Performance Tuning Tool
Performance Tuning Tool (PTT) is a Command Line Interface (CLI) utility that enables you to apply and
list various profiles available in CiscoWorks server. Profiles consists of configuration files, which are in
the form of XML files whose values are based on the recommendations for various RME applications.
For more information on PTT features, refer to PTT Features.
There are two profiles shipped with CiscoWorks. You can use any of the profile that matches the system.
For more information on PTT Profiles, see Profiles and PTT.
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.
