Hardware / Software Maintenance
In addition to your normal system backups, TT recommends that you back up the TT directory structure (<root drive>:tt and its subdirectories) of the TT Gateway on a daily basis.
Additionally, TT installs files to other locations on the root drive. For extra insurance against complete system failure, back up the entire drive on which the TT directory structure is located.
TT is not responsible for maintaining third-party devices. Depending on the device, the exchange or the customer administers these machines, and it is their responsibility to maintain them.
If you have questions concerning a third-party device, refer to the appropriate exchange documentation.
To optimize server performance, TT recommends that you follow these guidelines:
- For all machines on the trading network, conform to the hardware and software requirements as documented in the TT Trading Systems - Hardware and Software Requirements document.
- For TT recommendations on optimizing machine performance, refer to the document called TT Trading Systems - Hardware and Software Requirements.
- Delete old log files on a regular basis.
- Map each TTORD trader to no more than one registered trader per exchange. However, you can map TTORD traders to different registered traders across different exchanges.
- To prevent overloading the server, map TTORD traders among registered traders so that you have as few as possible TTORD traders mapped to the same registered trader.
- Use a RAID array on the gateway server.
- Follow documented server optimization techniques published by Microsoft or your hardware vendor.
- Increase the RAM and use a higher speed processor.
On average, CPU usage on a TT Gateway Server should not run higher than 50%.
To check CPU usage:
- Right-click the task bar.
- Click Task
The Windows Task Manager dialog box displays. In the Performance tab, CPU usage displays in a graph and as a power meter.
If the CPU has a high usage percentage (above 50%) for an extended period of time, you must identify what is causing the problem.
To identify a CPU problem:
- Perform the procedure above.
- In the Processes tab, click the CPU column header to sort CPU usage in a descending order of percentage.
- If a TT process is using a high percentage of the CPU for extended periods of time, call the TT Help Desk.
