Overall Remedy system tuning

This topic discusses the following overall tuning strategy:

Optimizing the network

• Use a gigabit network with minimal latency between the AR System server and the database server.
• Do not to install a firewall between the AR System server and the database server. A firewall has significant negative impact on performance.
• If there is a load balancer or firewall between the mid tier and the AR System server, configure it so that idle connections from the mid tier are not severed. Reestablishing severed connections takes additional time.

Optimum client configuration

BMC Performance Team recommends the following hardware and browser combination:

• Dual Core 2+ GHz CPU with 2 MB L2 cache or single core 3+ GHz CPU with 2 MB L2 cache
• 2-4 GB RAM
• The latest Mozilla Firefox update (37 or later), Microsoft Internet Explorer 11 or later, or the latest Chrome update (42 or later)
• Disable all browser add-on toolbars and plug-ins except Adobe Flash
• Configure the browser to open pop-ups in a new tab
• Configure the browser cache setting to Automatic

For additional information, see Browser hardware requirements and settings.

Overall tuning approach

1. Create a precise statement of your performance problem. See Developing a performance problem statement and collecting performance data.
2. Review overall system performance and capacity of the following components:
   • CPU and memory resources
   • Memory consumption
     See Monitoring Remedy performance and capacity.
3. Review the following individual components:
   • Mid tier
   • AR System server

   • Database server

     Note

     Evaluate all components before making any changes.

4. Evaluate and resolve performance issues by doing the following steps:
   1. Identify configuration discrepancies and performance bottlenecks.
   2. Prioritize any proposed changes based on the problem statement.

   3. Perform and evaluate the impact of the highest priority change.

      Note

      Resolving performance issues is an iterative process. Evaluate one change at a time. Each time a substantial change is made, quantitatively evaluate the effect of that change before making another change.

5. Repeat step 4 for each change in order of priority.
