, call following command: streamtool geturl.
Copy the link.
Open a browser and paste the link to the address line to open the streams console.
Log in to console by using the credentials. The console opens the dashboard view.
Open the Streams console as described in Creating application configuration objects to connect Streams to your device management service chapter and enter the properties to the table:

a. Complete the same Application Configuration name in the Name as you defined for the lm.applicationConfiguration parameter, for example: MyApplConfig.

b. To specify the data source name (DSN) of the target database, set the parameter name as the propertyName: lm.db.name.

c. To specify the value of the data source name (DSN) of the target database, set the wanted value as the propertyValue, for example: DBName.

e. To specify the database user, set the parameter name as the propertyName: lm.db.user.

f. To specify the value of the database user, set the wanted value as the propertyValue, for example: dbUser.

h. To specify the database user password, set the parameter name as the propertyName: lm.db.password.

i. To specify the value of the database user password, set the wanted value as the propertyValue, for example: dbUserPassword
Finalize the creation of the application configuration object.
