New Cache Dialog Box Properties

This topic describes how you can use the New Cache dialog box to create a schedule task to generate cached report data for the specified data resources.

Server displays the dialog box when an administrator selects New Cache in the Administration > Configuration > Cache > Data Cache page on the Server Console.

The dialog box includes two phases, one for selecting data resources and the other for defining the schedule task.

Selecting Data Resources Phase

At this phase, you need to specify the data resources for which you want to create cached data.

Select a Folder

Specify the folder in the server resource tree that contains the required catalog. You can select the ellipsis button to open the Select Folder dialog box for selecting the folder.

Select a Catalog

Select a catalog in the folder.

Select Queries

Server lists the selected data resources.

• Add button
  Select to open the Select Queries dialog box to select the data resources that you want to create data caches for.
• Remove button
  Select to remove the selected data resources.

OK

Select to go to the next phase to define the schedule information.

Cancel

Select to close the dialog box without creating a data cache.

Help

Select to view information about the dialog box.

Defining the Schedule Task Phase

At this phase, you need to define the data resource information and the updating policy of the data cache on these tabs:

• General
• Conditions
• Notification

Back

Select to go back to the previous tab.

Next

Select to go to the next tab.

Finish

Select to create the data cache.

Cancel

Select to return to the selecting data resources phase without saving any changes.

Help

Select to view information about the dialog box.

General

Before scheduling a CRD task, you need to configure the settings in this tab first.

Select Query

Server lists all the query resources you selected in the Selecting Data Resources Phase. Select a query resource from the list, and then specify the general properties of its scheduled CRD task.

Enter Parameters

Specify the values of the parameters you want to apply to the selected query resource. You may specify parameter values in these ways.

If the query resource does not have parameters, Server displays "No Parameter Needed" here.

Cached Report Data Info

Specify the data cache information.

• Name
  Name of the selected query resource. Server also uses it as the name of the new data cache.
• Data Source
  Data source in which the query resource is.
• Catalog
  Path of the catalog in which the query resource is. Server uses the latest catalog version by default.
• Type
  Type of the query resource.
• Priority
  Specify the priority level of the scheduled task. The priority levels are from 1 to 10 in ascending order of lowest priority to highest priority. By default, Server ignores this property unless you modify server.properties in <install_root>\bin to set queue.policy not equal to 0.

Advanced

Configure some advanced settings.

• Connect to [Data Source Name]
  Specify the DB user and password for connecting to the data source.
  • Use the DB user and password defined in catalog
    Select if you want to use the DB user and password defined in the catalog.

    Select this property, and you can then specify another DB user and password instead of the one defined in the catalog.
• Add TaskListener to be Invoked
  Select to call a Java application before/after the task runs to obtain information about the task.
  
• Enable Auto Recover Task
  Select if you want Server to automatically recover the task.
  • Maximum Retry Times
    Specify the maximum number of times for retrying running the task to recover it.
  • Retry Interval
    Specify the interval between retries.
  • Recreate All Results
    Select if you want to recreate all results. By default, Server only recreates failed results.

Conditions

Use the Conditions tab to specify the updating policy of the task. The tab contains two more tabs:

• Time
• Trigger

Time

Use the Time tab to specify the time for when you want to perform the task.

    • Run after
      Select and then specify the start date and time of the period.

  When you select this logic:

  • No matter which condition is ready, Server performs the task only when its counterpart is ready.

• Time Condition after Trigger
  Select if you want to perform the task when time is up after an administrator fires the trigger. If the time condition is ready before the trigger condition, Server regards the task as expired and deletes it.
• Time Condition or Trigger
  Select if you want to perform the task when either time is up or an administrator fires the trigger.
