.NET configuration issue for Pega



An application developer has observed that intermittantly, the PRPC 7.1.7 environment slows down - poor performance is observed by both developers and testing users. 
The application developer has discovered that the performance issue is generally mitigated by performing a shutdown/restart of the PRPC environment.

Error Messages

No error messages are observed on screen.  However, the following error message is observed in the Pega logfile at the beginning of those periods of slowness:

2015-05-04 00:23:46,858 INFO  [STDOUT] (Dispatcher-Thread-24) 2015-05-04 00:23:46,840 [http-] [  STANDARD] [                    ] [        FSA:01.01.01] ( rd.queryexec.SqlQueryExecutor) ERROR hostname| name - An error occured on executing the query for the report definition - There was a problem getting a list: code: 6263 SQLState: S0001 Message: Execution of user code in the .NET Framework is disabled. Enable "clr enabled" configuration option.

Steps to Reproduce

The application developer has observed that when they execute a Report Definition from the Developers Portal, this issue reproduce; any report definition can be executed - not a specific one.

Root Cause

Closer examination of the provided logfile confirmed that the above reported error condition does appear sporadically through the logfile. 
Researching this error condition indicates that the issue is specific to Microsoft SQL Server databases, and is a configuration problem.


To resolve this issue, connect to the Microsoft SQL Server using a SQL Client as the Database administrator, you must issue the following command:

sp_configure 'clr enabled', 1

This resolves the error condition, and the PRPC performance issue is mitigated.
