Performance Tuning Tool (PTT) is a Command Line Interface (CLI) utility that enables you to apply and list various profiles available in LMS server. Profiles consists of configuration files, which are in the form of XML files whose values are based on the recommendations for various applications. For more information on PTT features, refer to PTT Features.

There are two profiles shipped with LMS. You can use any of the profile that matches the system.

There maybe multiple configuration files that are involved while applying a profile. The parameters such as, snmp.threads.min, snmp.threads.max, ICSThreadCount, ICS DBConnectionCount, ThreadPoolCount, CDLNumOfThreads, max_db_connections, max_threads_for_config_fetch, EssentialsDMServicesHeapsize,ConfigJobManager.heapsize, and CDA_MIN_THREADS are tuned and available in each profile. You can apply the required profile to the system and improve performance. This is a major advantage of using PTT.

To begin, this is my environment:
Windows Server 2008 R2 Enterprise with 32GB RAM
Cisco Prime LMS version 4.2.3

First, we must stop the LMS service
net stop crmdmgtd

Using command prompt, navigate to:
C:\Program Files (x86)\CSCOpx\bin\rmeptt;

C:\Program Files (x86)\CSCOpx\bin\rmept>rmeptt.bat -show
The profile applied on this machine is: Default

C:\Program Files (x86)\CSCOpx\bin\rmept>rmeptt.bat -list
The profiles that match the OS in this machine are:
