Performance Counters Now Supported in 64-bit Perfmon.exe

On 64-bit systems, all CA DataMinder performance counters are now supported in the default 64-bit version of the Performance applet (perfmon.exe).

Previously on 64-bit systems, most CA DataMinder performance counters were only supported in a 32-bit version of the Performance applet. This anomaly particularly affected performance counters for the policy engine hub when the hub was installed on a 64-bit Exchange 2007 or 2010 server.

If you previously used the 32-bit Performance applet to monitor CA DataMinder components on a 64-bit system, you must switch to the 64-bit Performance applet after upgrading to CA DataMinder 14.1.

Background

On a 64-bit Windows operating system, there are two versions of perfmon.exe:

• A 64-bit version is available in the \Windows\System32 folder. This is the main System folder for the 64-bit operating system.

  Why 'System32'? The folder name, an apparent misnomer, is a legacy of the folder naming scheme in earlier Windows operating systems.

• A 32-bit version is available in the \Windows\SysWOW64 folder.

  Why ‘WOW64’? On a 64-bit Windows operating system, there is an emulation of a 32-bit operating system called ‘Windows on Windows 64’, or WOW64.
