Define function input parameters on the Create or Save As forms
Valid from Pega Version 7.1.8
When creating or updating a Rule-Utility-Function ruleset in Designer Studio, use the Create or Save As forms to define or change parameters as a part of the form. The Parameters section on either of these forms allows you to set the function's name and Java type before opening the function.
Previously, you updated these fields on the Parameters tab for the function after the form was created. Moving these fields to the Create and Save As forms helps to proactively detect functions with the same signature in the same ruleset before saving the function.
For more information, see Defining function input parameters on the Create or Save As forms.
Convert data instances into decision parameter rules
Valid from Pega Version 7.1.8
The Convert groups wizard is available in the Hierarchy landing page when the list of your propositions include decision data records.
Click Convert groups at the top of the landing page to use the wizard and to convert data instances into decision parameter rules. This conversion is necessary to make the existing proposition data instances available for revision management.
Data Flow transformation shapes cannot be used in combination with the Compose or Merge shapes
Valid from Pega Version 7.1.8
When you reference another data flow from a data flow that contains the Compose or shape, the referenced data flow cannot contain transformation shapes ( , , ).
Data flow validation does not currently prevent you from designing a data flow that goes against this design pattern. Make sure that your data flows follow this design pattern by checking the referenced and referencing data flows.
Ability to periodically defragment the PR_SYS_LOCKS table
Valid from Pega Version 7.1.8
Lock management in Pega 7 is controlled through the database table PR_SYS_LOCKS. Because of the high volume of entries inserted into and deleted from this table during case processing, the data in the PR_SYS_LOCKS table can become highly fragmented, causing degraded performance over time.
You can now periodically defragment this table. The following Dynamic System Settings control when and how often defragmentation takes place using DefragSysLocksDaemon:
syslocks/defragIntervalType
Custom interval type to run defragmentation
Set this first – determines whether defragmentation occurs daily at a specified hour or at a recurring interval
- syslocks/defragHourOfDay
- Used to run defragmentation at a specified hour
- Accepts only integer values in the range 0-23
- Example: run defragmentation daily at 1 AM by entering a value of "1"
Can be ignored if syslocks/defragIntervalType indicates a a specified periodic interval
- syslocks/defragIntervalInHours
- Used to run defragmentation at specified periodic intervals
- Accepts only integer values > 0
Example: run defragmentation every four hours by entering a value of "4"
Can be ignored if syslocks/defragIntervalType indicates a specified hour
