  I would expect to see the following log line in the Policy Server

  12.52SP1CR04 log, but I don't find it :

 

  [3372/3682724720][Thu Feb 16 2017 10:37:10][SmObjKeyManagement.cpp:400][INFO]

   [sm-Server-04710] Key Roll over Request has been initiated automatically by Policy Server 

 

How can I solve it ?

 

Environment:

There is 2 environments: Web Agent 12.52SP1CR04 on IIS 7.5 64bit on Windows 2008R2; Web Agent Option Pack 12.52SP1CR04 on Tomcat 7.0.63 with JDK 1.7.0_65 64bit on Windows 2008R2; connected to : 1 Policy Store on SQL 2012 Always On in Compatibility 100 for 12.52 Policy Server 1 Shared Key Store on SQL 2008; 1 Policy Server 12.52SP1CR04;parallel environment: 2 Policy Servers 12SP3CR11 > 1 Policy Server 12SP3CR11 rolls the keys at 03:00 every morning; 1 Policy Store on SQL 2008 for 12SP3CR01 Policy Server

Resolution:

When a single Policy Server generates encryption keys in an environment with multiple Policy Servers that connect to disparate policy stores, but share a central key store, an additional registry setting is required. This registry setting configures each Policy Server to poll the common key store and retrieve new encryption keys at a regular interval

 

Setting Policy Server 12.52SP1CR04 registry key to 1 solved the issue : 

 

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Netegrity\SiteMinder\CurrentVersion\ObjectStore\EnableKeyUpdate= 1
